Galaxy Zoo Talk
A satellite trail 😃
Hi - I have answered you in the discussion 😃
I would go with a post merger - you can still see 2 distinct cores to the galaxy - stunning!
I have a feeling it is l ready in the collection - it is very familiar...
Looks like a possible collisional ring - will add to the collection 😃
There is interaction - so I would not rule out merger 😃
There is no need for us to comment on every image, and this galaxy is well documented 😃 Look at NED - happy hunting!
what a stunning dustlane! #double_dust indeed 😃 From this angle I would say lenticular.
The colour is a bit odd for a polar ring. Usually the polar ring is more energised and full of young stars.
I would go with tidal trail.
Not artifacts 😃 Looks like we have a inner ring around the centre of the galaxy.The dots look a lot like ansae.
No - it is a artifact caused by a passing satellite. Wish the cause was as exotic as hawking radiation!
The bright object in the lower left of the galaxy is a foreground star. The galaxy is somewhat disturbed, but not from the star
There seems to be a similar 'red' steak through the galaxy to the left (off screen) in both DECaLS and SDSS. Alignment the same. Artifact?
I would say it is likely - see the star formation in the lower left? Also light tidal debris.
Filter issue - look at the image on DECaLS skyviewer - a lot of object are similarly discoloured. Remember these are composites 😃
That is a foreground star from our own galaxy! The brightness causes oversaturation that leads to interesting looking artifacts.
Not your eyesight! This a somewhat irregular galaxy or a proto spiral, the shape is down to clumpy regions of star formation
#dustlane
Yes it is - we call them artifacts. Happy hunting!
It is most likely to be more 'accurate' for the foreground source. That is all I have time for tonight - happy hunting!
The redshift or 'z 'is calculated from the spectra, if the spectra is composed of multiple sources it is not accurate.
I am not sure where you see star formation in the red galaxy behind - I am more interested in that it appears to be a red spiral.
3/3 IOW it is contaminated, and it is not very easy to split out what emissions etc... belong with what object.
2/3 When a spectrum is done it includes all objects within the line of site of its detector. So it can include multiple objects.
1/3 Spectrum is sometimes very misleading, and can lead to incorrect conclusions 😃 Always advisable to use your eyes first ...
The colour is not real - looks like a stripe of the image was not correctly processed,or a filter was malfunctioning when it was imaged.
2/2 There is also a dark band, most likely a removed artifact going through the upper galaxy. Hence the somewhat disturbed appearance.
1/2 In this case I am going to say no, it looks like a more distant orange spiral galaxy, overlaped by a warped edge on.
Nice!
Does not look like lensing - I would say it is a more distant galaxy that is being overlapped by the closer galaxy at the centre 😃
This was the first image in a long time that made me have a second look. Foreground stars, but it did make my heart skip a beat 😃
Looks like some post imaging processing was done. The discolouration always seems to fall in linear bands. Possibly artifact removal?
You can still classify it - even with the glitch!
Nice overlap in the upper left of the galaxy.
The galaxy is an edge - on with an amazing #dustlane. The colour itself is artificial, something odd going on with the filters.
Those are artifacts from processing - you can just ignore them!
The red thing is a foreground star from our own galaxy 😃
It could also be an overlap - looking at the pixelation, the resolution is a bit low. Likely in the same cluster. Merging - not so sure.
Sadly, we have no gravitational lensing in this image 😦 The alignment is just down to chance,
Wow - stunning #bar and #disk not so sure about a ring 😃
Just by looking, I would say unconnected with the galaxies at the center. From the structure of the 'arcs' - likely processing artifacts.
#polar ring
#disk #dustlane
#no_lens
#no_lens : a spiral arm, in a somewhat disturbed galaxy.
just #wrong_size - the rest is unusable - but thanks for the classifications 😃
Hmmmm - as in 6 o'clock?
or possibly dislocated?
Hmmm - not so sure about disturbed. We have a third arm just inside of the outer right one. The smudge on the left may be unconnected.
Not so sure about dust... where about are you seeing it?
Looking at the Spectra on SkyServer it is unlikely to be an AGN 😦
It is very bright, so could be an AGN - would need a Spectra to verify. Nice spiral structure 😃
The brighter,rounder, more defined ones are foreground stars from our own galaxy. The fuzzier ones are other galaxies!
I will go with no gravitational lensing.
No - look at the SDSS image.
No dust lane - sorry.
A #psuedo_ring galaxy -nice!
Regions of active star formation.
Perhaps in earlier surveys with lower resolution - but I would not classify this as a LSB in DEcaLS. Clearly defined features.
2/2 SDSS has them flagged as galaxies, and they don't have the roundness of foreground stars. Not much other info - on my follow up list.
1/2 This is a bit of an odd one - the placement on the arms would suggest clumps of star formation, but the colouring is a strange...
I would not go for elliptical in this case - rather lenticular or disk galaxy.
There is a possible hint of a polar ring - that would account for the odd shape 😃
It is an artefact caused by over saturation.
Currently interacting with another galaxy, so that rules it out of the double dust category.
Hmmmm - not so sure - I was going to discount it, but it could be the angel we are viewing it. Interesting non the less.
The image is unclassifiable - it does not have the correct resolution.
Not a fan of the simulated galaxies myself.... this could be a multi-armed galaxy with star formation at the tips
#wrong_size
Remember to only classify the object directly at the center! The other objects will get their own chance to be classified 😃
It is an optical artifact caused by over saturation. The object was too bright for CCD camera!
There might be a second (more undefined) arm to the left and perhaps a third to the bottom. Well, three armed galaxies are also rare!
I am not thinking a dust lane - but rather a spiral arm 😃 Nice - single arm galaxies are quite rare 😃
The colours of the DECaLS images are different to SDSS - they all seem a bit 'whitewashed' - star formation will be more vividly coloured.
Where?
Edge on galaxy with another galaxy overlapping.Not a merger and certainly not a clump of star formation within a galaxy 😃
Could be a shell galaxy - the green and red lines are artifacts.
Sorry - where are you seeing signs of starformation? Just looks like an old elliptical galaxy for me 😃
Yes - the distortion and tidal features are all due to the merging or interaction of multiple galaxies. Lovely!
These are all just over exposed out of focus stars from our own galaxy - The Milky Way
This (and all other Illustrisi images) is a simulated galaxy - in the past you have been classifying real objects:-)
Hmmm - not so sure about lensing. The colour looks wrong in the SDSS image. Possibly just chance alignment.
The black / purple blob are artifacts caused by over saturation - you can ignore them 😃
Sorry no lensing - a group of galaxies #no_lens
Yes they are - in a case like this classify as star / artifact and move onto the next image. #wrongsize
Yes - an artifact #decalsredartifact
Only classify the object directly at the center- the other objects (ITC foreground stars) can be disregarded.
The red line going through the image is an artifact called a diffraction spike caused by the red object to the right (a foreground star).
Sadly not - this is a simulated galaxy. \the blue ring are areas of star formation.
I think the two central galaxies are overlapping and not merging - not seeing any interaction.
#blank
or #overlap - not seeing a lot of disturbance in either. Interesting either way 😃
I would go for a slight bar and spiral features - lovely!
I would classify it as one - but the sims are difficult to class 😃
The current images from the DECaLS survey are almost at an end - so at this point it is the uncompleted images...
It is a star - the missing area is due to over saturation / over exposure. Stars are closer than galaxies 😃
According to one of the project scientists they are asteroids 😃
Not boxy or a edge on - sorry!
That is a foreground star off screen to the right 😃
Once again -no need to go through old SDSS images for multiple dust lanes - we are specifically interested in the current survey. Thanks! 😃
It is a single galaxy, with a single source at the center. So I am not too sure what you are referring too? You need to be more specific 😃
Did you just get this to classify?
It is important for the Scientists to find out if the sims are valid models. What better way than to get us to classify them 😃
No, not irregular enough to be an irregular galaxy 😃
Wow - looks like a cluster. Lots of references on NED. Not too sure how the scientists would of expected to classify it?
Yup - #blank
Not x-shaped - more likely round - Sorry!
Possibly a early merger, no way to tell.
No gravitational lensing - Illustris are not capable of generating GL's. No artifacts either - this is a sim placed upon a real background.
There are tidal trails & distortion in the shape of the galaxy - but with these Illustris sims it is difficult to tell, and no right answer.
Unlikely to be gravitational lensing - more inclined to go with shell galaxy. Would need to do a bit more research - interesting indeed 😃
The red spots are foreground stars. Looks like a normal Illustris sim otherwise 😃 Happy Hunting!
Hmmm, Looks a bit too diffuse to be a star - more so in the SDSS image. I am more likely to say galaxy. Nothing on SIMBAD.
Hmmm - we would call this one #blank
I think I might go with star for the central object.
followed
Most likely an overlap - but interesting red #lens in the 11 and 9 positions of the galaxy. Will look into it more tomorrow 😃 Nice find!
Interesting image. Will have a closer look...
Wow - what an amazing merger!
It does look somewhat asymmetrical - cant see any active merging going on. Not too sure!
Not a lot of interaction, I would personally go with overlap.
It is an optical artifact caused by over saturation or over exposure by a bright object - in this case a foreground star.
The green and the red lines are both optical artifacts from when the image was captured. Could be bad pixels / dust etc.
Looks like 2 separate galaxies, the orange one on the right and the younger galaxy with lots of blue star formation on the left.
That looks like an optical artifact. Possibly an asteroid.
#pseudo-ring
No, the Illustris images sadly do not contain any gravitational lenses. Looks like a shell galaxy.
Popular galaxy - 62 references on NED!
Lovely #ansae and #bar too! Hmmm, looks like 2 bars at right degree angles.
nice #round-bulge 😃
Link here and zoom out.
That is one awesome artifact 😃 Check it out on 'examine' - you can see a 'reflection' of the mirrors of the telescope 😃
Try searching for a virtual observatory, such as SkyView, and read the tutorials to get started. Remember they are not affiliated with us.
Most likely an artifact since it is only visible in SDSS. The colour suggests it was just present in a single band. Check another survey?
They do, but are very rare. Sadly the redshift between the center galaxy and the upper right are very similar. Still a nice addition 😃
No not an irregular galaxy. Looks like a edge-on galaxy overlapped by a foreground star (on the right) with a non interacting galaxy at 12.
Interesting.Not as clean as the original but very nice indeed!
Excellent find 😃
I guess this is meant to simulate a polar ring
Compairing the SDSS / DECaLS images the purple blob at 4 and the green blob at 12 are the same object.
According to the experts a asteroid in the DECaLS images 😃
Definately a #edge-on, not so sure about a polar ring 😃
Another #wrong_size image 😦 Really sorry about that! Looks like the computer had a bad day when it generated these images.
That is a foreground star from our own galaxy, the colours are artifical. Happy Hunting!
#edge-on galaxy
The brighter round object on the right is a foreground star, so no overlapping!
Wow- what an awesome merger, and the galaxy at 11 is the culprit of all the chaos 😃
In this case I think I would say spiral, but it is possible there could be an inner ring hidden in there!
We have been told artifact like that are actually asteroids!
That is an optical artifact caused by imaging. Not visible on the SDSS image. Happy Hunting!
#polar-ring #polar
No, unlikely. If the redshift is correct, the distance separating them is quite vast.
The SDSS object looks like an asteroid for me.
At the center? Either a 3-armed spiral or a disturbed 2 armed spiral
#collisional-ring ? [24]
#collisional-ring [22]
Perhaps a bit too complicated to include in the #collisional-ring collection 😃
#collisional-ring [20]
#collisional-ring ? [19]
#collisional-ring ? [18]
A foreground star in line of sight of a much more distant galaxy.
Not a voorwerpje - a LSB proto spiral. AGN clouds need a AGN at the center of a host galaxy in order to be visible.
#collisional-ring ? [13]
#collisional-ring [12]
#collisional-ring [10]
#collisional-ring ? [9]
#collisional-ring [8]
#collisional-ring ? [6]
Sorry, I don't think that is one. It looks like an irregular galaxy. The ring would be more defined if it was one. #no_cr
#collisional-ring [1]
#collisional_ring same as AGZ000bgrj
#collisional-ring [3]
Nice! #3_arm spiral!
According to NED and SkyServer it is a star. No spectra.
Another #wrong_size image 😃
They are simulated galaxies from the Illustris dataset, the blue patches of star formation seems to be a common feature of them.
Sorry about that! Some of the images are the #wrong_size.They will get removed from the dataset at some point.
#wrong_size #decals_red_artifact
Not lensing - a couple of spiral / disk galaxies overlapping the central one #no_lens
Not gravitational lensing 😃 Star formation in a simulated galaxy #no_lens
#collisional-ring [26] perhaps?
Not so sure 😃 What galaxy 'has it / is it' interacting with too cause tidal debris?
No, not sunspots. Regions of active star formation.
Um, with what?
Not a lens - I would say star formation in a spiral or ring pattern 😃
I would not call this disturbed - it has a lovely symmetry 😃
A foreground star - classify as a star / artifact and move onto the next one!
Artifacts - bad pixels is my guess. You should still be able to classify the galaxy beneath 😃
it is an artifact - it is not real, not too sure what causes it though. #decals_red_artifact
Edge on disk galaxy, slightly disturbed. No visible culprit. Hmmmm.
#overlap
#x-shaped
Depends on what feature you are looking at 😃 We have a bar, middle ring and a pseudo ring! Lovely galaxy 😃
It is an artifact. If your look at the DECaLS examiner you can see it is a diffraction spike from an extremely bright star, off screen left.
But what a stunning galaxy! Someone should nominate it for the daily Zooniverse 😃
It is a simulation - the blue bits are star formation within the galaxy.
As soon as a galaxy has any features it is no longer an elliptical galaxy. I will admit it is difficult with these sims... 😃
Could very well be - most noticeable at 4 to 7. Remember to tag it as shell_galaxy with the hashtag in front 😃
Ansae are always appropriate when there is a bar involved 😃
That is a lovely one!
Just curious, why do you think it is an AGN? just the brightness?
#no_lens - star formation.
The right looks like it could be a barred shell galaxy?
Sometimes with the sims it is impossible to tell! I would ignore the star on the left and just attempt to classify the central galaxy.
Sadly not - lensing is not possible in the Illustris images, the model wasn't programmed to include them.
A #blank Illustris image - looks like they forgot to add the sim 😃
Star-formation...
See this discussion regarding Illustris images and gravitational lensing.
That is an optical artifact called over sataturation or over exposure. The star was too bright for the camera (the CCD)..
For galaxies this would be a good starting point: http://ned.ipac.caltech.edu/level5/Sept11/Buta/paper.pdf
Not so sure about QSO - spectra looks quite flat and uninteresting 😃
It is a foreground star from our own galaxy 😃 The center is over exposed.
The bright object at 8 is a foreground star 😃
That is an artifact - imaging error.
Just coincidence - it is just by line of sight they look like they are connected 😃
They represent star forming regions in these Illustris simulated images.
The red line is an artifact - I can see several similar lines in the image. Thinking slight displacement of the image stacking.
also #wrong_size
To the right? or left? I get confused all the time 😃
Correct- very bright objects tend to over whelm the camera!
Awesome ansae! (ansae = the extended arc like blips at the end of the bar)
Yes 😃 The blue bits are regions of star formation! I think I might of commented on this 'galaxy' before - see right 😃
Not an edge-on, a barred spiral galaxy that was a bit too zoomed in. Sorry!
nice #bar with #ansae and perhaps #ring
The arms almost wrap around the galaxy so I would go with medium- personally!
Remember to only ever classify the object directly at the center. Cheers.
A foreground star from our own galaxy - the black bits are areas of over saturation.
Not an irregular galaxy - just a sim with star formation. Sorry!
No, just a single galaxy with at least 6 regions of star formation. The orange blob on the right is a foreground star 😃
#blank - classify as a star / artifact and move onto the next image 😃
It is a bar:-)
Almost edge-on or disk galaxy 😃
Aye - the algorithm gets confused with really bright objects.
A barred spiral galaxy - I am useless at telling how many arms! Gut instinct says more then four 😉
A #decals_red_artifact - it is not real just a imaging artifact 😃
No 😃 The Illustris images are sadly not capable of generating gravitational lensing.
Mmmm, Could also be a couple of foreground stars on the right. Galaxy is certainly merging, nice tidal tails!
It is a foreground star - classify as star / artifact and move onto the next image 😃
The orange objects on the right are supposed to be foreground stars.
A nice smooth galaxy composed of billions of stars!
#bar #ring #psuedo_ring
The red streaks? Yes - artifacts.
One very disturbed galaxy! Still love the dustlane, not quite what we are looking for, but will keep it in for now 😃
Not so sure about this one.... but the spikes on the right are interesting. Included 😃
Looks like we have some nebulosity 😃
Classify as a star / artifact. It is a foreground star, the dark blue area is a artifact caused by over saturation of the CCD.
No, just optical artifacts - not too sure what causes them though!
It is a #blank Illustris image - just classify as a star / artifact and move onto the next image 😃
Read comments below 😃
You can have star formation in a galaxy, without it having to interact / merge with another galaxy!
Nope - I don't think so. Looks like a smaller somewhat irregular galaxy with star formation.
A galaxy 😃 Galaxies are a lot more fuzzy than stars!
It is a foreground star - the 'missing' pixels are caused by over saturation on the CCD camera.
It is an artifact caused by imaging. Looks like it could be some bad pixels on the CCD camera.
Ooops - a #blank Illustris image! Sorry!
It will get it's own chance to be classified in a separate image 😃
The red line is in fact an artifact extending through the image 😃
Irregular is a class of galaxy, so I would say no. It is a simulated galaxy with clumps of star formation
Sorry Kyle - need to #no_lens it, to remove it from the GL collection.
Wow - this could be the first #illustris_arc ! Nice find!
I would classify the central galaxy as a merger with tidal tails - it is clearly interacting with the other 2 galaxies. Nice!
The bright round object? That is a foreground star from our own galaxy. Happy hunting!
This is normal for the Illustris simulated galaxies -we are seeing a lot of similar combinations.
I don't think it is two separate galaxies, to have that precise alignment would be uncanny, have you tried downloading the FITS images?
The red line is an artifact, but it shouldn't stop you from classifying the galaxy behind it! 😃
Classify ass star / artifact - it is a really bright star off to the right of the image 😃
It is an optical artifact caused by the camera - it is not real 😃
Hopefully the other galaxy will turn up in another image! Looks like a good candidate for the DD research 😃
It is the correct size - not much else you can determine from just looking at it!
Not really - the algorithm determined the glactic center to be the blob on the left. Understandable if you look at it with human eyes 😃
Looks like it is supposed to be an overlap with a more distant edgeon.
If I was classifying I would say interaction - it will be impossible to tell for sure without seeing a zoomed out image.
They both have the same redshift - so #merger for me.
Not a merger! A stunning #pseudo_ring along with a bar.
They are clumps of star formation within the galaxy. Young stars are hot and blue. Hope this helps!
I would go with star 😃
This is a galaxy - see below 😃
What a lovely one! Nice #dustlane too!
Disturbed, lots of interaction - I would say #merger 😃
It looks like it, but it is sometimes difficult to tell with these simulated galaxies 😃
I would of classified it has having a ring too!
The blue bits are star forming clumps in the galaxy. The red objects look like foreground stars for me.
Not a lot of interaction, and only 1 has a redshift - I would say overlap.
Yes - #dustlane 😃
I would say so - remember to tag it!
I would say the orange object is a foreground star, and SkyServer agrees 😃
Stunning! and welcome to Galaxy Zoo 😃
There is a line (an artifact) going through the entire image, the bright object on the right looks like a foreground star.
Correct! A star off screen to the top left. Remember to only classify the central object 😃
The bright object with the spikes? That is a foreground star from our own galaxy 😃
#merger - looks like the top right galaxy has gone straight through the central one! #collisional-ring [25]
Yup - this is quite exciting, but, we need to find more of them!
Just posted it.
A foreground star - sorry!
In what way? 😃
#double_dust - see related post for details 😃
#decals_red_artifact
Nope - no gravitational lensing. The bright red object is a foreground star.
Yup- same goes for stars - but with new technologies / telescopes coming up the data could change. Need to be flexible 😃
Just looking at this image - I would say merger.
140 characters is not a lot to type in! Long and short - you need a spectra to record an AGN, it is not just about luminosity at the core.
Knowing the composition will allow you to make a very educated assumption about the nature of the galaxy, including about having an AGN.
Nothing to do with DECaLS! I just find X-ray easier to analyse, should be the same with optical. Spectra is the key, to see the composition.
Personally, I am now prejudiced towards x-ray 😃
A spectrograph in either optical or x-ray is efficient enough. A visual classification alone is sadly lacking when classifying AGN's 😃
Eeeewwwww - I hate spiders!
Slight shell on the lower right, just over half way to the edge.
Not likely 😃 most likely a satellite or background galaxy. A arc or lensed galaxy will be different in colour to the lens itself.
lol - just a bad column of pixels on the CCD.
Cheers - any Illustris images?
Look like the Android app hasn't been updated to the latest Survey... I have left a msg for Kyle.
The large bright object at the lower left edge of the galaxy? Foreground star 😃
Star formation for me. I can see 3 similar coloured lumps in rightside of galaxy - to me they follow a spiral pattern. Would be nice though!
Usually, the cross section is really small. You should be able to find it online.
If there are multiple objects within the strip of the spectrograph, then yes, the spectra will be a combination. Not always bad.
Looks like there is tidal debris (culprit top left?), so that could skew the spectra results. Definitely not AGN Clouds.
@themis_koutras - Can we try not posting in CAPS - it is considered shouting. Many Thanks.
Double post!
No 😃 x-shape is a tag reserved for the shape of an edge-on's bulge. Examples here
I would just go with a ringed barred galaxy. Hoag Objects are formed by galactic collisions 😃
just tag them as #blank - it will help the scientists in the long run 😃
I am going to go with artifact - like you said it is way too straight to be gravitational lensing 😃
I am going to go with overlap - not much distortion in either galaxy. Lovely image!
It has a redshift of 0.07, so it is not local. Elliptical Galaxy for me 😃
They have a very symmetrical structure, so I would not class them as tidal debris. I would personally say spiral arms. #bar #ring #resonance
wow - an inner and outer ring. #ansae also - lovely!
A very luminous object - I would go with a foreground star.
Looks like the image was incorrectly sized - I can see how it will be really difficult to work out what to classify in this one! #wrong_size
My point exactly! Keep things simple!
Not that I am saying this is an elliptical galaxy - but each to their own:-)
For clarification - ETG = Elliptical galaxy - and that is an assumption. "Engineering Technology Group" seemed unlikely as an alternative.
Hi Jean, please try not to use acronyms that have not been commonly used on here before - they are not newbie friendly 😃
Just tag it as #blank and move on 😃
What a #dustdane! In fact is that a double? or just a reflection? Will flag it up.
#wrong_size too!
😃 October?
Perhaps 7 ????
Maybe 5 or 6? But I am useless at counting arms. Perhaps someone has a better idea?
Another incorrectly sized image #wrong_size
To create a link to another image you just need to put in the ID like so: AGZ0009wd5 - the link is automatically created.
Shell galaxy with star formation for me.
#merger for me 😃
Correct! It is a foreground star!
I would go with smooth - there are no features - nothing to indicate it is a disk. Just my personal opinion.
#decals_red_artifact ?
We should tag these with #Decals_Red_Artifact
Thanks! I will have a look and get back to you in the thread.
The 'blue stuff' are regions of star formation. Looks like a satellite galaxy.
At the centre? No, a edge on galaxy 😃
I would go with all of the above 😃 #merger
Another DECaLS red artifiact - we really should collect these!
What a stunning galaxy! By 'stain' do you those dark patches?
See discussion on the right 😃
Yes, looking at the colour and shape I would also say artifact.
No gravitational lensing 😃 I would go with a loose possibly 3 armed spiral. Thanks for your help!
Looks like a late stage merger to me. I am sure I can see 2 slightly distended core on the right. Anyone else?
Looks like it 😃
#zgotw #dailyzoo 😄
Yes - I would go for an #x-shaped bulge.Nice one!
2/2 team do their work and when the result are presented, comment on it then. Also consider that your words may influence other volunteers.
1/2 @JeanTate - yes, but you made a statement ("another unreal sim") without having analysed the data. What I am saying is let the science
@JeanTate - let them analyse the data before making a judgement 😃 If you feel different - there is no reason for you to classify.
The apparent increase in QSO's may also be a side effect of deeper imaging - not necessarily QSO's - just more photons being captured!
...and that is exactly why we are classifying these simulated images, so they can compare the data against real galaxy classifications.
Sorry I am not seeing any gravitational lensing in this image.
No it is not - in the Illustris images blue indicates star formation. #no_lens
Hmmm - I do see a ring of sorts, does not have the morphology of a pseudo ring - no so sure what I would call it.
Looks like a spiral arms wrapping themselves around the galactic core for me 😃
The blue fuzziness indicates regions of star formation in these simulated galaxies - hope this helps!
Aaahhh - good to know!
The orange object below the galaxy? more inclined to go with foreground star 😃
The blue regions indicate star formation - interesting how they follow a spiral pattern in this simulation 😃
Star formation apparently! Cant help but remark on the shell like structure once again!
Hmmmmm - star formation is often triggered by merging. They seem to share the same halo - early stage merger for me 😃
@wtaskew - Just for interests sake 😃 How do you define a gpair as opposed to a merger? Previous classification? or visual inspection?
Love that - swagalicious 😄
Also, some disturbance on the right of the smaller galaxy.
Aye. You can see a tidal trail from the smaller galaxy on the right, crossing over the top to the left of the larger galaxy.
Yes - I know the colour of the images are different - but the structures is quite similar 😃
I was almost thought this was a IIlustrius image....until I looked at the tag. Awesome 😃
No lensing - looks like we have a dustlane and a very strong #x-shaped bulge. Certainly very interesting 😃
No - I don't think so, but I am sure @kwillett would be able to confirm 😃
For the bright purple bit, I would say artifact. There also seems to be a smaller, greener line beneath it - @kwillet ?
Yeah - I would also go with merger - nice tidal debris
Possibly a simulated Shell galaxy?
Not so sure this would be classed as an irregular galaxy - seems pretty regular 😃
Another DECaLS star that gatecrashed the dataset 😃
Not sure - I will have to research what GL's would look like in in DECaLS images. Will need a few days.
cool - will spread the word!
@kwillet - how do you want us to tag these ones? Blank may also include previous surveys...
#blank_illustris
It is an overexposed foreground star - are you using the mobile app to classify?
It is one of the illustris galaxies - they all seem to have a slight blue discolouration near the nucleus.
QSO = Quasi Stellar Object
I would love to know why do you think it is an AGN? Just the brightness? or did you find a corresponding spectra? 😃
As all these images are classified by multiple volunteers it is highly likely the disk galaxy was picked up and correctly classified!
Foreground stars that the algorithm mistook for galaxies! Classify as a star / artifact. Happy Hunting!
The smudge at the center is indeed a nondescript galaxy, the ball on the left hand side looks like a foreground star. Happy Hunting!
All foreground stars - to be honest, comeback tomorrow and classify - we will have a new survey 😃 Way more interesting!
All fore ground stars 😃
Read below - not a gravitational lens - just foreground stars masquerading as one!
Correct - all of the objects in this image are in fact foreground stars.
An irregular galaxy with intense regions of star formation.
This is a galaxy, but looks like the filters were slightly misaligned - hence the two toned colour effect.
Yes - foreground str from our own galaxy.
Most definitely a #bar - nice #ansae at the ends 😃
Hmmm,don't think so - perhaps spiral arms? The resolution of the galaxy is not that good so it could just be empty space.
I am going for galaxy on all accounts - nice cluster 😃
Classify as star / artifact - an exposure from the early evening when the sky was still too bright to image. Happy Hunting!
Thank you 😃
Yup- agree
You are correct! All the objects arein fact stars from our galaxy 😃
Nope - an irregular galaxy with star formation. A single galaxy - no merging.
No, most likely a starforming region within the galaxy. We would see more disruption if this were a merger 😃
Go with your initial instinct - there is no wrong answer 😃
Not an irregular galaxy - I would go for spiral features,barely noticeable nucleus / bulge.
Welcome 😃 Classify as a star / artifact, all theobjects are out of focus, over saturated foreground stars. Happy Hunting!
Yes 😃 Artifact - all these objects are out of focus foreground stars.
No signs of a ring - a edge on galaxy slightly warped
Foreground stars - not necessary to tag them as 'bugs' - just classify as stars / artifacts and they will get removed from the dataset.
Correct - all of the objects in this image are foreground stars. Classify as star / artifact and move onto the next image.
If you check the redshift (Z) of both objects, you can estimate whether the objects are at a similar distance. Have you had a look?
Always classify the image directly at the center - in this case the smaller purple blob on the left (which happens to be a foreground star)
Not a galaxy- a foreground star from our own galaxy. The weird colours are due to over-saturation.
Not a nebula - a galaxy with rich starforming regions 😃
That is a foreground star from our own galaxy - they tend to get in the way when we are observing much more distant galaxies!
The telescope wasn't tracking correctly - hence the 'double' objects. If the exposure was longer we would see trails.
Not a sattelite trail - a diffraction spike from a bright foreground star off screen to the left 😃
I would say so 😃 The central galaxy is in the process of merging with the orange galaxy in the top right.
Hmmm, difficult to tell in this image. We do have a lot of stars, but the orange blob in the centre looks like a galaxy to me.
Lots of star formation - so still in the process of forming. You can tell by finding out what atoms and elements are present in the galaxy.
No worries 😃 Lots of people will classify this image, so I'm am sure it will be flagged as having a bar. Thanks for your help!
Neither galaxy has a spectra associated with it, so visual inspection is most likely the extent of the investigation.
😄
Always classify the one directly at the center, in this case it was the tiny one you classified 😃
#merger for me
I would go with 2 galaxies merging - stunning!
Out of focus foreground stars
A stunning 2 armed barred spiral - nice!
Hi @jdmonk - It is not a galaxy, rather out of focus foreground stars. 😃
Always classify the object directly at the center - in this case it is most likely a foreground star 😃
They are out of focus foreground stars - classify as a star / artifact and move onto the next image 😃
Instructions here
That is a diffraction spike from a bright foreground star off screen to the top. Have a look on SkyServer for the zoomed out image.
Classify as a star / artifact - this is a star from our own galaxy. The weird colour / shape are imaging errors.
Could also be an #overlap - the photoZ of each galaxy indicates they are quite distant from each other.
Out of focus foreground stars.
A central galaxy overlapped by foreground stars 😃 Stars tend to be whiter and more round in the SDSS images. Hope this helps!
I would go with foreground star 😃
Classify as a star / artifact - it is a foreground star from our galaxy. It is also out of focus and misaligned.
Classify as a star / artifact 😃 Imaging errors from the edge of the observing field.
Yes - a stunning merger. Have a look on SkyServer for the zoomed out image. (link also in the comments below)
The bright one lower left? A foreground star from our own galaxy 😃
Imaging errors (could be equipment or environmental) - just classify as star / artifact and move onto the next image.
Correct!
Edge of one of the observing stripes - mark as star / artifact and move onto the next image 😃
Not a lot of interaction, so I would go with #overlap. Lovely edge-on!
Looks like two galaxies merging 😃 Lots of star formation too!
Aye - an artifact. Edge of the stripe / field.
The FAQ's are correct - if there was a green blob along side the other two then we may consider it an asteroid.
Not an asteroid - it is an artifact. If you look on SkyServer all the objects close by have similar errors.
No gravitational lensing at 5 - that is a edge-on galaxy.
An artifact caused by imaging / processing errors. Classify as a star / artifact and move onto the next one 😃
Also, I am looking at this image on my mobile - don't have access to NED/ SkyServer, so can't access additional resources.
Yup... agreed. Not convinced it is an arc, but the curvature is good. Concerned about colouring - should be more blue or possibly red.
The smallest of the 'cores' @ 2 is a foreground star. The others are ansae - star forming regions at the ends of bars.
😃 agree
@fishpond you need to include a word along with the hashtag for it to be useful 😃
Nope - not an irregular galaxy.
où?
I don't think so - the PhotoZ is quite different and no interaction between the two. A accidental line up 😃
Just classify what you see 😃 There is no right or wrong answer. Personally - 2 armed barred medium spiral
Correct! A edge-on galaxy at the center and several foreground stars.
It is an artifact caused by oversaturation. Have a read of the FAQ thread for lots more info on various artifacts etc..
Looks like a resonance ring and a bar - nice!
Yes:-)
The blue one - you can check the redshift values on SkyServer. They actually are quite close - relatively speaking 😃
WOW indeed! #ZGOTW
Usually, yes - blue galaxies tend to be closer to us, red galaxies are futhur away. Not a lot of interaction.
Not a edge-on galaxy - a disk galaxy with an awesome #bar! Nice!
I see what you mean - difficult too classify - I would of gone for smooth, in-between myself as there are no clear features.
No need to flag it here - just classify as star/artifact and move onto the next image! It will get removed at some point 😃
That is a foreground star from our own galaxy 😃 More info here
Not really - it is an artifact, so it is the result of imaging / processing errors.
Could either be a satellite galaxy of the larger central one or a foreground star. SkyServer thinks it is a star, but too diffused for me.
Hi @khutzel2 - this is a foreground star. Read below for more info.
SkyServer is not always correct - that is we come in 😃 This is a foreground star, no info on NED
We do have a edge on galaxy at the center, but the bright green object on the right is a foreground star.
3/3 .. it is the scope not the object that has moved. Best I can explain in 140 characters or less.
2/3 .. blue blobs in an image. It is the same object just captured in a different position as it moves. Ditto for misalignment, just ...
1/3 Yes - 'cause each of the filters are stacked on top of each other. The same way you would see a asteroid as separate red, green and ..
As for the colours - caused by oversaturation and stacking / filter issues - the colours are not real - they are added afterwards.
No way to tell without knowing the redshift of each of the stars - could just be coincidence down to line of sight.
I would not go with round - the galaxy has faint spiral arms. Disk / spiral galaxy 😃
Also a slight misalignment between the 'r 'i and 'z filters - look at the raw images in GZ examine.
Read below 😃
It does look like it - but no 😃 These stars are way fainter and in a different part of the sky. A coincidence 😃
I would go with: features, not a edge on, no bar, not a spiral and possibly something odd. Just do the best you can on what you see 😃
An #irregular galaxy with clumps of starformation.
A very bright foreground star 😃
Wrong colour for a supernova in these SDSS images - they would be a intense blue / green.
Just a out of focus foreground star with optical artifacts. Not a spectrum, sorry.
It is a galaxy with a dustlane and regions of active star-formation. Read below for more info 😃
The filters are slightly misaligned - so the red and blue images are not correctly stacked.
No:-) starformation
The dark spot is an artifact caused by oversaturation. The CCD camera got overwhelmed by the brightness of the galaxy 😃
Artifact for me - foreground star that is out of focus.
Intense regions of star formation - otherwise known as starbursts 😃
SkyServer has a spectra of the buldge - star forming region. Looks like quite a young galaxy.
#artifact
The object on the left is a foreground star - the black line is an artifact caused by oversaturation. Happy hunting!
Only visible in the 'r filter so I am going with artifact.
#artifact personally - there is not a lot that could be determined from this object 😃
2/2 We have a galaxy at the center, but the white / blue objects are foreground stars - I would classify as a smooth / inbetween galaxy.
1/2 First off - welcome to the Zoo @oldgeorge ! There is no such thing as a incorrect answer, the answer will balance out in the end 😃
Overexposed and out of focus foreground stars 😃
Not very disturbed, so I would be likely to say overlap.
Not a galaxy 😃 A over exposed foreground star!
Yes - I would say that most of the objects in this image are foreground stars 😉
Sadly it is not a merger / gravitational lens, and the galaxy does not look too disturbed. We have a lot of foreground stars in the image...
Not normal - an artifact caused by imaging / processing errors. BTW all the object in this image are foreground stars.
At the center? or too the left?
I would be lying if I said I understood all of it either 😄
Nope - a star /#artifact
My bad - I should of said 'quasar' not AGN in my previous posts - I was responding to the previous comments.
Um, are you asking a question? or saying the previous poster was wrong?
Good to have you back 😄
Does anyone have the original source classifying this as an AGN?
Hmmm - Having just read the paper myself - looks like this is not an AGN but a NELG (narrow emission-line galaxy)
It is quite likely 😃 We are almost coming to an end with the DR8 SDSS images - but you are the first one to comment on it!
Yes - I would agree- foreground star in the line of sight of the galaxy.
The green object is a gas cloud on the outskirts of the Orion Nebula: Link to SkServer where you can zoom out.
A galaxy - but with several foreground stars obscuring it 😃
These are in fact foreground stars from our own galaxy - the weird colour and oddness are all optical artifacts. Classify as star / artifact
Yes - most certainly a foreground star 😃
These are all foreground stars from our own galaxy - the strange colour are optical artifacts.
A galaxy - does not have the electric colouring of a voorwerp.
A foreground star.
Most likely 2 foreground stars - the weird colour are downto artifact from imaging / processing.
I would go with a lovely spiral galaxy!
Not a merger but it is an artifact! Three foreground star, the strange colors are artifacts.
at the bottom left of the image? or at the central galaxy? Need to know, so I can analyse what you are referring too 😃
An artifact - foreground stars mixed with imaging errors 😃
Certainly has the luminosity and definition of a AGN, but still trying to find a spectrograph to confirm...
Also has a bar and undefined spiral arms - so it is definitely not an elliptical 😃 So no need to use the hashtag #justsaying
Another galaxy - looks somewhat edge on. Also has a diffraction spike going through it from a star off screen to the right.
On the right? There are several little things in the image 😄
...for a zoomed out image. link - after clicking select 'get image'on the left.
They are optical artifacts - a diffraction spike and arc caused by a bright star off screen to the left. See the link in the next post...
The green line is an artifact caused by a satellite - as it only gets captured in a single filter we only see it in a single colour! 😃
The object at the direct center or the blue object slightly off center to the left?
Not an artifact 😃 This is in fact a galaxy - the filters might be slightly misaligned, but you should still be able to classify it.
The blue dots on the immediate center left are star forming regions in the spiral arms. The lower blue white dots are foreground stars.
Yes 😃
More common than we would like - out of focus foreground stars. Caused by imaging issues on the scope.
A #collisional-ring galaxy - nice! [2]
Sorry, not an irregular galaxy. A bunch of foreground stars in the line of sight of a galaxy.
The top left objects are stars from our galaxy- the effects are optical artifacts.The galaxy at the center is more interesting-double nuclei
Foreground stars from our own galaxy.
Not so sure about merger! The two galaxies look unconnected to each other and the photoZ is of the two are quite different. Sorry!
The fuzz balls are all foregrounds star - just classify as a star / artifact and move onto the next image.Thanks!
All the objects in this image are stars from our galaxy. Classify as star/artifact
The red object is a foreground star from our own galaxy - so unrelated to the galaxy at the center 😃
Skyserver has it classed as a foreground star and just looking at this image I would agree.
The blobs are areas of intense star-formation or starbursts - so yes, please do tag it as interesting!
Sorry - not an Irregular galaxy - I would go for a two armed spiral.
Not a comet - a young edge-on galaxy with star formation. Nice!
Not so sure about a ring 😃 Most likely spiral arms folding back on themselves. You could tag it as a #pseudo-ring
That is one seriously disturbed galaxy! So I would say it is connected 😃
#imagesizewrong
This is a real galaxy - the 'pixels' are background noise. This galaxy is 440,700,000 light years away 😃
Yes it does! It might be easier to make out if you try to use the 'invert' feature 😃
We are all newbies once - and welcome to the Zoo 😃
2/2 .. and take it from there. Did you try the 'invert' feature when classifying? I find it helps a lot!
1/2 Just looking at this image and not SkySever, I would not classify this galaxy as a edge on - I would select 'features/ disk'...
It is an artifact from when the image was captured / processed. It is not real 😃
It looks like an inner ring close to the nucleus of the galaxy.
The black line through the galaxy is an artifact - caused by multiple fields being put together to create a single image.
One of the more difficult 'u band images I have had to classify...
This is one of the images that got zoomed in too much - really sorry 😦 #imagesizewrong
Looking at the spectra it doesn't look likely - it does not have the high emission line of H alpha that we would expect from AGN's
What object do you think the central galaxy is merging with? I am not seeing any interaction myself 😃
The line is an processing artifact - it is the point where two SDSS imaging fields have been joined 😃
Looking at SkyServer I would say it is most likely a foreground star. Supernovas have a very distinct colouring.
What do you mean by bug? Or are you referring to the artifact going through the image?
Both look like overlaps for me - no interaction, they just look they are connected by line of sight.
2/2 assume you are talking about the central object. If you are talking about the round blob @12 at the top edge - it is a foreground star.
1/2 Can you please be more specific about the object you are referring to? Unless you make reference to the position of the object we will..
#barred #spiral
You can get blue ellipticals - but this is not one. Ellipticals are void of all features - this galaxy has clear spiral features.
No - we can see some faint spiral features and possibly a bar, so I would go down the 'features / disk' route. Ellipticals have no features.
It is one of the zoomed in images - #imagesizewrong
#bar #spiral
Wow - the bar wasn't even visible in the 'u band - nice!
Nuclear rings are close to the core of the galaxy and are within the ends of the primary bar. This is not one - would go with SB(L) myself
@floortap - I would have to say no merger. This galaxy has most likely been merged in the past, but it starting to settle down.
No worries 😃
@crazy_hair2000 - yes this would still be considered a spiral. The "gas" on the left are still stars that are part of the galaxy.
Not so sure about merger. Do you have the object ID of the galaxy you think it is merging with - so I can have a closer look?
Not overexposed just viewed in the 'z filter. This would be light that is radiated in the infrared spectrum, objects would look brighter 😃
#bar
Are you using the android app to classify? We finished classifying the hubble images a few weeks ago.
Only ever classify the object directly at the center, it's OK to chat about other objects here, but when classifying - center object only!
It is a galaxy 😃 Looks like it has a bar and spiral features. Not much else you could tell from this image.
That is an optical artifact - it is not real. Looks like a bad column on the CCD camera.
Correct! They are both foreground stars - not connected with the central galaxy 😃
I can see faint spiral features, so I would say no. Have you tried flicking between the default and inverted image? I find it helps!
Try flicking between the inverted and default image - it can make it easier to determine features. I find it helps a lot!
Just try your best - it is your classification we need 😃 I would go with barred spiral, disturbed.
It is definitely a galaxy - it is more obvious when viewing the image in colour 😃
Here you go - link to SkyServer
The bright well defined dots? They are foreground stars from our own galaxy 😃
Looks like something went wrong when theimage got generated #noimage
It is a galaxy - made up of billions of stars - if you scroll down you will see the link to the colour image 😃
I would also go with overlap - no visible interaction.
2/2 ... disturbance or interaction between these galaxies. Most likely an overlap.
1/2 ...You could try looking up the redshift of both galaxies. If they are similar then there is a chance they are interacting. Not much ...
Yes! same galaxy just viewed in a different wavelength!
Nice bar 😃 No, it is not a lensed galaxy - spirals do not usually have the mass to cause gravitational lensing.
#barred #ring
Nice #pseudo-ring
#merger same redshift at z~0.37
It is an artifact - most likely a satellite trail.
Neither 😃 We are only viewing this galaxy in a single band or filter, so it can be difficult to make out features. Bar and spiral for me
Nice #bar ! Very subtle spiral features.
Link here - looking at it - definitely foreground star 😃
Just looking at this image I would say a foreground star or a clump of star formation. Have you had a look at the Skyserver image?
Much the same link here
Just looking at this image I would say bar, resonance or inner ring and a outer psuedo-ring. Let see what it looks like on SkyServer 😃
Went for edge on for this one - On SkyServer it looks like a loose spiral with a halo 😃 Apparently that is a steller nucleus at the center
Spiral features in the inverted image
Looks like we have a bar - that could give the appearance of some disturbance. Nice 3 armed spiral!
Follow the instructions here to see the image on SkyServer 😃
No worries 😃 If you look at the colour image it is a spiral galaxy - but it the black and white images that we are collecting data on.
Sadly not 😃 It is a galaxy viewed in a single wavelength / band so it is quite faint. Just try your best to classify it!
Lovely example of ansae at the ends of a bar! Info here
#barred #spiral #z_band
Just classify the one at the center 😃
It is a spiral galaxy viewed in the 'u band - in these images it can be a bit tricky to make out the features - just do your best 😃
@Danute - can you please clarify why you think the central galaxy is boxy? and also where you are seeing the lens / arc Cheers 😃
Not an irregular galaxy - stunning 2 armed spiral 😃
Not so sure I would go with irregular for this one - the single band images can be a bit misleading.
Looking at the SkyServer image it looks like a foreground star - it doesn't have the colouring of a SN as usually seen in SDSS images 😃
Just try your best - there is no wrong answer 😃 I Would of classified it as a barred galaxy - possible ring.
double nucleus?
I am going to go with #overlap 😃
Not a jet 😃 This looks like one of the old Hubble images - all the objects are galaxies 😃
Not so sure about smooth - can you see the 'tips'of the galaxy going in different directions?
#star_formation 😄
No merger - the bright spot on the right is a foreground star - but what a stunning barred spiral galaxy at the center!
I am not seeing a merger - are you talking about the clump in the lower left of the galaxy? Region of star formation 😃
Hmmm,not so sure I would go with irregular. Nice spiral structure with clumps of star formation.
Cool 😃
Once again - do not be influenced on what you see / expect to see on SkyServer. We want to know what you observe on this image. 😃
Not necessary to tag objects you see on SkyServer - this is a separate survey 😃
What it looks like on SkyServer is not that important - concentrate on the image you get to classify 😃 Thanks!
blog here
Classify the image as you see it in black and white - not what you see in colour (on SkyServer)! There is an important reason why 😃
SkyServer is not always right - it is nice as an additional resource - but it is not infallible:-) Looking at the spectra - same redshift.
Welcome 😃 Everyone is new once - and there is no such thing as a mistake! We all work together in the interests of science 😃
At the center? That is a galaxy 😃 They are rather fainter when only viewed in a single filter - in this case the 'u band
Read the discussion to the right 😃
Not really 😃 Spiral arms can be rather loose. The galaxy does seem to have a bar - nice!
2/2 ...or disk' and 'No, it is not an edge on' you would then get asked if it is a spiral. Hope this helps 😃
1/2 There is no way to redo your classification - but not too worry as it will get classified by others. If you selected 'features...
Classify the image as what you see here - not what you see on SkyServer!
It has a bar and possibly a ring. Start with features or disk and take it from there 😃
I am only seeing 1 spiral galaxy or do you mean the number of arms??
The object to the right is a foreground star.
I would agree with you - there does seem to be a slight bar running right to bottom left.
A foreground star 😃 Flagged as such on SkyServer, also not the distinctive colouring of a SN. Happy Hunting!
I am really enjoying the single band images - and there is an important reason why we are classifying them 😃 More details in the blog.
I don't think it is a merger - we are only viewing these images in a single band or wavelength so that could account for the strangeness.
Pseudo-ring galaxy - http://ned.ipac.caltech.edu/level5/Sept11/Buta/Buta6.html#6.1
In the bottom of the galaxy? A foreground star from our own galaxy.
The image was incorrectly sized - Sorry! Classify as star / artifact and move onto the next one 😃 #imagesizewrong
This galaxy has a lot of active star forming regions - I would not go so far as too say disturbed, early proto spiral perhaps?
I would say it is a single barred spiral galaxy - possible pseudo-ring?
That is one possibility, or it could be spiral arms backing over each other. Looking at the galaxy I think that is more likely.
Really difficult one to make out - even using invert!
A barred spiral galaxy for me, but it is your choice that is important 😃 How did you classify it?
Also, please remember to only ever classify the object directly at the center!
A galaxy with spiral features - try flicking between the default and inverted images when classifying to get a better idea on the shape.
No, foreground star from our own galaxy 😃 Also remember to only classify the central object - this time it is nothing - so star/artifact.
They are dense regions of star formation - young stars are hot and blue - nice!
I am also more inclined to go with #overlap - one of the more stunning ones #zgotw
One of the nicer ones I have go so far. Possible low grade arc and counter. Adding it to the #lens collection for a closer look.
Do not get hung up on redshift or colour. The colour in these is not real, and there is a lot of processing going on.
Once again - not an elliptical galaxy 😃 Too many features - possibly early spiral. Elliptical galaxies are featureless. Thanks!
No! Not an elliptical! Whenever you see any features (such as arms) - classify it as such - not as a smooth galaxy. Thanks 😃
Most likely an unrelated galaxy - difficult to tell - Sorry!
2/2 ... So I would classify it as a galaxy with features and take it from there. Some might say clumpy, but I am not so sure 😃
1/2 Not a relavistic jet - at these distance it would be impossible to see one. It does not have the colouring / intensity of a quasar...
It is a galaxy 😃 We also have regions of star formation embedded within it and the beginnings of a core and spiral arms - Nice!
Sorry - not convinced it is a merger. None of the galaxies are interacting.
Hmmm, not so sure... there is no counter image and not enough arcing for my liking. The blue blob at the bottom is unconnected.
The dark spot is a optical artifact caused by oversaturation. In other words the object was too bright for the camera.
I am really sorry - no arc. Spiral arm.
Is what common? The green and blue splodges in the image, or the galaxy at the center? 😃
Not a smooth galaxy! It is displaying clear spiral features, along with active bands of star formation. Hmmm, colouring is a bit odd.
Still possible to classify - just takes a bit of patience 😃
Yes, it is a distant galaxy, as for the bright center - the galaxy most likely hosts an AGN (Active Galaxy Nuclei) aka a black hole 😃
It certainly looks disturbed! Not so sure about a merger at the center. As mentioned below, could be interaction with the top right galaxy.
Not so sure about bulgeless, but it has been flagged as a possible weak AGN - mentioned in this paper
No supernova 😃 Just a single foreground star that was too bright for the CCD camera - all the odd shapes / colours are optical artifacts.
The green splats are artifacts caused by optical strikes / bad pixels etc... that did not get removed when the images were processed.
Top left? A foreground star from our own galaxy.
Answer below! All the green and blue dots are unremoved artifacts from the imaging process 😃
The three galaxies are unconnected to each other - certainly not a clumpy object 😃 Happy Hunting!
I would go with overlap - no signs of disturbance. Also, the photoZ of the orange elliptical indicate it is a lot futher away.
2/2 impossible to see stars behind galaxies billions of light years away. I would say this galaxy is host to an #AGN.
1/2 This is a galaxy - and no, that is not a star behind 😃 All the stars we see are foreground stars from our own galaxy so it would be ..
I don't think we have any overlapping stars - just one clumpy galaxy 😃
It is an irregular galaxy - nice star formation going on.
Yes, I would classify it as such.
I am really sorry but it is a foreground star - NED confirms.
Not a star - a galaxy 😃 Most likely containing an AGN
I would agree - what a beauty!
Just classify as star / artifact and it will eventually be removed from the dataset.
The brighter blue area in the galaxy are regions of dense star formation - young stars are hot and blue, hence the colour of the galaxy
No interaction - so they are not merging. I would not consider this an overlap as the galaxies would need to be superimposed over each other
I would go with a 2-armed spiral with star formation. No signs of merging - sorry!
They are all artifacts - they follow a broad linear pattern that has only partially been removed.
That is an artifact - most likely an optical strike that has not been removed.
That 'blue' blob is orange in the image in the letter, so not related / a counter image of, the 'arc' at 12. Arclet at 8 more interesting.
At the edge of the image? Unrelated - way outside the Einstein radius.
Not so sure about a bar - but 2 armed spiral sounds good 😃
😃
Hi and welcome @O.B132 😃 Sorry- no lensing - two galaxies (a spiral and a edge on) starting to interact - lovely image!
Without having the adjacent image to look at, one can't say for sure. Takinginto account colour and shape - I would go with another galaxy
Edge of the imaging field - as the images we classify are composites from several different filters the edge can differ from 1 to 1.
Hi @koedooder 😃 Can you leave a bit more info eg. arc / quasar / where in the image. We need this info when we pass info along... Cheers.
I am going to go for no with this one sorry! #no_lens
At the center? Looking at the colour it is way more distant than the blue fluff just below it 😃 Overlap.
This is an almost edge on galaxy with star formation and dust lanes. You can see the spiral arms - stunning!
From this letter: http://iopscience.iop.org/1538-4357/600/2/L155/pdf/17385.web.pdf
Well, it was considered a possible candidate back in 2003 - but the note relating to it is not very convincing "blob + possible cluster" 😃
Hmmm - not enough arcing for my liking - but I will have a closer look.
No - a satellite / companion galaxy to the central one 😃
No - no voorwerp. Sorry!
diffraction spike
No galaxy - the algorithm that chooses the images for us to classify got confused by the diffraction spike from the bright star off screen.
All artifacts - imaging errors that were not removed during the cleanup process.
This is a galaxy - very fuzzy. I would most likely classify it as smooth and inbetween.
Yes - Looks like we all have a #bar and a bulge 😃
An artifact that was not removed from the image. Most likely a particle strike.
The edge-on is not showing any signs of interaction, so I would personally go with overlap.
It is at the edge of the field that was imaged 😃
Not a supernova - most likely a foreground star from our own galaxy 😃
I would say it has spiral features, and go down that classification route 😃
No planets would be visible at these distances 😃
The central object is an elliptical or smooth galaxy, not a star!
Looking at the galaxy the blue arc are more likely star formation than lensing 😃
At the center? It is a smooth inbetween galaxy 😃
As pointed out - not a star. I would go for a round elliptical galaxy (E0) myself 😃
Read below - an artifact caused by over saturation 😃
Broad line refers to the type of emission lines we see in the spectra. I am sure you have asked this / made reference to this before???
For others reading: cosmic ray strikes can present themselves in a straight line.
Just concentrate on the object at the center and try to ignore the artifacts 😃
All the bright red / green / blue spots are optical artifacts - cosmic ray strikes / bad CCD pixels / edge of chip etc.
Looks like a single clumpy galaxy.
Bright spot @10, left spiral arm? Most likely a foreground star. SN tend to be bright blue/green depending on what survey you are viewing.
Most likely star formation - does have the vivid colouring one would expect from a voorwerpje. Sorry!
In a short answer, no. That is why lenses are so important - a lot of a galaxies mass is not visible, so we can only make estimates.
Still only a candidate - can't find much else on it.
Not disturbed - a fuzzy spiral. Not much else we can tell from the image.
Sorry- not gravitational lensing. The arc would have a different colour from the lensing galaxy. Star formation with spiral characteristics.
2/2 is more important when visually indentifying a lens candidate. Followed up by modelling and spectragraph.
1/2 No, not really. It is more the mass of the galaxy and not necessarily the size that determines lensing. Looking at the shape / colour...
@ramberts - kpc (kilo parsec) is a unit of measurement, in this case it is the size / diameter of the galaxy.
I will add it too the #lens collection so I can have a closer look when I have more time. It does look a bit arc like, but I have concerns.
Yup 😃 Always remember to only ever classify the object at the center 😃
They are all imaging artifacts - the colour and shape are a clear give away!
Sadly not 😦 A clumpy galaxy - voorwerps have very vivid colours - usually deep blue / green.
No interaction between the 2 edgeons at the center, so I would go with overlap. Remember to only ever classify the galaxy at the center 😃
A foreground star from our galaxy - did you just get this using your desktop browser? 😃
BTW welcome 😃
Possibly a disk galaxy seen slightly off axis, so instead of viewing it as a edgeon, we get to see spiral features at a small oblique angle.
I am going to go with particle strike - artifact. Sadly not available in 'examine' in the different filters.
No, not a line of stars - a diffraction spike from a star off screen to the left. Unrelated to the galaxy at the center of the image 😃
Not a comet 😃 A edge on galaxy - happy hunting!
Same cluster as AGZ00085fg - GOODS full-depth
Same cluster as AGZ00087r5 - CANDELS 2-epoch
It could be an artifact that has only been partially removed or just noise 😦
A foreground star with diffraction spikes and other artifacts associated with over saturation 😃
There is no way to go back and correct a classification - we want you first impressions! As for a bar, I would of personally said no 😃
Sorry - too diffuse to be lensing, also would expect the shape to be more centred around the galaxy, with the galaxy having a greater mass.
The line? or the blue clumps in the galaxy? The line is a diffraction spike, the blue clumps star formation 😃 Hope this helps!
I would classify it as such as it could also have a dustlane - you also could of gone with smooth cigar shape - really up to you!
Same galaxy as AGZ00082vd
Same galaxy as AGZ00082vj
Awesome diffraction spike from a bright star off screen 😃
Yes, this sometimes happens 😃 An algorithm chooses the images that we classify - It tries it's best, but occasionally gets it wrong!
Difficult to say - hardly any interaction, so I personally would go with no 😃 Hope this helps!
Artifacts 😃 Either particle strikes that have not been removed, bad pixels on the CCD, or less likely - asteroid (due to 'linear' pattern)
See post by @C_cld below - overlap, not a dust lane - Sorry!
Bit concerned about the spiral features on the left and the diffuse nature of the lower arc - but still nice 😃
I agree possible #lens candidate 😃
Yes it does 😃
No - not an irregular galaxy 😃 A barred spiral with star formation
Not lensing - mass of the galaxy is on the light side 😃 Nuclear or inner ring is my guess 😃
Not an artifact - look like a very faint galaxy at the center 😃 The blue dot on the right of the galaxy could be a star or star formation.
...and this object is a galaxy - the pixelation of the image makes it difficult - but just try your best 😃
Just remember - classify the object on what you see - additional information is not necessary when classifying 😃
No lensing - sorry! The blue bits are regions of star formation.
stunning #edgeon
@adithya No. Not an Irregular galaxy. Also this is a retired SDSS image - how did you come about it?
Yes, a local cluster of stars! Sadly it is a SDSS image that has been retired - are you using the app or a normal browser?
Not a lens - too diffuse, no counter image, odd placement. More likely artifact - unable to view the raw data to check.
Only visible in the 'r band - artifact. Sorry!
A very clumpy irregular galaxy - nice!
Regions of star formation in the arms of the galaxy. Still looks quite 'young' and 'wispy' so it is not as well defined as other spirals
It has some of the visual characteristics of an AGN, but without spectra we can't confirm it. #AGNp
SDSS has it classified as a star 😄 http://skyserver.sdss.org/dr8/en/tools/explore/obj.asp?id=1237655369825845645
Faint spiral features in the galaxy, so I would go down that route 😃 Not likely to be a merger as I can't see any signs of interaction
That is the galactic core of the galaxy- sometimes referred to as the 'bulge'. The brightness of this one is causing a few artifacts!
Sadly - all photoZ 😦
Thanks - I guess. I was going to look into it after I had finished dinner. Hence the post 😃 Still a few more questions to answer...
#odd - most likely a star, will look into it later.
Lenticular is another option...
To be honest - there is so much noise in this image, there is not much that you could classify about it - apart from maybe a galaxy 😃
Looks like a spiral arm. Lensed galaxies will always have a different colour from the lens itself, the shape isn't quite right. #no_lens
You can read more in this thread 3.6 relativistic jets in optical and radio by @budgieye!
Sadly not - at the distances we are viewing it is not possible to see relativistic jets - even with the hubble telescope!
Answered on the right...
Cheers Marjie! I had a feeling you felt the same way 😃 I will look into it 😃
Hey Marjie - do you have the link? I know NED can be wrong at times, but this is certainly not a gravitational lens!
Hi everyone 😃 Please remember to only classify the object directly at the center! Not the galaxy to the top left! Thanks 😃
I would go for a clumpy irregular - difficult too tell if it is multiple galaxies. If we knew the redshift we could tell if they are related
Why do you think these are AGN's? Is it just the colour? Or do you have supporting spectra? Just curious and too busy to check 😃
I'm sorry - there is no star in this image! What object were you referring to? At the center we have a smooth / elliptical galaxy 😃
#clumpy
Hi @stuartthomas - do you have a link to the spectra that confirms this as an AGN? There doesn't seem to be anything on NED - thanks! 😃
The green and blue 'confetti'? Those are optical artifacts, they are not real - just caused by imaging and processing.
2/2 at the lower right might be unconnected. Still - there is enough to make it worth another look - Nice! 😃
1/2 The colour looks good for a gravitational #lens - but I am a bit worried about the alignment around the galaxy. Also, the blue blob ...
...and at this resolution we can only make guesses 😃
I would of classified it as such 😃 The colour contrast between the ring and central galaxy is interesting... will look into it a bit more.
wow - #stunning 😃
I am bit undecided about this one - it looks like a merger in the colour image, but have you had a look at the 'i filter on examine ? hmmm
...We can just identify star nurseries 😃 Happy hunting!
@isak.austin - in these images we are unable to see individual stars in galaxies, so we are not able to classify them into categories 😃
The blue streak is another galaxy 😃 No lensing - look for blue / red arcs around a galaxy for lensed galaxies. Hope this helps!
Blueish smudge 2 to 3 - noise or #lens ? No visible counter image, not convinced about by the shape, but it still caught my attention.
#smooth z~0.6
#merger - lovely tidal tail extending between the two!
The central galaxy is not showing any signs of disturbance, difficult to tell... sorry!
A foreground star 😃 The weird colours / shapes are artifacts caused by the light of the star overwhelming the CCD camera on the telescope.
I am also not seeing any signs of merging 😃 lovely dustlane!
Difficult to tell - it could be either. Looking at the shape I would more likely say star, but ultra compact galaxies are similar in shape.
The galaxy looks pretty symmetrical, so I don't think it is interacting. It could just be the inclination that we are viewing it.
The answer must be in one of the papers it is referenced in, but someone will have to have the time to go through them 😃
No, if you read all the comments below this object has been written up in several papers - either a Lyman Break galaxy or a star 😃
3/3 see a zoomed out image to confirm if that is the case! At the moment it is all just guess work 😃
2/3 causing the disturbance is off screen to the right. There does seem to be a faint tidal tail in that direction. We would need to ...
1/3 The bright white bit, is the bar of the disturbed spiral. The orange galaxies are unrelated to the central one. I think the culprit...
Yes - they are all foreground stars 😃
A galaxy 😃 I would select 'Feature or Disk' - 'Clumpy' and take it from there...
I would go for galaxy with spiral features, not so sure about clumpy! There is no wrong answer, so just give it your best shot 😃
Foreground star for me 😃
Most of the redshifts are Photometic - in other words- an estimate. Take all the redshifts with a pinch of salt, and just classify the shape
Having said that colour is subjective - it can change depending on processing of the images and the equipment used.
.. I am sure someone could work it out - I am just at work 😃
The Voorwerp was green in the hubble images with z~0.05 - most of images we are looking at are a lot more distant, so greater redshift...
@budgie another concern it that the 'cusp' does not seem to centered around the point of greatest mass. Hmmmm...
The four upper dots would make up a nice cusp arrangement - but as you said there are similar dots in the image...
or quite possibly a diffraction spike from a foreground star 😃
It is 😃 That is why I love science! Something new everyday! I will try to read the other papers...
Which I have not had time to read - so I do not know what the final consensus was 😃
Yes, @C_cld mentioned it in his original post. The paper is quite old 2007 - I did read it earlier. Another 3 more recent references 😃
This is a foreground star - they look a bit odd in the Hubble images!
#smooth
#irregular
#stunning
When you see a (?) or PHOTO after the redshift value in NED it means it is an estimate 😃 Hope this helps! 😃
I would take the redshift on NED with a pinch of salt - the link posted below has it estimated at 2.59 - looks like both are estimates 😃
Looks like it extends through the whole image, my guess would be a removed artifact. These images are highly processed.
Could be an #overlap - not a lot of disturbance between the galaxies.
#clumpy #irregular
There is no lensing in this image - sorry.
Nice colour, but - the arc follows the pattern of a spiral arm. Most likely to be star formation in a arm.
Hmmmm - more likely to be spiral arms. Nice colour and placement, but I think unlikely.
Cool indeed 😃 Star with background galaxy - one for the art thread 😃
wow - we are truly privileged to see these images 😃
The green blobs look like foreground stars- the colours are a bit different with this survey 😃
Sadly, the object at the the center (which we have to classify) is indeed an artifact. Otherwise I would say galaxy cluster - Nice!
Correct! Artifact on the left of the galaxy 😃
Not so much unusual, rather uncommon:-) A spiral galaxy with multiple undefined arms, that have active star formation regions.
We do! clumpy indeed!
AGN = Active Galaxy Nucleus 😃
A foreground star 😃
2/2 most likely star formation in a spiral arm 😃 The more interesting would be what caused it on one side only 😃
1/2 I think I would of gone with asymmetrical - the two sides of the galaxy do not mimic / weigh each other out 😃 As for the clumps...
SDSS = Sloan Digital Sky Survey - we were classifying that survey up until yesterday 😃 Now we are onto Hubble!
Star formation is my guess - also the galaxy is quite clumpy, so that is another clue.
Diffraction spikes from bright stars off screen 😃
Thought I recognised this one! Discussion on the right 😃
I think the blue objects to the right are foreground stars - remember to only classify the object at the center!
Another difficult one! New surveys are a learning curve for everyone 😃 I would most likely go with irregular other than merger, but... 😃
Good call! 😃
On the left? Yes,a foreground star 😃 Smooth,round galaxy at the center 😃
Wow - difficult to tell! I would most likely also classify it as a merger - but it certainly is clumpy! Irregular is another possibility..
Just star formation - but actually quite interesting...
I would go for 2 😃
That was from @kwillet - the data on NED is not infallible, always use good judgement, and trust your eyes!.
No dust lanes! I would go for spiral with star formation in the arms, more pronounced in the lower half.
"It could be simply trying to fit a photometric redshift to individual clumps in the galaxy and coming up with very different answers"
A new survey. We have blogged and posted about it. Read this
😃 I also saw that the z associated with this galaxy fluctuates from 0.70 to 3.95 in NED - will post when I get a reply!
Sorry - I was responding to another volunteer. The galaxy is interacting with the other galaxy - Nice dustlane!
2/2 ..as this survey is new for all of us, I decided to get a second opinion from @kwillet and 1.12 looks about right 😃
1/2 Oh, you got it from NED! Always map the redshift value to the first match from the table - in this case z=1.12...
I am just having a closer look 😃 My 'hmmmms' means I am thinking and looking!
As for this object...hmmmm...
Most galaxies do have black holes at the center, but we would only see this in the form of AGN's (Active Galaxy Nuclei)
I have answered you in your discussion 😃 Hope it helps!
The blue spots are regions of star formation. In these images the young stars are hot and blue in colour - nothing to do with the lifespan!
You should put that in the art thread 😃
http://talk.galaxyzoo.org/#/boards/BGZ0000002/discussions/DGZ0000vlc
Hi @turelli - where did you find the redshift value? It seems a bit high...
I can't see any dust lanes but it does look very disturbed!
All foreground stars from our own galaxy 😃
It is blue because of all the active star formation - young stars are hot and blue 😃
Not lensing, as it is the same colour as the galaxy 😃
#merger #dustlane
Maybe 😃 It could also be star formation on a spiral arm. Just go with your best guess 😃
Yes - we now now classifying Hubble images 😃
Answer below 😃 It is a satellite trail.
It is right on the edge of a field - http://skyserver.sdss.org/dr8/en/tools/chart/chart.asp?ra=180.37363329&dec=69.3240816
Stunning #merger!
It is a galaxy - I would go with a seriously disturbed spiral. The blueish region at the bottom is star formation. Happy Hunting!
No ring here - this is a single, very disturbed galaxy, with some star formation 😃
An optical artifact caused oversaturation - click on link for more info!
Not colliding 😃 An optical illusion called 'line of sight' makes them look closer to each other than what they are.
😃 The evening observing run was just beginning, hence the light green back ground, the sky was too light!
More often than we would like 😦
Not a merger! The 2 galaxies are at very different distances, so it is by line of sight that they look like they are connected 😃
Nothing 😃 It is from the edge of the survey - classify as a star / #artifact and it will be removed from the classification dataset 😃
There are so many foreground stars in the image, I am more likely to think it is another star. 😃
Looking on NED it is classided as both an irregular and a close compact group - several notes and references 😃
I am sorry, I do not see any spectra associated with this galaxy. Have a read of this post for more info 😃
Definitely a galaxy!
They are certainly not galaxies! I am more inclined to go with foreground stars - but they do have a rather uncanny alignment.
Just classify as a star / #artifact and it will eventually be removed from the dataset. Thanks!
Not a artifact 😃 visible in several filters. I would say they are gravitationally bound galaxies, quite possibly interacting.
At the center or top right?
Hi @tonyg123 😃 It is an artifact - oversaturation - Happy hunting 😃
This is a foreground stars from our own galaxy - click on the link for more info 😃
Here is the zoomed out image - definitely a star: http://skyserver.sdss.org/dr8/en/tools/chart/chart.asp?ra=348.78119554&dec=72.03236077
These are all foreground stars from our own galaxy- read the link for more info 😃
Sometimes it is difficult to tell, but I would classify this one as a galaxy, it is too diffuse to be a star. NED and SIMBAD agree - galaxy.
There certainly seems to have a very slight spiral pattern. I would also add that it looks like a low surface brightness (LSB) galaxy.
The blue lights are regions of intense star formation - nice!
Hi and welcome @Gtar 😃 are you referring to the other round objects in the image? They are all foreground stars from our own galaxy.
The object at the center is a galaxy - I would go with a LSB (low surface brightness) or dwarf galaxy.
Elliptical galaxies do not have bars, they are featureless 😃 lenticular or disk galaxy for me
I would say yes - very fuzzy and faint but certainly visible. Clearer in the inverted image.
You can read more info why here - there are also links to the original thread in the forum 😃
#dwarf #irregular
#IC 0043
I would go with a barred two arm spiral - The arms are very faint.
I would suggest blocking his email address - there is no point having to put up with all that agro 😃
Not too mention the abuse and harassment he caused / is causing.
Sorry you mistook my post for anything other than what it was 😃
Foreground stars 😃
No, it is not an irregular galaxy 😃 I would go with #dwarf or #LSB
These are foreground stars - they look odd because of imaging errors. Read this thread here for more info 😃
No star deaths are involved with galaxy mergers - Galaxies are mostly open space so all systems re-align themselves. Green dot = artifact
The lovely colours are artifacts caused by imaging errors - these objects are most likely foreground stars. 😃
A group or cluster of galaxies that are gravitationally bound -some interaction.
Foreground star - no gravitational lensing- Sorry!
#round_bulge
Galaxy - yes! The odd colouring is an artifact - these images are compressed. Looks better on the SkyServer image!
An overlap - the galaxies are not connected - they are at different distances from us.
Click here - The image is slightly rotated.
Always remember to only classify the object at the center! The other object will get it's own chance to be classified 😃
That is an optical artifact caused by slightly misaligned filters - you can see a similar red dot in all the objects in the image. 😃
3/3 a blue colour are young galaxies with star formation. These galaxies tend to be close to us. Search 'look back time' for more info.
I would also tag it with #LSB (LSB = Low Surface Brightness) and #dwarf 😃
2/3 the distance of the galaxies from us. The blue colour galaxy is a lot closer to us than the central elliptical galaxy. Galaxies with...
1/3 Actually, the blue irregular on the left is not connected with the central galaxy 😃 Looking at the PhotoZ of both we can estimate...
Starformation can also be a normal part of galaxy evolution, totally unconnected with interacting / merging galaxies 😃
I would go with star formation, the pattern clearly follow the pattern of the spiral arms 😃
Not at lot of disturbance, so I am more likely to go with overlap,although it is really difficult to tell with some images 😃
More info on artifacts here
This is a foreground star from our own galaxy - overexposed with filter error. Classify as a star / #artifact 😃
These are all foreground stars from our own galaxy - more info here 😃
It is a foreground star from our own galaxy. Overexposed, with filter and imaging errors. Classify as a star / #artifact 😃
#x-shaped bulge
#AGNp
Only classify the object at the center - all other objects can be ignored. If I classified this image, I would go with star / artifact 😃
All explained in this thead here. A trial, at the moment it will not be expanded to other hashtags.
There is a lot of background noise in this image, have you tried viewing it in the inverse?
No gravitational lensing. A smooth galaxy at the center, surrounded by foreground stars. The green colour is down to filter issues.
I would go with #irregular galaxy 😃 Nice one!
There is no such thing as a incorrect classification, multiple people will classify the image and we go with the mass consensus 😃
Are you talking about the two bright purple objects in the bottom right? Or the purple in the galaxy itself? 😃
And what a stunning one it is! #zgotw
So it is! Classify as a star or #artifact and move on to the next image and thanks for your classifications 😃
Sorry but no gravitational lensing! These are all foreground stars. Happy hunting!
Correct! A foreground star
The colour distortion is not real - these images are made up of multiple different coloured* images and sometimes they get misaligned 😃
The blue area in the galaxy? That is a region of intense star formation. Nice! 😃
I can not see any distortions, so I would be unlikely classify it as a merger myself. Happt hunting!
Not a star! A round elliptical galaxy 😃 Sometimes it is difficult to tell them apart 😃
A foreground star from out own galaxy.Click on the link for more information!
Classify as a star or #artifact - observing / imaging / focusing errors. Most likely foreground stars 😃
The black arc? that looks like an artifact for me. Dust lanes are mostly found in disk or spiral galaxies. This is a lovely elliptical 😃
Hi Rachel, only ever classify the image directly at the center. In this case I am more likely to go with foreground star.
More foreground stars - the lack of focus and strange colours are caused by bad imagining conditions
A foreground star from our own galaxy. The colour is not real, it is what we refer to as a artifact.
They are both stars - classify as a star / #artifact and move onto the next one! Seemy other reply for a link to more info 😃
Both foreground stars - so no merging 😃 The apparent closeness could just be an illusion - line of sight.
A galaxy - the blue clumps are active star formation regions. I would personally go for 'spiral or other features' but it is your choice!
Both the object look like foreground stars - the image is quite out of focus.
No, not a merger 😃 The object in the lower right is a foreground star that is in front of a more distant galaxy.
That so cute 😃 A smiley face 😃
Hmmm, foreground stars for me - so star/artifact would be a good call 😃
An image from the edge of the survey area - Loads of filter / environmental / imaging errors. Classify as star/artifact 😃 Happy Hunting!
Hi and welcome @wtyler - This is a foreground star from our galaxy. The colours are not real - they are artifacts caused by over-saturation.
3/3 ... and you have already created a discussion about it (where you can discuss anything) , so what is the problem? 😃
2/3 Like linking comments directly to a image. We have always maintained that all comments in this section should be related to the image.
1/3 This is not the forum 😃 Talk is the Zooniverses own software, so we can do a lot that could not be done previously...
The comments have always been reserved for the image above. Two years ago there were no moderators on GZ talk, as hardly anyone used it!
The green spot is an artifact - most likely a particle strike.Only visible in the 'r band. They can be easily confused with supernovae!
2/2 The comments below should only be in reference to the image above and not objects out of the field of view. Thanks!
1/2 Hi @AlphaAurigae - unless the object is visible in the image above, can you please refrain from posing a comment about it? 😃
I would classify it as an artifact - it could be a star or a galaxy, but we cannot tell due to the imaging / filter problems. #artifact
The colours are not real - this is a image of a foreground star with loads of filter / imaging errors.
Looks like the filters were slightly misaligned, not redshifted - sorry!
Artifacts of foreground stars - classify as a star / #artifact.
As mentioned in another comment, only classify the object directly at the center 😃
You could classify it as : smooth, round, something odd, other 😃
Always classify the object directly at the center, ignore all other objects. This is an amazing galactic cluster made of dozens of galaxies.
Yes, it is a star 😃 Just classify as a star / #artifact and move onto the next image.
Only visible in the 'r filter so it is most likely an artifact that has not been cleaned up from the image.
#x-shaped #dustlane
Very faint spiral arms and features for me, not so sure about it being disturbed but with images like these it is difficult to say 😃
You could classify it as either a smooth cigar shape galaxy or edge on galaxy. It is your opinion we want after all! Happy Hunting 😃
That is an artifact of a foreground star caused by imaging errors. Classify as a star / #artifact and move onto the next image 😃
Overlap for me - no distortions, sadly, also no spectra.
These are all artifacts of foreground stars. Classify as star / #artifact and move on to the next one 😃
Not a nebula 😃 This is a young star forming galaxy, somewhat irregular in shape.
The object at the center is a star. The galaxy that SkyServer is referencing, is the one to the right. Always recheck the SkyServer results.
I would also say so 😃 Nice!
Read below 😃 Foreground stars from our own galaxy - the milky way.
Only ever classify the one at the center! And, you are right it is a spiral or disk galaxy 😃
The object to the lower left is a foreground star, so no merging n this case!
http://skyserver.sdss.org/dr8/en/tools/chart/chart.asp?ra=78.16399977&dec=27.29404528
The colour is misleading, it looks like they had filter issue when it was imaged. See the link to the zoomed out image in next post 😃
I would go for a disk galaxy - possibly edge-on.
I would be more inclined to go with an irregular galaxy. Very disturbed!
Not an AGN, no spectra. Most likely just a bright core.
Not a lot of disturbance in either galaxy- With no spectra, I am going to say that they are unrelated to each other.
These are all foreground stars from our own galaxy. Have a read of this thread here for more info 😃
I'm sorry, but I am not seeing any spectra that would suggest this is an AGN. Do you have a link? 😃
Hi Ian, no lens. The objects on either side of the galaxy are foreground stars.
Welcome to the zoo! I would go with disk galaxy with a bar.
Sorry 😦 I now have to get back to studying, so I will be scarce for the next few weeks...
The point of GZ is not about making personal discoveries, but rather contributing to the group collective.
To echo C_cld - the further investigation of objects posted on talk is mainly for our own education and to involve a wider community 😃
It is an Artifact 😃
It is an artifact - oversaturation
It is a foreground star from our own galaxy - click on the link for more info 😃
No sign of a voorwerpje - they tend to have a very distinct colouring. Most likely foreground star or satellite galaxy.
Blue dot in the lower left of the galaxy is the target. Interesting...
I would go with a chance alignment 😃
2/2 ..interested in how you view / classify the object. Any info you post from external sources is more for educational purposes.
1/2 If it is on NED or SIMBAD, we can already cross reference it, and it would be quicker to directly query that database. We are more...
Yes, it is an artifact 😃 Looks like foreground stars.
Very Pretty 😃
Looks like a possible AGN #AGNp
Hi Ian, nice #bulgeless edge-on galaxy - nice find! 😃
Oh, you mean the partially removed trail on the right?
2/2 is slightly to the lower right of the center. Classify as star / artifact.
1/2 Remember to only classify the object directly at the center! In this case it is a foreground star. The only galaxy in this image is...
These are all foreground stars from our own galaxy. Click on link for more info 😃
Hi and welcome @melikamp 😃 I am not seeing any satellites in this image. Happy Hunting!
Not a satellite trail 😃 A diffraction spike from a bright star off screen to the upper right.
Still an #overlap. You can see faint dustanes of the disk galaxy crossing the edgeon galaxy just north and south of the core - Nice!
An artifact caused by oversaturation
I also see a slight hint of a dustlane. Nice!
Yes, it is a galaxy 😃 I would go with disk / spiral galaxy with a ring. Looks like a possible a pseudo-ring.
You can use lower case to enter hash tags 😃 We tend to only use upper case for acronyms e.g. AGN or LSB 😃
Please read the comments left by myself and the other moderators WRT your other images classified as voorwerpjes. Thanks! 😃
No, just no.
Look at the other objects in the image - clearly the filters were misaligned.
This image has been looked at by several scientists - the pattern is just a happy coincidence!
I would go with foreground stars 😃
Looking at the SkyServer image it look more like a spiral arm. The colour is also too similar to the lens galaxy. No lens for me 😃
Perhaps Satellite Galaxy of the larger central galaxy, but without knowing the distance of both we can't tell
These are all foreground stars. The coloring and strange shapes is down to optical artifacts.
Looking at this galaxy it look a bit too light weight to have back hole. The lovely intense colouring is down to a lot of star formation.
The object below the galaxy look suspiciously like a foreground star - Skyserver agrees 😃
The QSO is way off screen to the lower left. Can we please just tag objects in the image itself? Thanks!
Why? - it is confirmed as a SN on both NED and SIMBAD. The co-ordinates match the blue spot and it is referenced in several papers.
Yes 😃 The edge-on galaxy does have a stunning dustlane.
A disk galaxy with a bar, spiral features and star formation / star bursts. Somewhat disturbed.
Have a look at the zoomed out SkyServer image - I think you might find these are all foreground stars 😃
The slightly bluer nuclei look like regions of intense star formation. Sadly, no info on NED
This is a galaxy 😃 Quite disturbed with regions of star formation. On SkyServer you can see several other galaxies close by.
These are all foreground stars - no merging going on 😃
Same as AGZ0003bzo
Same as AGZ0003bzm
No gravitational lensing - sorry! These are all foreground stars,a nice chance alignment. Happy hunting!
I would guestimate with 45 degrees off the ecliptic. Interesting green point in the close upper right of the galaxy.
The red area is an artifact -most likely a misalignment of filters. You can see a similar effect in the top left galaxy.
That is certainly an #irregular galaxy! Interesting 😃
This is a foreground star- classify as a star / #artifact and move on to the next image 😃
More info in this thread here
Classify as a star / #artifact 😃 This is a foreground star - the weird colours are artifacts caused by imaging / filter errors 😃
No worries! It is our fault for having no hashtag guidelines!
The tags arc or lens are usually reserved for gravitational lensing 😃 Will add it to the glossary to prevent further confusion. Thanks!
A lovely galaxy with spiral features 😃 No sign of gravitational lensing - arcs will have a very different colour from the lens galaxy.
The orange object above the galactic core is a foreground star 😃
Classify as a star / #artifact - loads of imaging / filter errors.
Nice #overlap with a edge-on galaxy on the center right. As for the galaxy at the centre a disk or lenticular galaxy.
It is a galaxy - I would go with Dwarf or LSB (Low Surface Brightness) galaxy. Nice star formation regions!
I would go with merger 😃 Pity there is no spectra available - fascinating galactic core.
They are images from the edge of the survey area - classify as star / #artifact and they will eventually be removed from the dataset 😃
It is a foreground star 😃 not connected with the galaxy in the background. Looks like we have a #overlap at 1
This is an excellent guide on redshift colours : http://talk.galaxyzoo.org/#/boards/BGZ0000007/discussions/DGZ0000ulp?page=2
A foreground star - the colours are not real due to filter / imaging errors. Classify as star / #artifact and move onto the next one 😃
Those beams are diffractions spikes from a bright foreground star just off screen to the left 😃
I would go for a slightly denser region of star formation. Bit clearer on the SkyServer image.
Just looking at the image, I would personally go with overlap, not a lot distortion 😃
That is only for ZOAG galaxies. For the majority of galaxies it is due to the higher redshift. The further a galaxy is the redder it is.
Agree with Budgie - foreground star. Our eyes are better than an algorithm, and that is why we are classifying these images! 😃
The green dot is an artifact, most likely a particle strike that has not been removed. Only visible in the 'r filter. Nice smooth galaxy.
Nothing 😃 Just classify as a star / #artifact. This image is at the edge of the survey area so we tend to get some interesting artifacts!
A foreground star - the colours are not real due to imaging / filter errors. Classify as a star / #artifact and move onto the next one 😃
Not a nebula, possibly a satellite galaxy, but the image is really too fuzzy to tell. The orange objects are foreground stars.
For it to be considered an overlap, the galaxies need to be superimposed over each other, even if it is only slightly.
In images like this just do the best you can! Even just classifying it as a spiral or disk galaxy is a big help 😃
Only visible in the 'i filter - so it is safe to say it is an artifact.
The central objects are two interconnected galaxies - described in several papers. The blue object in the top right is a foreground star.
Where do you see the lens, so I can have a closer look? 😃
Wrong colour for a voorwerpje -It looks like the red and green filters are slightly misaligned. Spectra classes it as an AGN.
😃 These are foreground stars, so they only look connected due to line of sight. Happy hunting!
Not a voorwerpje 😃 The blue area is a region of star formation. Low Surface Brighness or Dwarf galaxy. #lsb #dwarf
To the right of the galaxy? Yes, I would go for star. Remember to only classify the central object!
That is a stunning one! Stunning #bar and #ring. #ZGOTW for me!
Spiral arms folding back on themselves giving the appearance of a ring 😃
A nice cluster of galaxies 😃 Sorry, no gravitational lensing for me.
Foreground stars from our own galaxy 😃
I think @wtaskew means is that he got this image to classify 2 years ago.... 😉
Imaging and filter artifacts - these are all foreground stars. Classify as star / #artifact and they will be eventually retired 😃
Sorry - no voorwerpje, star formation. Voorwerpjes have a very distinct colouring in the SDSS images.
Here you go: http://www.galaxyzooforum.org/index.php?topic=10635.0
It looks like a pseudoring galaxy for me 😃 I will see if I can find the link to the old thread on the forum.
The smudge down in the 7 position from the galaxy? I would go with overlap-not enough curvature forme 😃
foreground stars 😃 The colour and fuzzyness is down too imaging errors.
The red dot? I think it is a local star, but there is a lot of background noise in the image.
The red stars are part of our galaxy - the blue is more difficult, most likely star formation in the more distant galaxy.
Between what? 😃
Foreground star for me.
Edge-on galaxy with a fore ground star in the lower right 😃
No merging for me 😃 Nice overlap!
Most certainly a merger! Nice 😃
Just got this one - I agree - the 'asteroid' is odd. There does seem to be a subtle change of direction? Hopefully @c_cld will have a look
I would not tag it as boxy as it has no bulge! We use the boxy hashtag to describe the shape of the bulge 😃
It is an image close to the edge of the survey area - classify as a star / #artifact and move onto the next one 😃
More help can also be found in this thread here and here - happy hunting!
It is a local star - read the comments below 😃
Not a merger - I am more inclined to go with a #barred lenticular / Disk galaxy 😃
It does not have the distinct colouring of a voorwerpje, too similar to the colour of the galaxy. I would go with satellite galaxy 😃
right close to the galaxy core? or about a quarter way up the image? or at the edge of the image? 😃
I am really not seeing any voorwerpjies? Where exactly are you seeing them, so I can have a closer look? 😃
Looks like a LSB (Low Surface Brightness) galaxy - nice find! 😃
Really difficult to tell, could also be a dust lane in a lenticular (or disk) galaxy. Have a look at Skyserver image - galaxy cluster 😃
2/2 Having said that it is interesting enough for me to add to the #lens collection 😃 Nice one!
1/2 I was initially going with ring, but it does have nice colouring - an orange smooth galaxy and a blue ring. Wish the image was clearer!
2/2 but that do not have any supporting evidence such as spectra. The p stand for possible, this way we can keep the categories separate.
1/2 It was not tagged as an AGN 😃 It was tagged as an AGNp. We have introduced a new tag for objects that users think might be an AGN...
@Sundog1a - why don't you have a read of the this AGN for beginners, it is part of th user guides 😃
What objects are you referring too? I am seeing no signs of any voorwepjes! Sorry 😃
#lens
No gravitational lensing - we have spiral features and regions of intense starformation.
No,not a lens 😃 Both the objects are edge-on galaxies. Stunning accidental alignment.
Has a nice #bar as well!
Looking at the SkyServer image I would personally go with foreground stars - not galaxies 😃
I would go with spiral galaxy - difficult to tell if it is barred from this angel. Also seem to see some dust. Good to see you Marjie 😃
Foreground stars! If you look at the widescreen image you can see we are in the middle of a star field 😃
The two galaxies are certainly interacting with each other 😃 Nice!
The difference in colour is due to two of the filters being slightly misaligned. More info on artifacts here
Not a voorwerpje - slightly misstacked filters are causing the difference in colour between the two sides of the galaxy.
That is a stunning one! and welcome to the zoo @nhanimator 😃
star formation in an irregular galaxy, no signs of a voorwerpje - sorry!
Just classify as a star / #artifact and they will eventually get removed from the dataset.
?
I think the galaxy at the center is much more distant than the other two, so no interaction / merging for me 😃
Where? No signs for me 😃 Perhaps you should clarify you posts more in future ? 😃
They are foreground stars. The overall green colour is down to filter / imaging errors.
It is just really confusing to classifiers to have images from different surveys (and wavelengths) all posted together!
AA - we have not classified UKIDSS images for a year and we have new images coming up, so perhaps we should concentrate on them? 😃
Spiral galaxy - certainly not a lenticular! 😃
An artifact caused by oversaturation - look on the right for more info. Happy Hunting!
Top right? A foreground star 😃
me too 😃
No, not an irregular 😃 Irregular galaxies are blue and well, irregular! This looks like disk galaxy, almost edge on.
Not likely- sorry 😃 Just a lot of artifacts.
No overlapping 😃 I would go for a barred ring galaxy. Nice 😃
No gravitational lensing 😃 Just spiral arms that have formed a ring 😃
A star from our galaxy. The colour is an artifact from filter / processing errors. Classify as a star / artifact 😃
2/2 enough to be an irregular 😃 I would go with a multi-armed spiral viewed at a somewhat odd angle 😃
1/2 Hi and welcome @spceodity 😃 Excellent guess - this spiral does have more star formation than normal, but it is not irregular...
I would go with star 😃 Looking at SkyServer it appears to be in the middle of a star field!
They are all foreground stars - the algorithm that chooses the objects for us to classify, though it was a galaxy 😃
Pas une galaxie, les étoiles de premier plan - aucune fusion passe. *google translate at work
The galaxies on the left are certainly merging! Not so sure about the galaxy at the center, no major distortions.
I would go with a barred spiral galaxy. The blue colour is due to star formation:-) Could also be called a proto-spiral.
North of the galaxy? Voorwerps have a very vivid colour - I would go with satellite galaxy 😃
Looking at the zoomed out image I would agree - all the objects are out of focus, and it looks like a dense star field.
The bright object on the left is a foreground star, and the central object (that you should classify!) is a galaxy 😃
@liometopum - don't forgot the photoZ is just an estimate and it is advised that you take the error margins into account.
No gravitational lensing 😃 Looks like 2 galaxies merging - Nice!
2/2 triggered by interaction. Have a look here
1/2 Certainly a merger between 2 galaxies - the 2nd galaxy is off screen to the bottom. The blue bits are regions of star formation...
Dense star formation close to the core of the galaxy, if you look at it in the different filter it is not a prefect ring, spiral features?
These are all foreground stars - the odd colours / shape are all artifacts caused by filter / imaging errors.
It is all in the #how_to threads 😃
AGNp - stands for a possible AGN, that does not have any supporting spectra, therefore it cannot be tagged as an AGN 😃
Looking at the colour, this is a young galaxy - old galaxies have a red colour due to a lack of star formation.
I am not seeing any signs of lensing - what object are you referring to?
possibly this mission XMM? Not much info on NED and this is the first time I have come across it.
I am sorry 😃 but I do not see any signs of a nebula in this image. What object are you referring to?
Not an AGN - no spectra and the object to the right is a foreground star, no no overlap either 😃
We use the term overlap to refer to galaxy / galaxy overlaps - not stars 😃
I would go with smooth - round 😃
No merging for me! #overlap
Not an irregular galaxy 😃 Nice ring and bar.
Not an irregular galaxy - I would go with proto spiral. Nice star formation.
Not an AGN - no spectra, slight misalignment of filters, that is causing all to objects to have a red orb on the right.
No nebulas - the discolouration is most likely due to star formation in the spiral arms.
or you could just call it miss-aligned filters 😃
Is it just me or could this also be an overlap? Nice irregular in the front and perhaps a smaller loose spiral behind?
Not magic - an amazing barred 2 armed spiral 😃
Not magic 😃 Just bad filters. All the objects are foreground stars.
A image from the edge of the survey area 😃 Classify as a star / #artifact and move on to the next one:-)
All the objects in this image are foreground stars 😃
Pleasure 😃
A foreground star
1' below the bright one
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=18.32208446&dec=23.26652521
3/3 Because they are in different fields we can have artifacts that would only be visible to images within this field. Hope this helps!
No, supernovas have a very distinct colour and are very well defined. This would be a foreground star from our own galaxy. Happy Hunting 😃
2/3 but fainter artifact just below this one. Both spatially relate to 2 stars that happen to be imaged in a different field on the left.
1/3 I think they are in fact diffraction spikes from a star off screen to the left. If you look at the widescreen image there is a similar..
Please don't call it SS 😃 It is SkyServer 😃 I will have a look...
Classify as a star / #artifact and move onto the next image. This is an image from the edge of the survey area - an artifact 😃
That is an artifact caused by oversaturation 😃 Happy hunting!
Classify as a star / #artifact and move onto the next image:-)
Yes!
@Els Jinx 😃
I wish - then I would be very rich! Image at the edge of the survey area, classify as star / #artifact 😃
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=350.42525107&dec=72.19054105
Problems with the green filter - see the zoomed out image from skyserver, all the objects in the field has the same hue. Link in next post.
These are actually all foreground stars 😃 The colours are artifacts. Classify as star / #artifact
nice #bar
Close! This is a satellite trail - more info in the Artifact thread here
These are all foreground stars, looks like we are in the middle of a star cluster! 😃
Looking at the SkyServer widescreen image there are several similar objects close by, also nothing on NED, both things suggest star.
These are all foreground stars - the weird colours are down to filter / imaging errors. Classify as star / #artifact 😃
I am thinking perhaps it was an artifact that was removed during processing - it extends through the whole image (square root on examine)
Not so sure it is a merger - on first glance I would of gone for overlap 😃
Why? No spectra and it does not look like a particulary promising candidate?
Just classify them as a star / #artifact and move onto the next image. 😃 They will eventually be removed from the dataset.
#abell 0313 galaxy cluster
Hi @julieharkin 😃 That is a diffraction spike from a really bright local star just off screen 😃
It is a satellite trail 😃
This is an image from the edge of the survey are, just classify as star / #artifact and move on to the next image 😃
I am not so sure it is merger, the object on the right looks suspiciously like a foreground star.
The green object is only visible in the 'r band so it is an artifact. The other object is a foreground star.
No spectra - so it is not possible to confirm it as having an AGN. Nice bright core though.
star / #artifact
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=6.3832813&dec=23.58738258
Galaxxies 😃 If you zoom out on SkyServer you can see it is a galaxy cluster, see link in next post,
Classify as star # artifact - loads of filter errors.
I would go with spiral galaxy myself, as a complete ring has not formed and it is slightly disturbed a the top 😃
Just give it your best shot! 😃
Not a nebula, SkyServer has it listed as a star.
No, that is not a AGN. Just a fuzzy spiral galaxy.
DMS stands for Deep Multicolor Survey. It is just another identification that can be allocacted to galaxies / QSO's.
I would say it is a galaxy - the image is just quite fuzzy.
Definatly a galaxy, but the colours do look slightly misstacked 😃
Sorry - no signs of being an AGN.
No interaction for me 😃 The orange object on the right of the galaxy is a foreground star 😃
Not an AGN - please check your PM's. Thanks 😃
Not an elliptical for me - perhaps a lenticular S0 galaxy?
The lowest object is a galaxy, the others are stars. Due to focusing/ filter errors they all have the colouration. Classify as star/artifact
This is a foreground star , not a AGN 😃
Also,it does not display any of the features we would expect to see in galaxies that harbour an AGN.
Not an AGN - no spectra 😃
No AGN, no interaction.
It is an artifact - only visible in the 'i band
http://skyservice.pha.jhu.edu/DR8/ImgCutout/getjpeg.aspx?ra=240.53659093&dec=15.88817671&scale=0.79224&width=512&height=512&opt=&query=
Definitely not a merger! #overlap for me 😃 The edge does not look connected to the awesome galaxy cluster seen in the zoomed out image.
Sometimes the algorithm that selects the images for us to classify gets confused by bright objects 😃 I agree with star...
Not an irregular galaxy - this one has spiral features, so perhaps a proto spiral?
I would go with #overlap 😃 There are no distortions in either galaxy. Looking at the color / photoZ the galaxies are far apart.
No, this is a galaxy- somewhat disturbed with spiral features. The bright blue bits are regions of dense star formation. Nice! 😃
star / #artifact 😃
All the weird colours are artifacts caused by over saturation - no solar flares - just imaging errors 😃
You don't get bars in elliptical / smooth galaxies, so this would be a lenticular or disk galaxy.
Welcome to the Zoo!😃 I would be more inclined to go with a very loose spiral with no bar - but that is just my opinion. Happy Hunting!
Are you talking about the white object below right of the galaxy? That is a foreground star - no merging 😃
Not an AGN - and no signs of interaction between the galaxies for me 😃
More likely it is just a coincidence caused by line of sight 😃
This is a smooth or elliptical galaxy - not an AGN - Sorry!
Looking at SkyServer it is an image from the edge of the survey area, so lets mark it as an #artifact 😃
It is an image from the edge of the survey area- that is why is has a green background. An artifact. Happy hunting!
2/2 I would say this galaxy has spiral features with star formation. Hope this helps! 😃
1/2 Sadly not 😃 Irregular Galaxies tend to be predominantly blue with intense star formation and a very irregular in shape.
It is still quite a interesting colour 😃
To the top right of the galaxy? More likely foreground stars - I would of expected the colour to be more vivid if it was a voorwerpje 😃
You first guess is correct! Three stars 😃
This is not an irregular galaxy - it is a spiral. Irregular galaxies are usually blue in colour with active starformation regions 😃
I have seen similar images and they turned out to be diffraction spikes. Really pretty 😃
NED is not always right 😃 I am more likely to go with an active star forming region, we seem to have a fainter area on other side of core.
A foreground star from our own galaxy. Sadly there were a lot of filter issues when this was imaged. Classify as star / artifact.
It doesn't have the colour we would expect for a SN in the SDSS images. I would wait for @c_cld to give it a look 😃
Hi 😃 Only ever classify the object directly at the center - ignore all other objects. Happy hunting!
Here you go: 3.6 relativistic jets in optical and radio by @budgieye!
Very unlikely 😃 As far as I am aware there is only 1 that we can see in the SDSS images - I will see if I can find the link to the thread!
Hi and welcome @ecary - this is a bad image from the edge of the survey area! Just classify as a star / #artifact 😃
2/2 You could also flag it as a possible merger, as the galaxies certainly appear to be interacting - but it is really your choice 😃
1/2 Remember to only classify the object directly at the center - in this case it is lower edge on galaxy with the dust lane.
Could be 😃 Difficult to tell with no redshift. They could also be galaxies that are in the same group but not interacting with each other.
Hi and welcome @TeresaFearn - it takes a while before the results get released. How did you classify it? Also - there is no wrong answer 😃
I don't think it is merger - the galaxies are not very disturbed. I would more likely say overlap 😃
2/2 left of the galaxy looks unrelated. I would of gone for features, not a spiral / edge on - but that is just my personal opinion.
1/2 This image is incredibly fuzzy so it is not proving very easy for me either. I would not go for merger as the orange object in the top
WOW 😄 That is a beauty!
Not so sure about boxy - I would of classified the bulge as round. Then again, I am not always right! Other opinions?
Hi and welcome @mika75 - that is a star from our own galaxy. It is from the edge of the survey area, so the colours are all artifacts.
and NED would be correct!
Hi @ionutab 😃 These are all foreground stars - happy hunting!
The other objects in the FOV are foreground stars, or are you talking about the smudge on the left of the galaxy?
No, not a merger 😃 These are all foreground stars
Possible polar ring for me too!
This is a foreground star from our own galaxy. The weird colour are artifcts caused by filter issues..
The blue spot is a star from our own galaxy 😃
These are stars - the weird colors are down to filter errors. More info here
I would go with artifact 😃
on the right? That is also a foreground star 😃
'viking helmet' - I like it 😃
Foreground star superimposed over a galaxy 😃 No merging here!
very odd.
With the amount of distortion in the 'arms' I would of expected a second core to be visible if it were a late stage merger.
Certainly look disturbed. The culprit is not visible in SkyServer. Hmmmmm.
Nothing wrong with pink! 😃
Nothing on NED / SIMBAD - so I will go with my initial guess - star!
Not so sure it is a merger 😃 The pink blob is most likely a foreground star, but I will have a look into it.
The orange object below the galaxy to the right? That is a foreground star 😃 Also remember to only classify the central object!
We are all rookies once 😃
Sadly not 😃 The colours in the galaxy are an artifact, perhaps the filters were slightly misstacked?
No arcing or dust lane 😃 It is just a very fuzzy spiral galaxy.
It is an artifact. Something went horrible wrong with the filters/ focusing when this image was was captured 😃
That looks like a much more distant galaxy that is being overlapped by the central galaxy.
Looking at the colour I would say they are a fair distance apart. Two separate overlapping galaxies for me.
Wow - very similar to 'The Swan' http://talk.galaxyzoo.org/#/boards/BGZ0000004/discussions/DGZ10067u9
It is an image from the edge of the survey area - the greeness is all down to filter errors 😃 Classify as star / artifact
Certainly a double! I am just wondering whether the third nuclei in the centre is in fact a star. Similar objects in FOV. No spectra 😦
Certainly a possibility, but we would need the actual redshift values for both galaxies to know for sure.
They are all foreground stars 😃 Also, remember too only to ever classify the object directly in the center! This time star / artifact
When taking the error margins into account, the PhotoZ is quite similar, I wouldn't be so quick to dismiss it as being an overlap.
The blue object? That's a foreground star 😃
Star formation at the tips of the arms 😃
I assume you are speaking of the central galaxy? Not a lens 😃 Those are the arms of a spiral galaxy.
Only visible in the 'r band / filter. So I would say yes, artifact 😃
I would go with just edge-on 😃 You would not see a bar from this angle.
Only ever classify the object directly at the center 😃 That is the rule irrespective of whether there is a star in the image 😃
oversaturation
repost of hubble image: http://www.spacetelescope.org/images/heic0810ax/ (thx @klmasters)
A tidal tail - late stage merge of 2 galaxies 😃 You can find more info in the comments below 😃
Not a voorwerpje 😃 A LSB / dwarf galaxy with some starformation. The orange objects are foreground stars.
Hi @Dippo - just look for dust trails in the normal image 😃
I would say it looks like it! Nice 😃
Hi @RG85 😃 We are all new at this once! Happy hunting 😃
They are all foreground stars 😃 Have a read of this here
Another galaxy 😃 Remember to only classify the object in the center of the image!
I am going to go with #overlap for this one. Can't see much disturbance. Sadly no spectra. PhotoZ error margins quite high.
Every image gets seen and classified by multiple users 😃
Only ever classify the central object - in this case it is a foreground star 😃 Happy hunting!
Another galaxy:-) There is not much more info available,but unlikely to be connected to the central galaxy.
Taking the rest of the image into account, I think background noise is the most likely culprit 😦
Foreground stars 😃 They look really weird due to filter / focussing problems with the telescope.
Wow! Congrats!
Hi brissels 😃 Where about do you see the satellite? The green smudge to the left of the galaxy core?
Over saturation for me 😃
That is a galaxy made up of billions of stars 😃
The orange object at the center is a galaxy, the other objects are foreground stars 😃
The large blue object is a star 😃 the object at the center is in fact the orange object to the left.
Just a foreground star - the weird colour and lack of focus were caused by filter errors. More info here
That is the core of the galaxy 😃 No spectra, but wouldn't be surprised if it was a AGN.
Yes 😃 The bright blue bits are areas of dense star formation. BTW welcome to GZ 😃
No spectra, but I am more inclined to say foreground star.
@nickdwyer53 have you seen my response 5 minutes ago? Classify as star/artifact and it will eventually be removed.
Not a dust lane or ring - It is a bit easier to make out the spiral arms in the inverted image. A bit disturbed.
If you classify them as a star / #artifact they will eventually be removed from the dataset.
Intermediate Galaxy Morphology
Basic galaxy morphology
Elliptical galaxies do not have bars, so this would be a lenticular or disk galaxy 😃
Although the central galaxy is part of a cluster (see Skyserver) - the edge-on looks unconnected.
I have replied to you on the right -->
I would go with #irregular galaxy with clumps of star formation 😃
This is not a merger or a lens (#no_lens) - it is just several unconnected objects that happen to share the same field of view 😃
Just classify as star / #artifact and they will eventually get removed from the dataset 😃
Hi and welcome @SarahSt - these objects are foreground stars, the weird color are down to filter errors. You will come across a lot of them!
It is a foreground star 😃 As are all the object in the FOV
Where about? On the left? 😃
hmmm, Did you just get this one to classify?
I would say over saturation is more likely the culprit and not the misalignment of filters, as the galaxy looks nicely aligned 😃
It certainly has the features of a bar - nice find! #bar There also might also be a few foreground stars directly in front of the galaxy
pseudo ring?
Where about are you seeing the lens? Is it the red line on the right of the galaxy?
In this case I would say they are all foreground stars 😃
I would also classify it as a ring, not a spiral 😃 Nice one!
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=157.05002963&dec=6.29898237
That line is a diffraction spike from a bright star off screen 😃 See linkin the next comment for a zoomed out view.
Nice one! one for the #alphabet collection 😃
Read this thread here for more info on the different type of artifacts you could come across. Happy hunting!
Actually the other way around 😃 The filters have messed up the stars! It is not abnormal to have these problems on the edge of the survey.
no worries 😃
or you could just look left, and click on the 'Orion Nebula thread' 😃
It is part of a #nebula - a link to a zoomed out image is coming up 😃
I would agree, there are certainly spiral features:-)
Even if there is more than 1 galaxy in the image - only ever classify the object at the center 😃 Thanks!
This is an #artifact from the edge of the survey area 😃
I can see the core or hub of the galaxy.Perhaps it is because the arms are very loose?
Not an irregular galaxy 😃 as @ElisabethB said a spiral galaxy 😃
In these images voorwerpjes are usually blue or green in colour 😃 Nice merger!
Only classify the object at the center - in this case the almost edge on galaxy. The bright object on the left is a foreground star:-)
Hey Leonie 😃 do you need any help?
Not a star - a galaxy 😃
What an interesting galaxy 😃 possible bar? http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=44.45586424&dec=-2.32850145
Firstly - only classify the object at the center. Ignore all the foreground stars. I would go with a smooth round galaxy 😃
a foreground star 😃 Have a read of this thread here
I do not think the red objects are interacting with the galaxy. There is a lot of background noise,but my gut instinct says stars.
Filter and focusing problems - I would say they are most likely foreground stars.
No interaction - I would say it is a chance alignment.
I would go with merger 😃 See how disturbed the spiral is?
This is a difficult one - not a edge on, no bulge, it does display some spiral features and the foreground star does not help. Hmmmmm
I will go with foreground stars 😃 Also, it looks like we had some focusing issues 😃
Star! 😃
Yes 😃 It is an #artifact. Imaging and filter errors are to blame!
A foreground star - classify as star/#artifact. More info in this thread here
They are foreground stars from our own galaxy 😃 Looks like there were focusing issues with the telescope.
Only classify the object in the center - in this case the smooth galaxy. You could flag it as being 'Odd / Merger' - but that is just me 😃
Peas tend to be very compact and dense - more so than this galaxy. There is loads of info on the Forum, you should start there 😃
SIMBAD says it is a possible AGN. I am more likely to go with that, than a pea galaxy 😃
Awesome 😃 A #satellite trail!
A nice cluster of galaxies - they look like they are gravitational bound rather than merging 😃
star formation?
These are all foreground stars 😃
Filter problems! Looks like there was an issue with the red filter. Zoomed out image here (click 'get image')
Not a nebula 😃 A galaxy with loads of star formation and very high HI emissions. Have a read of the comments below 😃 Also a #dustlane !
Only classify the object at the center. In this case a spiral galaxy with a slight bar. The orange objects are foreground stars.
Close! They are all foreground stars from our own galaxy 😃
This is a galaxy 😃 The dark spot is a artifact caused by over saturation (aka over exposure). also has hints of a bar!
It is a dwarf galaxy - the blue blobs are regions of intense star formation, otherwise known as starbursts. High HI galaxy
Hi @SeanD82 😃 Only ever classify the object directly in the center. The object on the left is a foreground star - hope this helps!
I would personally go with #merger 😃
Only in the 'r band - artifact.
Only ever classify the object at the center - in this case it is a galaxy 😃 Nice cluster - have a look on SkyServer!
They are slightly misaligned - but you should still be able to classify it 😃
I'm sorry - I do not see an asteroid in this image. As you referring to the skyserver image perhaps?
Personally, I would go for galaxy. The edges are not as clearly defined as those I would expect in a star.
I think you would be right 😃
The central object is a galaxy 😃
Too blurry to tell, but satellite galaxy would be a good guess 😃
3/3 If you look at other official collections you will see other 'originators'. Same will happen if you create a hashtag collection 😃
2/3 Whenever an image gets tagged with the specific hashtag (in this case 'nebula') it gets automatically added to the collection
1/3 It is not my collection - I just created the criteria for the official GZ Nebula hash tag collection 😃 I have no collections.
Sorry no, once you have classified an object that's it - no going back 😃
That is still a galaxy- I can see a slight spiral pattern and areas of star formation. Fairly non-descript 😃
I know they can be frustrating! Classify as star / #artifact and they will be eventually removed from the dataset 😃
There is another larger galaxy to the left 😃 Click here for the zoomed out image.
It is a single galaxy - the filters are misaligned 😃 have a look here - you may have to click 'get image'.
On the left we have an #asteroid and on the right a partially removed satellite trail 😃
Classify as a star / #artifact - there were loads of filter / imaging errors when this was taken. Sorry 😃
I think I would go with #overlap for this one 😃
psuedo-ring?
It is a foreground star 😃 The weird colours are artifacts caused by focusing / imaging errors.
Wrong colour for a voorwerpje - they tend to be blue/green 😃 Looking at SkyServer I would say artifact.
If you have a look on SkyServer, it is part of a cluster - nice!
I would also go with edge-on - really bright core - possible AGN?
Yes 😃 In these images blue = star formation, and this galaxy looks like it has a lot of star formation going on.
and I prefer to use my username... just saying 😃
Ooops - a glitch in the matrix - I was actually posting to this image AGZ0003mxc
The dot at the center is an artifact-over saturation. 😃
Background noise - artifacts 😃
All foreground stars - the weird colours are imaging errors 😃 #artifact
In this case it is definitely a artifact 😃
Yes 😃 #artifact
That is a diffraction spike from a bright star off screen 😃
Classify as star / #artifact - there were filter problems when this image was taken.
Nice starformation 😃
These are all foreground stars - the weird colour are down to filter / imaging errors. Classify as a star / #artifact
Yes 😃 that dark spot is an artifact caused by over saturation (i.e the brightness caused a problem with the ccd)
The big green object along with all the other objects are foreground stars 😃
#no_lens the discolouration is an artifact - other objects in the region have similar colour distortions 😃
They are both stars 😃
That is a tidal tail 😃 the galaxies are interacting and starting to merge - Nice!
The orange object is indeed a foreground star 😃
Sorry - No galaxies, they are all stars.
They are all foreground stars - the weird colors and shapes are down to filter and imaging errors #artifact
and a gorgeous dust lane 😃 Wish I got these ones to classify!
It is a satellite trail - awesome 😃 More info here
Looks like a bar in a disk or lenticular galaxy 😃
They are all foreground stars, the filters were misaligned when they were imaged, so they are very distorted. Classify as star/ #artifact
No lensing 😦 Just slightly misaligned filters. Have a look here for lens targets
Not an irregular galaxy - a smooth or elliptical galaxy 😃
#artifact - see budgies comment on the right.
Looks like an elliptical galaxy for me, but each to there own 😃
Problems with the green filter #aartifact
Stars from our galaxy -more info on artifacts here
Not a nebula - foreground stars with loads of imaging / filter errors 😃
The bright white objects on either side of the galaxy?
Those are actually foreground stars from our own galaxy - the weird colours are artifacts 😃 More info here
It does seem to have some spiral features - just classify it as you see it 😃 There is no wrong answer.
Your first guess was correct 😃 The other figures are stars from our own galaxy 😃
Apart from the almost edge on galaxy at the center, the other objects are foreground stars 😃
Read below - it is a star 😃 The weird colour are artifacts cuse by filter / imaging problems 😃 #artifact
It is an image from the edge of the survey area - just classify as a star / #artifact 😃
Imaging / processing error - classify as a star / #artifact 😃 They do eventually get removed from the dataset.
The red object is a foreground star in our own galaxy 😃
The filters were outof alignment when this object was image - just classify as star/artifact in future 😃
Difficult to say - I am not seeing a lot of interaction. My gut instinct says no.
I agree - foreground stars 😃
No lensing 😃 Starformation in a irregular galaxy.
It is a merger for me - the green dot looks more like a starburst than a nuclei, having said that there is something odd about it...
The green bits are also regions of intense star formation 😃
Not an irregular galaxy 😃 Barred two arm spiral - irregular galaxies will show no signs of having a spiral pattern.
Not a problem! It happens to all of us from time to time 😃
Not a nebula, an artifact. There is a very bright star off screen to the left.
[2/2] Also, irregular galaxies tend to be blue (due to the starformation) and are quite chaotic in appearance 😃 Hope this helps!
[1/2] Sorry - but I would not call this an irregular galaxy 😃 We can see a spiral structure, and it is fairly symmetrical.
That is a stunning one! #zgotw
I personally do not think they are interacting, so no merger fusing for me 😃
Stars have more clearly defined edges, galaxies are more diffused. The colour can also play a role in differentiating the two 😃
The green line is a satellite trail 😃 They move so fast they only get captured in a single filter. They can be green , red or blue.
Foreground stars - the colours are artifacts caused by imaging / filter errors 😃 #artifact
So there is no confusion - lenticular galaxies can also be called disk galaxies - read this here
I personally would go with a separate arm. As for the white dot SkyServer has it tagged as a star and I agree 😃
Most likely stars from our own galaxy - filter / focusing errors 😃 #artifact
A foreground star - the weird colours and lack of focus is due to imaging errors 😃 #artifact
Yes 😃 the brightness of the foreground stars cause problems with the imaging. Have a read here
Only visible in the 'r band - more likely to be an particle strike.
That green area is an artifact - if we look on SkyServer it is not visible. A field runs through the image. Happy hunting 😃
An #artifact - the green images are quite common at the edges of the survey area.
Just a average star from our galaxy 😃 Neutron stars would not be visible in these images 😉
No sign of lensing for me 😃 Nice #bar!
The host galaxy looks a bit different from the image posted here
I would agree - 2 foreground stars 😃
yup - #artifact
All local stars combined with filter / imaging errors. #artifact
Not a nebula - a galaxy! 😃 I would go with a barred proto spiral. The blue colour indicate a young galaxy with star formation.
It is a satellite trail that has been partially removed from the image. Hope this helps!
That blue thing is a star from our own galaxy 😃
They are all foreground stars from our own galaxy. Focus / imaging errors. #artifact
Not an asteroid 😃 a #satellite trail
Not a merger 😃 Just a complex #barred #multi arm spiral 😃
Only ever classify the object directly at the center - star / #artifact for me 😃
No lensing 😃 but you said it - three galaxies!
#zgotw
No explosions 😃 That is an out of focus star from our own galaxy. #artifact
Possible #AGN - no spectra, nothing on NED or SIMBAD.
A very bright foreground star! #artifact
I would go with a faint spiral arm 😃
star 😃 #artifact
The green speck looks like a cosmic strike - only in the 'r band.
No 😃 It looks like a single galaxy at the center with some spiral features. Or are you talking about another feature in the image?
They are all foreground stars 😃
Yes - #artifact
Not really - it is not that uncommon 😃
nice #bar 😃
Looking at the colours of the galaxies, the top one is a lot closer than the central galaxy. Slight #overlap
Yes, a star 😃 #artifact
A lovely elliptical galaxy 😃
I am more tempted to say #overlap - few signs of interaction in the smaller edge-on galaxy.
I don't think it is radioactive 😃 it could be 2 galaxies, another possibility is a dust lane 'separating' the galaxy.
I would say yes - it is clearer on the SkyServer image. Possible #AGN candidate
Always classify the object directly at the center, in this case it is the fainter of the two galaxies.
#artifact foreground stars
Only ever classify the object directly at the center! The other galaxies will have there own chance to get classified in another image.
Most likely foreground stars that are very out of focus due to imaging errors - classify as star / #artifact
Just a slight colour artifact - no outside influences 😃 Over-saturation due to the brightness of the galaxy.
That line is a diffraction spike from the star - an optical artifact - it is not real 😃
Unlikely 😃 The orange central object is a far distant galaxy, the bright white / green object next to it, is a star from our own galaxy.
The bright object on the far left is a foreground star from our own galaxy - no interaction 😃
No, artifacts generated by imaging errors.Classify as a star / artifact and move on to the next classification 😃 #artifact
Sadly not 😃 All foreground stars from our own galaxy. #artifact
This is a fairly young spiral galaxy so the blue bits are not gas (per se) but regions of star formation.
The foreground stars are in our own galaxy, so no merging with more distant galaxies 😃
Where about in the image? On the left edge? or within the galaxy itself?
Have a read of this thread here for more info 😃
They are all foreground stars - there were problems with imaging when the photo was taken. Classify as a star/artifact 😃 #artifact
Foreground stars #artifact
I would say foreground star - SkyServer agrees 😃
and we have an #AGN - even better 😃
A spiral galaxy 😃 The arms have just backed onto themselves to give the appearance of a ring.Nice!
It is a smooth or elliptical galaxy 😃
I would go for merger, some interesting colour artifacts.
A merger of 2 galaxies - you can also see hints of starformation triggered by interaction. The larger orange object is a foreground star.
What a stunning spiral galaxy! Did you have a question about it @dderek? 😃
#artifact - the colours of the stars are not real, all of these images are processed to highlight galaxies.
Another option could be gravitationally bound, but for me #merger - similar photoZ and early signs of interaction.
No it is not star at the center but a AGN 😃 Nice!
Not irregular at all - a fuzzy spiral galaxy 😃 Irregular galaxies will have clumps of star formation and will be very irregular in shape.
I would say galaxies and by looking at the colour they are a lot closer than the central galaxy.
That streak is a diffraction spike from a bright foreground star just off screen to the upper left 😃
I am more inclined to go with spiral arms or pseudo ring 😃
..another possibility is foreground star, but I am not convinced of that. I will add it to the list to be looked at by the Science Team 😃
Not likely to be an optical artifact, as it is visible in all filters. Skyserver has it listed as a galaxy - which it certainly isn't...
#artifact - All foregrounds stars - problems with the imaging caused the weird colours.
They are all foreground stars - so in future classify as star / artifact 😃 #artifact
Classify as star / artifact and they will get removed from the dataset 😃 #artifact
The two objects are unconnected - the orange object on the left is a foreground star.
The denser object is a foreground star, so it is a lot closer than the galaxy.
If they were close enough they would eventually merge - although in this case I am not seeing many signs of interaction.
Imaging / filters errors caused the strange discolouration in this image - #artifact
Not a galaxy but a foreground star from our own galaxy - #artifact
It is a foreground star from our own galaxy - #artifact
That is most certainly a galaxy 😃
Yes, a coincidence - they are foreground stars from our own galaxy 😃
Not a supernova - but a foreground star 😃
Sorry guys - #no-xshape - we are interested in the shape of the bulge not the nucleus.
???
If you had read our replies you would know the answer 😃
#no_xshape - only ever tag the object at the center, the other galaxy will have its own image. 😃
#no_xshape
outer edge? right as in right, or as in correct?
@Mjtbarrett - awww thanks 😃 But trust me, the world is a better place without me singing 😃
Most likely foreground stars - but something went wrong with the imaging. In future just classify as a star / artifact 😃 Nice art 😃
I am neither Alpha Aurigae or cappella.
Zookeeper can confirm my identity 😃
What is your point? @ planetaryscience?
...and I don't sing....
Aaahhh, my nick. I named myself after one of my favourite stars 😃
What is pseudo?
No signs of gravitational lensing 😃 The 'arc' is a spiral arm. We love answering 😃
lol 😄
Not a ring - the spiral arms have wrapped around the galaxy creating the impression of a ring 😃 Nice galaxy!
All foreground stars - nice chance alignment 😄
#artifacts
BTW - a foreground star 😃
Have a read of this thread - more information on artifacts etc...
Most likely foreground stars - we can see a lot of similar objects in the image.
They are spiral arms - have you tried using the 'invert' function? It is really helpful 😃
Yup - the well defined orange object on the left is a foreground star.
They are both foreground stars - have you read this thread yet? 😃
@ekristia - we have been answering all your questions for the past week with no reply. Please let us know you are reading our replies 😃
The 'tail' is a spiral arm. The 'blob' a foreground star. What is not clear is what caused the arm to be so disturbed.
The arms are actually quite well defined 😃 Have you tried using the 'invert' function?
They are all foreground stars - mark as star / artifact.
Not a line of stars - it is a satellite trail that has been removed from the image leaving behind a slight artifact 😃
Not a lot on NED, nothing on SIMBAD.
Looking at it some more, I do not think the objects are connected. Sadly, no spectra.
The central object is the larger bright blue blob at 12 - I do not think it is a merger. I am thinking starburst is more likely... odd.
A spiral arm 😃
All artifacts 😃 Looks likes there were problems with the scope when this field was imaged- Sorry!
Have a read of this thread here- more info on the different types of artifacts you will come across
The lower object is a foreground star from our own galaxy - the bright center is an artifact caused by over saturation / exposure 😃
They are all foreground stars - looks like there were some imaging problems with the scope. Classify as star / artifact 😃
Have you read our other replies?
It looks like the different colour filters were slightly misaligned - these are artifacts. Other objects in the field have the same problem.
And you would be correct 😃
To be honest, there is really no point in tagging any of the old surveys...
Exactly that - the images were digitally altered to change the colour of the galaxy.
As they have been digitally altered they should not be added to the collections.
A galaxy - stars tend to be more cleanly defined around the edges 😃
The white object is a foreground star that is superimposed on a spiral galaxy - so no gravitational lensing 😃
It is a foreground star...
I will be honest, it is not very x-shaped - I would personally leave it out of the collection.
The red line at 10 in the galaxy? or the red dots?
No gravitational lensing - two galaxies with some colour artifacts 😃
All these objects are foreground stars from our own galaxy- So no gravitational lensing 😃
That is a foreground star 😃 Remember to only ever classify the object directly at the center - but commenting on them here is fine!
#no_comet
They have very similar redshift (0.051 and 0.052) so they are at similar distances to us. Taking into account the interaction - merger 😃
Look like a #pseudo-ring as well 😃
It is a foreground star - the weird colour are artifacts 😃
They are both foreground stars from our own galaxy. We have to look through our own galaxy to see the more distant ones 😃
Discussion updated 😃
Hi and welcome nachoir 😃 Yes, artifacts from foreground stars - looks like a problem with the green filter - Sorry, and happy hunting!
I don't think there is any typical figure as it is dependant on so many factors (gas, dust etc...) - I will see if I can find more info...
These are artifacts - looks like there were problems with imaging. More info here
I would go with 2 galaxies merging 😃 Loads of interaction.
A foreground star - have a read of this thread here for more info 😃
These are artifacts, caused by imaging errors with the scope - just classify them as star / artifact 😃
Sorry! no merging galaxies - foreground stars 😃
The bright object on the right is a foreground star from our own galaxy 😃
These are all foreground stars from our own galaxy. No signs of lensing, it is just artifacts caused by over saturation 😃
Hey @ekristra - are you reading any of our feedback? Sorry for being so abrupt - but we have replying to you all day...
Also have a read of this thread - here 😃
Hi and welcome @ekristia - these are foreground stars - have you seen the other replies we have left you? 😃
They are all foreground stars - nice chance alignment 😃
star / artifact
It is another galaxy so no gravitational lensing for me 😃
There is a much larger galaxy that is off screen to the top right. Have a look on Skyserver - it is quite awesome 😃
An irregular galaxy with loads of star formation 😃
Nope - diffraction spike 😃
You may need to click on 'get image' on the left 😃
Not broken - just cropped. Full image here
Not disturbed 😃 A normal looking 2-armed spiral galaxy - very fuzzy, but still normal 😃
I am also thinking #overlap 😃
Actually this galaxy is fairly undisturbed! We only use the term 'disturbed' if the galaxy is asymmetric 😃
Galaxy with spiral features- pseudo ring perhaps?
They are all foreground stars 😃 This thread here has more info 😃
Always classify the object at the center - in this case the edge-on spiral galaxy. Merger with possible collisional ring on the left 😃
It is a galaxy - it is a overlap 😃 The two galaxies are not interacting.
#no_nebula
A elliptical or smooth galaxy - galaxies tend to have more fuzzy edges, unlike stars 😃
It is a spiral 😃 You can see the arms protruding from it, if it was less fuzzy, it could be a gorgeous one 😃
A satellite trail 😃 They move so fast they only get captured in a single filter 😃
I can do three if you want? Just more work!
Dark nebula.
Do you think we need separate collections for all types of nebulas? I was hoping we could get away with one instead of 3?
Very #disturbed, I would say the orange objects (amongst others) are foreground stars. Clumps of #star-formation.
Finally got this one to classify 😃 Nice 😄
As pointed out below - an irregular galaxy with starbursts 😃
I would say no, more inclined to go with a S0 lenticular galaxy 😃
Artifacts 😃 Looks like the whole field was out of focus.
I would say so 😃 Several arms are clearly visible 😃
...lower right looks a lot closer. A difficult one. I will add it to the collections so we can have a closer look. #lens
It looks interesting, but just the difference in colour between the arc and counter image discounts lensing. Top left more distant galaxy...
Interesting spectra associated with this galaxy, high OIII and Ha emissions... Starburst at lower 6?
The 'pearls' are all foreground stars from our own galaxy - hope this helps! 😃
No, but its fine! A set number of volunteers will also classify thisimage, so mistakes iron them selves out. We are all new at this once 😃
Welcome 😃 They are artifacts caused by imaging errors with the telescope. From the looks of it I would say stars.
Yes 😃 They are all foreground stars.
Thank you for being a part of it 😄
It has already been looked at by several Scientists, so if they had found it interesting it would already be on a list 😃
Classify it as a star / artifact 😃
It means that there is no signs of gravitational lensing 😃 Just cleaning up the collection 😃
IRAS F21274-0301 aka Abell76 - #collisional-ring [5] galaxy.
Interesting... it has turned up in a paper about collisional rings. Will need to read a bit more... Read Here
It is a galaxy - originally misclassified as a Planetary Nebula - 2 notes in NED, and loads of references 😃
Apart from the #edge-on galaxy all the other objects are foreground stars 😃 #no_lens
#no_lens a lovely #merger 😃
A much more distant galaxy 😃 #no_lens
Stunning galaxy - #star-formation not lensing 😃 #no_lens
Looking at the Skyseerver image I will go with #no_lens - nice #merger 😃
#spiral arms, sorry #no_lens 😃
#overlap for me too - no signs of interaction. Also #no_lens
#no_lens - amazing #starbursts in an #irregular galaxy 😃
Looks like an #overlap - the alignment of the 'lens' is wrong - we would expect it too wrap itself around the lensing galaxy.#no_lens
It is an #artifact - the weird colours are caused by over saturation #no_lens
#star-formation in spiral arms, more visible in the 'r filter 😃 #no_lens
#merger for me - look at all that starformation 😃 #no_lens
A bit too lightweight to cause lensing - very disturbed, possible merger. #no_lens
Lol - nice one 😄 It even has a face 😃
#star-formation #no_lens
See below for explanation - #no_lens
A merger 😃 no signs of lensing 😃 #no_lens
#no_lens - #collisional-ring [16] perhaps? 😄
Nice 😃
#no_lens - a spiral galaxy with lots of star formation in the spiral arms 😃
A foreground star 😃 #no_lens
Wow - stunning 😃 Looks like a text book example of a #pseudo-ring, sadly #no_lens
Hmmm,nothing in the different filters or on SkyServer - #no_lens
I would go with #ring 😃 #no_lens
#no_lens - foreground star on the left 😃
Looking in the different filter, I see no sign of lensing 😦 #no_lens
#no_lens - see below 😃
Alignment is also a bit odd.
Slight discolouration in lower right of galaxy at 4. Bit diffused to be a #lens, but will have a closer look. Most likely star formation.
#MCG No spectra, but we have a stunningly bright core.
An #irregular galaxy with #star-formation 😃
No galaxies involved - read below 😃
A bit too far from the 'lensing galaxies' to be a lens, also the alignment is wrong 😃
#no_lens - a lovely merger 😃
#no_lens reason below 😃
#no_lens - overlap for me too 😃
#no_lens - the 'lens' and 'lensing galaxy' are all part of the same group. The 'lens' will always have a different colour to the galaxy.
#no_lens - spiral galaxy 😃
#no_lens - looks like a ring. Also lenses will be quite different in colour to the lensing galaxy.
2/2 ...single image we would never be able to tell 😃
1/2 The surveys we are looking are aimed towards looking at distant galaxies not stars within our own galaxy, just by looking at this ...
Widescreen here
Click here for the widescreen view
We have a nebula in our midst 😄
2/2 and a yellow foreground star in the lower left 😃
1/2 Not a overlap 😃 We only use that term when two galaxies are overlapping. In this case we have a galaxy with star formation...
Certainly not a irregular galaxy and not so sure about dustlane 😃 Star formation triggered by merging and a slight artifact.
It is a star 😃 But not all stars in the SDSS survey are imaged as such - we do get normal ones! This was caused by a imaging error.
These are all artifacts caused by imaging errors. Sometimes the filters are misaligned or not focused. here
I would say yes 😃 #edge-on galaxy
It is a satellite trail 😃 They move really quickly so we only capture then in a single filter, in this case red 😃
The dot is a star from our galaxy - I guess alan1001 was referring to the extended arm at 2 and 12. Not disturbed for me, 3 arms?
Not a 'gpair' - a galaxy and a foreground star. Only hashtag objects you are certain about 😃 For the newbies:-)
The filters could of been misaligned, there could of been bad observing conditions (eg. very windy) or a technical problem with the scope.
Not a lens or a merger 😃 I would go with spiral arm. Clearer if you view it in the different filters.
An artifact:-) If you have a look at the skyserver image we are clearly in the middle of a star cluster. All the objects here are stars 😃
Two galaxies merging 😃 Simbad has it flagged as a AGN as well. Nice!
It is 2 separate objects, in this case foreground stars. Look like the observing condition were not that good, hence the fuzzyness.
I would say no 😃 No interaction between the yellow galaxies and all the other objects are foreground stars 😃
It is a spiral galaxy with a really bright core. Possibly also contains a bar 😃
The galaxy is very disturbed but it is difficult to tell if the galaxy at 11 is involved. No spectra for either. My gut says no...
The galaxies are not overlapping 😃 To call it an overlap they will need to cross over each other with no interaction. Line of sight 😃
No worries 😃 #no_lens
It would be nice to see a bit more curvature in the arc, but a nice addition to the collection 😃 Now to try and find the counter image!
Neither 😃 Looks round to me - it is only due to a slight colouring artifact (red on left, yellow on right) that is has that appearance.
I thought as much 😃 Another one to add to the glossary that is being compiled 😃
FOV = Field of View 😃
Not enough curvature for it to be a lens - I would go with #overlap #no_lens
#no_lens #ringed galaxy
#no_lens #spiral galaxy
#barred #spiral #ringed
That is a foreground star from our own galaxy. But look at that barred spiral at the center! Awesome 😃
#AGN
#no_lens overlap
The object to the lower right is a foreground star - they tend to be more clearly defined than galaxies 😃
Imaging artifacts 😃
They are all foreground stars from our own galaxy - widescreen view here Click on 'Get Image' on left.
The orange object is a foreground star from our own galaxy - so it is not connected with the blue galaxy at the center 😃
They are also galaxies, looking at the colour a lot more distant than the central galaxy 😃
That dark ring is an imaging artifact caused by the ccd camera being overwhelmed by the brightness of the core (over saturation)
It is a star in our own galaxy, so it is close compared to the galaxy at the centre 😃
Galaxies are more diffused than stars, also the weird colours above are tell tale signs of artifacts caused by stars 😃
No 😃 You can't change your classification once you have submitted it. Have a read of this thread here
Hi and welcome @stefku - they are both foreground stars, so no merging 😃 In future you can classify it as a star / artifact 😃
Some galaxies are just irregular / asymmetric in shape 😃 I can't see anything interacting with it. #irregular for me too.
link the image is slightly rotated, and you may have to click on get image (on the left)
It is a diffraction spike from a bright star just off screen to the right - a #artifact 😃 I will post a link to the widescreen view...
Another foreground star from our own galaxy - #artifact 😃
The bright object is a foreground star - just tag as #artifact 😃
I would of classified it as a star / artifact 😃 something went very wrong with the imaging.
I will get someone to have a look 😃
All foreground stars 😃 The weird colour is due to a error with the green filter in the telescope.
Nice #bar 😃
It looks like they are unconnected - I would say the edge on is a lot further away than the central galaxy.
It is a artifact - a foreground star 😃 The brightness caused some issues with the optics of the ccd camera.
It is a diffraction spike from a star just off screen 😃
It won't be a dwarf galaxy - wrong colour and too big! Could be a companion galaxy or a foreground star 😃
Stunning! 😃
Personally I am not entirely convinced the object at the bottom of the galaxy is a star...
A galaxy directly at the center - they are more fuzzy than stars. NED has the other two objects as foreground stars. #asteroid on right 😃
Clearly two separate objects, and NED is not always correct! . The whiter object could possibly be a foreground star?
I would go with dwarf galaxy 😃 There are quite few references on NED for it.
I would say foreground star - to well defined to be s satellite galaxy. No spectra so there is not much else we can learn from the object.
Yes they are all foreground stars 😃 The strange colour is due to a filter / imaging error.Sorry!
Hi Thom and welcome 😃 It is two galaxies that are in the process of merging, hence the distortions and starbursts (the blue bits)
Then classify it as such 😃 It is your opinion we are looking for after all 😃
I am more inclined to go with a spiral galaxy, see how the points are very angular and the arms extend futhur than the ring?
Just a single galaxy 😃 The white object is a foreground star from our own galaxy.
Star formation in a irregular galaxy - if you scroll down you can see you are not the first to query it 😃
I would go with spiral arms - see how they don't make a perfect ring?
Spectra flags it as galaxy, the blue ring could be star formation but I would still err on the side of caution and tag as possible #lens
Too fuzzy to be a star, certainly a galaxy. Interesting blue ring, needs a closer look...
You might have to click 'get Image' after following the hyperlink 😃
Yes, it is a diffraction spike from a foreground star off screen to the left. Have a look here for the star..
True, but sadly there is nothing we can do about until Talk gets revamped 😃
Welcome 😃 Only ever classify the object directly at the center, in this case a smooth galaxy . That bright object is a foreground star.
I would go for star as well 😃 Looks like was an issue with the green filter.
I have answered you in the discussion thread 😃
ps that is a little bit uncalled for 😃
How far upper right?
No spectra? To be honest this looks like a pretty ordinary galaxy...
AGN? why?
One for the #alphabet 😃
No merging for me 😃 The star on the left is from our own galaxy -it only looks connected by line of sight 😃
Actually, I would call this a Low Surface Brightness (LSB) galaxy or dwarf galaxy.
It is a spiral galaxy with loads of star formation - that is what is causing the blue colour 😃
It is another galaxy 😃 From the looks of it, it is not connected to the central galaxy 😃
#no_lens foreground stars.
I would go with overlap - although it is very fuzzy, we do not have much interaction.
Looks like foreground stars - something went very wrong with the filters!
The black dot is a artifact caused by over saturation, we have this problem with really bright objects 😃
It is rather disturbed, looks like we have a sattelite galaxy to the lower left 😃
I would say the two lower 'nuclei' are foreground stars 😃 They only look connected to the galaxy by line of sight.
I am not so sure it is barred - the image is very fuzzy. but I do see a spiral pattern. Apart from that there is not much we tell 😃
Your classification sounds good to me 😃 I might of excluded 'irregular' - but that is just me 😃
#no_lens #ring
Yes 😃 they are both stars
I will try and dig around some more...
#NGC According to the papers cited it is star formation triggered by merging galaxies, but it also looks a bit odd in my eyes...
The blue bits in the galaxy are area of dense star formation. The white spot a foreground star. No merging for me 😃
Most likely foreground stars from our own galaxy - the telescope misbehaved and we landed up with these artifacts 😃
These are all artifacts - something went wrong with the imaging. Most likely foreground stars 😃
No spectra but we can see interaction between the two, early stage #merger. Nice!
#NGC
The object at the center is an elliptical galaxy with a bright core. All the other objects are foreground stars 😃 Very Fuzzy image!
Nice barred spiral - definitely not a edge-on galaxy 😃
Stunning galaxy 😃 #barred #spiral
The bright object at the top of the iimage is a foreground star from our own galaxy 😃 Nice barred spiral at the center!
This galaxy has spiral features 😃 They are somewhat blurred, but still visible. Have you tried looking at the inverted image?
I am in two minds about this - I would call the outer 'ring' a psuedo ring, but the inner one looks a bit more convincing.
This is a foreground star from our own galaxy 😃 The odd colouring is due to imaging errors. More info here
I was just posting in that thread!
Disturbed isolated galaxies: indicators of a dark galaxy population?
#UGC 04722 - several notes on NED, looks like this on has caught the interest of several astronomers 😃
I can't see another galaxy in the vicinity on SkyServer - perhaps a result of a fly by?
Classify it as a star / artifact 😃 This is a star from our own galaxy, the weird colours are artifacts caused by over saturation!
This is a galaxy - so it is made up of billions of stars 😃 Looks like a stunning #ring galaxy with a #bar and a lot of star formation!
It is a bit too orange and 'regular' to be an irregular galaxy 😃 If it was blue with loads of starformation and a very irregular shape...
#no_lens artifacts 😃
Looks like a foreground star 😃
It is a almost edge on / disk galaxy with a stunning dust lane 😃 It is just perspective that makes it looked warped 😃
#no_lens bad pixel?
#no_lens #collisional-ring [4]
#no_lens spiral arms and artifact
#no_lens spiral arm 😃
#no_lens Looks like a merger, #collisional-ring [15] viewed head on?
Merger, foreground stars - a lot going on in this image 😃 But, #no_lens
Foreground stars in front of a spiral galaxy. 😃 #no_lens
#no_lens looks like we have a merger! Collisional ring perhaps? 😉 #collisional-ring [14]
#no_lens foreground stars 😃
#no_lens artifact
I would go with overlap, the colouration and appearance are not conducive to gravitational lensing. #no_lens
In this case I am more likely to go with artifact, but will keep in collection for Dr Phil to have a look at.
#no_lens The orientation of the arcs to the 'lensing galaxy' is wrong. 😃
#no_lens - star formation,but thanks for flagging it! 😃
#no_lens - spiral arms and star formation.
I do not think it is a merger - no interaction. Overlap for me. 😃
Hmmm, Initially I would say no, but the more I look at it, it is a yes 😃
Not a overlap 😃 A foreground star and a young galaxy with a lot of star formation...
#no_comet - it is a asteroid...
Um, this is not an elliptical galaxy...
Sorry - not a ring 😃 Spiral arms...
Unlikely to be a overlap.. looks like we have interaction with another galaxy off screen.
Most merging galaxies do eventually combine, but this looks like an overlap 😃 ie. they only looks close together due to line of sight 😃
No bar for me! Nice 2 armed spiral 😃
Sorry! It is not irregular enough to be an irregular 😃 Also lacks the vivid blue colouring. I would go with disturbed 😃
They are all foreground stars from our own galaxy 😃
It is a foreground star, read the comments below 😃
Only classify the object directly at the center!
Snap 😄
Not a green pea - a foreground star. See this image here http://tinyurl.com/lu4w5hd There are similar objects in the area 😃
All the objects in this image are foreground stars - so you are right, no galaxies 😄
#no_lens nice ring!
Thank-you Brooke and Chris!
It is a foreground star from our own galaxy 😃
Hi and welcome @Sijtze 😃 I would go with a barred spiral galaxy, ring perhaps? It is your opinion that is important! 😃
The image is not missing - it is at the edge of the survey area. Have a read of this thread here 😃
That is a pretty one 😃 Nice find!
I thought so, but is doesn't explain the similar blue objects 'lower' down in the skyserver image.
I will flag this one up again - I am still as confused as the day I first saw it.
This one still makes me sit up and notice 😄
#no_lens early stage merger 😃
#no_lens foreground star at lower right of galaxy.
#no_lens nothing to suggest it is a lens looking at the different bands. Similar discolouration in nearby galaxies.
#no_lens spiral galaxy
#no_lens #dustlane #NGC 3703
What a gorgeous #barred # spiral 😃
Always useful to get into the habit of checking 😃
A difficult one, if you look in the different filter - there are 3 distinct cores. Not entirely convinced the foreground galaxy is involved.
Nice one!
No - it is not an irregular galaxy 😃 Irregulars will have a more vivid blue colour, with clumps of star formation, along with odd shape.
No gravitational lensing 😃 A barred spiral galaxy, the 'arcs' are spiral arms.
More info here 😃
It is a foreground star from our own galaxy - the weird colours are artifacts caused by filter / imaging errors.
#no_polar 😃 The 'select' statements for the collections are very particular... 😃
It's a collection challenge, - check your inbox 😃
#no_polar
Fancy taking up a challenge?
I think that is a round bulge - #no_xshape
looking 😃
Not too sure - nice linear pattern, Will flag it up!
Good to see you back @elizabeth 😄
Most likely 😃 - that is where we come in, we analyse a image - not rely on a algorithm to provide a answer 😃
No overlap - Sorry. Most likely a foreground star.
Sorry, I do not see a overlapping galaxy 😃
That would be my initial reaction, but I am not so sure 😕 Very clean and precise, fits the SN profile. Perhaps someone can have a look?
The answer is revealed below 😃 Read this here for more info.
Spectra suggests a #QSO - will wait for a professional to evaluate...
Looking at the image in different filters makes me more undecided - the blue bit at the center looks unconnected.
That is a odd one! I will get a scientist to have a look 😃 I was thinking merger, but I am not sure 😕
Possibly - might have to wait a million or so years 😄
Wow! That is a stunning neighbourhood 😄
Only ever classify the object directly at the center! Ignore all other galaxies unless they are interacting with the central galaxy! 😃
I think you mean #no-bulge 😃 I would personally go with #irregular
Difficult to say - but I would of classified it as having a bar 😃
Have a read of this thead here - these are artifacts of foreground stars 😃
It the computer that thinks it is a galaxy - that is where we come in 😃
...certainly nothing to do with redshift 😃
@shaunessey - Hi and welcome - have you read that link I sent you in the other comments? The colours are artifacts, due to the filters...
Sadly not 😃
Read answers below 😃 Not a cluster or an irregular galaxy.
Lateral or vertical? Looks like an artifact either way 😃 Loads of background noise to go with it.
Read this here for more info on artifacts 😃
No merging - we have a foreground star on the right and there is no interaction between the galaxies. Looks like different redshifts too...
#no_lens - these are all foreground stars 😃
Just a foreground star that looks like it is next to to a much more distant galaxy, all due to 'line of sight' 😃
The blue object in the right corner? That is a foreground star 😃 Have you read this thread here ?
I would go with galaxy 😃
Artifacts caused by imaging / filter errors - have you read this thread here? 😃
And you would be right 😃
Neither 😃 both of those objects are foreground stars from out own galaxy. More info in this threadhere
Zoomed out http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=356.1143653&dec=67.32301473
An artifact - looks like we has a problem with the filters / imaging. Usually happens at the edge / ends of the stripe.
They are all foreground stars 😃 looks like a star cluster!
The core or bulge does look a bit off center - I can also see some spiral features 😃
Looking at the SkyServer image it is still very fuzzy! It is listed as a star, but that may not be accurate. Happy Hunting 😃
#no_lens - #ring or #spiral
the object directly at the center (that you need to classify) is indeed a star. The elongated object to the left is a galaxy 😃
It is still a galaxy - I would go with a low surface brightness (LSB) or dwarf galaxy. Does look a bit irregular too.
The blue bits are regions of intense star formation. Really nice #irregular galaxy 😃
They both look like stars but it is really difficult to tell what they are, due to filter / imaging errors 😃
Just classify it as a star / artifact - which it is 😃 It is one of the images that is at the edge of the survey area.
😄 I will post more details in the collections thread in a bit...
No worries - I am just at the beginning of my quest to standardise all hashtags - so we can build better collections!
Less confusing rewrite done!
...for the collection, because that was the request from one of the volunteers 😃
'Boxy', 'X-Shape' or 'Peanut' all refer to the same type of bulge seen in a edge-on galaxy, I chose 'x-shaped' for the hash tag...
You should nominate it for the galaxy of the week 😃
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=356.84900732&dec=68.24343681
It is at the edge of the survey area, all objects have been turned into artifacts. I will post a link to the wide view in the next post
#no_lens #collisional-ring ? [7]
The orange object directly at the center looks like an elliptical / smooth galaxy 😃
It will be looked at by loads more people, so any error will get ironed out 😃
They are all foreground stars from our own galaxy - the weird colours are artifacts caused by imaging / filter problems. 😃
#asteroid
Not necessary 😃 This way another user who has the same question, will get the answer too 😄
The dark spot is an artifact caused by oversaturation - you can read more info on different artifacts here 😃
Hi and welcome 😃 The bright blue objects are both foreground stars from our own galaxy - more info here
Thanks 😃
...another vote for #polar-ring 😃
We usually use the term 'diffraction spike' to refer exclusively to artifacts generated by the telescope optics around stars...
This one certainly looks a bit more x-shaped 😃
The UKIDSS images can be a bit misleading, looking at the SkyServer image I would say no, but it could go either way.
Where? Looking at the different filters it is still a single core.
#no_lens but really interesting #ring? Worth a closer look 😃
#alphabet
The white'ish object to the left is a foreground star 😃 No merging!
#no_lens foreground stars
#no_lens lovely #ring
Look to the bottom left , you will see the RA / Dec 😃
It is a foreground star:-) But interesting cluster!
#no_lens more likely star formation.
But there is no bar 😕 Even looking in the separate filters.
Satellite trail 😉
we also have a #bar in there 😃
I can imagine! Nice one, and welcome 😃
This is a odd one, I do not think the two objects are connected 😕 I will have a closer look later.
3 foreground stars from our own galaxy - they only seem to be in a line due to perspective 😃 A optical illusion - 'line of sight'
No, they are all just stars from our own galaxy.
I would say it is a foreground star - the green colour is caused by a problem with the filters (in this case green!) in the telescope 😃
You could say that - it is an artifact seen at the edges of the survey area 😃 #endofstripe
#no_lens for me, the colour difference between the 3 points suggests they are 3 individual objects.
The orange lights are all foreground stars from our own galaxy. Never a waste of time to ask a question 😃
It certainly looks like we have some interaction going on between the 'larger' spirals. Star formation is another good indicator 😃
The dark point is a artifact caused by over saturation. You can find out more info about artiacts here 😃
The object at the center is not a star - it is a galaxy with spiral features 😃
Only ever classify the object at the center 😃 But, it is okay to comment to them on talk 😃 Happy hunting!
See answer below 😃
A foreground star with some intresting artifacts, you can read more info here 😃
It is a foreground star from our own galaxy, the weird colours are artifacts. More info here
Yes 😃 A foreground star with some artifacts, more info in this thread here
Things are different now - voorwerpies are not that uncommon. Sorry if you took what I said in the wrong way, but it was a valid point 😃
No worries 😃 We are here to help!
The central object is a galaxy, the orange object above it is a foreground star. They just look close together due to line of sight 😃
#no_lens #spiralgalaxy
#foregroundstar middle of a star cluster #no_lens
...something odd or first to add to a collection? So much easier just to credit it to all the Galaxy Zoo volunteers 😃 just my opinion
It is more complicated than that 😃 How is it determined who gets the 'credit'? First person to classify it? First to say there is...
They are all foreground stars, it is a chance alignment, caused by 'line of sight' 😃
#no_lens chance alignment, the einstein radius would not be that large.
#no_lens starformation
I would go with yes 😃
You are right! It is a foreground star from our own galaxy, it only looks close to the galaxy due to line of sight 😃
#no_lens foreground star
#no_lens #spiral
#No_lens #spiral #bar
#no_lens spiral galaxy with foreground star.
That dark spot is a artifact cause by over saturation. The core of the galaxy was too bright for the camera.
It is a irregular galaxy with clumps of star formation.
Hi MikeOborn 😃 We only use the 'overlap' tag when referring to galaxy / galaxy overlaps. Bill Keels thread on the forum has more details.
I am thinking artifact perhaps? Only in one filter.
Hi and welcome aimee 😃 Those are foreground stars from our own galaxy. Have you read this thread here ?
More info here
This is a foreground star from our own galaxy - all the colours are artifacts caused by oversaturation 😃
#no_lens personally, I would also go for #ring
more likely starformation #no_lens
But it is still cool to look at! 😃
I more inclined to say no, the colours are too similar suggesting similar redshift, also no sign of a counter image. #no_lens for me.
They only appear to be close together due to line of sight 😃
Only classify the object at the center, or else it could be confusing 😎
@mrgiezen - I just realised you were talking about the 'dust lane' - yes, it is more visible in the lower one 😃
I don't think so - they all look like galaxies... I will have a closer look.
Overlap for me, no interaction between the galaxies. The bright object just above the central one is a foreground star 😃
Nice! #lens
#no_lens - this is a edge on galaxy, so only the bulge would have the mass to generate lensing.
#no_lens - this is a edgeon galaxy, so generally only the bulge would have the mass to generate lensing. Also a bit far from the galaxy.
#no_lens for me, most likely star formation.
#no_asteroid, #satellite
#no_asteroid
#no_lens - most likely star formation.
Nice! 😃
It looks like an artifact caused by over saturation - can you see the other objects have similar discolouration? 😃
Hmmm, I don't see a bar, but you could classify it as a ring or spiral. All up to you! 😃
#no_lens - looks like a #merger 😃
Not entirely convinced NED is correct, but I will keep it in the collection 😃 Will search for more data later...
#no_lens, star formation in spiral arms.
#no_lens - no noticeable lens galaxy. More likely star formation.
#no_lens - star formation in spiral arms.
#no_lens, star formation is most likely cause of the blue blob on lower right.
#no_lens, more likely overlapping galaxies.
#no_lens, I would expect the lensed objects to be closer to the central galaxy. Chance alignment for me. Also, mass is quite small.
too much back ground noise to tell, #no_lens
An artifact, not a lens #no_lens
Yes 😃 I would of flagged it as one! Oh, and welcome to Galaxy Zoo! 😄
too fuzzy to be lensing #no_lens
I would also go with spiral #no_lens for me 😃
Actually, the redshift is quite similar 😃 0.020 for the top galaxy and 0.019 for the central galaxy
#no_lens 😃 We would expect the arc to go round the lensing galaxy.
Too fuzzy and too much background noise #no_lens
An artifact on the left and star formation #no_lens
#no_lens - ring / spiral arms 😃
#no_lens - I would also go with spiral arms / ring 😃
It is not a irregular galaxy - do you perhaps mean disturbed? 😃
Looking at the amount of interaction between the two #merger for me.
Yes - blue areas suggest star formation, so lots of young stars! Older galaxies tend to be red / orange.
They are both foreground stars - the strange colour is an artifact. You can find out more info here 😃
The bar have a lot of star formation going on, that is giving it the slightly odd colour pattern.
Irregular galaxies tend to be blue in colour with loads of star formation and irregular shape - would go with spiral galaxy in this case:-)
The bright round object on the top left of the galaxy is a foreground star 😃
PhotoZ (although not that accurate) suggests they are not that close.
I would go with overlap, no visible interaction between the two, even though we have a lot of starformation in center galaxy.
You are right - it is a galaxy at the center! Nice work 😃
I would say both the galaxies are unrelated to each other, so no interaction for me 😃.
nice one!
No nebulas 😃 Looks like we have spiral arms with load of starformation, folding back on themselves.
We have a elliptical galaxy at the center, with a foreground star to the left 😃
WOW - #zgotw for me 😄
A galaxy for me! The colour distortion is a artifact caused by oversaturation of the really bright galactic core 😃
The red / orange objects are both foreground stars - have you read this thread here for more details? 😃
I would go with a foreground star - the weird colours are an artifact caused by overexposure 😃
@lostlens You have been advised several times that if you continue to use incorrect / misleading tags, your comments will be removed.
Thanks Phil 😃
I am still curious...
lol - apparently I am being observed with my musings 😄
awesome 😃
Artifacts from imaging. Foreground star 😃
Where about? so I can have a closer look?
Looks like we had a filter problem! In future classify as a star/artifact 😃
Aahhhh, just tag it as a LSB - I am working on standardising hashtags!
Dark object where?
I do not think they are merging, the colour of the spiral (on the right) suggests it is much closer 😃 #overlap for me!
A planetary nebulae... supernova remnant 😃
#zgotw for me! Looks like we have a #bar as well! Nice 😄
It does look like they are interacting! Stunning irregular, and it looks like we have a hint of a bar! #bar
This can be better be taken up in a discussion.
Certainly. ElisabethB will post the relevant bits - provided we get Bill's permission.
2/2 and after receiving a reply from Dr Keel, please continue to tag overlapping galaxies as 'overlaps'. Other tags may be removed. Thanks!
1/2 Just to clarify 😃 My comments were directed towards the continued misuse of a specific hashtag, not in reference to the image above...
2/2 ...within professional astronomical circles. We should adhere to recognised terms to prevent confusion.
1/2 @lostlens Please can you refrain from tagging overlapping galaxies as 'keeloverlap' - they are overlaps, and referred as such...
An #irregular galaxy 😃 Another vote for #zgotw
I would go with #merger 😃
How so?
It is an #artifact caused by dodgy filters and a foreground star 😃 More info here
In this case I am more likely to go with it not being an x-shaped bulge - but like you said very dim.
Those are most likely artifacts 😃
Yes 😃 the central object is a galaxy, the other objects are stars.
😃 Looking at it from a particular angle, it could be a very small #collisional-ring [21], that could explain the intense star formation
Collection thread here
Never said it wasn't a 'x shaped' or 'boxy' bulge 😃 We just need to all use the same hashtags to create collections.
Can we please keep the hash tag for x-shaped bulges to #x-shaped - as explained in the collection discussion. Thanks 😃
@lostlens - perhaps you should create your own hashtag for non-galaxy line of sight coincidences?
Doughnuts! Yum 😄
Not a nebula 😃 A stunning irregular (possibly dwarf) galaxy with a lot of star formation.
Doesn't look that disturbed!
Blue in galaxies indicate star formation, but I think all of these objects are foreground stars 😃
I would say foreground star 😃
http://skyservice.pha.jhu.edu/DR8/ImgCutout/getjpeg.aspx?ra=357.4891691&dec=66.19810896&scale=6.33792&width=512&height=512&opt=&query=
Part of the cosmic scarf 😃 It is a image from the end of the stripe.
The star is from our own galaxy- The Milky Way - so it is closer to us than the edge-on galaxy at the center.
Another artifact - we seem to be getting a lot of them today!
It looks like the 2 green dots are artifacts - only visible in the 'r filter
#artifact - only visible in the 'r filter - particle strike not removed.
No signs of interaction - no merging for me 😃
No, it looks like the center galaxy is overlapping a more distant edge-on.
#zgotw for me 😃
I think you are right 😃 Interesting satellite galaxy...
Wow - that is a stunning one!
Hi @davidmarine and welcome 😃 causes what?
A coincidence or chance alignment 😃 A mixture of foreground stars and more distant galaxies.
Not so sure the galaxies are merging, not a lot of interaction 😃 Overlap perhaps?
Looking at the other bright objects in the field - I will go with artifact. Misalignment of filters - Sorry!
Yes, looks like a edge-on, or disk - somewhat disturbed. Nice dust lane as well 😃
I would go with spiral 😃
What a stunning #merger!
Foreground star for me!
Line of sight, perhaps? 😃 No visible interaction, so we can rule out merging. Also, remember to only classify the object at the center!
I would say yes 😃 looks like a almost edge on spiral.
Elliptical galaxy 😃
Between what ??? Sometimes we need more clues as to what you are referring too! 😃
Not an irregular galaxy 😃 Irregulars tend to have a lot of star formation, so are blue in colour. Also they are very irregular in shape...
All artifacts 😃 Read the other comments below.
No, looks like an artifact. The other objects have similar discolouration in the lower left quadrant.
Clearly a #merger.
Discounting the foreground star, more like a satellite galaxy.
I am going to go for 2 foreground stars, if you look at the wider image there are a lot of similar objects 😃
No sign of gravitational lensing - a stunning barred spiral 😃
I would go with disk, but we are interested in your opinion 😃
A star - Skyserver is not always correct.
Why do you think the galaxy has an AGN? Interested to hear your view... For me, it is a typical edge-on, No AGN.
It is a foreground star 😃 Something went wrong with the imaging so it looks weird. More info here
Those funny colours on the star on the right are artifacts - looks like some of the filters were misaligned.
You are correct we do have a star on the right 😃 At the center a stunning #barred #spiral. No signs of merging.
All foreground stars from the Milky Way 😃
Hmm, I would not say irregular, rather star formation is giving the arms a clumpy appearance.
The purple object is a foreground star from our own galaxy 😃 More info here
Looks like we are in the middle of a star cluster, so it is quite possible one of the objects is a foreground star overlapping 😃
A foreground star from our own galaxy. more info here
From @klmasters: "we usually reserve the term disturbed for things which are very asymmetric."
In order to classify a galaxy as 'disturbed' you need to look at the shape of the galaxy, not the colour.
Neither - just a very fuzzy almost edge-on spiral galaxy.
#artifact - only visible in 'r filter. Cosmic ray that has not been removed.
#UGC
No spectra available, and it does not have the characteristic colouring of a AGN. I am more likely to say no, just a bright core 😃
More likely a #merger 😃 Look at the interaction between the galaxies, in particular the tidal tails of the upper galaxy.
Agree with @elizabeth - certainly not disturbed!
Not a voorwerpje - star formation in a spiral galaxy.
#artifact at the galactic center caused by over saturation - more info here
Not a voorwerpje - an orange foreground star overlapping the central galaxy.
It does not have the vivid colouring of a voorwerpje - more likely a foreground star overlapping the edge on galaxy..
They are all foreground stars from our own galaxy - more info here
Thanks @C_cld - was having supper, so was a bit busy to look! 😃
Not lensing or a recent merger. Colour is worth a closer look.
Yes - artifacts 😃 All the objects in this image are foreground stars - more info here
I would go with an #irregular galaxy with #star-formation. Can't see anything else that could be interacting with it 😃
Not a binary system 😃 Perhaps it has the appearance of being disturbed as it is a 3 armed spiral 😃
#merger
#UGC 8973
The object directly at the center is a galaxy 😃 The other objects are all foreground stars. More info here
More of a whitish blue, for me 😃
green?
#no_xshape bulge
a collision ring - nice! #ARP #collisional-ring [11]
The colours are not real, it is an artifact. The object is in fact a foreground star. The weird colours are caused by a imaging error.
I would say no on both fronts, but that is just me 😃
I am not seeing anything that suggests this galaxy has a AGN - no spectra, and it is not displaying the bright core one would expect 😉
I am not seeing any signs of lensing? Where about are you seeing it? 😃
Not a merger, we have a foreground star to the lower right and a lovely elliptical galaxy at the center.
Yes 😃 A foreground star.
More likely just star formation triggered by interaction.
They are both foreground stars from our own galaxy. There was a imaging error,so we have some colourful artifacts 😃
@lostlens - last warning. It is not a overlap!
The core only looks unusual because of the color difference between the arms and the core. Apart from that, it is fairly non-de-script.
To do that use a # and follow it with the word asteroid.
No dust lane for me 😃 but I do see an asteroid bottom left - flag it 😃
Not an irregular galaxy - both sides are symmetrical 😃 The slightly blue color in the arms can be attributed to star formation.
The object at the center is a lovely smooth or elliptical galaxy 😃 The bright orange object is a fore ground star - Welcome to the Zoo!
They are stars from our own galaxy 😃
These are artifacts caused by an imaging error. All the objects are in fact foreground stars from our own galaxy.
#xshape
I am going to go with star formation triggered by interaction - see how part of it follows the pattern of the spiral arm?
No arc for me 😃 Looks like stars that have been disturbed from the galaxy due to interaction. Lovely merger!
That is a dustlane 😃 Dust in the galaxy is obscuring some of the light reaching us, causing a dustlane
That looks like a foreground star, no galaxy for me - sorry!
Hi and welcome 😃 That is a foreground star from our own galaxy!
Something went wrong with the imaging / filters - both of these objects are foreground stars 😃
A foreground star from our own galaxy 😃
Yes, it is 😃
#boxy #x-shape
No it does not look like a lens 😃 It is a galaxy with spiral features, a bar and with an very faint outer ring or arms.
#edgeon too! 😃
I would like it looks more like 2 spiral arms crossing back over themselves, than a ring 😃
Sure looks like one 😃
#UGC 11611
No lensing for me, the colour between the lens and 'lensed' object are too similar, suggesting similar redshift.
If we compare the PhotoZ (even taking possible errors into account) of both objects, it is unlikely they are connected.
As mentioned by a previous poster 😉
I don't see anything it could be interacting with. I think the star is just masking the opposite arm 😃
Simbad contradicts itself by also identifying as as G1C - Galaxy in cluster. Mistaken identification?
No spectra and apart from a bright core, there is not a lot to suggest this is a QSO. Sorry 😦
I would go with #cluster - not a lot of interaction so I say gravitationally bound rather than merging 😃
I think it is a galaxy, as it not as well defined as a star. Loads of artifacts in this image - must of been a #windy_night #misaligned
forgot to add - loads of star formation 😃
It looks like a single barred proto spiral galaxy to me - but it is your choice 😃
No merger - the object on the left is a foreground star 😃
With images like this it is difficult to tell. Certainly a bar,not so sure about the ring.
I would go with #merger myself - we seem to have interaction between the center galaxy and the one to the right. Also star overlapping 😃
The blue colour does suggest that it is relatively young - we have clumps of new star formation - Nice!
No planets! To the right is a star. At the center is a very bright galactic core.
The blue areas in the galaxy are regions of intense star formation 😃
Yes, that blue object in the top right is a star 😃
These are all foreground stars from our galaxy - more info here 😃
It is visible in more than 1 filter, so it not an artifact. #voorwerpie? I don't know enough about them to say:-)
#NGC 7731
It is currently on hiatus, we will be getting a new survey later this year. Can't wait!
We found several new ones over on Spacewarps - my pet project 😃
No, chance alignment for me. The colour between the objects are too similar, suggesting similar red shifts. 😃
I think they are unrelated, and it is just by line of sight they look like they are merging. Nice irregular at the center 😃
We do seem to have some slight spiral features, but the resolution of the image is quite bad. Just classify what you see!
Another foreground star - has you read this thread here - more info on the different types of artifacts 😃
Quite disturbed - #merger for me
SIMBAD has it listed as a possible AGN, can't find any spectra...
Not entirely convinced it is one armed - personally I would classify it as two-armed 😃
It looks like it 😃 Stunning #merger
Mid lower left? SkyServer has it listed as a star.
I am not so sure this is a merger. The image is low resolution, so it is difficult to make out features, result of a fly by perhaps?
That's a stunning one! #ZGOTW
They are all #artifacts - something went wrong with the imaging. Sorry!
A foreground star from our own galaxy:-) More info in the discussion you posted 😃
I would go for disturbed disk or spiral galaxy. No lensing for me!
Nice spiral galaxy, I am not seeing any dust lanes? Are you referring to the darker areas between the arms?
I think those are spiral arms:-) No dust for me!
That is an artifact - looking at the SkyServer image we seem to be in the midst of a star cluster 😃
Only classify the object at the center! In this case it is a galaxy. The other two objects are foreground stars 😃
That is a galaxy 😃 Looks a bit disturbed, sadly no spectra available.
An error with the imaging - looks like there was a problem with the green filter. Sorry!
Sure looks like one, SIMBAD agrees 😃
ooopsss - sorry!
Els has several hundred thousand galaxies classified 😃 But she is not one to brag 😄
#ZGOTW
...or a Klingon ship de-clocking 😃
That is unusual! I am not sure if it is a polar ring, as the 'ring' seems more established than the galaxy. Reverse maybe?
Either way, I will get someone to look at it 😃
2/2 the blue colour (star formation) is also a good sign of interaction. Really difficult to tell. Could also be pure chance!
1/2 In this case I might go with early stage merger. The smaller of the 2 galaxies is starting to look a bit disturbed in the lower left...
No worries! 😃
Not a lot of interaction. I think gravitational bound, or totally unrelated is more likely 😃
I would go with overlap, the edge-on to the lower right is a lot further than the central galaxy 😃
Pink colouring looks like an artifact, not likely to be a lens. Have you had a look at the SkyServer image for similar artifacts?
Not entirely convinced it is a ring or barred - there is some suggestion of a polar ring, but not entirely convinced 😃
An error with the telescope- it happens from time to time 😃
It is still fairly symmetrical, so I personally don't think it is disturbed 😃
@Lostlens we have spoken about you deleting and reposting comments, please could you stop doing it. Thanks 😃
Looks like one to me 😃 Maybe early stage, only slight interaction between the two.
Not seeing any obvious signs of interaction -more likely an overlap 😃
Yes, it is a foreground star 😃 Looks like the galaxy may have a bar forming?
lol - that's an awesome one 😃 An imaging error, looks like something went wrong with the filters. One for the Art thread!
They are all foreground stars from our own galaxy - The Milky Way 😃 Have a read of this here BTW Welcome 😃
That is an artifact caused by over saturation 😃
Looks like we have 2 foreground stars overlapping a more distant galaxy 😃
Not lenticular - a edge on disk / spiral galaxy. Lenticular galaxies are a mix between a disk and smooth galaxy 😃
It is an #irregular galaxy 😃 I am not seeing any signs of recent interaction. Happy Hunting!
Wow - stunning a #ZGOTW for sure!
Not lenticular - an edge-on spiral / disk galaxy 😃 The bulge looks #boxy #x-shaped - nice!
That is a diffraction spike from a bright star off screen to the left 😃
Looks like we do have some interaction with the left galaxy. The galaxy to the lower right looks unconnected 😃
Yes 😃 a foreground star.
Stars 😃
Looks like a merger for me - interaction and star formation 😃
lol- Liz will love this one 😄
I would say so, looks like we have several foreground stars in the image. 😃
Does look like a bar and ring, pity the image is not clearer 😃
A star 😃
I am more inclined to go with merger 😃 We have a lot of starformation, that can get triggered by interaction between the galaxies.
yes 😃 the algorithm sometimes gets confused!
The tiny blue 'star' looks like a star burst - nice!
A star 😃 Something went wrong with the imaging, so we landed up with this spectacular artifact!
Yes, the bright orange object is a foreground star overlapping a much more distant disk galaxy 😃
LSB is another option.
Hmmmm, I don't think it is disturbed, as I cant see anything else interacting with it. Young proto spiral perhaps?
I would say it is a two armed spiral. The arms are wrapping back on themselves so it gives the appearance of a ring.
That is a very long tidal tail!
That is a good one - looks like an E5 #elliptical galaxy to me!
Nice! #overlap
Not a lot of interaction, but certainly gravitational bound. A lot of artifacts, and the image is heavily processed.
Not so sure about the bar,but definite spiral features 😃
@lostlens really? overlap? Interaction is quite obvious. How do you quantify it as being an overlap?
That is an awesome one! 😃
Not so sure, could be a foreground star. Have you had a look at the individual filters?
That happens to me all the time! Lovely smooth E7 ? galaxy at the center.
That is a nice one!
#boxy to boot!
#merger for me!
Sorry - not likely 😕 Just looking at the colour the central galaxy is a lot further. No interaction.
No arc or ring for me 😃 a 2 armed spiral. The arms are folding back on themselves, that is why it looks like a ring 😃
zoomed out image : http://tinyurl.com/qa3cm9o , you might need to click 'get image'' 😃
The blue blobs are areas of star formation.
Wow - I would go with spiral/ disk, 2 arms and yes, there is something unusual. #merger
No worries 😃 And Welcome!
Unlikely to be a merger- no interaction. No other data to support it.
The blue object in the 8 looks like a foreground star.I am inclined to think it is not a merger, but I will have a closer look...
Yes, a foreground star!
I was tempted to go with #irregular - but there is too much symmetry. No ring - spiral arms. Early stage spiral?
#edge_on #round_bulge
stunning #edge_on #no_bulge
It is a cluster - slightly different. Very similar to one of the new official SW candidates that got modelled last year 😃
It is a galaxy - it looks a bit weird as we seem to have a star overlapping in the top right corner.
Not a nebula - a galaxy. Looks like a dwarf to me 😃
I am thinking the same thing- I will need to have a closer look. following
Not a lot of interaction, so I would go for gravitationally bound i.e. a group or cluster
#Merger 😃 The blue areas are star formation triggered by the merge. No gravitational lensing! #no_lens
I am more inclined to go with overlap. I can't see any visible sign of interaction. Also, colour suggests the edge on galaxy is a lot futher
Looks like another galaxy to me 😃 voorwerpies will have more intense colouring.
I am not seeing any lensing in this image - just a gorgeous merger 😃
Even though this isn't a galaxy #ZGOTW 😄
Once again a galaxy and a foreground star 😃
The galaxy at the center has a #bar and a #ring - the bright blue object is a foreground star.
It does look a bit disturbed!
Correct! the object at the center is a galaxy, and the blue object is a star. It only looks very bright because it is so much closer!
You are correct they are all stars, but they only look connected due to line of sight 😃
That green bit looks like an artifact as it is in only one band. The larger blob at 6 is a galaxy. As too wether they are merging - unclear.
I don't think it is a merger per se 😃 We have star formation, possible satellite galaxy to the right. Not an irregular.
The round object is a foreground star, the disk does look somewhat disturbed but the image is very low res - must of been a windy night!
That does not look like an LSB for me 😕 I know SIMBAD says it is one, but I think that is a bit misleading.
It's designation is 2MASX J08072045+0357156 , and it is a smooth / elliptical galaxy 😃
They are satellite galaxies of the larger one at the bottom of the image 😃
@lostlens - you do not need to comment on every image you classify - just the ones you find interesting. Thanks 😃
And Welcome to the Zoo 😄
That does look interesting! Possible #lens candidate for me 😃
Are you talking about the line between the galaxies? I don't think it is a gravitational lens...
They are both galaxies 😃 The bright blue areas are starbursts (areas of intense star formation).
All sorted... some people should not be allowed to drink.
Oh sorry Liz - got distracted. Had to call the police for a situation outside my flat...
Hey Liz, I don't think Els was referring to you 😃
If you like Star Trek - read this 😃 http://talk.galaxyzoo.org/#/boards/BGZ0000002/discussions/DGZ0000w3f
Oh my word - Yes it does! 😄
I am not so sure about boxy 😦
This thread has more information here
Welcome Pin Valentine 😃 That is a foreground star from our own galaxy 😃
Not too sure - I tend too associate polar rings with spiral galaxies, this looks like an elliptical. Scientist?
I would go with #merger - the spiral at the center is very disturbed 😃
A satellite trail 😃 More info here
I would go with overlap, and I am not a professional either 😃
One for Liz's art thread!
No lensing 😃 There is another galaxy just off screen - looks like a tidal tail. (There is also a diffraction spike to the right)
another #boxy bulge!
That's a difficult one - instinct says spiral, but it does have ring features - although I would expect a ring to be smoother.
#NGC 7345
That looks like a foreground star but amazing #boxy bulge!
That is an elliptical galaxy - the bright ball is the core or hub of the galaxy 😄
here it is: http://www.galaxyzooforum.org/index.php?topic=273513.0
Sadly, there is no Spectra available for this star - but there is an excellent archived thread on the old forum to do with White Dwarfs 😃
The colours of the stars are not real, there is a lot of processing that goes on too enhance the images. Have you looked on SIMBAD?
Wow! definately #ZGOTW
I don't think it is a diffuse nebula 😉 More likely an imaging / filter error.
wow,that is one disturbed spiral! Possible flyby or early stage interaction with the galaxy on the right?
Not seeing a lot of blue and no spectra, so I am going to go with no 😃
a planetary nebula 😃 A remnant of a star.
Looks like a low surface brightness (LSB) galaxy #UGC 31
Looks like we have a star (the round object) from our own galaxy overlapping a much more distant galaxy. Info
That is a foreground star from our own galaxy 😃 More info on artifacts here
I am more inclined to think overlap, as there doesn't not appear to be much interaction. Possibly gravitationally bound?
#irregular for me
I would say so 😃 Nice tidal loop!
Supernova - No. Ring - looks like it! 😃 Hint of a #bar as well!
You are correct #artifact caused by over saturation 😃 I am sure I have seen you around before ???
Classifying this image I would say no, looking at the wideview SkyServer image I would say possibly. We need to differentiate btwn the two.
Not really 😃 more about the emissions themselves. I am not a spectra expert - prefer GL modelling. For spectra @budgieye 😃
just classify as a star/artifact - the algorithm gets thrown off by bright objects such as stars.
No worries! There is still loads of spectra available on SkyServer, but sadly not for these galaxies! 😃 I will keep digging...
... from visual observation. I guess I don't need to say this, but Skyserver can sometimes be incorrect 😃
Aahh, I see where you are looking! Very rough estimate, with no spectra to back it up, very unreliable. I do think it is a merger...
top right?
Where about on Skyserver? There are several 'z' values that are not actually redshift values 😕
Are you looking at SkyServer for the redshift?
I think I would go with a spiral - the arms look like they are rounding back on themselves. Looks like we have a bar too 😃
a central bulge 😃
Not edge -on 😦 Nice spiral or disk galaxy 😃
Looking at the different filters, I would say it is more likely to be star formation in spiral arms. #no_lens for me personally.
I would go with #starformation myself!
Another one for the collection #NGC 😃
The white line is a diffraction spike from a star just off screen 😃
I agree it is a spiral galaxy 😃 The compressed objects are foreground stars.
#satellite trail 😃
To the left? That is a diffraction spike from a bright foreground star just off screen 😃
There is some slight discolouration, but I do not think it is lensing. Less apparent on the DR8 images - mmmm.
Hi 😃 Where about are you seeing the arc in the image?
That might of been the case with the UKIDSS images, but we are now back on SDSS. Also no spectra, so not much to suggest AGN. @budgie?
#NGC 5303
It is a foreground star from our own Galaxy 😃 It looks a bit odd as it is quite over exposed.
No, I would not say it is edge on. Looks like a normal head on spiral.
Yes, it is a foreground star from our own galaxy 😃
An #irregular galaxy with star bursts 😃
That is a foreground star 😃
It is a foreground star 😃
stars 😃
There are a lot of stars overlapping the galaxy. Normal 2 armed spiral for me 😃
gorgeous #merger!
Not likely 😃 The dome would of been commanded to close before the sun rose. More likely there was a problem with one of the filters.
I don't think so - we do seem to have interaction between the top blue satellite galaxy and the central one... anyone else?
No, this is a lovely elliptical galaxy. Stars tend to be more defined - galaxies a bit fuzzy 😃
Yes 😃 a foreground star!
Just a very disturbed night when the observing was done - hence all the background noise!
We want your classification, no matter how incorrect! We learn a lot from every click done!
Unless you are meaning the M40 highway? A big resounding...No.
Nope.
@planetaryscience - thought you had moved onto greener pastures, after all the PM's I got last week 😃
Line of sight 😃 Same effect when you use a camera.
Why don't you post it in the Art thread in Chat! 😃
That is a nice one! #NGC
It is an #artifact caused by a foreground star.
Yes - that is a star up top! 😃
@flyaway - no worries!
You can read more about them here
The top and right objects are both foreground stars from our own galaxy 😃 The green/red/blue object at the bottom is a asteroid!
#bar #spiral possible #inner_ring
@flyaway - Hi and welcome 😃 What object are you referring too?
#UGC 123
It is a galaxy 😃 I would go with a low surface brightness (LSB), irregular galaxy. Does have a spiral pattern of sorts...
Not a super nova - but a foreground star! 😃
That's right! Two foreground stars 😃
It is a galaxy directly at the center, with a foreground star to the lower left of it 😃
#NGC 0102
Wow - with a #bar as well 😃
They all look like foreground stars 😃 Have you read this thread: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
I only see a single spiral galaxy 😕
The bright blue bits in the arms are regions of intense star formation or #star_bursts
#UGC 01070
Yes, I would agree the galaxy at the center has #spiral features 😃
Hi @mindstate55 - please only classify the object at the center 😃 Thanks!
certainly a #bar, possible #ring
Yes, they are all #stars 😃
I think I agree with @C_cld - shell galaxy?
We really do need an Art thread!
No 😃 It is definitely a galaxy - looking at the colour, fairly young. Looks like we have star formation going on.
Nice one! Congrats 😄
It depends on what project you post on... we are specifically looking for a galaxy 😃 Hence galaxy of the week 😃
we are using the hashtag #ZGOTW over here
See this thread: ZGOTW?
I would certainly say it has spiral features!
That is a foreground star 😃 Remember to only classify the object directly at the center - this case a diffraction spike from the star.
No lensing for me - looks like a spiral arm 😃 The blue discolouration is star formation.
Yes, that is a #diffraction_spike from a foreground star off screen 😃
I would say #spiral - not very well defined, but certainly too many features for it to be an elliptical. Agree with #odd 😃
... What is ZGOTW?
I would go for #boxy as well 😃
#ZGOTW for me!
I don't think so 😕 - I would still classify it as smooth / elliptical
Most galaxies do contain black holes - but we would not be able to see them on these images 😃
Another galaxy 😃
I would go with #overlap - you can see the dust lane extending over the galaxy on the right.
You can also add comments to a individual object within a collection 😃 Very Useful!
Yes - you can view it in the collection. By the way you can follow a collection, so it is easier to find!
lol 😃 No sadly just a foreground star!
Unlikely to be gravitational lensing. I am thinking star formation - spiral features, but... - very interesting galaxy. I will flag it up!
Image is very fuzzy - my vote is a foreground star or satellite perhaps?
#bar #spiral #star_forming #stunning 😃
Does this work better?
A #ZGOTW for me!
... more info here
lol - click on the link in the comment 😃 It was a rhetorical question - but I think I might have to change the wording!
Wow - that is a stunner!
Good to see you Claude 😃
The dark spot? That is an artifact caused by over exposure / saturation.
That's right! A foreground star 😃
But, here on talk you can ask about anything in the image!
The orange one on the right? That is a foreground star 😃 Always remember to only classify the object at the center 😃
...possibly a foreground star?
A smooth or elliptical galaxy 😃 There is something a bit odd on the right hand side - also in the SkyServer image...
lol 😄 All foreground star from our own galaxy. The SkyServer image is pretty awesome!
What is ZGOTW?
I think I might ask @mrniaboc if this could be the galaxy of the week 😄
Another WOW 😄
😄 I never this many gorgeous galaxies to classify in a day! What is your secret 😉
WOW - absolutely stunning!
It is a star cluster, but the object directly at the center is the faint orange star next to it 😃
Hi and Welcome 😃 Remember to only classify the image directly at the center, in this case the smooth or elliptical galaxy 😃
Yes:-) It is a star from our own galaxy!
The really bright object is a foreground star 😃
Wow! A piece of art 😄
The orange object is a foreground star, so it is by line of sight that it looks connected to the galaxy 😃
Artifacts 😃 Something went wrong with the imaging (in particular the blue filter) and this was the result.
Not a merger 😃 A stunning #overlap of a foreground #spiral and a much more distant #edge_on. #dust_lane in the edge on galaxy 😃
No it is not a Hanny's voorwerp 😃 #star_formation in a #irregular galaxy.
2 answers for the price of one 😄
They are both foreground stars 😃 The algorithm that selects the objects to classify sometimes gets confused with bright foreground stars.
All foreground stars - have you read the link I posted in your previous comment? 😃
They are artifacts 😃 Have you read this thread: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
This is a foreground star from our own galaxy. The imaging went a bit wrong and this amazing artefact was created 😃
But, we do seem to have some satellite galaxies. The artifacts on the right hand side of the objects are not helping either 😃
Difficult to tell as the image is really fuzzy - my gut instinct says no ,as I am not seeing many signs of strong interaction.
Not a cloud - a galaxy 😃 From the shape I would go with a smooth or elliptical galaxy.
I would say yes, Dave 😃
You are right - star formation regions 😃 Seems to have a slight #bar and looks like an #irregular galaxy
Looked at it in a bit more detail in the DR8 SkyServer image, will get a scientist to have a closer look 😃
I would go with #spiral galaxy. A very loose limbed spiral 😄
It is a loose limbed spiral galaxy 😃 Remember to only classify the object in the center, but it's okay to discuss it here 😃
Does not appear to be an artifact either. Visible in several filters #curious
A fuzzy, non-descript galaxy 😃 We seem to be getting a lot of them today!
It is galaxy 😃 Small,not many stars - I would go with #dwarf_galaxy myself, but it also be classified as an irregular.
Nice! Looks like we have some interaction going on between the two 😃
Yes 😃 it looks like a foreground star overlapping a galaxy. All the stars in the image are displaying similar artifacts.
There is clear interaction between the two galaxies #merger for me
Its a bit fuzzy and non-de-script, but it is still a galaxy 😃
Possibly a dwarf galaxy? Not much info on NED or SIMBAD 😃
Really difficult to tell - I am not entirely convinced the smaller object is a galaxy.
Ignoring the obvious satellite trail, I would personally say star 😃
It is:-) Aren't they spectacular!
Wow! - that is a stunning one 😃
A artifiact cause by a bright foreground star off screen 😃
Yes - I would go with foreground stars 😃
The blue object on the right is in fact a foreground star 😃 Always remember to only classify the central object - Thanks!
An #artifact caused by bad imaging. It is in fact a foreground star.
What a fuzzy image! It could also be a foreground object overlapping the galaxy - difficult to tell. Sorry 😃
Looks like it could be a satellite galaxy 😃 It is quite common for larger galaxies to have smaller companion galaxies.
Awesome #overlap #NGC6365B
Looks like we have a #boxy_bulge 😃 Stunning!
Its a artifact, we get this type when we reach the end of data set 😃
No worries! Have fun classifying 😃
Gorgeous #merger 😃 Look at those #tidal_tails
Yes, that#s right 😃 #satellite trail
Looks very disturbed - most likely due to interaction. The central galaxy also has an interesting spectra - possible AGN?
I would say it is #barred with #spiral features 😃
Looks like a satellite / asteroid trail that has been cleaned up 😃
Optical artifacts from a bright foreground star off screen 😃
#barred as well 😃 Stunning!
Gorgeous #barred #spiral with clumps of #star_formation
That bright object is a foreground star, the color and spikes are all artifacts. Have a read of this
I don't see any signs of a merger, possibly a proto spiral? We can see some faint spiral features.
Looks like the tracking malfunctioned during the green filter - those streak are all foreground stars!
Looks like a possible #polar_ring
Hmmm, not seeing much signs of a bar - but you are correct with #spiral 😃
That is seriously disturbed! Possible #bar like structure as well.
They are foreground star from our own galaxy 😃 Remember to only classify the central object.
I would go with #stars 😃
2/2 galaxy with a smaller satellite galaxy. Very Fuzzy image, so classifying it could not be easy 😃
1/2 Ignore the long stream - it is a diffraction spike from a bright star off screen. The 'big bulge' looks like an elliptical (or smooth)
The bright white /green / blue / red objects? They are both foreground stars 😃 remember to only classify the object in the center.
Foreground stars, again 😃 Remember to only classify the central object, but on talk it is OK to talk about the rest of the image 😃
And you are right! 😃
That is an artifact, if we look at the larger image their are a few of them running through the field, in a line 😃
They are all foreground #stars from our own galaxy 😃
I would go with #overlap 😃 Rule of the thumb. Blue galaxies - close, red/orange galaxies - far. SkyServer think the orange obj is a star
A disturbed spiral, with star forming regions. No merging for me 😃
Well done! Edge-on disk (or spiral) galaxy with a round bulge 😃
Looks like a foreground star - we have several objects scattered around the image 😃
Only classify the object directly at the center, in this case the orange elliptical 😃
The asteroid is not within frame of this image 😃 You might send some volunteers on a wild goose chase trying to find it...
Sorry - I don't see anything either 😦
Look at the SkyServer image 😃 Looks like a small part of a larger galaxy cluster!
We try not to use acronyms in the comments section - we have a lot of newbies.They will not know what you are talking about 😃
I would go with #barred #spiral - there are more spiral features than a true ring 😃
Edge on galaxies tend to have pointy ends, cigar shaped ellipticals have more rounded tips 😃 This one looks pointed to me!
Looking at the image I am inclined to say foreground star - there are several similar objects in the image.
Sorry - no sing of a ring. A 2-armed spiral #no_ring
#barred #spiral with a #dust_lane - no rings 😃
I would go with artifact - they all look like foreground stars
Looks like it! nice catch!
I don't think it is a merger - The orange object is more likely to be a foreground star 😃
WOW - that is a stunning one 😃 #bar and #ring for me too!
I agree with disk at the center, but it looks like the object to the right is a foreground star.
Yes, a disk or edge on galaxy. Looks like we might have a bit of a dustlane 😃
I would go with #merger on this one 😃
That is a satellite trail 😃
That does look disturbed - you can see a star trail off to the left. The image also looks a bit misaligned.
That's an artifact. The foreground star tend to overwhelm the telescope and create some interesting artifacts!
Looks like something went wrong with the imaging - particularly the red filter.
Not an artifact. Satellite galaxy perhaps? The image is very low resolution,so without spectra,it is going to be difficult to tell.
Very blurry image, but I think I will go with overlap not merger. Not many signs of interaction.
Foreground stars - as the comments below suggest 😃
Sadly, they are all foreground stars. Sometimes the images we classify do not contain any galaxies.
Not a galaxy, but a foreground star 😃 The colours are artifacts caused by over exposure.
And, you would be right! Star bursts 😃
It does look somewhat irregular 😃 The blue clumps are regions of intense star formation, and we have a slight spiral structure.
It is a satellite trail - they move so quickly across the sky they only get captured in a single filter 😃
An artifact. This is in fact a foreground star from our own galaxy. Something went wrong with the imaging 😃
Only ever classify the object at the center! The object in the top right is a foreground star 😃
Hmm,they all look like foreground stars to me - I would of classified them as star / artifact 😃
You would be right! All artifacts caused by foreground stars and over exposure 😃
You are looking at the image directly at the center, in this case the orange blob to the right of the red line. Star / Artifact for me 😃
An #artifact caused by a foreground star and problems with imaging 😃
No lensing - just similar looking elliptical galaxies. Not much interaction between them, gravitationally bound as opposed to merging.
That right! The blue area are regions of intense star formation 😃
Yes, it is planetary nebula - more info in the comments below.
Both the blue and green stripes are satellite trails - each got captured at different times in different filters.
It certainly has spiral features, so I would classify it as such 😃
Not so sure it is disturbed - think we have the beginnings of a #bar
#starforming
No 😃 The object on the left is a foreground star from our own galaxy 😃
Only classify the object at the center 😃 In this case the star
No worries 😄
I would go with #spiral galaxy with #bar 😃
Diffraction spikes from a bright star off screen 😃
I can't find many signs of interaction, so#overlap for me
Remember to only classify the central object 😃 I would of gone with star/artifact in this case.
I am more likely to go with foreground star.
For me optical illusion - line of sight. If you look at the SkyServer image, it looks like they are in a star cluster.
I think they are more likely to be satellite galaxies - but the image is really fuzzy.
#stars
That is correct - all foreground stars 😃
All the objects in this image are foreground stars- looks like a star cluster in the SkyServer image.
That object is a foreground star from our own galaxy 😃 It is just by line of sight that makes it look like it is connected to the galaxy.
That's right - a satellite trail 😃
Have you had a read of this thread ? http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh 😃
It is not unusual for there to be areas of intense star formation at the end of bars - this is an excellent example 😃
It is an #artifact - something went wrong with the imaging and this is the result 😃
I thinks the 2 stars are unrelated to each other 😃
It looks like 3 foreground star to me 😃
Looks like a overlap of two galaxies 😃 We have the elliptical at the centre and a much more distant galaxy on the right.
Wow - awesome nebula!
This thread is a nice summary of the different types of artifacts: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
@planteryscience - that is not the object we have to classify 😃 The central object looks like a star/s to me 😃
I would go with 2 armed loose spiral. The other blobs are foreground stars overlapping the galaxy.
or a flyby- that would explain the starbursts and distortion in the lower galaxy.
Looks like we have interaction between the 2 galaxies - very early stage merger 😃
One 😃 The orange blob at the bottom is a foreground star.
nice one 😃 #boxy_bulge #x_bulge
Looks more like a spiral arm 😃 Galaxies of this size do not have the mass too cause strong gravitational lensing 😃 But keep looking!
The tiny smudge on the right of the galaxy? I would go for satellite galaxy 😃 Gravitationly bound, so merger would not be far off!
They certainly look disturbed - fly by perhaps?
Lol - looks like they are interacting, Early stage merger perhaps? 😃
Very fuzzy - but looking at the blue color in the top galaxy, suggests star formation - so I would go with yes 😃
#cropped image
ä¸€ä¸ªæ´»è·ƒæ˜Ÿç³»æ ¸çš„è¿¹è±¡ - æ¤åœ†æ˜Ÿç³»ã€‚ -thank you Google 😃
That is a foreground star - it looks like we had imaging problems, so it looks a bit odd.
#irregular #starforming
#boxy_bulge #dustlane #edge_on #x_bulge
A satellite trail 😃 http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
The resolution is really bad,so we would not be able to tell.
The dot is an artifact - the core of the galaxy is quite bright, so it was over exposed.
This image is quite fuzzy, but the object to the bottom left is a foreground star, so no merger 😃
You would be correct - no signs of interaction, so a chance alignment 😃
The bright object on the right? That is a foreground star from our own galaxy 😃 same as the orange dot overlapping the galaxy.
Not an exploding star 😃 Something went wrong with the imaging, and a foreground star turned into this lovely artifact.
No, I am thinking it could be a very fuzzy foreground star in front of the galaxy.
Yes, it is an error 😃 It looks like the telescope moved when the green filter image was taken. Sorry! It happens from time to time 😃
Hi @Andrewgalaxy - always remember to only classify the object at the center 😃
There was no film left in the camera 😃 It is the end of particular stripe.
Artifacts caused by a bright foreground star just off screen to the left 😃
Answer below 😃
Foreground stars from our own galaxy 😃 More info here: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
and you would be correct! 😃
Foreground stars from our own galaxy 😃 Looks like something went a bit wrong with the green filter, but a really nice star cluster
In this case it look like a foreground star 😃 and SkyServer confirms it 😃
Answer is in the comments previously left below 😃
Satellite Trail 😃 Have you read the comments below? Your question might be answered already 😃
Diffraction spikes from a star off screen. Have you read this: http://tinyurl.com/GZartifacts- it will answer a lot of your questions 😃
I see what you mean 😃 Instead of being totally smooth, we have some spiral features - very fuzzy, but certainly features.
You are only looking at the object at the center 😃
Satellite trails 😃 Have a read of this thread: http://tinyurl.com/GZartifacts
They are artifacts 😃 http://tinyurl.com/GZartifacts
No all galaxies have cores / hubs at the center 😃 This looks like a dwarf galaxy.
The pink middle is an artifact - as this is a foreground star, the brightness has caused over saturation,hence the artifact.
No merger - this is a star 😃
@maxrebo101 - you are right, no bulge! The clumps are area of dense star formation.
@dagueerrotype - Yes! Always classify the object at the center, Disregard all other objects 😃
Yes 😃 It is an #irregular galaxy with #starbursts (areas of intense star formation) - nice!
Difficult to tell, my gut instinct says artifact.
I would say that looks like a #merger 😃 Nice interaction!
I would go with a late stage merger, the second core could be the object at 11, embedded in the central galaxy.
This is an artifact - sorry! Something went very wrong with the imaging / processing 😦
I think we have 2 foreground stars overlapping a edge on galaxy. The stars would account for the double bulge 😃 Anyone else?
I am also seeing a faint spiral features - nice catch!
An #irregular galaxy with a slight #bar - awesome 😃
All look like local stars, have you tried looking at the SkyServer image? Looks like we might be in the middle of a star cluster 😃
possible #polar_ring? not as clear cut as other examples, but still worth a tag.
The blue object is a star. I am more impressed by the #edge_on galaxy with a #dustlane and a somewhat #boxy #bulge at the center 😃
More info here: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
It is a foreground star from our own galaxy. The brightness causes all of these weird artifacts 😃
I would go with multiple galaxy / star overlap. It is possible from looking at the tidal debris there is also a merger in the mix.
Foreground star from our own galaxy, over saturation causes the odd artifacts.
Only classify the object at the center - Thanks! 😃
The blue clumps in the arms are areas of intense star formation. I would go with more than 2 arms, but definitely #barred
Remember only to classify the object at the center 😃 As yes, it is possible that the galaxies at the center are merging.
Actually two elliptical galaxies 😃
Close to the central galaxy?
They three bright objects are foreground stars from our own galaxy. I am sure it will not be too long until you find your first merger 😃
Not seeing much interaction between the two - more likely an overlap, or a flyby.
A nebula - awesome! 😃 If you look at the comments below you will find a link to the zoomed out image.
Difficult to say, the image is very fuzzy. There does appear to be faint signs of interaction between the 2 orange ellipticals. No Spectra.
A bright foreground star just off screen to the left 😃 We have some diffraction spikes and arcs radiating from it.
I would agree with you #barred #spiral 😃
It is a foreground star 😃 Remember to only classify the object in the center - in this case the tiny orange blob (star? )
They all look like foreground stars 😃
A satellite trail 😃 More info in this thread: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
Artifacts 😃 When the image in the green filter was taken, the tracking was not working correctly. The green streaks are foreground stars.
I would go with 5 separate stars - you would be amazed of the shapes that come about, through sheer chance alignment 😃
I do not think it is a merger - there is no interaction between the galaxies. Nice #overlap 😃
Not a nebula - a foreground star from our own galaxy. The weird blue colour and shape are down to oversaturation 😃 More comments below...
Looks like an asteroid, but when the image was stacked the red filter was slightly misaligned.
You are correct - Star 😃
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=148.42666248&dec=55.75879656 and click on 'Get Image' to see the star 😃
That is a foreground star off screen to the right 😃 You can see the diffractions spikes.
Just to add - only ever classify the object at the center - Thanks! 😃
The central galaxy certainly has spiral features, and a barely their hub 😃 The bright object is a foreground star from our own galaxy.
Wow, that is a stunning one! #IC_2098
It looks like an artifact - you can see similar discolouration in the foreground stars. Imaging / stacking error.
No dust lane here 😃 An awesome #barred #2_arm #spiral
I would go with merging / interacting galaxies - no lensing here 😃
Wow - look at that interaction! #NGC_5258 #NGC_5257
Satellites move really quickly, so they only get captured in a single filter
I am not so sure...I will have to have a closer look, but it is some what odd.
Not a nebula - a galaxy (or two) 😃
...also no interaction btwn the 2 galaxies, so we can exclude that the star formation in the smaller galaxy is triggered by merging.
I would go with #overlap - just looking at the colour of the galaxies suggests the central galaxy is a lot further away...
I would go with stars, but the alignment is somewhat uncanny.
Not a merger or a black hole 😃 Loads of star formation / star bursts
They are both foreground stars from our own galaxy 😃
That is a stunning one!
@lostlens: also to quote NED - "Interacting pair with NGC 4676A at 0.6 arcmin." #merger
The black dot is an artifact - the rest of the galaxy is awesome! It is a well documented polar ring galaxy 😃
Not a edge-on galaxy or a ring. As you said it is very fuzzy, so that makes it difficult to classify. Also displays spiral features...
It could refer to a cluster of stars, or a cluster of galaxies. Groups or pairing of a particular object.
The red colour is caused by a bright foreground star off screen. It is difficult to tell if we have a galaxy at the center.
A satellite trail 😃 They move so fast, they only get captured in a single filter.
In this case I would say no, there is a hub and a spiral pattern. Dwarf galaies tend to be very non-de script.
they are artefacts caused by a bright star off screen
are you referring to the dark line just to the lower right of the core / hub?
We only have 1 redshift and it suggests star formation, We do know that starbursts can be triggered with a merger. I would go with #merger
Hi @lobeck - it does look like we have 2 cores in the central galaxy, but I will need a closer look... galaxy upper left looks unconnected
#UGC04434 Mentioned in "KISO survey for ultraviolet-excess galaxies" (see NED for more details)
Looks like a dwarf galaxy. Another possibility is a low surface brightness (LSB) galaxy
No ring, looks like a very loose spiral or edge on.
You can't fix an image after it is taken 😃 You can enhance it, tweak it, but if it is corrupted there is nothing you can do about it.
??? please explain @0796441272
Hmmmm, it could be, as there does appear to be a galaxy off screen, but there is also a lot of background noise, and also no spectra.
The image is very fuzzy, so it could also be very tightly wound spiral arms 😃
That's a stunning galaxy! Possible inner and outer rings - nice indeed 😃
It does look a bit disturbed, but as the image is so fuzzy, it is difficult to say for sure!
No spectra, so we would not be able to say for sure. In the meantime nice #barred #ring galaxy 😃
Tidal tails 😃 Nice interacting galaxies!
It is only by line of sight that they look so close together 😃
At the center we have an edge on galaxy, to the left a foreground star 😃
Something went wrong with the imaging, causing these artifacts.
#elliptical #smooth
No, that is in fact a nice example of a #edge_on galaxy 😃
And you would be wrong 😃 It is in fact a galaxy...
No - a foreground star from our own galaxy the milky way.
I would say that they are more likely gravitationally bound than merging. With mergers we would see interaction between the galaxies 😃
Looking at SkyServer and NED I would go with a cluster of galaxies - more impressive if you zoom out 😃
That appears to be the 'z magnitude of the galaxies, not the z redshift (they are not the same thing). Let me have a look around 😃
I would say single object - the colour plates are misaligned. If you have a look on SkyServer it is happening to all objects in the field.
I am not so sure they are merging - perhaps gravitationally bound?
Always classify the object in the center 😃 In this case a foreground star. The black blob in the lower galaxy is a artifact.
There is discolouration in the dr8 image, where we would expect to see the counter image...
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=183.03690026&dec=13.79253341
I am somewhat sceptical #no_lens . If we look at the DR8 image, we can see a similar 'arc' extending in the opposite direction. #curious.
That is a foreground star 😃 Remember to only classify the object at the center. Stunning #bar
Actually looking at it closer it is even more confusing...Scientist?
That is odd. Comet? No. most likely overlap.
WOW, that is a stunner! #barred #spiral
I would go with #spiral 😃
I do not think it is a post-merge,but it is some what odd - looks like a bar gone wrong. Will try to get second opinion.
#sattelite trail
Looks like stars for me 😃
What axis are you basing that on? and hi @planertryscience 😃
No 😃 3 foreground star from our own galaxy.
😃 Read below ...
snap
Both upper and lower looks like arms, The bright place, looks like a star burst
It is an artefact, caused by a star off screen.
I am going to have a look on SkyServer...have you seen this: http://talk.galaxyzoo.org/#/boards/BGZ0000005/discussions/DGZ0000lv2
And you would be right 😃 Amazing!
...lower and to the left. So we are then left with a 2 armed, loose, spiral galaxy ,with star formation in the arms 😃
Not so strange when you analyse it bit by bit 😃 the blue object at the top is a foreground star. So is the yellow object slightly...
They are all stars- the algorithm sometimes gets confused between foreground stars and fainter galaxies. Read below 😃
I would say yes 😃
Hi @mercuryb 😃 ummmm, why are you expecting them to reach the side? I can only give a accurate answer, if I know the actual question 😃
I am thinking all the object here are stars - fortunately for us computers are not that good at classifying!
Have you had a look at this thread - it is really helpful for newbies 😃 http://tinyurl.com/pbo34r2
They are not galaxies, but rather foreground stars. Look like something went wrong with the imaging of that particular field.
Hi and welcome @lobeck 😃 Follow your instincts! There are no wrong answers. Thinking foreground star in this case.
No visible interaction either,more likely overlap.
It looks like a disturbed edge-on, No redshift, so it is difficult to tell if it is connected with the central galaxy.
I would go with #star, if it were an asteroid we would see more movement, and the 3 filters would be more apparent.
After looking at SkyServer, I would go with a cluster of galaxies. No spectra and not much further info.
No- they look like galaxies. I will have a closer look.
#NGC_7595
A very disturbed galaxy, with foreground stars overlapping it.
That is a foreground star from our own galaxy 😃
@cateye1012 The galaxies are in the process of merging, so the 'veil' are millions of stars that are ripped away in a tidal tail.
We have spiral features in the galaxy,so those would be very fuzzy arms.
They are regions of intense star formation or star bursts 😃
#SHOC_142
For those so inclined: http://arxiv.org/pdf/astro-ph/0404133v2.pdf
NED has it listed as a SHOC (SDSS H II galaxies with Oxygen abundances Catalog) galaxy... looking for more info
That is a odd one! Not a foreground star, starburst perhaps? Trying to work out if it is a single object or 2...
Your first guess was correct! #star 😃
Hi @gbollmann remember to only classify the one at the center 😃 The other one will come up in another image 😃
Foreground star - a processing error 😃
They are satellite trails 😃
I don't think it is disturbed :- ) It looks like we have a plane / satellite trail going directly over the galaxy.
I have taken the opportunity to create the discussion. See Right -->
This is the recents tab and not the discussion board after all 😃 If you would like to argue about this, take it there.
@zutopian with all respect, we have both acknowledged that it is possible, and that it will get look at further. Case closed.
... it is very unlikely we would see lensing of this nature, this visible. I am sure it will get further analysed 😃
And everyone is entitled to their opinions 😃 I would add that even if this is a E7 (or similar) elliptical galaxy...
Jinx 😃
That is not a star - but rather a star burst 😃 Star Bursts are regions of intense star formation. There is are several in this galaxy.
or we have a bar forming at the center? Also some spiral features.
There is a lot of background noise in this image so I would go with artifact
I am not seeing any lensing, are you referring to the dots around the central galaxy, or the blue smudge at 4?
Only classify the central object 😃 In this case a stunning #edge_on
That is a satellite trail, they move really fast so they only get captured in a single filter.
They are foreground stars, but something went wrong with the imaging
awesome #merger
Amazing #merger
Then again it could be an overlap. Skyserver was no help, but the star to the left has similar characteristics to the top left galaxy.
Without going to SkyServer, I would say no. The colour of the galaxy at 11 indicates it is a lot further away than the centre galaxy.
I think it is the same galaxy, just somewhat irregular. Odd indeed. 😃
WOW! talk about a merger!
I think you are right - foreground star 😃
Definitely a #merger of the two central galaxies. Not so sure about the one on the left.
I would say yes 😃 Nice!
I will have a look, but stunning #bar in the meantime 😃
Looks like a polar ring - I would love to have a scientists opinion 😃
That does not prove anything. Why do you think this is a overlap?
The claim being that this is an overlap... just clarifying.
@lostlens unless you can back up your claim, consider this a final warning.
You should have a look at it on SkyServer - really quite impressive 😃
@lostlens overlap why? 😃
You are right 😃 They are both stars from our own galaxy!
I would say that is a satellite galaxy of the larger central galaxy 😃
Perhaps you should start a discussion?
@lostlens there is clearly interaction going on, so it is not a overlap. We would love to hear your reasoning as to why it is a overlap 😃
Loads of interaction between 3 galaxies - http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=83.22151822&dec=-7.77571724
Unlikely 😃 More likely the result of a flyby. Will have a closer look on SkyServer...
No lens for me 😃 It looks more like noise
we also have several foreground stars... Hope this helps, and we welcome more questions 😃
I would go with a #barred #spiral. Loose arms with a big bulge 😃 But that is just me - we want your opinion 😃
I am not seeing many signs of interaction - perhaps gravitationally bound rather than merger?
That is a stunner!
I would agree 😃
No spectra 😦 So we would not be able to say for sure, but it does have a well defined bright core, so it is possible 😃
#NGC0575 #UGC01081
Has a lovely #bar as well 😃
No lensing for me. you are referring to the smudge at the bottom of the elliptical galaxy?
Artifacts - something went wrong with the imaging 😦
#stars loads of them 😃
Hi @nesMC and welcome. What object are you referring too? The blue object @ 8 or the center galaxy?
I would go with star for the object at 9 😃
Hmmm - are you talking about the black specks at 1 and 8 from the centre of the galaxy?
Unfortunately we do not have a spectra on the galaxy, so it would be impossible to say yes or no. Visually I would go with unlikely.
Wow! That is a stunning one 😃
@diamondmc the orange object in the 7 of the larger spiral? That is another galaxy. In this case they are overlapping 😃
#tidal_bridge perhaps?
Slight #bar at the centre #doublering
I am inclined to think overlap 😃 The pink / orange object certainly looks like it is a foreground star - but I had to look more than twice
😃 Also, it will have no apparent spiral pattern - just irregular - hence the name.
.. looking at the colour of these ones, they are orange and fairly conform, therefore a lot older. Hope this helps, and we love questions!
No, irregular galaxies tend to be lower in the chain of galaxy morphology. They are young,blue and irregular in shape...
Not blue or irregular enough to be a irregular galaxy 😃 I think merger is more likely
The blueish colour distortion in the lower left arm is due to star formation triggered by interaction. As @ElisabethB said - a #merger 😃
Also, what object did you think was being lensed? 😃
Hi @MartinTheK - I am not seeing any spectra associated with this object, therefore no redshift 😃 Do you have a link?
Looks like the computer got confused by the diffraction spike, would of classified it as star/artifact.
That is a satellite trail 😃 More info here: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
I would say we have a foreground star overlapping a much more distant galaxy 😃
I think they are still in the process of merging, nice starbursts in the arms
At the bottom of the image? or the top right of the central galaxy?
The 'arc' is in fact star formation being triggered by the 2 galaxies at the centre merging 😃
It looks like a star / galaxy overlap 😃
I am not seeing any apparent signs of lensing. What object are you referring to? So I can have a closer look.
Looks like we have some dust - nice!
There is clear interaction - #merger for me.
I would of gone with star /artifact. All foreground stars from our own galaxy.
#merger for me. Possible bow waves at 2 on the off centre galaxy?
The orange one? 😃
Hmmm, I would go with edge-on, the splodge at 6'ish is possibly a satellite galaxy? Really difficult to tell.
also appears to have a nice #bar 😃
I would go with merger.
Most of the objects are foreground stars. Always remember to only classify the object at the center.
I would say no. Spiral arms tightly wound back on themselves instead.
A satellite 😉
overlap for me.
Diffraction spike from a star off screen 😃
Welcome @animatus 😃 awesome merger!
@Nakedeye2 - not likely 😃
Most likely a foreground star overlapping a much futher galaxy 😃
They are both foreground stars - remember to only classify the object at the center!
I would go with barred spiral - but it is your opinion we really want to know about! 😃
That is a satellite trail 😃 More info here
#NGC_7729
It looks like a proto-spiral. A young spiral galaxy with loads of star formation, that still needs to settle down into a classic spiral.
Artifact - imaging / processing error.
No lensing - a spiral arm 😃
It is a sattelite trail, for more info look Here
That is an artifact, for more info look Here
Artifacts - caused by bad imaging / processing
Satellite trail 😃 They move so fast they only get captured in 1 filter.
I would say they are both foreground stars 😃
Artifacts caused by imaging problems.
Artifacts caused by imaging problems, for more info look Here
Those are spiral arms wrapped around the galaxy. Not unusual for arms to have a different color than the core / hub of the galaxy 😃
You can get gravitationally bound galaxies, but the dynamics is different from those of binary stars.
I wish! 😃 Those are diffraction spikes and arcs around a bright foreground star. The amazing artifacts are caused by over saturation.
It looks like a foreground star from our own galaxy 😃
Something went wrong with the imaging! Look here for more information on the different types of artifacts
The 2 objects on the left are foreground stars, and the object in the center is a distant galaxy!
All stars from our own galaxy - the lovely colors are artifacts caused by saturation.More info here
All the objects in this image have similar artifacts - looks like something went wrong with the imaging!
Looks like a merger, the second galaxy appears to be the white blob at 6.
That's a #nebula! For a clearer view click on link: http://tinyurl.com/p3zjxyw
No merger for me - the 2 objects to the right are foreground stars!
Remember to only classify the object at the center! In this case the orange elliptical (smooth) galaxy.
That is a satellite trail 😃. More info here
Not so sure of it being an AGN 😃 AGN's are not very common - most likely just a bright galactic core.
That is a foreground star, for more info look Here
No merging - the objects on the left and right are both foreground star, and I am not convinced the object at the center is a galaxy.
The bottom object is a star from our own galaxy - the milky way. A lot closer than the spiral galaxy at the center 😃
The edge on at 7 or the orange dot on the right?
wow - that is an odd one! A very disturbed galaxy - sadly no spectra 😦
Something went very wrong with the imaging - look here for more info on artifacts.
You are correct! 😃
I would say it is a bit too irregular to be an elliptical, there is also a faint spiral pattern and bar.
I would go with artifact - looking at the SkyServer image, other galaxies / stars in the vicinity have the similar effect.
No lensing for me - 2 blue foreground stars in front of a somewhat disturbed spiral.
No, it is a cluster of galaxies 😃
Only classify the one directly at the center, in this case the orange object. Not entirely convinced it is a galaxy!
I would say we have a foreground star just to the right of the hub of the galaxy.
Yes 😃 Only the one/s directly at the center!
They are foreground stars from our own galaxy 😃
They are foreground stars from our own galaxy. It is just by line of sight that they look part of the distant galaxy.
It is a young galaxy with loads of star formation going on 😃
This is an over exposed star from our own galaxy, for more info look Here
No :- ) it is a cluster of foreground stars from our own galaxy.
The clumps are areas of star formation in the spiral arms.
No 😃 a satellite trail
Lyle?
just different orientation...
No lensing - same as this image from UKIDSS AGZ0006hsq
Another example of SkyServer being confused - 2 stars overlapping. The UKIDSS survey is over, so I think we are back to old SDSS images.
Thank you 😃 Will look it up more in the morning - bedtime for me!
At the core? or else where in the image?
Although we only have the redshift of left galaxy, Visible interaction is still apparent. Interested to hear why you think differently...
You are right - foreground stars from the milky way 😃
No quasar - elliptical galaxy.
That is a foreground star.
Read comments below... sadly not.
No, no quasar - just a elliptical galaxy. Sorry 😃
If that wasn't flagged as a star, I would of investigated it further. That is a classic cusp arrangement for a GL.
and please not delete your previous comment and repost it 😃 Consider this a warning.
I am sure that there are people that would appreciate knowing 😃
@lostlens - can you please state your reasons as to why this is an overlap and not a merger? Thank you 😃
The bright objects at the top are foreground stars 😃 Can't see any signs of merging with regards to the central galaxy itself.
The bright multi - coloured object is a foreground star 😃 More info here
No gravitational lensing - they are both stars 😃
Difficult to tell what object is at the center as it has been cropped, but you are right it is that object. Looks like a foreground star...
#no_lens - That is an artifact, for more info look Here 😃
It is a foreground star 😃 See the older comments below yours 😃
collisional ring galaxy?
Almost looks like a #hoag object if you take the angle into account. edit: would of expected it to be less disturbed if that was the case.
No merger - something went very wrong with the filters!
Yes - it is most certainly a galaxy 😃
It is not real - it is a artifact that was generated during imaging or processing.More info here
That blue ring / dark spot at the center is an artifact, caused by the brightness of the galaxy.
Nice #boxy_bulge #X_bulge
That is a #bar and it only looks a bit odd because of the angle we are viewing the galaxy 😃
#barred #2_armed #spiral
A mixture of foreground stars and clumps of star formation in the spiral arms of the galaxy.
The bright blue object is a foreground star from our own galaxy - The Milky Way,more info Here 😃
The UKIDSS infrared images are more difficult to classify, but just try your best 😃 I would say this one has a faint spiral pattern.
It is a sattelite trail - for more info look Here
That is a foreground star from our own galaxy - for more info look Here
It is background noise in the image 😃
Look in the comments below 😃
A foreground star from our own galaxy 😃 More info here
Lol - I knew it reminded me of something!
The bright spot is a foreground star from our own galaxy. Is the gap you are refering too at the bottom? If so it is an illusion 😃
There is no such thing as right or wrong - we want to know how you interpreted the object 😃 As for arms, difficult to tell - v.fuzzy!
That is an artifact - it was caused by a imaging / processing error - Sorry!
No worries - we are here to help 😃
...- it is too close and too light weight, to cause that type of gravitational lensing.
I would go with overlap. I would expect more curvature in a lensed galaxy. Another problem is the lens galaxy itself...
The other bulges are areas of intense star formation, this looks like quite a young galaxy (relatively speaking 😉 )
The green / blue cloud is an artifact 😃 They are not real - you can look Here for more info 😃
That is an artifact - it could be particle strike or a imaging error. Whatever it is it is not real 😃
I am positive it is a galaxy - or four!
They are both foreground stars 😃 It is only by line of sight they look like they are connected. The pixelation is a artifact.
Sort of 😃 Bright objects cause some interesting colours in the UKIDSS infrared images. In this case the magenta core happens to be a #QSO
Yes, that certainly has features of a spiral galaxy 😃
Yes 😃 A lovely one at that!
No, it is a galaxy 😃 It just looks a bit odd as this is an infrared image (see the label UKIDSS in the bottom right of the image?)
Yes, an #artifact !
You can if you want too, but it is not necessary 😃
No lensing - Sorry! That a spiral arm 😃 #no_lens
That is an artifact. Only visible in 1 filter, and not visible on the optical image.
The bright blue object is a foreground star from our own galaxy - The Milky Way 😄 More info Here
Looking at the interaction between the two I would say - #merger . In the optical image the smaller galaxy has a odd color. Sadly no spectra
No lensing - Sorry! It is a artifact caused by the brightness of the galactic core. It is quite common in the UKIDSS infrared images.
There certainly looks to be interaction between the two, and the blue colour in the arms indicates dense star formation. A likely #merger
Just classify the one in the center - thanks 😃
Some of the red dots are much more distant galaxies, others are foreground star. Difficult to tell in these infrared images.
Hi @Lozang and welcome - remember it is the object at the center we are classifying 😃 In this case it is a smooth elliptical galaxy.
Here is optical image: http://tinyurl.com/ldbj9qv Looks like we have a lovely inner #ring 😃
#Barred #spiral with the arms possibly settling into a ring. Noticeable bulge - will be interesting to see the optical image...
What a gorgeous #merger and looking at the red shift these galaxies are quite close - relatively speaking of course 😃
Ooops - In my previous comment in this thread I meant to say it is not an overlap - it is most likely star formation. Sorry @maglis 😃
I would of classified it as a artifact! Something went very wrong with the imaging / processing 😃
3/3... with these acronyms - they are basically the same thing! Think I will have to do more digging, once I have finished my dinner!
2/3.. I would say no. It is also flagged as QSO_Reject. Then looking on SIMBAD it has been flagged as an AGN. Don't get confused with..
1/3.. This is a confusing one! It has a really bright core which would suggest it is likely, but looking at the Spectra found on Skyserver..
#AGN #Seyfert_1
#AGN #Seyfert_2
#barred #spiral #seyfert_1
I would go with #merger we have clear interaction btwn the central galaxy and the smaller companion. The galaxy at 11 also looks connected.
This in a infrared image so they are a bit difficult to classify 😃 That arc is a spiral arm, but even in the SDSS image it is fuzzy.
The UKIDSS images are sometimes difficult to classify - I would go with spiral / obvious bulge
That doesn't look like a merger to me - sorry! Even looking at the optical image I am more inclined to go with star formation.
Wow - that object is almost microscopic! There is no way to tell if that is a very faint foreground star or distant galaxy!
#merger for me. Clear signs of interaction with starburst activity. Distended arm to the right.
A very tight spiral? possibly SBb?
As for the process of star formation, you can start here: http://en.wikipedia.org/wiki/Star_formation
They are both foreground stars from our own galaxy - The milky way.
A galaxy with a very bright core 😃
The blue objects are all foreground stars from our own galaxy. #No_merging.
Always classify the object at the center! In this case the smooth galaxy.
The colours are not real, something went wrong with the imaging - sorry!
They are foreground stars from our galaxy. In this case it is a star cluster. Try having a look on SkyServer - very impressive!
I would go with merger. 2 of the objects have a similar redshift and there are signs of interaction. Hope this helps!
A very disturbed galaxy in the process of merging with another galaxy. Here is the optical image: http://tinyurl.com/lcupvoj
2/2.. will have an intense blue colour. I have heard them being referred to as starbursts / starformation regions and nurseries 😃
1/2.. You can tell from the spectra, or in optical images, looking at the colour of the galaxy. Young stars are hot and blue, and areas...
The co-ords are the same but it appears that both NED and SIMBAD are also referencing a foreground star at a similar location. Line of sight
Looking at the optical image it looks like a very disturbed spiral galaxy, possible merger.
A foreground star overlapping a much more distant galaxy 😃
It is an artifact caused by imaging / processing.
It is an artifact.
The red object is also a galaxy, according to NED it is a 'red compact'. It also has a interesting spectra 😃
The streak is a diffraction spike,
and the green circle is a artifact 😃
The forum is pretty much dead. Only active threads are the game ones - sad, but true.
Hi All 😃 it is not necessary to comment / hash tag everything we find on SkyServer - we can already cross reference the data.
The blue object at the bottom is a foreground star from our own galaxy 😃
It's a dust lane 😃
What a lovely galaxy cluster! More apparent in the SkyServer image.
No lensing - just 2 interacting galaxies!
The answer is in all the comments below 😃
Hi @ntac - the bright blue object is a star from our own galaxy. Hope this helps!
An imaging / processing error - sorry 😦
The blue bits? It is an artifact, but what causes this particular type I do not know.
here is your galaxy in the optical: http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=194.48794084&dec=5.42073171
This is an infrared image so the colour scale is different. Red means bright.
Yes 😃 It is a satellite trail.
@lostlens - please stop deleting your previous comments. There is clear interaction between the 2 galaxies, with some nice tidal streams.
The galaxy looks somewhat disturbed, but that is not down to the bulge. Dust lanes is a likely cause.
It is an area of star formation or a star burst within a spiral galaxy. In this case it is part of a larger object, so classify the galaxy.
#merge
excellent!
It is your classification we are interested in 😃 but barred spiral looks good 😃
English please 😃 We can't support all languages and I guess you do not speak Afrikaans?
@lostlens why do you think it is a overlap and not a merger?
So their is no confusion this is a optical image (SDSS) not a infrared image (UKIDSS), Makes a big difference.
Yes 😃 and it has triggered off loads of star formation in the left galaxy. That is why it has a blue colour - young stars are blue.
Far from it! This is an infrared image, so it has a different colour scale. Have you had a look at the optical image on SkyServer?
The stars would of masked out the much more distant galaxies. Still an amazing star cluster!
I do not see any signs of lensing. Looking at the optical image I would say dust in an oblique spiral galaxy.
What a beauty! Amazing #spiral with loads of star formation
Yes 😃 both of the blue / green objects away from the galaxy are foreground stars.
This is a spiral galaxy so it is less dense in the arms at the edge of the galaxy.
And you would be correct 😄
That is a satellite trail 😃 Not blue shift, but rather different filters during its transit.
3/3.. the bulge. These are rare, and it would have to be a big spiral. This one is a bit of a lightweight 😃
2/3.. have a smaller mass than older ellipticals. Spirals can cause lensing, but they tend to be edge on, with the lens focused around...
1/3.. I am also going to add my vote of #no_lens . Firstly it is the mass of the galaxy that causes lensing. As Els mentioned spirals..
The redshift is quite similar, but apart from the proximity, there is not much interaction. Gravitationally bound rather than merging?
... also, the 3 objects have similar colouring in the optical image. If this was a lensed quasar the colour difference would be noticible
No lensing for me 😃 More like a cluster. The galaxy at the centre would not have enough mass to cause lensing of that magnitude...
Yup - stars do amazing things don't they 😄
No merging or collision - possible gravitational #lens. Very nice.
They are all foreground star from our own galaxy - The Milky Way.
It is a foreground star from our own galaxy.
Here is the same galaxy in the optical: http://tinyurl.com/nep857a
That is a galaxy! This is an infrared image, so if the galaxy has a bright core there can be some color distortion.
That is a foreground star from our own galaxy, they are so bright they over saturate the camera.
Okay 😃 It is just confusing to newbies, they then get the impression the whole image needs to be classified.
I would go with irregular galaxy. Looking at the optical image there is loads of star formation going on.
It is definitely showing sign of being a spiral galaxy 😃 The UKIDSS images are a bit more difficult as the features are fainter.
Remember to only classify the object at the center!
That red line is a satellite trail - more info Here
From this image alone I would say it is showing signs of interaction. Possible fly by?
I would also go with #barred #spiral 😃
Yes 😃 a #spiral galaxy - It looks more impressive in the SkyServer image.
They are both foreground stars - this is a infrared image so the colour scale is different.
2/2... they tend to over emphasize the brightness of the core. Also to make the classification you would need spectra. This galaxy has none.
1/2... @MikeOborn - just because a galaxy has a bright core, it does not mean it has an AGN 😃 These UKIDSS images can be misleading as ..
I would also go with bulgeless 😃
The object at the centre is a galaxy. I am inclined to think the other 2 objects are foreground stars.
The bright object is a foreground star from our own galaxy - The Milky Way. Have you read this
Another possibility is that it is a late stage merger. Pity we don't have spectra, as SkyServer has this flagged as 2 galaxies.
The bright object is a foreground star from our own galaxy. The object you needed to classify is the tiny orange object at the center.
It is a processing / imaging error, if you look at SkyServer you can see it is a nice galaxy cluster.
No 😃 It just looks that way due to line of sight.
That is an optical artifact 😃 More info look Here
It is an artifact caused by the brightness of the core of the galaxy. The infrared images are very sensitive, and oversaturation is common.
2/2.. objects not at the center will have a chance to be classified in other images.So all objects get a chance. Hope this helps 😃
1/2.. Only classify the object at the center of the image, the only exception is if it is interacting / merging with another galaxy 😃
It is a spiral galaxy with lots of star formation 😃 Although looking at the optical image there is a weird 'bulge' in one of the arms ?
I would also agree #merger 😄
No lensing - Sorry 😦 It is just an optical artifact around a foreground star.
Those are diffraction spikes - usually caused by the wires that hold up the secondary mirror in the telescope.
In the top left? That is a foreground star from our own galaxy.
I am also concerned that there are too many other similar coloured objects close to the galaxy, for it to be lensing.
No planets 😃 That is a foreground star from our own galaxy.
Yes 😃 but remember to only classify the object at the center.
Always classify the single galaxy right at the center - the other objects you can ignore.
Galaxy on the left, foreground star on the right.
Um, why? Just a galaxy and a amazing foreground star 😃
2/2... If you follow the hyperlink posted by @lostlens below you will see the optical image.
1/2...It is an infrared image so only the brightest objects are visible, that is why the galaxy you have to classify is so faint.
Sorry - no ring galaxy! It is a foreground star from our own galaxy 😃
This is a UKIDSS image, so only the brightest arms are visible - looks quite different in the optical!
It is a very disturbed spiral galaxy - could be a result of a fly by or merger.
The dots are not real - it is artifacts that were generated during imaging or processing.More info here
I am not seeing any signs of merging, and the bright blue object in the bottom left is a foreground star 😃
That is a foreground star from our own galaxy - the strange colour are caused by over saturation. Info
No lensing 😃 and the green line is a satellite trail - look Here for more details.
The green / pink object is a foreground star from our own galaxy 😃
The green dots are a common #srtifact from the UKIDSS images.
No lensing 😃 The 2 green circles are artifacts. More info Here
pleasure 😃
Hi @benhoofe1 😃 Which object are you referring to?
I would also go with #merger
Not unusual to have a large bulge at the center of the galaxy 😃 Although this galaxy does seem a bit disturbed. Possible interaction?
It is a #merger between multiple galaxies, loads of interaction, and stunning dustlanes 😃
This is a difficult one to classify as it is the pale blob not the orange blob that you need to classify - For me star/artifact 😃
The green dot could be an artifact as it is only visible in the 'r band. The white / purple blob could be a foreground star.
Other ideas?
Very similar redshift, and we can see interaction - so I would say #merger 😃
I would go with a two armed spiral - it is more prominent if you look at the SkyServer image.
Yes, the green dots are an artifact 😃
It is a artifact that was generated during imaging or processing. More info here
#no_lensing for me - more likely to be star formation 😃
That trail is a diffraction spike from a star - you can see it clearer in the Skyserver image.
Correct 😃 artifact
@Wisi_EU but someone classifying the image would not have access to that data 😉
Wow, indeed 😃
#NGC5033
here is the full image
That is an sattelite trail, for more info look Here
Sorry 😦 no X-shaped bulges - we would only see them in edge-on galaxies, this is clearly an S0 elliptical.
Not entirely convinced it is an AGN, possible merger with star formation perhaps?
The green dots are artifacts 😃
It is a fuzzy #barred #spiral
@Jonas.dreesen do you have a question? 😃
Here is the optical image and the spectra. It look like a normal red elliptical galaxy - no AGN 😃
Hmmm - I am not seeing anything that suggests this is an AGN. I am interested to know why you think it is one? 😃
Hello and welcome @VjMilo - do you have a question? 😃
Certainly looks like it in the optical image here
No, I do not see anything that would suggest this was a merger, but it is a lovely #barred #multi_armed #spiral 😃
Not a nebula - a galaxy 😃 Here is the optical image of the same galaxy (slightly rotated/flipped).
That is because the images on SkyServer are optical images, this is a infrared image from the UKIDSS survey 😃
All stars from our own galaxy - the lovely colors are artifacts caused by saturation.
No supernovas 😃 Foreground star from our own galaxy, for more info look Here
Sadly not 😃 It is not unusual for a galaxy to have a bright core, without having an AGN. Also, spectra says no.
Similarly, the spectra does not suggest an AGN.
Looking at the spectra I would day no AGN.
#satellite trail, they tend to look like rainbows in the UKIDSS images.
No lensing - that is an artifact - for more info look Here
Looking at the optical image, looks like a young #star_forming galaxy - somewhat #irregular
#boxy #edge_on galaxy
The galaxy at the center is really quite interesting... #barred #ring #agn_possible
Not a planet 😃 Just a diffraction arc caused by a bright star off screen.
It is not unusual to have more than 1 galaxy in a image, but only classify the one at the center.
I would say yes 😃 The other three multi-coloured objects are foreground stars.
The green ring is an artifact - for more info look Here
#barrred #spiral - with the UKIDSS images the features of the galaxies are a bit harder to see. Always classify what you think you see 😃
... looking at the notes in NED has been previously analysed by astronomers as a high HII region.
This is an infrared image from UKIDSS so it will look a bit different from the optical - loads of #star_formation, quite unusual...
No gravitational lensing 😃 I would say merger, or gravitationally bound galaxies.
See answer in the comments below 😃
It is a foreground star from our own galaxy - so you were right! 😃
Very faint galaxy with #spiral features. To the right a star. Always remember to only classify the object at the center 😃
The green object is a artifact that was generated during imaging or processing.Read this for more info.
It is a galaxy - this is one of the UKIDSS infrared images so the colour can be a bit weird. The pink is caused by a really bright core.
That cloud is in fact another galaxy #UGC06970 - looks more impressive in the optical.
Both are stars from our own galaxy - the lovely colors are artifacts caused by saturation, more info Here
The central object is a galaxy and the object on the right a foreground star. No nebula - sorry!
It is a galaxy - just viewed in the infrared. Here is the optical image of the same galaxy.
No, I don't think so as. I am not seeing another object it could be interacting with.
Most certainly a loose spiral, a bit more difficult to tell if it is barred. I would go with unlikely.
@jonas.dreesen - Hi and welcome 😃 What object are you referring to?
It is a artifact that was generated during imaging or processing.Read this for more info.
All stars from our own galaxy - the lovely colors are artifact caused by saturation.
The green dots are artifacts - you can read more about them Here
That is a foreground star - this is a infrared image so they tend to look a bit strange 😃
Always classify what you see 😃
Being able to look at the SkyServer image is a bonus, but not necessary 😃 I would say #merger
Wow, amazing #tidal_trails
We certainly have a #bar , this being a UKIDSS image I will go with #spiral not ring.
I would go with edge on 😃
That is interesting! Clearly visible in 'i and 'z filters, not entirely convinced, but should be looked at. #lens
This one is definitely a galaxy 😃
First off ignore the star, we are only classifying the object at the center - a #barred #multi-armed #spiral
I think it is safe to tag them as #merging 😃
They are all next to each other - here is the optical image: http://tinyurl.com/o3l58q5 (you may need to click 'get Image' on the left)
No! An amazing #edge-on galaxy!
Nice! It is a galaxy, but the reason for the strange colour is that it is harbouring a #QSO - a quasar for us laymen 😃
That a star - but yes, they do create amazing artifacts 😃
I don't think it is an artifact - perhaps another galaxy?
No lensing for me 😃 This is a infrared image, and they do tend to create some spectacular artifacts
#merger and #agn - nice!
I really wish they wouldn't do that - makes things hard for us astronomers 😉
That does look quite exciting - the resolution is not so good, but I will also add my #lens tag
Sadly not 😦 It would be awesome if it was! The brightest object on the left is a star. The other objects look like satellite galaxies.
The blue and green dots are indeed artifacts 😃
no lensing #barred galaxy
No lensing - This is a infrared image, so the purple discoloration is a artifact #starformation #spiral
They are both artifacts.
No merge - just intense star formation. This is a infrared image, so only IV sources will show up.
This is an infrared image... do you mean optical?
The blue object at the top of the screen is a foreground star from our own galaxy.
I would go with a loose 2-armed spiral 😃
#star This is a foreground star from our own galaxy
These are foreground star from our own galaxy.
The green dots are artifacts, not too sure what went wrong.
The blue / green object is not real - it is a artifact that was generated during imaging or processing. Hope this helps 😃
Well it is a star from our own galaxy, so it would appear larger than a galaxy millions of light years away 😃
They are all local stars from our own galaxy
An artifact...
Sadly not. The ring is an artifact, and the galaxy is a lovely #edge_on
That is a foreground star from our own galaxy - the Milky Way 😃 The discolouration is due to over saturation.
That is a foreground star from our own galaxy. The strange color is due to over saturation 😃
...satellite galaxy perhaps? No redshift on either of the galaxies.
On the left we have a star, so your are correct! I am still undecided about the galaxy on the right, there could be some interaction...
In the UKIDSS infrared images it indicates a very bright area, this could mean an AGN, but we would need to look at the spectra.
Not seeing much interaction, so personally i would go with #overlap. They could be gravitationally bound, but without redshift, can't tell.
The blue / green object is not real - it is a artifact that was generated during imaging or processing.
No, it is a galaxy - According to NED - a ZOAG (Zone of Avoidance) Galaxy. That just means it is 'behind' the milky way.
Here is the optical image - really nice! http://tinyurl.com/AGZ000703x
(you might need to click on 'Get Image, on the left)
Looking at the redshift and NED - yes, it is a cluster 😃
I would personally say yes. Nice!
It is a disturbed #spiral galaxy. Looking at the spectra, we have a lot of star formation going on 😃
Sadly not! The brighter object is a foreground star overlapping a galaxy. Hope this helps 😃
The central galaxy or the star to the right?
It is a satellite trail - look here for more info: http://tinyurl.com/GZartifacts
That is a foreground star from our own galaxy - The Milky Way.
Those are all foreground #stars - the 'jet' is a diffraction spike (another kind of artifact)
That is an artifact 😃 Have a look here for more info http://tinyurl.com/GZartifacts
That's most definitely an artifact 😄
I would go with merger
A very disturbed galaxy with star formation, possible later stage merger. I think the red dots are foreground stars.
Looking at the spectra, I think we can discount AGN.
No, irregulars are a lot more disturbed and when viewed in the optical SDSS images they are blue. This is one of the more difficult ones...
I would go with #merger
It could be a #merger or #overlap - difficult to tell without the redshifts of both galaxies.
What a gorgeous #spiral
The different coloured objects are all foreground stars from our own galaxy 😃
That would be my choice as well 😃
It is a #spiral , but in my opinion it is not disturbed.
They both have the same redshift, so I would say yes 😃
It looks like it :- )
Only in the SDSS images... It will be different for each survey 😃
That is an artifact - the brightness of the hub of the galaxy causes over saturation in the camera.
No voorwerpjes - as this is a SDSS images they would be a vivid bright blue 😃 I do agree with #star_formation
I do not think they are colliding 😃 But interesting... chance alignment? or something else?
It looks like a star cluster. SkyServer has it incorrectly flagged as a galaxy.
That is a new one.
We really need a gallery for them!
The red object? No, it is a foreground star from our own galaxy 😃 We also have a gorgeous elliptical galaxy at the center.
A foreground star from our own galaxy. Awesome 😃
The two objects bottom left are foreground stars. At the center we have a lovely fuzzy #barred #spiral 😃
These infrared images can be a bit deceiving - that is in fact a spiral arm. Have you tried looking at the SkyServer image? Lot clearer!
An artifact- sometimes the brightness of the hub of the galaxy causes some interesting optical artifacts in these infrared images 😃
That is an artifact 😃 It is not real - look here for more info: http://tinyurl.com/GZartifacts
I would go with your first choice - optical artifacts 😃
Looking at the optical image, I would say yes. Nice!
We have a foreground star from our own galaxy in the top right. Happy Hunting!
No merger for me - we have a foreground star to the right 😃
This is a #spiral galaxy
It's a foreground star 😃
We do have areas of star-formation in an irregular galaxy, but I think the 2 big blue objects at the bottom are foreground stars.
These are infrared images, so objects will look different from there optical counterparts.
The red object is an artifact, it is not visible in the optical image.
The blue objects are indeed stars from our own galaxy 😃
That red circle is an optical artifact - have a read here for more info: http://tinyurl.com/GZartifacts
...terminology - It can be confusing for new users 😃
@MikeOborn - on GZ we use the word 'Smooth' to classify an elliptical galaxy. This galaxy is clearly a spiral - please be careful of your...
No 😃 Not a black hole - looks like we had some major imaging issues. Everything is accounted for on the optical image 😃
The 3 bright objects are in fact foreground stars from our own galaxy 😃
It is indeed an artifact - it is not visible in the optical image, so it is unique to the infrared survey.
That green blob is an artifact 😃 Rad this thread for more info http://tinyurl.com/GZartifacts
Yes, it is still a galaxy! Possibly a dwarf galaxy? but it does look somewhat more robust in the optical image.
A galaxy - this is a infrared image, so not everything you would usually see in a optical image is visible.
I don't think so as it is not visible in the optical. Thinking artifact.
Another type of artifact - a diffraction arc.
No, that tiny image at the center is the one you have to classify. In this case somewhat difficult... 😄
Hmm - I am not seeing an AGN in this image. This is in the infrared so we would expect to see some color distortion. Nothing on NED/SIMBAD
I would of classified it as having one, along with a #bar
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=126.98636731&dec=28.27504432
This is an infrared image - so it is not the same as viewing it in the optical 😃 In the optical your galaxy has a pair of fuzzy arms...
That is just an artifact caused by oversaturation.
AGN's are not limited to spiral galaxies, a famous example is M87, an elliptical galaxy.
That blue coloured object is a star from our own galaxy 😃
It is two galaxies merging - Stunning!
the yellow objects at the center are both galaxies.
Sadly not - just a star from our own galaxy 😃
Another artifact 😃
Sorry! The black dot is a artifact. It is not visible in the SDSS DR8 image.
The blimp near the galaxy is also not identified on NED, I cant help thinking it is an overlap... intresting.
I would go with #irregular galaxy 😃
The blue object is a star from our galaxy. The rust object is a more distant galaxy 😃
I do not think it is a merger, star burst perhaps?
Look like a awesome #merger 😃
No merger for me 😃
Yes they are 😃
I think #overlap as I do not see much interaction. Color of the smaller galaxy suggest is a lot more distant than the central.
No lensing, but areas of dense star formation. I once read that it is not unusual to have these starbursts at the end of bars...
... will need to find the source for that!
The blue object is a foreground star from our own galaxy 😃 The other objects are unrelated to the star or the galaxy.
A #merger possibly a #triple - looking at the optical image we have loads of star formation going on!
Most definitely a star!
Hi @MikeOborn - a smooth galaxy would have no features or spiral arms. This is a spiral galaxy, with clumps of star formation in the arms.
They are artifacts - look here for more info: http://tinyurl.com/GZartifacts
Yes, it is not unusual to have clumps of star formation within a galaxy.
Yes, the red dot is an artifact.
Could also be a satellite galaxy, or a dense area of star formation.
Another form of a artifact - in this case a diffraction arc caused by a bright star off screen.
SkyServer is not always correct - I would also go with star!
snap 😃
This one is a galaxy, the color distortion at the center is an artifact due to a very bright galactic hub.
Yes it is 😃
I wish 😃 The object at the center is a galaxy. The line intersecting it, is a diffraction spike from a really bright star just off screen.
They are stars from our own galaxy - the Milky Way
Hi and welcome 😃 That bright object is a foreground star from our own galaxy. Really nice #barred #spiral galaxy
I would say it is highly likely - lots of interaction. Here is the optical image: http://tinyurl.com/AGZ00069j7
We have no spectra on the image, but looking at the brightness it is possible. Dense star formation is also possible.
That less bright object is another galaxy - looking at its colour in the SkyServer image, it is quite a lot further than the center galaxy.
It is an artifact caused by the brightness of the core or hub of the galaxy.
Definitely a foreground star - SkyServer is not always correct.
Skyserver has it flagged as one 😃
According to SkyServer they are both galaxies, with similar redshift. #merger
Looks like merging galaxies, so the bright spots you are seeing are dense area of star formation triggered by interaction.
They are optical artifacts 😃 Look here for more info: http://tinyurl.com/GZartifacts
I would say they are merging galaxies 😃 Sadly no redshift, but it is clear that we have interaction between the two
The 2 blue objects are foregrounds stars from our own galaxy. The object in the middle is a elliptical galaxy.
Hi and welcome 😃 That is a star from our own galaxy.
No lensing 😃 it looks like a cluster of galaxies.
It is a galaxy - it looks a bit odd as this is one of the infrared images.
More info on both here: http://tinyurl.com/GZartifacts
At the top of the screen we have a diffraction spike from a bright star off screen. The weird one at the bottom is an artifact.
That red line is a satellite trail 😃 Read this for more info: http://tinyurl.com/GZartifacts
I do not think it is a merger. Looking at the spectra, there is a lot of star formation going on in this galaxy
#disturbed #spiral with star formation. Possible flyby - on SkyServer we have another disturbed galaxy at 3.
The blue object is indeed a star, and I agree with the comments below - there does seem to be interaction going on.
No lensing for me - looking at the optical image the points are different colors - that would not happen with lensed quasars 😃
The multi-coloured object at the top is an artifact 😃
Yes 😃 The bright blue bits are areas of star formation. Nice 😄
I agree - it is a merger. Nice 😃)
no gravitational lensing - a nice #barred #spiral with stars and other artifacts...
Sorry, No. Something went really wrong with the imaging 😦
It is an artifact - still under much debate as to the cause. Happy hunting 😄
A star 😉 It is a diffraction spike. The star is just off screen to the right...
There is a whole thread on Boxy Bulges on the forum: http://www.galaxyzooforum.org/index.php?topic=275643.0
#dustlane ... not so sure about boxy. Boxy bulges tend to have an 'X' embedded in them.
nice #dustlane 😃
Hmmm - definite bar, but personally no ring for me
...or it is just a random alignment.
He sure does get around a lot 😉
@lostlens : having analysed the NED / SkyServer data myself, can you please explain what you mean by 'no kinetics'.
Sadly not! It would be awesome if that were true 😃 In this case the green and blue dots are artifacts.
An overlap between a galaxy and a star.
The blue object in the lower left of the galaxy is a star, it is clearer in the optical image - Happy Hunting 😃
If the redshift was greater, it could be one of PeterD's blue catapillars
At the center? I would go with galaxy.
I am not seeing much interaction between the 3, so #overlap is also a possibility.
Sorry - that is an artifact! No galaxy.
You are right! It is a stunning dustlane 😃
Both blue objects are foreground stars 😃
Yes 😃 and it is stunning! Also - nice #bar
No lensing - the light blue objects are foreground stars. The dark blue spots are artifacts.
That a star from our own galaxy 😃
Interesting question - but totally unconnected with this galaxy 😄
The blue blob is a foreground star from our own galaxy 😄
That is a artifact - have a read of this for more details: http://tinyurl.com/GZartifacts 😄
No lensing 😃 A gorgeous #barred #ring galaxy
They are artifacts - more info here: http://tinyurl.com/GZartifacts
Always classify what you see - it is your opinion that is important! In this case you could of chosen odd -> other 😃
That object is a foreground star from our own galaxy.
The red object is an artifact - more details here: http://tinyurl.com/GZartifacts 😃
It is a foreground star from our own galaxy - have a read of this http://tinyurl.com/GZartifacts
According to SkyServer it is 3 galaxies - but without redshift for all 3 it is difficult to tell if it is a merger. I think #overlap myself
@Rudy87 - what object are you referring to? 😃
That smaller object is a star from our own galaxy. It only looks blue/white as this is an infrared image. If you look on SkyServer it is red
It is a foreground star from our own galaxy - it looks a bit strange as this is an Infrared image
The blue dots and circles are artifacts - look here for more info: http://tinyurl.com/GZartifacts
I would say the pink and yellow object looks like a star. The brightness of star can cause some interesting artifacts 😃
I would say the smaller one is a neighbouring galaxy - possible interaction between the two 😃
They are both galaxies - looking at the interaction between them, I would say possible merger.
Sadly not - the bright blue objects are foreground stars. They look a bit different as this is an Infrared image 😃
I would say yes 😃 nice #bar as well
Looks like the image is a bit #misaligned. When looking at the RA/DEC it is the #edge_on galaxy on the right
Looking at the image as is - I would go with spiral 😃
#greenlatern must be running out of steam - he appears to be fading 😄
Think of it as two galaxies dancing round each other and eventually combining into one galaxy 😃
It is a trail of stars 😃 The two galaxies are merging, so the stars from both are being 'thrown' together and are forming tidal trails
Looking at the Spectra I am not so sure it is an AGN - almost certainly a merger, and that can trigger intense star formation. Scientist?
That is an artifact 😃
I would also go with 2 stars, but I think they are just overlapping and not colliding 😉
You are right - that is a star!
Relatively speaking, and compared to the other galaxies we are classifying, that would be a very close 😃
The golf ball is a foreground star from our own galaxy 😃
The top galaxy look like an #edge_on galaxy. Remember to classify the object at the center! 😃
The green object is an artifact - have a read of this: http://tinyurl.com/GZartifacts
The lower blue object is a foreground star from our own galaxy 😃
That is most definitely a galaxy! I would say an E0 Elliptical 😃
SINBAD also has it listed as having an #AGN
It is a galaxy that has a lot of active star formation going on - that is what is giving it a weird color in this infrared image 😃
I would go with #disturbed #spiral - there may also be hint of a #bar.
The blue object is a foreground star from our own galaxy. It looks a bit strange as this is a Infrared image.
Artifacts -) Have a look here for more info http://tinyurl.com/GZartifacts
It is an artifact - have a look here for more info 😃 http://tinyurl.com/GZartifacts
The big galaxy is #NGC4448, the one that needed to be classified was the tiny one at the center of the image, being somewhat obscured 😃
They are artifacts - there is still some discussion on what causes them.
It is a spiral galaxy #NGC0245 - The blue areas in the arms are starbursts - regions of intense stellar formation,
Those all look like foreground stars (and SkyServer agrees 😉 ) - possibly part of a cluster.
In this example, I would go with smooth 😃
It is an optical artifact - look here for more info http://tinyurl.com/GZartifacts 😃
Looking at the optical image, there are similar objects elsewhere. More distant orange elliptical galaxies perhaps?
The reddish object is an artifact. Looking at the redshift the galaxies are gravitationally bound / merging.
Not quite - it would then no longer be a spiral, and would be classified as lenticular.
Might be the result of a flyby.
It is also a galaxy - very disturbed due to collision / interaction. Have a read of the discussions on the right...
I would agree with that - chance alignment between galaxy and stars 😃
They are artifacts 😃
I would go with #ring - definitely not a lens.
You are correct - it is a star 😃
Wow - what a stunning #barred #ring #spiral galaxy
I would go with spiral. We also seem to have an #overlap
The blue and green dots are artifacts. The galaxy in the middle looks like an E7 elliptical galaxy.
No supernova - just a star 😃
No 😃 The blue object at the top is a star - infrared images such as this one are sometimes difficult to classify 😃
I am not sure - looking at the optical image I would of said the object on the right is a star. SkyServer has it listed as a galaxy.
Sadly - the bottom right object is a star from our own galaxy.
At the center? Not a star - a very faint galaxy.
I would agree. #toofainttoclassify
Looking at it, I would say yes 😃
No it is not an arc 😦 Something went very wrong with this image.
Sorry - no merger, the orange blob is a star from our own galaxy.
Not really 😃 A stunning barred spiral, still a bit undefined but give it a few millenia..
@Wisi_Eu but classifying the image you would not know that 😉
Welcome 😃 and happy hunting!
The UKIDSS images are sometimes difficult to classify, but I would of done the same.
Hi nicro46 - It has a quasar at its core, and that is what is causing the weird colour - you should take a look at the spectra 😃
A disturbed galaxy with spiral features - this is an infrared image, so it looks a bit weird.
It is a galaxy with a very bright core 😃
SkyServer has it flagged as a star. Looking at the optical image I am inclined to agree.
No lensing 😃 A chance alignment - the blue objects are both stars from our own galaxy
Looks like a typical spiral arm to me. We can rule out tidal arm as I do not see an interacting galaxy. The spectra rules out QSO.
The bluish green object is a star, the 'tail' is an artifact.
I think that is an artifact as it is not visible in the optical image.
Mmmmm, I think it might have a spiral pattern 😃 Just a bit undefined...
No lensing - the blue objects are both star from our galaxy 😃
Es un sendero de satélite - que se mueven con rapidez, por lo que sólo se capturan en un solo color.
The bright object in the top left corner?
Looks like we had a problem with the chip.... Processing error.
It is another galaxy, but without the redshift of both it is difficult to say if they are related. Thinking #overlap is more likely.
I do not think it is an elliptical, thinking more likely lenticular or edge on. Have you tried looking at it on SkyServer?
lol 😃
According to Skyserver both the objects are galaxies, I think #overlap as I do not see much interaction. Also, this is an infrared image 😃
In this case I will say misaligned filter - the same artifact is visible on other objects in the image.
It is a #star - stunning! Welcome 😃
That is an artifact - I have only seen this type cropping up in the past few days. If you look at the optical image it disappears 😃
On the top right they are other galaxies 😃 Bottom right a star.
#QSO
Wow - that is an awesome one!
I don't think it is a merger, no interaction. I would go with #overlap
I would say the same...
No exploding stars 😃 A chance alignment between a distant galaxy and a star from our own galaxy.
Not a nebula, but a galaxy 😃
2/2 ...visible in other object when viewed in SkyServer. Artifact perhaps? Anyone else?
1/2 I don't think it is a lens (or arc) , as we would expect it to have a different color to the lens galaxy. The discolouration is also...
I would of classified it as having spiral features - but your opinion is more important 😃 There is no such thing as a wrong answer...
It could also be an #overlap or #sattelite_galaxy - difficult to tell without the redshift of both galaxies.
Foreground #star for me!
Star forming? Yes, it is - we can tell by looking at the colours and the structure of the galaxy 😃
It looks like a late stage merger. This is a UKIDSS image, so it was taken in the infrared, that would account for the strange color
Sadly not:-) It is a star from our own galaxy
No lensing 😃 just star formation in a spiral galaxy.
It is an artifact - look here for more info: http://tinyurl.com/GZartifacts
Difficult to tell as we don't have the redshift of either object - #overlap is also a possibility.
I would go with #spiral features and #bar 😃
Hi and welcome ghareth 😃 that is an artifact at the center of the galaxy. See here for more info: http://tinyurl.com/GZartifacts
I do not think it is a merger - looks like it is a single galaxy!
It does look quite busy, but I am not sure if we could call it a cluster?
I think it is just a chance alignment - no merging for me.
That is an artifact - first time I have seen one like that!
Wow, that is a nice one!
Looks like something went wrong with one of the filters or the image processing.
Both are stars from our own galaxy 😃
Not too sure, the optical image is also very noisy. Looks like a merger, so it is quite disturbed.
Not a dust lane - we have 2 distinct cores - I personally would go with merger.
I would also go with #overlap
I would say it is a post merger. I do not think the galaxy on the bottom left is connected to it.
You could try looking at it using Galaxy Zoo examine?
The galaxy has a #dustlane, that would account for the redness you are seeing.
here you go! http://talk.galaxyzoo.org/#/boards/BGZ0000005/discussions/DGZ0000lv2
Looking at the respective redshifts (z=0.049 vs 0.066) I would personally go with #overlap.
lol - Els beat me to it!
I would agree with both of you 😃
It is an artifact - there are several in this image.
And you would be correct 😃 Have you tried looking at your galaxy using 'examine'? It really is spectacular!
It is an artifact 😃 In this case, the core of the galaxy was too bright for the camera and the image became over saturated.
We are not too sure what causes this type of artifact, but it could be due to a reflection within the camera itself.
Hi Gapella, I do not think it is a voorwerpie, the color distortion could be due to a bright star off screen.
It is a satellite trail - see ElisabethB's answer below 😃
And you would be correct!
That looks like a classic E0 elliptical galaxy, totally undisturbed - nice!
It is an #Artifact
Sorry! - I am not too sure what is happening.
No, it is not exploding, but it is a star from our own galaxy!
I would go with 3 stars 😃
Hmmm, I don't think this galaxy has a dust lane, looks like the discoloration is an artifact (for me anyway!)
The stars?
I would personally go with merger
They are artifacts, not too sure what causes them
See right for answer ->
The red center is an artifact caused by the brightness of the galactic core, NED does have the galaxy flagged as having a radio source.
and you would be correct!
I would go with spiral
That is star from our galaxy 😃
It is an #edgeon galaxy at the center
Foreground stars do not have the mass to cause lensing that would be apparent in these images 😃 Spiral galaxy perhaps?
No lens or arc for me - it looks like the galaxy has some spiral features
Hi Tsourakla, remember to classify the object at the center of the image - but yes, the other bright objects are stars 😃
Or a galaxy with 2 stars 😉 Difficult to tell looking at the image, but SkyServer has the northmost object listed as a star.
Remember this is a infrared image, so the galaxy will look quite different in the optical!
Another #diffraction_spike from a bright star off screen
I don't think it is interacting with anything, the odd discolouration is an artifact caused by the edge of the strip.
@eben.bosman - I have just been reliably informed there is no such thread - so I will make one 😃 May take a day or two...
It is a galaxy 😃
A #diffraction spike from a very bright star off screen.
Looks like a #tidal_trail they are usually caused by merging / interacting galaxies.
No UFOS's - just an artifact 😃
No, it is not a lens. It is too diffused and the lens galaxy does not have enough mass to cause an arc of that size.
..how to use it - but that will have to wait till tonight. Sorry, but I need to go to work.
click on 'View in Galaxy Zoo examine' just under the image above, and that will take you to tools. I will try and find a thread to explain..
Yes, that is a star under the galaxy. The galaxy looks very disturbed, even in the optical. Have you used the GZ examine tools?
In this case I would go with irregular.
Sure looks like it! Nice!
Some of the images are cleaned up to remove satellite trails, sometimes not all the pixels are removed.
It is a star - they do look a bit different in infrared.
#merger 😃 It is more apparent in the optical - but there is nice interaction.
I am happy with ElsB assessment that it is likely that there is an AGN at the center 😃
I am getting somewhat conflicting results in the various catalogues - there is a QSO somewhere in the image, but can't quite pinpoint it...
That is what NED says - I could have a second, more in-depth look, and that might take a bit longer - but it still looks like one to me 😃
Aha - NED has it listed as a QSO - that would explain the brightness 😃
It is an artifact - caused by a really bright core.
You are right - it is a sun of sorts - it is a star from our own galaxy 😃
No lensing @MartinTheK
They are foreground stars - And please remember your language, we are a family friendly site 😃
Yes, thats correct 😃
I think there might be more going on here. #Polar_ring perhaps?
Thats correct 😃 Remember these are infrared images, so the colour will be different in the optical.
II think it could just be an artifact, there is a similar coloured dot in the 11 of the galaxy, halfway to the edge.
No defect - the googly eyes are in fact stars from own own galaxy! Here is some more info: http://tinyurl.com/pbo34r2
I think it is a slight artifact, you can see similar discoloration elsewhere in the image.
No spectra so it is difficult to tell from just looking, but that quite a bright core. Also not flagged as having a QSO.
The redshift is quite similar (0.71 and 0.72) so they are quite close, can't see a lot of interaction. Nice #dustlane!
an #elliptical_galaxy
That is a star from our own galaxy - it looks so strange because its brightness overwhelmed the camera. http://tinyurl.com/pbo34r2
I think I do see a hint of a bulge 😉
No, but it is showing a few galaxies and a lot of stars - must be a cluster. Have you tried using Galaxy Zoo examine?
It is a artifact - if the core of the galaxy is very bright it can cause some complications with the imaging.
No lensing or a ring - Sorry! The bright core of the galaxy has overwhelmed the camera leading to an artifact at the center.
On SkyServer, the bright object in the 8 of the galaxy is a star, but the galaxy is very disturbed. Possible mid to late stage #Merger
Looking at it 'as is' - it seems like a disturbed spiral.
A galaxy at the centre 😃
I am not seeing any darkness - are you referring to the galaxy itself, or to the upper left from the galaxy?
No, it is a galaxy - it looks a bit strange as there is some discolouration (due to brightness) at the centre 😃
It is a star - non exploding 😉 Have a look here for more info : http://tinyurl.com/pbo34r2
I would go with that!
That is a star from our own galaxy 😃 Looks a bit weird due to over saturation.
It is an optical artifact as it is not present in the SkyServer image...
I will go with #merger - definitely not lensing, and there is a lot of interaction between the two.
Myself - loose 2 armed spiral - sometimes it is difficult to interpret an image, but don't be afraid of classifying what you see 😃
a #barred #spiral , look like we may have an #inner_ring
The bar is oblique across the bulge - not very big, but the arms extend from it on either end.
Wow, that is a good example! #xbulge
A #barred #ring galaxy - very nice! Looks like we may have an outer or polar ring as well 😃
No merger - the galaxy is in the middle of a star cluster, so it is a chance alignment 😃
The blue line is a satellite trail that was only captured in the blue filter.
They are optical artifacts caused by the bright stars - this thread has more info http://tinyurl.com/pbo34r2
Those are #arftifacts - have you read this thread: http://tinyurl.com/pbo34r2 really helpful!
Sadly not - an optical artifact 😦
You are correct - it is a #star 😃
Both of those blue objects are stars from our own galaxy - have you read this: http://tinyurl.com/pbo34r2
Hi 😃 That is a star from our own galaxy - have you read this http://tinyurl.com/pbo34r2
Yes, it is a star - the color is not true.
It is a star - the colors are optical artifact. More info here http://tinyurl.com/pbo34r2
It looks like something went wrong with one of the filters - Sorry!
And you would be right 😃 That is a bulge. Can you see the bar as well?
It is an artifact - have you read this: http://tinyurl.com/pbo34r2
No lensing - sorry! The blue object to the left of the center galaxy is a foreground star. Chance alignment.
2/2: ...in this case it is the hub or core of the galaxy.
1/2: The 2 darker circles are artifacts - no back holes in sight! The 3rd red one is an optical artifact caused by a really bright object...
Hi Lana4Light 😃 do you have a question about this galaxy?
I would go with #overlap = also stunning #bar and #ring
Not so sure about ring, but we do have spiral features - sometimes difficult to tell between the 2 when the galaxy is this fuzzy.
Hmmm, it think it is just a chance alignment. The galaxy looks too lightweight to cause strong gravitational lensing.
You are correct - they are artifacts - have you read this: http://tinyurl.com/pbo34r2
It is data from SkyServer / NED - it is the redshift of the two galaxies. They are at different distances, so it is an overlap not a merger.
I would go with a #merger of 2 ellipticals, they are quite #disturbed due to interaction.
It is difficult to tell in this case, but it looks like the tiny orange elliptical at the center.
I would also flag it as having a #bar and a #ring - I find going with your gut instinct is the best advice.
The one directly at the center, in this case it is the smaller smooth elliptical. The 2 objects on the right hand side are stars.
Dense areas of star formation - young stars are hot and blue, that is what is causing the discolouration in the arms.
Hi @BernardS88, do you have a question?
No black holes 😉 - I would say #merger as there does appear to be interaction.
You are correct - they are artifacts.
In this case I would say coincidence. You are correct, when taking into account the vast distances, any companions would be quite close by.
I would say neither. I would be inclined to classify it as star or artifact to flag it up, but ElisabethB would be able to confirm that.
Yes, that would be a classic sign of a merger. We would call it a tidal trail. In this case, quite possibly a #merger.
I would say yes #merger - Nice interaction between the two.
That is more definitely a galaxy 😃
BTW remember to classify the object at the center, in this case it is the rather dull, somewhat disturbed galaxy.
That bright object on the left is a star from our own galaxy - so no lensing 😃 Have you read this: http://tinyurl.com/pbo34r2
It might even have a bar... 😃
It is an artifact - for more info read this: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
Remember to classify the object at the center of the image - the bright blue object at the top is a star from our own galaxy.
That is a star from our own galaxy - the Milky Way 😃 More info: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
It is an artifact caused by oversaturation. Happens with really bright objects, in thus case the galactic core.
I am not seeing any interaction between the two, so chance alignment for me.
No merger 😃 The blue star is in our galaxy, the orange elliptical is many light years away.
Could also be a flyby? The centre galaxy does look somewhat disturbed. Pity we have no spectra.
Difficult to tell as the galaxy is very undefined in both the infrared and optical. My experience says no - sorry.
Hi @isadora do you have a question?
I dont think it is a artifact, it is also visible in the optical. QSO perhaps? Not a lot on SkyServey or NED. Also, no spectra.
It is not an artifact -I would say galaxy. Pondering between #dwarf or #irregular.
I am going to go with a star cluster within our galaxy. Could be wrong - anyone else?
3/3.. of the stars into account. So, the geo satellites would still move very slowing across the frame, but not leave much of a trail.
2/3... would not move as the satellite would be in a fixed position in relation to the earth. Edd pointed out I had not taken the movement..
1/3 ... I asked Edd (one of the GZ Scientist) how a geosynchronous satellite would look in these images. My thinking was that they...
Wow, that is stunning!
I would say satellite trails
Just one that is quite disturbed 😃 Spiral arms all over the place!
Hi @turelli - I am unfamiliar with this GPair hashtag, can you explain it for me?
Remember to classify the galaxy at the center 😃 and yes, the galaxy on the right has 2 spiral arms.
No ring - just an amazing #spiral viewed at the oblique. Nice dust lanes.
I would go with #dwarf or #irregular
Misaligned images between filters - Sorry!
Looking at SkyServer the orange thingy is another galaxy, but this image is very misaligned. I think you analysed the image quite well 😃
It is a foreground from our own galaxy - the Milky Way.
It is an artifact caused by the camera.
As ElsB said it is a optical artifact - happy hunting!
It is not unheard of 😃 Nice Example - also hints of a #bar
possible #sattelite_galaxy at the end of one of the spiral arms.
The blue ring bottom right is a #star from our own galaxy 😃 Same for the object in the 12:30 from the galactic hub of the centre galaxy
looks like an #edge_on galaxy
Wow, that is a gorgeous one!
The bright object at the bottom is a star from our galaxy, and the 'ray' extending from it is a diffraction spike (a optical artifact) 😃
I do see some spiral features 😉
2 galaxies 😃 with a third and forth to the bottom left.
#ring
It is difficult to tell without the spectra of the 3 galaxies. I do not see much interaction, so perhaps early stage?
Thanks Els, I also suspected barred, it just looked really odd!
...hub, rather oblique compared to the rest of the galaxy. ElsB?
Just got this... according to SkySurvey this is a single galaxy. We can discount the blue object on the right as it is a star, unusual...
I do not think that is a dust lane, more likely to be an optical artifact. E0 elliptical for me.
Interesting thought non- the-less 😃
Not likely - you can still see the trail on either side that has been cleaned up by digital processing.
No 😃 That is a star from our own galaxy.
Why would you think it has a quasar?
Visually looking at the image there are signs of interaction. Spiral arm at top is somewhat displaced - Tidal tail? possible #merger
Difficult to tell, not seeing much interaction. More likely chance overlap?
Looking at the image itself, cluster of galaxies. The 'closest' star is the bright blue object to the left.
I prefer to think of it as two galaxies dancing around each other 😄 #merger
No supernova 😃 A star from within our own galaxy!
Not so much a single filter, rather a slight misalignment between 3 (?) plates/filters.
It is not lensing 😃 or a star. The galaxy does have some features of a spiral, but not quite.
Arcs will be centered around the maxima of the galaxy - so they tend to be at the same distance from the hub or core. This is clearly spiral
In this case it is not an arc (or gravitational lens) - spiral arms with star formation.
There is a slight #bar - looks like the arms are settling into a #ring.
I will go with star 😃
The center galaxy looks a bit lightweight to have a satellite galaxy, with no spectra I will say chance alignment.
No, I do not think it is overlapped with a star. Possible QSO?
Artifacts again - if you look at the optical image they are not there.
Those are optical artifacts 😃
I would say it looks good #ring
@Wisi_EU: it is a matter of perspective 😃 I may need to rewatch SW this weekend, to clarify the, eeerrrr... science behind lightsabres 😃
@Wisi_Eu I would go with #lightssabre personally 😉 Sorry, needed to be done!
It is amazing 😄 Gotta love those stars!
Just viewing the image (as is) I would say yes. Nice tidal trails. Have you tried examining it closer?
I would go with #overlap. I am not seeing any interaction between the galaxies. Pity we only have spectra on the centre galaxy/
A somewhat disturbed #spiral possible #bar
I do not think it is a merger, as there is not a lot of disturbance / tidal debris in the center galaxy.
That is a star from our own galaxy 😃
I am not so sure I see any dustlanes in this galaxy. Some spiral features, and possibly a companion galaxy in the 12. Nice #asteroid
You beat me to it 😄
I would say yes, but ElsB would be able to confirm that 😃
Wow, this is a lovely one 😃 Agree with all the comments below!
Nice #ring - would you say there is also a slight appearance of a bar?
Hi Bob, it is a satellite trail.
A satellite trail 😃
Hi - I have answered you in the discussion 😃
I would go with a post merger - you can still see 2 distinct cores to the galaxy - stunning!
I have a feeling it is l ready in the collection - it is very familiar...
Looks like a possible collisional ring - will add to the collection 😃
There is interaction - so I would not rule out merger 😃
There is no need for us to comment on every image, and this galaxy is well documented 😃 Look at NED - happy hunting!
what a stunning dustlane! #double_dust indeed 😃 From this angle I would say lenticular.
The colour is a bit odd for a polar ring. Usually the polar ring is more energised and full of young stars.
I would go with tidal trail.
Not artifacts 😃 Looks like we have a inner ring around the centre of the galaxy.The dots look a lot like ansae.
No - it is a artifact caused by a passing satellite. Wish the cause was as exotic as hawking radiation!
The bright object in the lower left of the galaxy is a foreground star. The galaxy is somewhat disturbed, but not from the star
There seems to be a similar 'red' steak through the galaxy to the left (off screen) in both DECaLS and SDSS. Alignment the same. Artifact?
I would say it is likely - see the star formation in the lower left? Also light tidal debris.
Filter issue - look at the image on DECaLS skyviewer - a lot of object are similarly discoloured. Remember these are composites 😃
That is a foreground star from our own galaxy! The brightness causes oversaturation that leads to interesting looking artifacts.
Not your eyesight! This a somewhat irregular galaxy or a proto spiral, the shape is down to clumpy regions of star formation
#dustlane
Yes it is - we call them artifacts. Happy hunting!
It is most likely to be more 'accurate' for the foreground source. That is all I have time for tonight - happy hunting!
The redshift or 'z 'is calculated from the spectra, if the spectra is composed of multiple sources it is not accurate.
I am not sure where you see star formation in the red galaxy behind - I am more interested in that it appears to be a red spiral.
3/3 IOW it is contaminated, and it is not very easy to split out what emissions etc... belong with what object.
2/3 When a spectrum is done it includes all objects within the line of site of its detector. So it can include multiple objects.
1/3 Spectrum is sometimes very misleading, and can lead to incorrect conclusions 😃 Always advisable to use your eyes first ...
The colour is not real - looks like a stripe of the image was not correctly processed,or a filter was malfunctioning when it was imaged.
2/2 There is also a dark band, most likely a removed artifact going through the upper galaxy. Hence the somewhat disturbed appearance.
1/2 In this case I am going to say no, it looks like a more distant orange spiral galaxy, overlaped by a warped edge on.
Nice!
Does not look like lensing - I would say it is a more distant galaxy that is being overlapped by the closer galaxy at the centre 😃
This was the first image in a long time that made me have a second look. Foreground stars, but it did make my heart skip a beat 😃
Looks like some post imaging processing was done. The discolouration always seems to fall in linear bands. Possibly artifact removal?
You can still classify it - even with the glitch!
Nice overlap in the upper left of the galaxy.
The galaxy is an edge - on with an amazing #dustlane. The colour itself is artificial, something odd going on with the filters.
Those are artifacts from processing - you can just ignore them!
The red thing is a foreground star from our own galaxy 😃
It could also be an overlap - looking at the pixelation, the resolution is a bit low. Likely in the same cluster. Merging - not so sure.
Sadly, we have no gravitational lensing in this image 😦 The alignment is just down to chance,
Wow - stunning #bar and #disk not so sure about a ring 😃
Just by looking, I would say unconnected with the galaxies at the center. From the structure of the 'arcs' - likely processing artifacts.

just #wrong_size - the rest is unusable - but thanks for the classifications 😃
Hmmmm - as in 6 o'clock?
or possibly dislocated?
Hmmm - not so sure about disturbed. We have a third arm just inside of the outer right one. The smudge on the left may be unconnected.
Not so sure about dust... where about are you seeing it?
Looking at the Spectra on SkyServer it is unlikely to be an AGN 😦
It is very bright, so could be an AGN - would need a Spectra to verify. Nice spiral structure 😃
The brighter,rounder, more defined ones are foreground stars from our own galaxy. The fuzzier ones are other galaxies!
I will go with no gravitational lensing.
No - look at the SDSS image.
No dust lane - sorry.
A #psuedo_ring galaxy -nice!
Regions of active star formation.
Perhaps in earlier surveys with lower resolution - but I would not classify this as a LSB in DEcaLS. Clearly defined features.
2/2 SDSS has them flagged as galaxies, and they don't have the roundness of foreground stars. Not much other info - on my follow up list.
1/2 This is a bit of an odd one - the placement on the arms would suggest clumps of star formation, but the colouring is a strange...
I would not go for elliptical in this case - rather lenticular or disk galaxy.
There is a possible hint of a polar ring - that would account for the odd shape 😃
It is an artefact caused by over saturation.
Currently interacting with another galaxy, so that rules it out of the double dust category.
Hmmmm - not so sure - I was going to discount it, but it could be the angel we are viewing it. Interesting non the less.
The image is unclassifiable - it does not have the correct resolution.
Not a fan of the simulated galaxies myself.... this could be a multi-armed galaxy with star formation at the tips
#wrong_size
Remember to only classify the object directly at the center! The other objects will get their own chance to be classified 😃
It is an optical artifact caused by over saturation. The object was too bright for CCD camera!
There might be a second (more undefined) arm to the left and perhaps a third to the bottom. Well, three armed galaxies are also rare!
I am not thinking a dust lane - but rather a spiral arm 😃 Nice - single arm galaxies are quite rare 😃
The colours of the DECaLS images are different to SDSS - they all seem a bit 'whitewashed' - star formation will be more vividly coloured.
Where?
Edge on galaxy with another galaxy overlapping.Not a merger and certainly not a clump of star formation within a galaxy 😃
Could be a shell galaxy - the green and red lines are artifacts.
Sorry - where are you seeing signs of starformation? Just looks like an old elliptical galaxy for me 😃
Yes - the distortion and tidal features are all due to the merging or interaction of multiple galaxies. Lovely!
These are all just over exposed out of focus stars from our own galaxy - The Milky Way
This (and all other Illustrisi images) is a simulated galaxy - in the past you have been classifying real objects:-)
Hmmm - not so sure about lensing. The colour looks wrong in the SDSS image. Possibly just chance alignment.
The black / purple blob are artifacts caused by over saturation - you can ignore them 😃
Sorry no lensing - a group of galaxies #no_lens
Yes they are - in a case like this classify as star / artifact and move onto the next image. #wrongsize
Yes - an artifact #decalsredartifact
Only classify the object directly at the center- the other objects (ITC foreground stars) can be disregarded.
The red line going through the image is an artifact called a diffraction spike caused by the red object to the right (a foreground star).
Sadly not - this is a simulated galaxy. \the blue ring are areas of star formation.
I think the two central galaxies are overlapping and not merging - not seeing any interaction.
#blank
or #overlap - not seeing a lot of disturbance in either. Interesting either way 😃
I would go for a slight bar and spiral features - lovely!
I would classify it as one - but the sims are difficult to class 😃
The current images from the DECaLS survey are almost at an end - so at this point it is the uncompleted images...
It is a star - the missing area is due to over saturation / over exposure. Stars are closer than galaxies 😃
According to one of the project scientists they are asteroids 😃
Not boxy or a edge on - sorry!
That is a foreground star off screen to the right 😃
Once again -no need to go through old SDSS images for multiple dust lanes - we are specifically interested in the current survey. Thanks! 😃
It is a single galaxy, with a single source at the center. So I am not too sure what you are referring too? You need to be more specific 😃
Did you just get this to classify?
It is important for the Scientists to find out if the sims are valid models. What better way than to get us to classify them 😃
No, not irregular enough to be an irregular galaxy 😃
Wow - looks like a cluster. Lots of references on NED. Not too sure how the scientists would of expected to classify it?
Yup - #blank
Not x-shaped - more likely round - Sorry!
Possibly a early merger, no way to tell.
No gravitational lensing - Illustris are not capable of generating GL's. No artifacts either - this is a sim placed upon a real background.
There are tidal trails & distortion in the shape of the galaxy - but with these Illustris sims it is difficult to tell, and no right answer.
Unlikely to be gravitational lensing - more inclined to go with shell galaxy. Would need to do a bit more research - interesting indeed 😃
The red spots are foreground stars. Looks like a normal Illustris sim otherwise 😃 Happy Hunting!
Hmmm, Looks a bit too diffuse to be a star - more so in the SDSS image. I am more likely to say galaxy. Nothing on SIMBAD.
Hmmm - we would call this one #blank
I think I might go with star for the central object.
followed
Most likely an overlap - but interesting red #lens in the 11 and 9 positions of the galaxy. Will look into it more tomorrow 😃 Nice find!
Interesting image. Will have a closer look...
Wow - what an amazing merger!
It does look somewhat asymmetrical - cant see any active merging going on. Not too sure!
Not a lot of interaction, I would personally go with overlap.
It is an optical artifact caused by over saturation or over exposure by a bright object - in this case a foreground star.
The green and the red lines are both optical artifacts from when the image was captured. Could be bad pixels / dust etc.
Looks like 2 separate galaxies, the orange one on the right and the younger galaxy with lots of blue star formation on the left.
That looks like an optical artifact. Possibly an asteroid.
#wrong_size
#wrong_size
#pseudo-ring
No, the Illustris images sadly do not contain any gravitational lenses. Looks like a shell galaxy.
Popular galaxy - 62 references on NED!
Lovely #ansae and #bar too! Hmmm, looks like 2 bars at right degree angles.
nice #round-bulge 😃
Link here and zoom out.
That is one awesome artifact 😃 Check it out on 'examine' - you can see a 'reflection' of the mirrors of the telescope 😃
Try searching for a virtual observatory, such as SkyView, and read the tutorials to get started. Remember they are not affiliated with us.
Most likely an artifact since it is only visible in SDSS. The colour suggests it was just present in a single band. Check another survey?
They do, but are very rare. Sadly the redshift between the center galaxy and the upper right are very similar. Still a nice addition 😃
No not an irregular galaxy. Looks like a edge-on galaxy overlapped by a foreground star (on the right) with a non interacting galaxy at 12.
Interesting.Not as clean as the original but very nice indeed!
Excellent find 😃
I guess this is meant to simulate a polar ring
Compairing the SDSS / DECaLS images the purple blob at 4 and the green blob at 12 are the same object.
According to the experts a asteroid in the DECaLS images 😃
Definately a #edge-on, not so sure about a polar ring 😃
Another #wrong_size image 😦 Really sorry about that! Looks like the computer had a bad day when it generated these images.
That is a foreground star from our own galaxy, the colours are artifical. Happy Hunting!

#wrong_size
#edge-on galaxy
The brighter round object on the right is a foreground star, so no overlapping!

Wow- what an awesome merger, and the galaxy at 11 is the culprit of all the chaos 😃
In this case I think I would say spiral, but it is possible there could be an inner ring hidden in there!
#no_lens
We have been told artifact like that are actually asteroids!
That is an optical artifact caused by imaging. Not visible on the SDSS image. Happy Hunting!
#polar-ring #polar
No, unlikely. If the redshift is correct, the distance separating them is quite vast.
The SDSS object looks like an asteroid for me.
At the center? Either a 3-armed spiral or a disturbed 2 armed spiral

No, not sunspots. Regions of active star formation.
Um, with what?
Not a lens - I would say star formation in a spiral or ring pattern 😃
I would not call this disturbed - it has a lovely symmetry 😃
A foreground star - classify as a star / artifact and move onto the next one!
Artifacts - bad pixels is my guess. You should still be able to classify the galaxy beneath 😃
it is an artifact - it is not real, not too sure what causes it though. #decals_red_artifact
Edge on disk galaxy, slightly disturbed. No visible culprit. Hmmmm.
#overlap
#x-shaped
Depends on what feature you are looking at 😃 We have a bar, middle ring and a pseudo ring! Lovely galaxy 😃
It is an artifact. If your look at the DECaLS examiner you can see it is a diffraction spike from an extremely bright star, off screen left.
But what a stunning galaxy! Someone should nominate it for the daily Zooniverse 😃
It is a simulation - the blue bits are star formation within the galaxy.
As soon as a galaxy has any features it is no longer an elliptical galaxy. I will admit it is difficult with these sims... 😃
Could very well be - most noticeable at 4 to 7. Remember to tag it as shell_galaxy with the hashtag in front 😃
Ansae are always appropriate when there is a bar involved 😃
That is a lovely one!
Just curious, why do you think it is an AGN? just the brightness?
#no_lens - star formation.
#blank
#no_lens
The right looks like it could be a barred shell galaxy?
Sometimes with the sims it is impossible to tell! I would ignore the star on the left and just attempt to classify the central galaxy.
Sadly not - lensing is not possible in the Illustris images, the model wasn't programmed to include them.
A #blank Illustris image - looks like they forgot to add the sim 😃
Star-formation...
#wrong_size
See this discussion regarding Illustris images and gravitational lensing.
That is an optical artifact called over sataturation or over exposure. The star was too bright for the camera (the CCD)..
For galaxies this would be a good starting point: http://ned.ipac.caltech.edu/level5/Sept11/Buta/paper.pdf
Not so sure about QSO - spectra looks quite flat and uninteresting 😃
It is a foreground star from our own galaxy 😃 The center is over exposed.
#wrong_size
The bright object at 8 is a foreground star 😃
That is an artifact - imaging error.
#blank
Just coincidence - it is just by line of sight they look like they are connected 😃
They represent star forming regions in these Illustris simulated images.
The red line is an artifact - I can see several similar lines in the image. Thinking slight displacement of the image stacking.
also #wrong_size
To the right? or left? I get confused all the time 😃
Correct- very bright objects tend to over whelm the camera!
Awesome ansae! (ansae = the extended arc like blips at the end of the bar)
Yes 😃 The blue bits are regions of star formation! I think I might of commented on this 'galaxy' before - see right 😃
Not an edge-on, a barred spiral galaxy that was a bit too zoomed in. Sorry!
nice #bar with #ansae and perhaps #ring
The arms almost wrap around the galaxy so I would go with medium- personally!
Remember to only ever classify the object directly at the center. Cheers.
A foreground star from our own galaxy - the black bits are areas of over saturation.
Not an irregular galaxy - just a sim with star formation. Sorry!
No, just a single galaxy with at least 6 regions of star formation. The orange blob on the right is a foreground star 😃
#blank - classify as a star / artifact and move onto the next image 😃
It is a bar:-)
Almost edge-on or disk galaxy 😃
Aye - the algorithm gets confused with really bright objects.
A barred spiral galaxy - I am useless at telling how many arms! Gut instinct says more then four 😉
A #decals_red_artifact - it is not real just a imaging artifact 😃
#blank
No 😃 The Illustris images are sadly not capable of generating gravitational lensing.
Mmmm, Could also be a couple of foreground stars on the right. Galaxy is certainly merging, nice tidal tails!
It is a foreground star - classify as star / artifact and move onto the next image 😃
The orange objects on the right are supposed to be foreground stars.
A nice smooth galaxy composed of billions of stars!
#bar #ring #psuedo_ring
The red streaks? Yes - artifacts.
One very disturbed galaxy! Still love the dustlane, not quite what we are looking for, but will keep it in for now 😃
Not so sure about this one.... but the spikes on the right are interesting. Included 😃
Looks like we have some nebulosity 😃
Classify as a star / artifact. It is a foreground star, the dark blue area is a artifact caused by over saturation of the CCD.
No, just optical artifacts - not too sure what causes them though!
It is a #blank Illustris image - just classify as a star / artifact and move onto the next image 😃
Read comments below 😃
You can have star formation in a galaxy, without it having to interact / merge with another galaxy!
Nope - I don't think so. Looks like a smaller somewhat irregular galaxy with star formation.
A galaxy 😃 Galaxies are a lot more fuzzy than stars!
#wrong_size
It is a foreground star - the 'missing' pixels are caused by over saturation on the CCD camera.
It is an artifact caused by imaging. Looks like it could be some bad pixels on the CCD camera.
Ooops - a #blank Illustris image! Sorry!
It will get it's own chance to be classified in a separate image 😃
The red line is in fact an artifact extending through the image 😃
Irregular is a class of galaxy, so I would say no. It is a simulated galaxy with clumps of star formation
#blank
Sorry Kyle - need to #no_lens it, to remove it from the GL collection.
Wow - this could be the first #illustris_arc ! Nice find!
I would classify the central galaxy as a merger with tidal tails - it is clearly interacting with the other 2 galaxies. Nice!
The bright round object? That is a foreground star from our own galaxy. Happy hunting!
This is normal for the Illustris simulated galaxies -we are seeing a lot of similar combinations.
#wrong_size
I don't think it is two separate galaxies, to have that precise alignment would be uncanny, have you tried downloading the FITS images?
The red line is an artifact, but it shouldn't stop you from classifying the galaxy behind it! 😃
#wrong_size
#wrong_size
Classify ass star / artifact - it is a really bright star off to the right of the image 😃
#wrong_size
It is an optical artifact caused by the camera - it is not real 😃
Hopefully the other galaxy will turn up in another image! Looks like a good candidate for the DD research 😃
It is the correct size - not much else you can determine from just looking at it!
Not really - the algorithm determined the glactic center to be the blob on the left. Understandable if you look at it with human eyes 😃
Looks like it is supposed to be an overlap with a more distant edgeon.
If I was classifying I would say interaction - it will be impossible to tell for sure without seeing a zoomed out image.
They both have the same redshift - so #merger for me.
Not a merger! A stunning #pseudo_ring along with a bar.
They are clumps of star formation within the galaxy. Young stars are hot and blue. Hope this helps!
I would go with star 😃
This is a galaxy - see below 😃
What a lovely one! Nice #dustlane too!
Disturbed, lots of interaction - I would say #merger 😃
It looks like it, but it is sometimes difficult to tell with these simulated galaxies 😃
I would of classified it has having a ring too!
The blue bits are star forming clumps in the galaxy. The red objects look like foreground stars for me.
Not a lot of interaction, and only 1 has a redshift - I would say overlap.
Yes - #dustlane 😃
I would say so - remember to tag it!
I would say the orange object is a foreground star, and SkyServer agrees 😃
Stunning! and welcome to Galaxy Zoo 😃
There is a line (an artifact) going through the entire image, the bright object on the right looks like a foreground star.
Correct! A star off screen to the top left. Remember to only classify the central object 😃
The bright object with the spikes? That is a foreground star from our own galaxy 😃
#merger - looks like the top right galaxy has gone straight through the central one! #collisional-ring [25]
Yup - this is quite exciting, but, we need to find more of them!
Just posted it.
A foreground star - sorry!
In what way? 😃
#double_dust - see related post for details 😃
#decals_red_artifact
Nope - no gravitational lensing. The bright red object is a foreground star.
Yup- same goes for stars - but with new technologies / telescopes coming up the data could change. Need to be flexible 😃
Just looking at this image - I would say merger.
140 characters is not a lot to type in! Long and short - you need a spectra to record an AGN, it is not just about luminosity at the core.
Knowing the composition will allow you to make a very educated assumption about the nature of the galaxy, including about having an AGN.
Nothing to do with DECaLS! I just find X-ray easier to analyse, should be the same with optical. Spectra is the key, to see the composition.
Personally, I am now prejudiced towards x-ray 😃
A spectrograph in either optical or x-ray is efficient enough. A visual classification alone is sadly lacking when classifying AGN's 😃
Eeeewwwww - I hate spiders!
Slight shell on the lower right, just over half way to the edge.
Not likely 😃 most likely a satellite or background galaxy. A arc or lensed galaxy will be different in colour to the lens itself.
#x-shaped
lol - just a bad column of pixels on the CCD.
#blank
Cheers - any Illustris images?
Look like the Android app hasn't been updated to the latest Survey... I have left a msg for Kyle.
The large bright object at the lower left edge of the galaxy? Foreground star 😃
Star formation for me. I can see 3 similar coloured lumps in rightside of galaxy - to me they follow a spiral pattern. Would be nice though!
Usually, the cross section is really small. You should be able to find it online.
If there are multiple objects within the strip of the spectrograph, then yes, the spectra will be a combination. Not always bad.
Looks like there is tidal debris (culprit top left?), so that could skew the spectra results. Definitely not AGN Clouds.
@themis_koutras - Can we try not posting in CAPS - it is considered shouting. Many Thanks.
Double post!
No 😃 x-shape is a tag reserved for the shape of an edge-on's bulge. Examples here
I would just go with a ringed barred galaxy. Hoag Objects are formed by galactic collisions 😃
just tag them as #blank - it will help the scientists in the long run 😃
I am going to go with artifact - like you said it is way too straight to be gravitational lensing 😃
#wrong_size
I am going to go with overlap - not much distortion in either galaxy. Lovely image!
#blank
It has a redshift of 0.07, so it is not local. Elliptical Galaxy for me 😃
They have a very symmetrical structure, so I would not class them as tidal debris. I would personally say spiral arms. #bar #ring #resonance
wow - an inner and outer ring. #ansae also - lovely!
A very luminous object - I would go with a foreground star.
Looks like the image was incorrectly sized - I can see how it will be really difficult to work out what to classify in this one! #wrong_size
My point exactly! Keep things simple!
Not that I am saying this is an elliptical galaxy - but each to their own:-)
For clarification - ETG = Elliptical galaxy - and that is an assumption. "Engineering Technology Group" seemed unlikely as an alternative.
Hi Jean, please try not to use acronyms that have not been commonly used on here before - they are not newbie friendly 😃
Just tag it as #blank and move on 😃
What a #dustdane! In fact is that a double? or just a reflection? Will flag it up.
#wrong_size too!
😃 October?
Perhaps 7 ????
Maybe 5 or 6? But I am useless at counting arms. Perhaps someone has a better idea?
Another incorrectly sized image #wrong_size
To create a link to another image you just need to put in the ID like so: AGZ0009wd5 - the link is automatically created.
Shell galaxy with star formation for me.
#merger for me 😃
Correct! It is a foreground star!
I would go with smooth - there are no features - nothing to indicate it is a disk. Just my personal opinion.
#decals_red_artifact
#decals_red_artifact ?
#decals_red_artifact
#decals_red_artifact
We should tag these with #Decals_Red_Artifact
Thanks! I will have a look and get back to you in the thread.
The 'blue stuff' are regions of star formation. Looks like a satellite galaxy.
At the centre? No, a edge on galaxy 😃
I would go with all of the above 😃 #merger
Another DECaLS red artifiact - we really should collect these!
What a stunning galaxy! By 'stain' do you those dark patches?
See discussion on the right 😃
Yes, looking at the colour and shape I would also say artifact.
No gravitational lensing 😃 I would go with a loose possibly 3 armed spiral. Thanks for your help!
Looks like a late stage merger to me. I am sure I can see 2 slightly distended core on the right. Anyone else?
Looks like it 😃
#zgotw #dailyzoo 😄
Yes - I would go for an #x-shaped bulge.Nice one!
2/2 team do their work and when the result are presented, comment on it then. Also consider that your words may influence other volunteers.
1/2 @JeanTate - yes, but you made a statement ("another unreal sim") without having analysed the data. What I am saying is let the science
@JeanTate - let them analyse the data before making a judgement 😃 If you feel different - there is no reason for you to classify.
The apparent increase in QSO's may also be a side effect of deeper imaging - not necessarily QSO's - just more photons being captured!
...and that is exactly why we are classifying these simulated images, so they can compare the data against real galaxy classifications.
Sorry I am not seeing any gravitational lensing in this image.
No it is not - in the Illustris images blue indicates star formation. #no_lens
Hmmm - I do see a ring of sorts, does not have the morphology of a pseudo ring - no so sure what I would call it.
Looks like a spiral arms wrapping themselves around the galactic core for me 😃
The blue fuzziness indicates regions of star formation in these simulated galaxies - hope this helps!
Aaahhh - good to know!
The orange object below the galaxy? more inclined to go with foreground star 😃
The blue regions indicate star formation - interesting how they follow a spiral pattern in this simulation 😃
Star formation apparently! Cant help but remark on the shell like structure once again!
Hmmmmm - star formation is often triggered by merging. They seem to share the same halo - early stage merger for me 😃
@wtaskew - Just for interests sake 😃 How do you define a gpair as opposed to a merger? Previous classification? or visual inspection?
Love that - swagalicious 😄
Also, some disturbance on the right of the smaller galaxy.
Aye. You can see a tidal trail from the smaller galaxy on the right, crossing over the top to the left of the larger galaxy.
Yes - I know the colour of the images are different - but the structures is quite similar 😃
I was almost thought this was a IIlustrius image....until I looked at the tag. Awesome 😃
No lensing - looks like we have a dustlane and a very strong #x-shaped bulge. Certainly very interesting 😃
No - I don't think so, but I am sure @kwillett would be able to confirm 😃
For the bright purple bit, I would say artifact. There also seems to be a smaller, greener line beneath it - @kwillet ?
Yeah - I would also go with merger - nice tidal debris
Possibly a simulated Shell galaxy?
Not so sure this would be classed as an irregular galaxy - seems pretty regular 😃
Another DECaLS star that gatecrashed the dataset 😃
Not sure - I will have to research what GL's would look like in in DECaLS images. Will need a few days.
cool - will spread the word!
@kwillet - how do you want us to tag these ones? Blank may also include previous surveys...
#blank_illustris
It is an overexposed foreground star - are you using the mobile app to classify?
It is one of the illustris galaxies - they all seem to have a slight blue discolouration near the nucleus.
QSO = Quasi Stellar Object
I would love to know why do you think it is an AGN? Just the brightness? or did you find a corresponding spectra? 😃
As all these images are classified by multiple volunteers it is highly likely the disk galaxy was picked up and correctly classified!
Foreground stars that the algorithm mistook for galaxies! Classify as a star / artifact. Happy Hunting!
The smudge at the center is indeed a nondescript galaxy, the ball on the left hand side looks like a foreground star. Happy Hunting!
#no_lens
#no_lens
#no_lens
#no_lens

All foreground stars - to be honest, comeback tomorrow and classify - we will have a new survey 😃 Way more interesting!
All fore ground stars 😃
#no_lens
#no_lens
#no_lens
#no_lens
#no_lens
Read below - not a gravitational lens - just foreground stars masquerading as one!
Correct - all of the objects in this image are in fact foreground stars.
An irregular galaxy with intense regions of star formation.
This is a galaxy, but looks like the filters were slightly misaligned - hence the two toned colour effect.
Yes - foreground str from our own galaxy.
Most definitely a #bar - nice #ansae at the ends 😃
Hmmm,don't think so - perhaps spiral arms? The resolution of the galaxy is not that good so it could just be empty space.
I am going for galaxy on all accounts - nice cluster 😃
Classify as star / artifact - an exposure from the early evening when the sky was still too bright to image. Happy Hunting!
Thank you 😃
Yup- agree
You are correct! All the objects arein fact stars from our galaxy 😃
Nope - an irregular galaxy with star formation. A single galaxy - no merging.
No, most likely a starforming region within the galaxy. We would see more disruption if this were a merger 😃
Go with your initial instinct - there is no wrong answer 😃
Not an irregular galaxy - I would go for spiral features,barely noticeable nucleus / bulge.
Welcome 😃 Classify as a star / artifact, all theobjects are out of focus, over saturated foreground stars. Happy Hunting!
Yes 😃 Artifact - all these objects are out of focus foreground stars.
No signs of a ring - a edge on galaxy slightly warped
Foreground stars - not necessary to tag them as 'bugs' - just classify as stars / artifacts and they will get removed from the dataset.
Correct - all of the objects in this image are foreground stars. Classify as star / artifact and move onto the next image.
If you check the redshift (Z) of both objects, you can estimate whether the objects are at a similar distance. Have you had a look?
Always classify the image directly at the center - in this case the smaller purple blob on the left (which happens to be a foreground star)
Not a galaxy- a foreground star from our own galaxy. The weird colours are due to over-saturation.
Not a nebula - a galaxy with rich starforming regions 😃
That is a foreground star from our own galaxy - they tend to get in the way when we are observing much more distant galaxies!
The telescope wasn't tracking correctly - hence the 'double' objects. If the exposure was longer we would see trails.
Not a sattelite trail - a diffraction spike from a bright foreground star off screen to the left 😃
I would say so 😃 The central galaxy is in the process of merging with the orange galaxy in the top right.
Hmmm, difficult to tell in this image. We do have a lot of stars, but the orange blob in the centre looks like a galaxy to me.
Lots of star formation - so still in the process of forming. You can tell by finding out what atoms and elements are present in the galaxy.
No worries 😃 Lots of people will classify this image, so I'm am sure it will be flagged as having a bar. Thanks for your help!
Neither galaxy has a spectra associated with it, so visual inspection is most likely the extent of the investigation.
😄
Always classify the one directly at the center, in this case it was the tiny one you classified 😃
#merger for me
I would go with 2 galaxies merging - stunning!
Out of focus foreground stars
A stunning 2 armed barred spiral - nice!
Hi @jdmonk - It is not a galaxy, rather out of focus foreground stars. 😃
Always classify the object directly at the center - in this case it is most likely a foreground star 😃
They are out of focus foreground stars - classify as a star / artifact and move onto the next image 😃
Instructions here
That is a diffraction spike from a bright foreground star off screen to the top. Have a look on SkyServer for the zoomed out image.
Classify as a star / artifact - this is a star from our own galaxy. The weird colour / shape are imaging errors.
Could also be an #overlap - the photoZ of each galaxy indicates they are quite distant from each other.
Out of focus foreground stars.
A central galaxy overlapped by foreground stars 😃 Stars tend to be whiter and more round in the SDSS images. Hope this helps!
I would go with foreground star 😃
Classify as a star / artifact - it is a foreground star from our galaxy. It is also out of focus and misaligned.
Classify as a star / artifact 😃 Imaging errors from the edge of the observing field.
Yes - a stunning merger. Have a look on SkyServer for the zoomed out image. (link also in the comments below)
The bright one lower left? A foreground star from our own galaxy 😃
Imaging errors (could be equipment or environmental) - just classify as star / artifact and move onto the next image.
Correct!
Edge of one of the observing stripes - mark as star / artifact and move onto the next image 😃
Not a lot of interaction, so I would go with #overlap. Lovely edge-on!
Looks like two galaxies merging 😃 Lots of star formation too!
Aye - an artifact. Edge of the stripe / field.
The FAQ's are correct - if there was a green blob along side the other two then we may consider it an asteroid.
Not an asteroid - it is an artifact. If you look on SkyServer all the objects close by have similar errors.
No gravitational lensing at 5 - that is a edge-on galaxy.
An artifact caused by imaging / processing errors. Classify as a star / artifact and move onto the next one 😃
Also, I am looking at this image on my mobile - don't have access to NED/ SkyServer, so can't access additional resources.
Yup... agreed. Not convinced it is an arc, but the curvature is good. Concerned about colouring - should be more blue or possibly red.
The smallest of the 'cores' @ 2 is a foreground star. The others are ansae - star forming regions at the ends of bars.
😃 agree
@fishpond you need to include a word along with the hashtag for it to be useful 😃
Nope - not an irregular galaxy.
où?
I don't think so - the PhotoZ is quite different and no interaction between the two. A accidental line up 😃
Just classify what you see 😃 There is no right or wrong answer. Personally - 2 armed barred medium spiral
Correct! A edge-on galaxy at the center and several foreground stars.
It is an artifact caused by oversaturation. Have a read of the FAQ thread for lots more info on various artifacts etc..
Looks like a resonance ring and a bar - nice!
Yes:-)
The blue one - you can check the redshift values on SkyServer. They actually are quite close - relatively speaking 😃
WOW indeed! #ZGOTW
Usually, yes - blue galaxies tend to be closer to us, red galaxies are futhur away. Not a lot of interaction.
Not a edge-on galaxy - a disk galaxy with an awesome #bar! Nice!
I see what you mean - difficult too classify - I would of gone for smooth, in-between myself as there are no clear features.
No need to flag it here - just classify as star/artifact and move onto the next image! It will get removed at some point 😃
That is a foreground star from our own galaxy 😃 More info
here
Not really - it is an artifact, so it is the result of imaging / processing errors.
Could either be a satellite galaxy of the larger central one or a foreground star. SkyServer thinks it is a star, but too diffused for me.
Hi @khutzel2 - this is a foreground star. Read below for more info.
SkyServer is not always correct - that is we come in 😃 This is a foreground star, no info on NED
We do have a edge on galaxy at the center, but the bright green object on the right is a foreground star.
3/3 .. it is the scope not the object that has moved. Best I can explain in 140 characters or less.
2/3 .. blue blobs in an image. It is the same object just captured in a different position as it moves. Ditto for misalignment, just ...
1/3 Yes - 'cause each of the filters are stacked on top of each other. The same way you would see a asteroid as separate red, green and ..
As for the colours - caused by oversaturation and stacking / filter issues - the colours are not real - they are added afterwards.
No way to tell without knowing the redshift of each of the stars - could just be coincidence down to line of sight.
I would not go with round - the galaxy has faint spiral arms. Disk / spiral galaxy 😃
Also a slight misalignment between the 'r 'i and 'z filters - look at the raw images in GZ examine.
Read below 😃
It does look like it - but no 😃 These stars are way fainter and in a different part of the sky. A coincidence 😃
I would go with: features, not a edge on, no bar, not a spiral and possibly something odd. Just do the best you can on what you see 😃
An #irregular galaxy with clumps of starformation.
A very bright foreground star 😃
Wrong colour for a supernova in these SDSS images - they would be a intense blue / green.
Just a out of focus foreground star with optical artifacts. Not a spectrum, sorry.
It is a galaxy with a dustlane and regions of active star-formation. Read below for more info 😃
The filters are slightly misaligned - so the red and blue images are not correctly stacked.
No:-) starformation
The dark spot is an artifact caused by oversaturation. The CCD camera got overwhelmed by the brightness of the galaxy 😃
Artifact for me - foreground star that is out of focus.
Intense regions of star formation - otherwise known as starbursts 😃
#no_lens
SkyServer has a spectra of the buldge - star forming region. Looks like quite a young galaxy.
#artifact
The object on the left is a foreground star - the black line is an artifact caused by oversaturation. Happy hunting!
Only visible in the 'r filter so I am going with artifact.
#artifact personally - there is not a lot that could be determined from this object 😃
2/2 We have a galaxy at the center, but the white / blue objects are foreground stars - I would classify as a smooth / inbetween galaxy.
1/2 First off - welcome to the Zoo @oldgeorge ! There is no such thing as a incorrect answer, the answer will balance out in the end 😃
Overexposed and out of focus foreground stars 😃
Not very disturbed, so I would be likely to say overlap.
Not a galaxy 😃 A over exposed foreground star!
Yes - I would say that most of the objects in this image are foreground stars 😉
Sadly it is not a merger / gravitational lens, and the galaxy does not look too disturbed. We have a lot of foreground stars in the image...
Not normal - an artifact caused by imaging / processing errors. BTW all the object in this image are foreground stars.
At the center? or too the left?
I would be lying if I said I understood all of it either 😄
Nope - a star /#artifact
My bad - I should of said 'quasar' not AGN in my previous posts - I was responding to the previous comments.
Um, are you asking a question? or saying the previous poster was wrong?
Good to have you back 😄
Does anyone have the original source classifying this as an AGN?
Hmmm - Having just read the paper myself - looks like this is not an AGN but a NELG (narrow emission-line galaxy)
It is quite likely 😃 We are almost coming to an end with the DR8 SDSS images - but you are the first one to comment on it!
Yes - I would agree- foreground star in the line of sight of the galaxy.
The green object is a gas cloud on the outskirts of the Orion Nebula: Link to SkServer where you can zoom out.
A galaxy - but with several foreground stars obscuring it 😃
These are in fact foreground stars from our own galaxy - the weird colour and oddness are all optical artifacts. Classify as star / artifact
Correct!
Yes - most certainly a foreground star 😃
These are all foreground stars from our own galaxy - the strange colour are optical artifacts.
A galaxy - does not have the electric colouring of a voorwerp.
A foreground star.
Most likely 2 foreground stars - the weird colour are downto artifact from imaging / processing.
Yes:-)
I would go with a lovely spiral galaxy!
Not a merger but it is an artifact! Three foreground star, the strange colors are artifacts.
at the bottom left of the image? or at the central galaxy? Need to know, so I can analyse what you are referring too 😃
An artifact - foreground stars mixed with imaging errors 😃
Certainly has the luminosity and definition of a AGN, but still trying to find a spectrograph to confirm...
Also has a bar and undefined spiral arms - so it is definitely not an elliptical 😃 So no need to use the hashtag #justsaying
Another galaxy - looks somewhat edge on. Also has a diffraction spike going through it from a star off screen to the right.
On the right? There are several little things in the image 😄
...for a zoomed out image. link - after clicking select 'get image'on the left.
They are optical artifacts - a diffraction spike and arc caused by a bright star off screen to the left. See the link in the next post...
The green line is an artifact caused by a satellite - as it only gets captured in a single filter we only see it in a single colour! 😃
The object at the direct center or the blue object slightly off center to the left?
Not an artifact 😃 This is in fact a galaxy - the filters might be slightly misaligned, but you should still be able to classify it.
The blue dots on the immediate center left are star forming regions in the spiral arms. The lower blue white dots are foreground stars.
Yes 😃
More common than we would like - out of focus foreground stars. Caused by imaging issues on the scope.
A #collisional-ring galaxy - nice! [2]
Sorry, not an irregular galaxy. A bunch of foreground stars in the line of sight of a galaxy.
The top left objects are stars from our galaxy- the effects are optical artifacts.The galaxy at the center is more interesting-double nuclei
Foreground stars from our own galaxy.
Not so sure about merger! The two galaxies look unconnected to each other and the photoZ is of the two are quite different. Sorry!
The fuzz balls are all foregrounds star - just classify as a star / artifact and move onto the next image.Thanks!
All the objects in this image are stars from our galaxy. Classify as star/artifact
The red object is a foreground star from our own galaxy - so unrelated to the galaxy at the center 😃
#artifact
Skyserver has it classed as a foreground star and just looking at this image I would agree.
The blobs are areas of intense star-formation or starbursts - so yes, please do tag it as interesting!
Sorry - not an Irregular galaxy - I would go for a two armed spiral.
Not a comet - a young edge-on galaxy with star formation. Nice!
Not so sure about a ring 😃 Most likely spiral arms folding back on themselves. You could tag it as a #pseudo-ring
#no_lens
#no_lens
That is one seriously disturbed galaxy! So I would say it is connected 😃
#imagesizewrong
This is a real galaxy - the 'pixels' are background noise. This galaxy is 440,700,000 light years away 😃
Yes it does! It might be easier to make out if you try to use the 'invert' feature 😃
We are all newbies once - and welcome to the Zoo 😃
2/2 .. and take it from there. Did you try the 'invert' feature when classifying? I find it helps a lot!
1/2 Just looking at this image and not SkySever, I would not classify this galaxy as a edge on - I would select 'features/ disk'...
It is an artifact from when the image was captured / processed. It is not real 😃
#imagesizewrong
It looks like an inner ring close to the nucleus of the galaxy.
The black line through the galaxy is an artifact - caused by multiple fields being put together to create a single image.
One of the more difficult 'u band images I have had to classify...
This is one of the images that got zoomed in too much - really sorry 😦 #imagesizewrong
Looking at the spectra it doesn't look likely - it does not have the high emission line of H alpha that we would expect from AGN's
What object do you think the central galaxy is merging with? I am not seeing any interaction myself 😃
The line is an processing artifact - it is the point where two SDSS imaging fields have been joined 😃
Looking at SkyServer I would say it is most likely a foreground star. Supernovas have a very distinct colouring.
What do you mean by bug? Or are you referring to the artifact going through the image?
Both look like overlaps for me - no interaction, they just look they are connected by line of sight.
2/2 assume you are talking about the central object. If you are talking about the round blob @12 at the top edge - it is a foreground star.
1/2 Can you please be more specific about the object you are referring to? Unless you make reference to the position of the object we will..
#barred #spiral
#imagesizewrong
You can get blue ellipticals - but this is not one. Ellipticals are void of all features - this galaxy has clear spiral features.
No - we can see some faint spiral features and possibly a bar, so I would go down the 'features / disk' route. Ellipticals have no features.
It is one of the zoomed in images - #imagesizewrong
#bar #spiral
Wow - the bar wasn't even visible in the 'u band - nice!
Nuclear rings are close to the core of the galaxy and are within the ends of the primary bar. This is not one - would go with SB(L) myself
@floortap - I would have to say no merger. This galaxy has most likely been merged in the past, but it starting to settle down.
No worries 😃
@crazy_hair2000 - yes this would still be considered a spiral. The "gas" on the left are still stars that are part of the galaxy.
Not so sure about merger. Do you have the object ID of the galaxy you think it is merging with - so I can have a closer look?
Not overexposed just viewed in the 'z filter. This would be light that is radiated in the infrared spectrum, objects would look brighter 😃
#bar
Are you using the android app to classify? We finished classifying the hubble images a few weeks ago.
Only ever classify the object directly at the center, it's OK to chat about other objects here, but when classifying - center object only!
It is a galaxy 😃 Looks like it has a bar and spiral features. Not much else you could tell from this image.
That is an optical artifact - it is not real. Looks like a bad column on the CCD camera.
Correct! They are both foreground stars - not connected with the central galaxy 😃
I can see faint spiral features, so I would say no. Have you tried flicking between the default and inverted image? I find it helps!
Try flicking between the inverted and default image - it can make it easier to determine features. I find it helps a lot!
Just try your best - it is your classification we need 😃 I would go with barred spiral, disturbed.
It is definitely a galaxy - it is more obvious when viewing the image in colour 😃
Here you go - link to SkyServer
The bright well defined dots? They are foreground stars from our own galaxy 😃
#imagesizewrong
#imagesizewrong
Looks like something went wrong when theimage got generated #noimage
It is a galaxy - made up of billions of stars - if you scroll down you will see the link to the colour image 😃
I would also go with overlap - no visible interaction.
2/2 ... disturbance or interaction between these galaxies. Most likely an overlap.
1/2 ...You could try looking up the redshift of both galaxies. If they are similar then there is a chance they are interacting. Not much ...
Yes! same galaxy just viewed in a different wavelength!
Nice bar 😃 No, it is not a lensed galaxy - spirals do not usually have the mass to cause gravitational lensing.
#barred #ring
Nice #pseudo-ring
#merger same redshift at z~0.37
#imagesizewrong
It is an artifact - most likely a satellite trail.
Neither 😃 We are only viewing this galaxy in a single band or filter, so it can be difficult to make out features. Bar and spiral for me
Nice #bar ! Very subtle spiral features.
Link here - looking at it - definitely foreground star 😃
Just looking at this image I would say a foreground star or a clump of star formation. Have you had a look at the Skyserver image?
Much the same link here
Just looking at this image I would say bar, resonance or inner ring and a outer psuedo-ring. Let see what it looks like on SkyServer 😃
#barred #spiral
Went for edge on for this one - On SkyServer it looks like a loose spiral with a halo 😃 Apparently that is a steller nucleus at the center
Spiral features in the inverted image
Looks like we have a bar - that could give the appearance of some disturbance. Nice 3 armed spiral!
Follow the instructions here to see the image on SkyServer 😃
No worries 😃 If you look at the colour image it is a spiral galaxy - but it the black and white images that we are collecting data on.
Sadly not 😃 It is a galaxy viewed in a single wavelength / band so it is quite faint. Just try your best to classify it!
Lovely example of ansae at the ends of a bar! Info here
#barred #spiral #z_band
Just classify the one at the center 😃
It is a spiral galaxy viewed in the 'u band - in these images it can be a bit tricky to make out the features - just do your best 😃
@Danute - can you please clarify why you think the central galaxy is boxy? and also where you are seeing the lens / arc Cheers 😃
Not an irregular galaxy - stunning 2 armed spiral 😃
Not so sure I would go with irregular for this one - the single band images can be a bit misleading.
Looking at the SkyServer image it looks like a foreground star - it doesn't have the colouring of a SN as usually seen in SDSS images 😃
#imagesizewrong
See discussion on the right 😃
Just try your best - there is no wrong answer 😃 I Would of classified it as a barred galaxy - possible ring.
double nucleus?
#imagesizewrong
I am going to go with #overlap 😃
Not a jet 😃 This looks like one of the old Hubble images - all the objects are galaxies 😃
Not so sure about smooth - can you see the 'tips'of the galaxy going in different directions?
#star_formation 😄
No merger - the bright spot on the right is a foreground star - but what a stunning barred spiral galaxy at the center!
I am not seeing a merger - are you talking about the clump in the lower left of the galaxy? Region of star formation 😃
Hmmm,not so sure I would go with irregular. Nice spiral structure with clumps of star formation.
Cool 😃
Once again - do not be influenced on what you see / expect to see on SkyServer. We want to know what you observe on this image. 😃
Not necessary to tag objects you see on SkyServer - this is a separate survey 😃
What it looks like on SkyServer is not that important - concentrate on the image you get to classify 😃 Thanks!
blog here
Classify the image as you see it in black and white - not what you see in colour (on SkyServer)! There is an important reason why 😃
SkyServer is not always right - it is nice as an additional resource - but it is not infallible:-) Looking at the spectra - same redshift.
Welcome 😃 Everyone is new once - and there is no such thing as a mistake! We all work together in the interests of science 😃
At the center? That is a galaxy 😃 They are rather fainter when only viewed in a single filter - in this case the 'u band
Read the discussion to the right 😃
Not really 😃 Spiral arms can be rather loose. The galaxy does seem to have a bar - nice!
2/2 ...or disk' and 'No, it is not an edge on' you would then get asked if it is a spiral. Hope this helps 😃
1/2 There is no way to redo your classification - but not too worry as it will get classified by others. If you selected 'features...
Classify the image as what you see here - not what you see on SkyServer!
It has a bar and possibly a ring. Start with features or disk and take it from there 😃
I am only seeing 1 spiral galaxy or do you mean the number of arms??
The object to the right is a foreground star.
I would agree with you - there does seem to be a slight bar running right to bottom left.
A foreground star 😃 Flagged as such on SkyServer, also not the distinctive colouring of a SN. Happy Hunting!
I am really enjoying the single band images - and there is an important reason why we are classifying them 😃 More details in the blog.
I don't think it is a merger - we are only viewing these images in a single band or wavelength so that could account for the strangeness.
Pseudo-ring galaxy - http://ned.ipac.caltech.edu/level5/Sept11/Buta/Buta6.html#6.1
In the bottom of the galaxy? A foreground star from our own galaxy.
The image was incorrectly sized - Sorry! Classify as star / artifact and move onto the next one 😃 #imagesizewrong
This galaxy has a lot of active star forming regions - I would not go so far as too say disturbed, early proto spiral perhaps?
I would say it is a single barred spiral galaxy - possible pseudo-ring?
That is one possibility, or it could be spiral arms backing over each other. Looking at the galaxy I think that is more likely.
Really difficult one to make out - even using invert!
A barred spiral galaxy for me, but it is your choice that is important 😃 How did you classify it?
Also, please remember to only ever classify the object directly at the center!
A galaxy with spiral features - try flicking between the default and inverted images when classifying to get a better idea on the shape.
No, foreground star from our own galaxy 😃 Also remember to only classify the central object - this time it is nothing - so star/artifact.
Read below 😃
They are dense regions of star formation - young stars are hot and blue - nice!
I am also more inclined to go with #overlap - one of the more stunning ones #zgotw
One of the nicer ones I have go so far. Possible low grade arc and counter. Adding it to the #lens collection for a closer look.
Do not get hung up on redshift or colour. The colour in these is not real, and there is a lot of processing going on.
Once again - not an elliptical galaxy 😃 Too many features - possibly early spiral. Elliptical galaxies are featureless. Thanks!
No! Not an elliptical! Whenever you see any features (such as arms) - classify it as such - not as a smooth galaxy. Thanks 😃
Most likely an unrelated galaxy - difficult to tell - Sorry!
2/2 ... So I would classify it as a galaxy with features and take it from there. Some might say clumpy, but I am not so sure 😃
1/2 Not a relavistic jet - at these distance it would be impossible to see one. It does not have the colouring / intensity of a quasar...
It is a galaxy 😃 We also have regions of star formation embedded within it and the beginnings of a core and spiral arms - Nice!
Sorry - not convinced it is a merger. None of the galaxies are interacting.
Hmmm, not so sure... there is no counter image and not enough arcing for my liking. The blue blob at the bottom is unconnected.
The dark spot is a optical artifact caused by oversaturation. In other words the object was too bright for the camera.
I am really sorry - no arc. Spiral arm.
Is what common? The green and blue splodges in the image, or the galaxy at the center? 😃
Not a smooth galaxy! It is displaying clear spiral features, along with active bands of star formation. Hmmm, colouring is a bit odd.
Still possible to classify - just takes a bit of patience 😃
Yes, it is a distant galaxy, as for the bright center - the galaxy most likely hosts an AGN (Active Galaxy Nuclei) aka a black hole 😃
It certainly looks disturbed! Not so sure about a merger at the center. As mentioned below, could be interaction with the top right galaxy.
Not so sure about bulgeless, but it has been flagged as a possible weak AGN - mentioned in this paper
No supernova 😃 Just a single foreground star that was too bright for the CCD camera - all the odd shapes / colours are optical artifacts.
The green splats are artifacts caused by optical strikes / bad pixels etc... that did not get removed when the images were processed.
Top left? A foreground star from our own galaxy.
Answer below! All the green and blue dots are unremoved artifacts from the imaging process 😃
The three galaxies are unconnected to each other - certainly not a clumpy object 😃 Happy Hunting!
I would go with overlap - no signs of disturbance. Also, the photoZ of the orange elliptical indicate it is a lot futher away.
2/2 impossible to see stars behind galaxies billions of light years away. I would say this galaxy is host to an #AGN.
1/2 This is a galaxy - and no, that is not a star behind 😃 All the stars we see are foreground stars from our own galaxy so it would be ..
I don't think we have any overlapping stars - just one clumpy galaxy 😃
It is an irregular galaxy - nice star formation going on.
Yes, I would classify it as such.
I am really sorry but it is a foreground star - NED confirms.
Not a star - a galaxy 😃 Most likely containing an AGN
I would agree - what a beauty!
Just classify as star / artifact and it will eventually be removed from the dataset.
The brighter blue area in the galaxy are regions of dense star formation - young stars are hot and blue, hence the colour of the galaxy
No interaction - so they are not merging. I would not consider this an overlap as the galaxies would need to be superimposed over each other
I would go with a 2-armed spiral with star formation. No signs of merging - sorry!
They are all artifacts - they follow a broad linear pattern that has only partially been removed.
That is an artifact - most likely an optical strike that has not been removed.
That 'blue' blob is orange in the image in the letter, so not related / a counter image of, the 'arc' at 12. Arclet at 8 more interesting.
At the edge of the image? Unrelated - way outside the Einstein radius.
Not so sure about a bar - but 2 armed spiral sounds good 😃
😃
Hi and welcome @O.B132 😃 Sorry- no lensing - two galaxies (a spiral and a edge on) starting to interact - lovely image!
Without having the adjacent image to look at, one can't say for sure. Takinginto account colour and shape - I would go with another galaxy
Edge of the imaging field - as the images we classify are composites from several different filters the edge can differ from 1 to 1.
Hi @koedooder 😃 Can you leave a bit more info eg. arc / quasar / where in the image. We need this info when we pass info along... Cheers.
I am going to go for no with this one sorry! #no_lens
At the center? Looking at the colour it is way more distant than the blue fluff just below it 😃 Overlap.
This is an almost edge on galaxy with star formation and dust lanes. You can see the spiral arms - stunning!
From this letter: http://iopscience.iop.org/1538-4357/600/2/L155/pdf/17385.web.pdf
Well, it was considered a possible candidate back in 2003 - but the note relating to it is not very convincing "blob + possible cluster" 😃
Hmmm - not enough arcing for my liking - but I will have a closer look.
No - a satellite / companion galaxy to the central one 😃
No - no voorwerp. Sorry!
diffraction spike
No galaxy - the algorithm that chooses the images for us to classify got confused by the diffraction spike from the bright star off screen.
All artifacts - imaging errors that were not removed during the cleanup process.
This is a galaxy - very fuzzy. I would most likely classify it as smooth and inbetween.
Yes - Looks like we all have a #bar and a bulge 😃
An artifact that was not removed from the image. Most likely a particle strike.
The edge-on is not showing any signs of interaction, so I would personally go with overlap.
It is at the edge of the field that was imaged 😃
Not a supernova - most likely a foreground star from our own galaxy 😃
I would say it has spiral features, and go down that classification route 😃
No planets would be visible at these distances 😃
The central object is an elliptical or smooth galaxy, not a star!
Looking at the galaxy the blue arc are more likely star formation than lensing 😃
At the center? It is a smooth inbetween galaxy 😃
As pointed out - not a star. I would go for a round elliptical galaxy (E0) myself 😃
Read below - an artifact caused by over saturation 😃
Broad line refers to the type of emission lines we see in the spectra. I am sure you have asked this / made reference to this before???
For others reading: cosmic ray strikes can present themselves in a straight line.
Just concentrate on the object at the center and try to ignore the artifacts 😃
All the bright red / green / blue spots are optical artifacts - cosmic ray strikes / bad CCD pixels / edge of chip etc.
Looks like a single clumpy galaxy.
Bright spot @10, left spiral arm? Most likely a foreground star. SN tend to be bright blue/green depending on what survey you are viewing.
Most likely star formation - does have the vivid colouring one would expect from a voorwerpje. Sorry!
In a short answer, no. That is why lenses are so important - a lot of a galaxies mass is not visible, so we can only make estimates.
Still only a candidate - can't find much else on it.
Not disturbed - a fuzzy spiral. Not much else we can tell from the image.
Sorry- not gravitational lensing. The arc would have a different colour from the lensing galaxy. Star formation with spiral characteristics.
2/2 is more important when visually indentifying a lens candidate. Followed up by modelling and spectragraph.
1/2 No, not really. It is more the mass of the galaxy and not necessarily the size that determines lensing. Looking at the shape / colour...
@ramberts - kpc (kilo parsec) is a unit of measurement, in this case it is the size / diameter of the galaxy.
I will add it too the #lens collection so I can have a closer look when I have more time. It does look a bit arc like, but I have concerns.
Yup 😃 Always remember to only ever classify the object at the center 😃
They are all imaging artifacts - the colour and shape are a clear give away!
Sadly not 😦 A clumpy galaxy - voorwerps have very vivid colours - usually deep blue / green.
No interaction between the 2 edgeons at the center, so I would go with overlap. Remember to only ever classify the galaxy at the center 😃
A foreground star from our galaxy - did you just get this using your desktop browser? 😃
BTW welcome 😃
Possibly a disk galaxy seen slightly off axis, so instead of viewing it as a edgeon, we get to see spiral features at a small oblique angle.
I am going to go with particle strike - artifact. Sadly not available in 'examine' in the different filters.
No, not a line of stars - a diffraction spike from a star off screen to the left. Unrelated to the galaxy at the center of the image 😃
Not a comet 😃 A edge on galaxy - happy hunting!
Same cluster as AGZ00085fg - GOODS full-depth
Same cluster as AGZ00087r5 - CANDELS 2-epoch
It could be an artifact that has only been partially removed or just noise 😦
A foreground star with diffraction spikes and other artifacts associated with over saturation 😃
There is no way to go back and correct a classification - we want you first impressions! As for a bar, I would of personally said no 😃
Sorry - too diffuse to be lensing, also would expect the shape to be more centred around the galaxy, with the galaxy having a greater mass.
The line? or the blue clumps in the galaxy? The line is a diffraction spike, the blue clumps star formation 😃 Hope this helps!
I would classify it as such as it could also have a dustlane - you also could of gone with smooth cigar shape - really up to you!
Same galaxy as AGZ00082vd
Same galaxy as AGZ00082vj
Awesome diffraction spike from a bright star off screen 😃
Yes, this sometimes happens 😃 An algorithm chooses the images that we classify - It tries it's best, but occasionally gets it wrong!
Difficult to say - hardly any interaction, so I personally would go with no 😃 Hope this helps!
Artifacts 😃 Either particle strikes that have not been removed, bad pixels on the CCD, or less likely - asteroid (due to 'linear' pattern)
See post by @C_cld below - overlap, not a dust lane - Sorry!
#no_lens
#no_lens
#no_lens
#no_lens
#no_lens
Bit concerned about the spiral features on the left and the diffuse nature of the lower arc - but still nice 😃
I agree possible #lens candidate 😃
Yes it does 😃
No - not an irregular galaxy 😃 A barred spiral with star formation
Not lensing - mass of the galaxy is on the light side 😃 Nuclear or inner ring is my guess 😃
Not an artifact - look like a very faint galaxy at the center 😃 The blue dot on the right of the galaxy could be a star or star formation.
Read below 😃
...and this object is a galaxy - the pixelation of the image makes it difficult - but just try your best 😃
Just remember - classify the object on what you see - additional information is not necessary when classifying 😃
No lensing - sorry! The blue bits are regions of star formation.
stunning #edgeon
@adithya No. Not an Irregular galaxy. Also this is a retired SDSS image - how did you come about it?
Yes, a local cluster of stars! Sadly it is a SDSS image that has been retired - are you using the app or a normal browser?
Not a lens - too diffuse, no counter image, odd placement. More likely artifact - unable to view the raw data to check.
Only visible in the 'r band - artifact. Sorry!
A very clumpy irregular galaxy - nice!
Regions of star formation in the arms of the galaxy. Still looks quite 'young' and 'wispy' so it is not as well defined as other spirals
It has some of the visual characteristics of an AGN, but without spectra we can't confirm it. #AGNp
SDSS has it classified as a star 😄 http://skyserver.sdss.org/dr8/en/tools/explore/obj.asp?id=1237655369825845645
Faint spiral features in the galaxy, so I would go down that route 😃 Not likely to be a merger as I can't see any signs of interaction
That is the galactic core of the galaxy- sometimes referred to as the 'bulge'. The brightness of this one is causing a few artifacts!
Sadly - all photoZ 😦
Thanks - I guess. I was going to look into it after I had finished dinner. Hence the post 😃 Still a few more questions to answer...
#odd - most likely a star, will look into it later.
Lenticular is another option...
To be honest - there is so much noise in this image, there is not much that you could classify about it - apart from maybe a galaxy 😃
Looks like a spiral arm. Lensed galaxies will always have a different colour from the lens itself, the shape isn't quite right. #no_lens
You can read more in this thread 3.6 relativistic jets in optical and radio by @budgieye!
Sadly not - at the distances we are viewing it is not possible to see relativistic jets - even with the hubble telescope!
Answered on the right...
Cheers Marjie! I had a feeling you felt the same way 😃 I will look into it 😃
Hey Marjie - do you have the link? I know NED can be wrong at times, but this is certainly not a gravitational lens!
Hi everyone 😃 Please remember to only classify the object directly at the center! Not the galaxy to the top left! Thanks 😃
I would go for a clumpy irregular - difficult too tell if it is multiple galaxies. If we knew the redshift we could tell if they are related
Why do you think these are AGN's? Is it just the colour? Or do you have supporting spectra? Just curious and too busy to check 😃
I'm sorry - there is no star in this image! What object were you referring to? At the center we have a smooth / elliptical galaxy 😃
#clumpy
Hi @stuartthomas - do you have a link to the spectra that confirms this as an AGN? There doesn't seem to be anything on NED - thanks! 😃
The green and blue 'confetti'? Those are optical artifacts, they are not real - just caused by imaging and processing.
2/2 at the lower right might be unconnected. Still - there is enough to make it worth another look - Nice! 😃
1/2 The colour looks good for a gravitational #lens - but I am a bit worried about the alignment around the galaxy. Also, the blue blob ...
...and at this resolution we can only make guesses 😃
I would of classified it as such 😃 The colour contrast between the ring and central galaxy is interesting... will look into it a bit more.
wow - #stunning 😃
I am bit undecided about this one - it looks like a merger in the colour image, but have you had a look at the 'i filter on examine ? hmmm
...We can just identify star nurseries 😃 Happy hunting!
@isak.austin - in these images we are unable to see individual stars in galaxies, so we are not able to classify them into categories 😃
The blue streak is another galaxy 😃 No lensing - look for blue / red arcs around a galaxy for lensed galaxies. Hope this helps!
Blueish smudge 2 to 3 - noise or #lens ? No visible counter image, not convinced about by the shape, but it still caught my attention.
#smooth z~0.6
#merger - lovely tidal tail extending between the two!
The central galaxy is not showing any signs of disturbance, difficult to tell... sorry!
A foreground star 😃 The weird colours / shapes are artifacts caused by the light of the star overwhelming the CCD camera on the telescope.
I am also not seeing any signs of merging 😃 lovely dustlane!
Difficult to tell - it could be either. Looking at the shape I would more likely say star, but ultra compact galaxies are similar in shape.
The galaxy looks pretty symmetrical, so I don't think it is interacting. It could just be the inclination that we are viewing it.
The answer must be in one of the papers it is referenced in, but someone will have to have the time to go through them 😃
No, if you read all the comments below this object has been written up in several papers - either a Lyman Break galaxy or a star 😃
3/3 see a zoomed out image to confirm if that is the case! At the moment it is all just guess work 😃
2/3 causing the disturbance is off screen to the right. There does seem to be a faint tidal tail in that direction. We would need to ...
1/3 The bright white bit, is the bar of the disturbed spiral. The orange galaxies are unrelated to the central one. I think the culprit...
😃
Yes - they are all foreground stars 😃
A galaxy 😃 I would select 'Feature or Disk' - 'Clumpy' and take it from there...
I would go for galaxy with spiral features, not so sure about clumpy! There is no wrong answer, so just give it your best shot 😃
Foreground star for me 😃
Most of the redshifts are Photometic - in other words- an estimate. Take all the redshifts with a pinch of salt, and just classify the shape
Having said that colour is subjective - it can change depending on processing of the images and the equipment used.
.. I am sure someone could work it out - I am just at work 😃
The Voorwerp was green in the hubble images with z~0.05 - most of images we are looking at are a lot more distant, so greater redshift...
@budgie another concern it that the 'cusp' does not seem to centered around the point of greatest mass. Hmmmm...
The four upper dots would make up a nice cusp arrangement - but as you said there are similar dots in the image...
or quite possibly a diffraction spike from a foreground star 😃
It is 😃 That is why I love science! Something new everyday! I will try to read the other papers...
Which I have not had time to read - so I do not know what the final consensus was 😃
Yes, @C_cld mentioned it in his original post. The paper is quite old 2007 - I did read it earlier. Another 3 more recent references 😃
This is a foreground star - they look a bit odd in the Hubble images!
#smooth
#irregular
#stunning
When you see a (?) or PHOTO after the redshift value in NED it means it is an estimate 😃 Hope this helps! 😃
I would take the redshift on NED with a pinch of salt - the link posted below has it estimated at 2.59 - looks like both are estimates 😃
Looks like it extends through the whole image, my guess would be a removed artifact. These images are highly processed.
Could be an #overlap - not a lot of disturbance between the galaxies.
#clumpy #irregular
There is no lensing in this image - sorry.
#no_lens
Nice colour, but - the arc follows the pattern of a spiral arm. Most likely to be star formation in a arm.
Hmmmm - more likely to be spiral arms. Nice colour and placement, but I think unlikely.
Yes 😃
Cool indeed 😃 Star with background galaxy - one for the art thread 😃
wow - we are truly privileged to see these images 😃
The green blobs look like foreground stars- the colours are a bit different with this survey 😃
Sadly, the object at the the center (which we have to classify) is indeed an artifact. Otherwise I would say galaxy cluster - Nice!
Correct! Artifact on the left of the galaxy 😃
Not so much unusual, rather uncommon:-) A spiral galaxy with multiple undefined arms, that have active star formation regions.
We do! clumpy indeed!
AGN = Active Galaxy Nucleus 😃
A foreground star 😃
2/2 most likely star formation in a spiral arm 😃 The more interesting would be what caused it on one side only 😃
1/2 I think I would of gone with asymmetrical - the two sides of the galaxy do not mimic / weigh each other out 😃 As for the clumps...
SDSS = Sloan Digital Sky Survey - we were classifying that survey up until yesterday 😃 Now we are onto Hubble!
Star formation is my guess - also the galaxy is quite clumpy, so that is another clue.
Diffraction spikes from bright stars off screen 😃
Thought I recognised this one! Discussion on the right 😃
I think the blue objects to the right are foreground stars - remember to only classify the object at the center!
Another difficult one! New surveys are a learning curve for everyone 😃 I would most likely go with irregular other than merger, but... 😃
Good call! 😃
On the left? Yes,a foreground star 😃 Smooth,round galaxy at the center 😃
Wow - difficult to tell! I would most likely also classify it as a merger - but it certainly is clumpy! Irregular is another possibility..
Just star formation - but actually quite interesting...
I would go for 2 😃
That was from @kwillet - the data on NED is not infallible, always use good judgement, and trust your eyes!.
No dust lanes! I would go for spiral with star formation in the arms, more pronounced in the lower half.
"It could be simply trying to fit a photometric redshift to individual clumps in the galaxy and coming up with very different answers"
A new survey. We have blogged and posted about it. Read this
😃 I also saw that the z associated with this galaxy fluctuates from 0.70 to 3.95 in NED - will post when I get a reply!
Sorry - I was responding to another volunteer. The galaxy is interacting with the other galaxy - Nice dustlane!
2/2 ..as this survey is new for all of us, I decided to get a second opinion from @kwillet and 1.12 looks about right 😃
1/2 Oh, you got it from NED! Always map the redshift value to the first match from the table - in this case z=1.12...
I am just having a closer look 😃 My 'hmmmms' means I am thinking and looking!
As for this object...hmmmm...
Most galaxies do have black holes at the center, but we would only see this in the form of AGN's (Active Galaxy Nuclei)
I have answered you in your discussion 😃 Hope it helps!
The blue spots are regions of star formation. In these images the young stars are hot and blue in colour - nothing to do with the lifespan!
You should put that in the art thread 😃
http://talk.galaxyzoo.org/#/boards/BGZ0000002/discussions/DGZ0000vlc
Hi @turelli - where did you find the redshift value? It seems a bit high...
I can't see any dust lanes but it does look very disturbed!
All foreground stars from our own galaxy 😃
It is blue because of all the active star formation - young stars are hot and blue 😃
Not lensing, as it is the same colour as the galaxy 😃
#merger #dustlane
Maybe 😃 It could also be star formation on a spiral arm. Just go with your best guess 😃
Yes - we now now classifying Hubble images 😃
Answer below 😃 It is a satellite trail.
It is right on the edge of a field - http://skyserver.sdss.org/dr8/en/tools/chart/chart.asp?ra=180.37363329&dec=69.3240816
Stunning #merger!
It is a galaxy - I would go with a seriously disturbed spiral. The blueish region at the bottom is star formation. Happy Hunting!
😃
No ring here - this is a single, very disturbed galaxy, with some star formation 😃
An optical artifact caused oversaturation - click on link for more info!
Not colliding 😃 An optical illusion called 'line of sight' makes them look closer to each other than what they are.
😃 The evening observing run was just beginning, hence the light green back ground, the sky was too light!
More often than we would like 😦
Not a merger! The 2 galaxies are at very different distances, so it is by line of sight that they look like they are connected 😃
Nothing 😃 It is from the edge of the survey - classify as a star / #artifact and it will be removed from the classification dataset 😃
There are so many foreground stars in the image, I am more likely to think it is another star. 😃
Looking on NED it is classided as both an irregular and a close compact group - several notes and references 😃
I am sorry, I do not see any spectra associated with this galaxy. Have a read of this post for more info 😃
Definitely a galaxy!
They are certainly not galaxies! I am more inclined to go with foreground stars - but they do have a rather uncanny alignment.
Just classify as a star / #artifact and it will eventually be removed from the dataset. Thanks!
Not a artifact 😃 visible in several filters. I would say they are gravitationally bound galaxies, quite possibly interacting.
At the center or top right?
Hi @tonyg123 😃 It is an artifact - oversaturation - Happy hunting 😃
This is a foreground stars from our own galaxy - click on the link for more info 😃
Here is the zoomed out image - definitely a star: http://skyserver.sdss.org/dr8/en/tools/chart/chart.asp?ra=348.78119554&dec=72.03236077
I would go with star 😃
These are all foreground stars from our own galaxy- read the link for more info 😃
Sometimes it is difficult to tell, but I would classify this one as a galaxy, it is too diffuse to be a star. NED and SIMBAD agree - galaxy.
There certainly seems to have a very slight spiral pattern. I would also add that it looks like a low surface brightness (LSB) galaxy.
The blue lights are regions of intense star formation - nice!
Hi and welcome @Gtar 😃 are you referring to the other round objects in the image? They are all foreground stars from our own galaxy.
The object at the center is a galaxy - I would go with a LSB (low surface brightness) or dwarf galaxy.
Elliptical galaxies do not have bars, they are featureless 😃 lenticular or disk galaxy for me
I would say yes - very fuzzy and faint but certainly visible. Clearer in the inverted image.
You can read more info why here - there are also links to the original thread in the forum 😃
#dwarf #irregular
#IC 0043
#bar #spiral
I would go with a barred two arm spiral - The arms are very faint.
I would suggest blocking his email address - there is no point having to put up with all that agro 😃
Not too mention the abuse and harassment he caused / is causing.
Sorry you mistook my post for anything other than what it was 😃
Foreground stars 😃
No, it is not an irregular galaxy 😃 I would go with #dwarf or #LSB
These are foreground stars - they look odd because of imaging errors. Read this thread here for more info 😃
No star deaths are involved with galaxy mergers - Galaxies are mostly open space so all systems re-align themselves. Green dot = artifact
The lovely colours are artifacts caused by imaging errors - these objects are most likely foreground stars. 😃
A group or cluster of galaxies that are gravitationally bound -some interaction.
Foreground star - no gravitational lensing- Sorry!
#round_bulge
Galaxy - yes! The odd colouring is an artifact - these images are compressed. Looks better on the SkyServer image!
An overlap - the galaxies are not connected - they are at different distances from us.
A foreground star 😃
Click here - The image is slightly rotated.
Always remember to only classify the object at the center! The other object will get it's own chance to be classified 😃
That is an optical artifact caused by slightly misaligned filters - you can see a similar red dot in all the objects in the image. 😃
3/3 a blue colour are young galaxies with star formation. These galaxies tend to be close to us. Search 'look back time' for more info.
I would also tag it with #LSB (LSB = Low Surface Brightness) and #dwarf 😃
2/3 the distance of the galaxies from us. The blue colour galaxy is a lot closer to us than the central elliptical galaxy. Galaxies with...
1/3 Actually, the blue irregular on the left is not connected with the central galaxy 😃 Looking at the PhotoZ of both we can estimate...
Starformation can also be a normal part of galaxy evolution, totally unconnected with interacting / merging galaxies 😃
I would go with star formation, the pattern clearly follow the pattern of the spiral arms 😃
Not at lot of disturbance, so I am more likely to go with overlap,although it is really difficult to tell with some images 😃
More info on artifacts here
This is a foreground star from our own galaxy - overexposed with filter error. Classify as a star / #artifact 😃
These are all foreground stars from our own galaxy - more info here 😃
It is a foreground star from our own galaxy. Overexposed, with filter and imaging errors. Classify as a star / #artifact 😃
#x-shaped bulge
#AGNp
Only classify the object at the center - all other objects can be ignored. If I classified this image, I would go with star / artifact 😃
All explained in this thead here. A trial, at the moment it will not be expanded to other hashtags.
There is a lot of background noise in this image, have you tried viewing it in the inverse?
No gravitational lensing. A smooth galaxy at the center, surrounded by foreground stars. The green colour is down to filter issues.
I would go with #irregular galaxy 😃 Nice one!
There is no such thing as a incorrect classification, multiple people will classify the image and we go with the mass consensus 😃
Are you talking about the two bright purple objects in the bottom right? Or the purple in the galaxy itself? 😃
And what a stunning one it is! #zgotw
So it is! Classify as a star or #artifact and move on to the next image and thanks for your classifications 😃
Sorry but no gravitational lensing! These are all foreground stars. Happy hunting!
Correct! A foreground star
The colour distortion is not real - these images are made up of multiple different coloured* images and sometimes they get misaligned 😃
The blue area in the galaxy? That is a region of intense star formation. Nice! 😃
I can not see any distortions, so I would be unlikely classify it as a merger myself. Happt hunting!
Not a star! A round elliptical galaxy 😃 Sometimes it is difficult to tell them apart 😃
A foreground star from out own galaxy.Click on the link for more information!
Classify as a star or #artifact - observing / imaging / focusing errors. Most likely foreground stars 😃
The black arc? that looks like an artifact for me. Dust lanes are mostly found in disk or spiral galaxies. This is a lovely elliptical 😃
Hi Rachel, only ever classify the image directly at the center. In this case I am more likely to go with foreground star.
More foreground stars - the lack of focus and strange colours are caused by bad imagining conditions
A foreground star from our own galaxy. The colour is not real, it is what we refer to as a artifact.
They are both stars - classify as a star / #artifact and move onto the next one! Seemy other reply for a link to more info 😃
Both foreground stars - so no merging 😃 The apparent closeness could just be an illusion - line of sight.
A galaxy - the blue clumps are active star formation regions. I would personally go for 'spiral or other features' but it is your choice!
Both the object look like foreground stars - the image is quite out of focus.
No, not a merger 😃 The object in the lower right is a foreground star that is in front of a more distant galaxy.
That so cute 😃 A smiley face 😃
Hmmm, foreground stars for me - so star/artifact would be a good call 😃
An image from the edge of the survey area - Loads of filter / environmental / imaging errors. Classify as star/artifact 😃 Happy Hunting!
Hi and welcome @wtyler - This is a foreground star from our galaxy. The colours are not real - they are artifacts caused by over-saturation.
3/3 ... and you have already created a discussion about it (where you can discuss anything) , so what is the problem? 😃
2/3 Like linking comments directly to a image. We have always maintained that all comments in this section should be related to the image.
1/3 This is not the forum 😃 Talk is the Zooniverses own software, so we can do a lot that could not be done previously...
The comments have always been reserved for the image above. Two years ago there were no moderators on GZ talk, as hardly anyone used it!
The green spot is an artifact - most likely a particle strike.Only visible in the 'r band. They can be easily confused with supernovae!
2/2 The comments below should only be in reference to the image above and not objects out of the field of view. Thanks!
1/2 Hi @AlphaAurigae - unless the object is visible in the image above, can you please refrain from posing a comment about it? 😃
I would classify it as an artifact - it could be a star or a galaxy, but we cannot tell due to the imaging / filter problems. #artifact
The colours are not real - this is a image of a foreground star with loads of filter / imaging errors.
Looks like the filters were slightly misaligned, not redshifted - sorry!
Artifacts of foreground stars - classify as a star / #artifact.
As mentioned in another comment, only classify the object directly at the center 😃
You could classify it as : smooth, round, something odd, other 😃
Always classify the object directly at the center, ignore all other objects. This is an amazing galactic cluster made of dozens of galaxies.
Yes, it is a star 😃 Just classify as a star / #artifact and move onto the next image.
Only visible in the 'r filter so it is most likely an artifact that has not been cleaned up from the image.
#x-shaped #dustlane
Very faint spiral arms and features for me, not so sure about it being disturbed but with images like these it is difficult to say 😃
You could classify it as either a smooth cigar shape galaxy or edge on galaxy. It is your opinion we want after all! Happy Hunting 😃
That is an artifact of a foreground star caused by imaging errors. Classify as a star / #artifact and move onto the next image 😃
Overlap for me - no distortions, sadly, also no spectra.
These are all artifacts of foreground stars. Classify as star / #artifact and move on to the next one 😃
Not a nebula 😃 This is a young star forming galaxy, somewhat irregular in shape.
The object at the center is a star. The galaxy that SkyServer is referencing, is the one to the right. Always recheck the SkyServer results.
I would also say so 😃 Nice!
Read below 😃 Foreground stars from our own galaxy - the milky way.
Only ever classify the one at the center! And, you are right it is a spiral or disk galaxy 😃
The object to the lower left is a foreground star, so no merging n this case!
http://skyserver.sdss.org/dr8/en/tools/chart/chart.asp?ra=78.16399977&dec=27.29404528
The colour is misleading, it looks like they had filter issue when it was imaged. See the link to the zoomed out image in next post 😃
I would go for a disk galaxy - possibly edge-on.
I would be more inclined to go with an irregular galaxy. Very disturbed!
Not an AGN, no spectra. Most likely just a bright core.
Not a lot of disturbance in either galaxy- With no spectra, I am going to say that they are unrelated to each other.
These are all foreground stars from our own galaxy. Have a read of this thread here for more info 😃
I'm sorry, but I am not seeing any spectra that would suggest this is an AGN. Do you have a link? 😃
Hi Ian, no lens. The objects on either side of the galaxy are foreground stars.
Welcome to the zoo! I would go with disk galaxy with a bar.
Sorry 😦 I now have to get back to studying, so I will be scarce for the next few weeks...
The point of GZ is not about making personal discoveries, but rather contributing to the group collective.
To echo C_cld - the further investigation of objects posted on talk is mainly for our own education and to involve a wider community 😃
It is an Artifact 😃
It is an artifact - oversaturation
It is a foreground star from our own galaxy - click on the link for more info 😃
No sign of a voorwerpje - they tend to have a very distinct colouring. Most likely foreground star or satellite galaxy.
#irregular
Blue dot in the lower left of the galaxy is the target. Interesting...
I would go with a chance alignment 😃
2/2 ..interested in how you view / classify the object. Any info you post from external sources is more for educational purposes.
1/2 If it is on NED or SIMBAD, we can already cross reference it, and it would be quicker to directly query that database. We are more...
#artifact
Yes, it is an artifact 😃 Looks like foreground stars.
Very Pretty 😃
Looks like a possible AGN #AGNp
Hi Ian, nice #bulgeless edge-on galaxy - nice find! 😃
Oh, you mean the partially removed trail on the right?
2/2 is slightly to the lower right of the center. Classify as star / artifact.
1/2 Remember to only classify the object directly at the center! In this case it is a foreground star. The only galaxy in this image is...
These are all foreground stars from our own galaxy. Click on link for more info 😃
Hi and welcome @melikamp 😃 I am not seeing any satellites in this image. Happy Hunting!
Not a satellite trail 😃 A diffraction spike from a bright star off screen to the upper right.
Still an #overlap. You can see faint dustanes of the disk galaxy crossing the edgeon galaxy just north and south of the core - Nice!
An artifact caused by oversaturation
I also see a slight hint of a dustlane. Nice!
Yes, it is a galaxy 😃 I would go with disk / spiral galaxy with a ring. Looks like a possible a pseudo-ring.
You can use lower case to enter hash tags 😃 We tend to only use upper case for acronyms e.g. AGN or LSB 😃
Please read the comments left by myself and the other moderators WRT your other images classified as voorwerpjes. Thanks! 😃
No, just no.
Look at the other objects in the image - clearly the filters were misaligned.
This image has been looked at by several scientists - the pattern is just a happy coincidence!
I would go with foreground stars 😃
Looking at the SkyServer image it look more like a spiral arm. The colour is also too similar to the lens galaxy. No lens for me 😃
Perhaps Satellite Galaxy of the larger central galaxy, but without knowing the distance of both we can't tell
These are all foreground stars. The coloring and strange shapes is down to optical artifacts.
Looking at this galaxy it look a bit too light weight to have back hole. The lovely intense colouring is down to a lot of star formation.
The object below the galaxy look suspiciously like a foreground star - Skyserver agrees 😃
The QSO is way off screen to the lower left. Can we please just tag objects in the image itself? Thanks!
Why? - it is confirmed as a SN on both NED and SIMBAD. The co-ordinates match the blue spot and it is referenced in several papers.
Yes 😃 The edge-on galaxy does have a stunning dustlane.
A disk galaxy with a bar, spiral features and star formation / star bursts. Somewhat disturbed.
Have a look at the zoomed out SkyServer image - I think you might find these are all foreground stars 😃
The slightly bluer nuclei look like regions of intense star formation. Sadly, no info on NED
This is a galaxy 😃 Quite disturbed with regions of star formation. On SkyServer you can see several other galaxies close by.
These are all foreground stars - no merging going on 😃
Same as AGZ0003bzo
Same as AGZ0003bzm
No gravitational lensing - sorry! These are all foreground stars,a nice chance alignment. Happy hunting!
I would guestimate with 45 degrees off the ecliptic. Interesting green point in the close upper right of the galaxy.
The red area is an artifact -most likely a misalignment of filters. You can see a similar effect in the top left galaxy.
That is certainly an #irregular galaxy! Interesting 😃
This is a foreground star- classify as a star / #artifact and move on to the next image 😃
It is an artifact - oversaturation
More info in this thread here
Classify as a star / #artifact 😃 This is a foreground star - the weird colours are artifacts caused by imaging / filter errors 😃
No worries! It is our fault for having no hashtag guidelines!
The tags arc or lens are usually reserved for gravitational lensing 😃 Will add it to the glossary to prevent further confusion. Thanks!
A lovely galaxy with spiral features 😃 No sign of gravitational lensing - arcs will have a very different colour from the lens galaxy.
The orange object above the galactic core is a foreground star 😃
Classify as a star / #artifact - loads of imaging / filter errors.
Nice #overlap with a edge-on galaxy on the center right. As for the galaxy at the centre a disk or lenticular galaxy.
It is a galaxy - I would go with Dwarf or LSB (Low Surface Brightness) galaxy. Nice star formation regions!
#artifact
#artifact
I would go with merger 😃 Pity there is no spectra available - fascinating galactic core.
They are images from the edge of the survey area - classify as star / #artifact and they will eventually be removed from the dataset 😃
It is a foreground star 😃 not connected with the galaxy in the background. Looks like we have a #overlap at 1
This is an excellent guide on redshift colours : http://talk.galaxyzoo.org/#/boards/BGZ0000007/discussions/DGZ0000ulp?page=2
A foreground star - the colours are not real due to filter / imaging errors. Classify as star / #artifact and move onto the next one 😃
Those beams are diffractions spikes from a bright foreground star just off screen to the left 😃
I would go for a slightly denser region of star formation. Bit clearer on the SkyServer image.
Just looking at the image, I would personally go with overlap, not a lot distortion 😃
That is only for ZOAG galaxies. For the majority of galaxies it is due to the higher redshift. The further a galaxy is the redder it is.
Agree with Budgie - foreground star. Our eyes are better than an algorithm, and that is why we are classifying these images! 😃
The green dot is an artifact, most likely a particle strike that has not been removed. Only visible in the 'r filter. Nice smooth galaxy.
Nothing 😃 Just classify as a star / #artifact. This image is at the edge of the survey area so we tend to get some interesting artifacts!
A foreground star - the colours are not real due to imaging / filter errors. Classify as a star / #artifact and move onto the next one 😃
Not a nebula, possibly a satellite galaxy, but the image is really too fuzzy to tell. The orange objects are foreground stars.
For it to be considered an overlap, the galaxies need to be superimposed over each other, even if it is only slightly.
In images like this just do the best you can! Even just classifying it as a spiral or disk galaxy is a big help 😃
Only visible in the 'i filter - so it is safe to say it is an artifact.
The central objects are two interconnected galaxies - described in several papers. The blue object in the top right is a foreground star.
Where do you see the lens, so I can have a closer look? 😃
Wrong colour for a voorwerpje -It looks like the red and green filters are slightly misaligned. Spectra classes it as an AGN.
😃 These are foreground stars, so they only look connected due to line of sight. Happy hunting!
Not a voorwerpje 😃 The blue area is a region of star formation. Low Surface Brighness or Dwarf galaxy. #lsb #dwarf
To the right of the galaxy? Yes, I would go for star. Remember to only classify the central object!
That is a stunning one! Stunning #bar and #ring. #ZGOTW for me!
Spiral arms folding back on themselves giving the appearance of a ring 😃
A nice cluster of galaxies 😃 Sorry, no gravitational lensing for me.
Foreground stars from our own galaxy 😃
I think @wtaskew means is that he got this image to classify 2 years ago.... 😉
Imaging and filter artifacts - these are all foreground stars. Classify as star / #artifact and they will be eventually retired 😃
Sorry - no voorwerpje, star formation. Voorwerpjes have a very distinct colouring in the SDSS images.
Here you go: http://www.galaxyzooforum.org/index.php?topic=10635.0
It looks like a pseudoring galaxy for me 😃 I will see if I can find the link to the old thread on the forum.
The smudge down in the 7 position from the galaxy? I would go with overlap-not enough curvature forme 😃
foreground stars 😃 The colour and fuzzyness is down too imaging errors.
The red dot? I think it is a local star, but there is a lot of background noise in the image.
The red stars are part of our galaxy - the blue is more difficult, most likely star formation in the more distant galaxy.
Between what? 😃
Foreground star for me.
Edge-on galaxy with a fore ground star in the lower right 😃
No merging for me 😃 Nice overlap!
Most certainly a merger! Nice 😃
Just got this one - I agree - the 'asteroid' is odd. There does seem to be a subtle change of direction? Hopefully @c_cld will have a look
I would not tag it as boxy as it has no bulge! We use the boxy hashtag to describe the shape of the bulge 😃
It is an image close to the edge of the survey area - classify as a star / #artifact and move onto the next one 😃
More help can also be found in this thread here and here - happy hunting!
It is a local star - read the comments below 😃
Not a merger - I am more inclined to go with a #barred lenticular / Disk galaxy 😃
It does not have the distinct colouring of a voorwerpje, too similar to the colour of the galaxy. I would go with satellite galaxy 😃
right close to the galaxy core? or about a quarter way up the image? or at the edge of the image? 😃
I am really not seeing any voorwerpjies? Where exactly are you seeing them, so I can have a closer look? 😃
Looks like a LSB (Low Surface Brightness) galaxy - nice find! 😃
Really difficult to tell, could also be a dust lane in a lenticular (or disk) galaxy. Have a look at Skyserver image - galaxy cluster 😃
2/2 Having said that it is interesting enough for me to add to the #lens collection 😃 Nice one!
1/2 I was initially going with ring, but it does have nice colouring - an orange smooth galaxy and a blue ring. Wish the image was clearer!
2/2 but that do not have any supporting evidence such as spectra. The p stand for possible, this way we can keep the categories separate.
1/2 It was not tagged as an AGN 😃 It was tagged as an AGNp. We have introduced a new tag for objects that users think might be an AGN...
@Sundog1a - why don't you have a read of the this AGN for beginners, it is part of th user guides 😃
What objects are you referring too? I am seeing no signs of any voorwepjes! Sorry 😃
#lens
No gravitational lensing - we have spiral features and regions of intense starformation.
#no_lens
No,not a lens 😃 Both the objects are edge-on galaxies. Stunning accidental alignment.
#no_lens
Has a nice #bar as well!
Looking at the SkyServer image I would personally go with foreground stars - not galaxies 😃
I would go with spiral galaxy - difficult to tell if it is barred from this angel. Also seem to see some dust. Good to see you Marjie 😃
Foreground stars! If you look at the widescreen image you can see we are in the middle of a star field 😃
The two galaxies are certainly interacting with each other 😃 Nice!
The difference in colour is due to two of the filters being slightly misaligned. More info on artifacts here
Not a voorwerpje - slightly misstacked filters are causing the difference in colour between the two sides of the galaxy.
That is a stunning one! and welcome to the zoo @nhanimator 😃
star formation in an irregular galaxy, no signs of a voorwerpje - sorry!
Just classify as a star / #artifact and they will eventually get removed from the dataset.
?
#no_lens - star formation.
I think the galaxy at the center is much more distant than the other two, so no interaction / merging for me 😃
Where? No signs for me 😃 Perhaps you should clarify you posts more in future ? 😃
They are foreground stars. The overall green colour is down to filter / imaging errors.
It is just really confusing to classifiers to have images from different surveys (and wavelengths) all posted together!
AA - we have not classified UKIDSS images for a year and we have new images coming up, so perhaps we should concentrate on them? 😃
Spiral galaxy - certainly not a lenticular! 😃
An artifact caused by oversaturation - look on the right for more info. Happy Hunting!
Top right? A foreground star 😃
me too 😃
No, not an irregular 😃 Irregular galaxies are blue and well, irregular! This looks like disk galaxy, almost edge on.
Where?
Not likely- sorry 😃 Just a lot of artifacts.
No overlapping 😃 I would go for a barred ring galaxy. Nice 😃
No gravitational lensing 😃 Just spiral arms that have formed a ring 😃
A star from our galaxy. The colour is an artifact from filter / processing errors. Classify as a star / artifact 😃
2/2 enough to be an irregular 😃 I would go with a multi-armed spiral viewed at a somewhat odd angle 😃
1/2 Hi and welcome @spceodity 😃 Excellent guess - this spiral does have more star formation than normal, but it is not irregular...
I would go with star 😃 Looking at SkyServer it appears to be in the middle of a star field!
They are all foreground stars - the algorithm that chooses the objects for us to classify, though it was a galaxy 😃
Pas une galaxie, les étoiles de premier plan - aucune fusion passe. *google translate at work
The galaxies on the left are certainly merging! Not so sure about the galaxy at the center, no major distortions.
I would go with a barred spiral galaxy. The blue colour is due to star formation:-) Could also be called a proto-spiral.
Yes 😃
North of the galaxy? Voorwerps have a very vivid colour - I would go with satellite galaxy 😃
Looking at the zoomed out image I would agree - all the objects are out of focus, and it looks like a dense star field.
The bright object on the left is a foreground star, and the central object (that you should classify!) is a galaxy 😃
@liometopum - don't forgot the photoZ is just an estimate and it is advised that you take the error margins into account.
No gravitational lensing 😃 Looks like 2 galaxies merging - Nice!
2/2 triggered by interaction. Have a look here
1/2 Certainly a merger between 2 galaxies - the 2nd galaxy is off screen to the bottom. The blue bits are regions of star formation...
Dense star formation close to the core of the galaxy, if you look at it in the different filter it is not a prefect ring, spiral features?
These are all foreground stars - the odd colours / shape are all artifacts caused by filter / imaging errors.
It is all in the #how_to threads 😃
AGNp - stands for a possible AGN, that does not have any supporting spectra, therefore it cannot be tagged as an AGN 😃
Looking at the colour, this is a young galaxy - old galaxies have a red colour due to a lack of star formation.
I am not seeing any signs of lensing - what object are you referring to?
possibly this mission XMM? Not much info on NED and this is the first time I have come across it.
I am sorry 😃 but I do not see any signs of a nebula in this image. What object are you referring to?
Not an AGN - no spectra and the object to the right is a foreground star, no no overlap either 😃
We use the term overlap to refer to galaxy / galaxy overlaps - not stars 😃
I would go with smooth - round 😃
No merging for me! #overlap
Not an irregular galaxy 😃 Nice ring and bar.
Not an irregular galaxy - I would go with proto spiral. Nice star formation.
Not an AGN - no spectra, slight misalignment of filters, that is causing all to objects to have a red orb on the right.
No nebulas - the discolouration is most likely due to star formation in the spiral arms.
or you could just call it miss-aligned filters 😃
Is it just me or could this also be an overlap? Nice irregular in the front and perhaps a smaller loose spiral behind?
Not magic - an amazing barred 2 armed spiral 😃
Not magic 😃 Just bad filters. All the objects are foreground stars.
A image from the edge of the survey area 😃 Classify as a star / #artifact and move on to the next one:-)
😃
All the objects in this image are foreground stars 😃
Pleasure 😃
A foreground star
1' below the bright one
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=18.32208446&dec=23.26652521
3/3 Because they are in different fields we can have artifacts that would only be visible to images within this field. Hope this helps!
No, supernovas have a very distinct colour and are very well defined. This would be a foreground star from our own galaxy. Happy Hunting 😃
2/3 but fainter artifact just below this one. Both spatially relate to 2 stars that happen to be imaged in a different field on the left.
1/3 I think they are in fact diffraction spikes from a star off screen to the left. If you look at the widescreen image there is a similar..
Please don't call it SS 😃 It is SkyServer 😃 I will have a look...
Classify as a star / #artifact and move onto the next image. This is an image from the edge of the survey area - an artifact 😃
That is an artifact caused by oversaturation 😃 Happy hunting!
Classify as a star / #artifact and move onto the next image:-)
Yes!
@Els Jinx 😃
I wish - then I would be very rich! Image at the edge of the survey area, classify as star / #artifact 😃
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=350.42525107&dec=72.19054105
Problems with the green filter - see the zoomed out image from skyserver, all the objects in the field has the same hue. Link in next post.
These are actually all foreground stars 😃 The colours are artifacts. Classify as star / #artifact
nice #bar
Close! This is a satellite trail - more info in the Artifact thread here
These are all foreground stars, looks like we are in the middle of a star cluster! 😃
Looking at the SkyServer widescreen image there are several similar objects close by, also nothing on NED, both things suggest star.
These are all foreground stars - the weird colours are down to filter / imaging errors. Classify as star / #artifact 😃
I am thinking perhaps it was an artifact that was removed during processing - it extends through the whole image (square root on examine)
Not so sure it is a merger - on first glance I would of gone for overlap 😃
Why? No spectra and it does not look like a particulary promising candidate?
Just classify them as a star / #artifact and move onto the next image. 😃 They will eventually be removed from the dataset.
#abell 0313 galaxy cluster
Hi @julieharkin 😃 That is a diffraction spike from a really bright local star just off screen 😃
It is a satellite trail 😃
This is an image from the edge of the survey are, just classify as star / #artifact and move on to the next image 😃
I am not so sure it is merger, the object on the right looks suspiciously like a foreground star.
The green object is only visible in the 'r band so it is an artifact. The other object is a foreground star.
No spectra - so it is not possible to confirm it as having an AGN. Nice bright core though.
star / #artifact
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=6.3832813&dec=23.58738258
Galaxxies 😃 If you zoom out on SkyServer you can see it is a galaxy cluster, see link in next post,
Classify as star # artifact - loads of filter errors.
I would go with spiral galaxy myself, as a complete ring has not formed and it is slightly disturbed a the top 😃
Just give it your best shot! 😃
Not a nebula, SkyServer has it listed as a star.
No, that is not a AGN. Just a fuzzy spiral galaxy.
DMS stands for Deep Multicolor Survey. It is just another identification that can be allocacted to galaxies / QSO's.
I would say it is a galaxy - the image is just quite fuzzy.
Definatly a galaxy, but the colours do look slightly misstacked 😃
Sorry - no signs of being an AGN.
No interaction for me 😃 The orange object on the right of the galaxy is a foreground star 😃
Not an AGN - please check your PM's. Thanks 😃
Not an elliptical for me - perhaps a lenticular S0 galaxy?
The lowest object is a galaxy, the others are stars. Due to focusing/ filter errors they all have the colouration. Classify as star/artifact
This is a foreground star , not a AGN 😃
Also,it does not display any of the features we would expect to see in galaxies that harbour an AGN.
Not an AGN - no spectra 😃
No AGN, no interaction.
It is an artifact - only visible in the 'i band
http://skyservice.pha.jhu.edu/DR8/ImgCutout/getjpeg.aspx?ra=240.53659093&dec=15.88817671&scale=0.79224&width=512&height=512&opt=&query=
Definitely not a merger! #overlap for me 😃 The edge does not look connected to the awesome galaxy cluster seen in the zoomed out image.
Sometimes the algorithm that selects the images for us to classify gets confused by bright objects 😃 I agree with star...
Not an irregular galaxy - this one has spiral features, so perhaps a proto spiral?
I would go with #overlap 😃 There are no distortions in either galaxy. Looking at the color / photoZ the galaxies are far apart.
No, this is a galaxy- somewhat disturbed with spiral features. The bright blue bits are regions of dense star formation. Nice! 😃
star / #artifact 😃
All the weird colours are artifacts caused by over saturation - no solar flares - just imaging errors 😃
You don't get bars in elliptical / smooth galaxies, so this would be a lenticular or disk galaxy.
Welcome to the Zoo!😃 I would be more inclined to go with a very loose spiral with no bar - but that is just my opinion. Happy Hunting!
Are you talking about the white object below right of the galaxy? That is a foreground star - no merging 😃
Not an AGN - and no signs of interaction between the galaxies for me 😃
More likely it is just a coincidence caused by line of sight 😃
This is a smooth or elliptical galaxy - not an AGN - Sorry!
Looking at SkyServer it is an image from the edge of the survey area, so lets mark it as an #artifact 😃
It is an image from the edge of the survey area- that is why is has a green background. An artifact. Happy hunting!
2/2 I would say this galaxy has spiral features with star formation. Hope this helps! 😃
1/2 Sadly not 😃 Irregular Galaxies tend to be predominantly blue with intense star formation and a very irregular in shape.
It is still quite a interesting colour 😃
To the top right of the galaxy? More likely foreground stars - I would of expected the colour to be more vivid if it was a voorwerpje 😃
You first guess is correct! Three stars 😃
This is not an irregular galaxy - it is a spiral. Irregular galaxies are usually blue in colour with active starformation regions 😃
I have seen similar images and they turned out to be diffraction spikes. Really pretty 😃
NED is not always right 😃 I am more likely to go with an active star forming region, we seem to have a fainter area on other side of core.
A foreground star from our own galaxy. Sadly there were a lot of filter issues when this was imaged. Classify as star / artifact.
It doesn't have the colour we would expect for a SN in the SDSS images. I would wait for @c_cld to give it a look 😃
Hi 😃 Only ever classify the object directly at the center - ignore all other objects. Happy hunting!
Here you go: 3.6 relativistic jets in optical and radio by @budgieye!
Very unlikely 😃 As far as I am aware there is only 1 that we can see in the SDSS images - I will see if I can find the link to the thread!
Hi and welcome @ecary - this is a bad image from the edge of the survey area! Just classify as a star / #artifact 😃
2/2 You could also flag it as a possible merger, as the galaxies certainly appear to be interacting - but it is really your choice 😃
1/2 Remember to only classify the object directly at the center - in this case it is lower edge on galaxy with the dust lane.
Could be 😃 Difficult to tell with no redshift. They could also be galaxies that are in the same group but not interacting with each other.
Hi and welcome @TeresaFearn - it takes a while before the results get released. How did you classify it? Also - there is no wrong answer 😃
I don't think it is merger - the galaxies are not very disturbed. I would more likely say overlap 😃
2/2 left of the galaxy looks unrelated. I would of gone for features, not a spiral / edge on - but that is just my personal opinion.
1/2 This image is incredibly fuzzy so it is not proving very easy for me either. I would not go for merger as the orange object in the top
WOW 😄 That is a beauty!
Not so sure about boxy - I would of classified the bulge as round. Then again, I am not always right! Other opinions?
Hi and welcome @mika75 - that is a star from our own galaxy. It is from the edge of the survey area, so the colours are all artifacts.
and NED would be correct!
Hi @ionutab 😃 These are all foreground stars - happy hunting!
The other objects in the FOV are foreground stars, or are you talking about the smudge on the left of the galaxy?
No, not a merger 😃 These are all foreground stars
Possible polar ring for me too!
This is a foreground star from our own galaxy. The weird colour are artifcts caused by filter issues..
The blue spot is a star from our own galaxy 😃
These are stars - the weird colors are down to filter errors. More info here
I would go with artifact 😃
on the right? That is also a foreground star 😃
'viking helmet' - I like it 😃
Foreground star superimposed over a galaxy 😃 No merging here!
very odd.
With the amount of distortion in the 'arms' I would of expected a second core to be visible if it were a late stage merger.
Certainly look disturbed. The culprit is not visible in SkyServer. Hmmmmm.
Nothing wrong with pink! 😃
Nothing on NED / SIMBAD - so I will go with my initial guess - star!
Not so sure it is a merger 😃 The pink blob is most likely a foreground star, but I will have a look into it.
The orange object below the galaxy to the right? That is a foreground star 😃 Also remember to only classify the central object!
We are all rookies once 😃
Sadly not 😃 The colours in the galaxy are an artifact, perhaps the filters were slightly misstacked?
No arcing or dust lane 😃 It is just a very fuzzy spiral galaxy.
It is an artifact. Something went horrible wrong with the filters/ focusing when this image was was captured 😃
That looks like a much more distant galaxy that is being overlapped by the central galaxy.
Looking at the colour I would say they are a fair distance apart. Two separate overlapping galaxies for me.
Wow - very similar to 'The Swan' http://talk.galaxyzoo.org/#/boards/BGZ0000004/discussions/DGZ10067u9
It is an image from the edge of the survey area - the greeness is all down to filter errors 😃 Classify as star / artifact
Certainly a double! I am just wondering whether the third nuclei in the centre is in fact a star. Similar objects in FOV. No spectra 😦
Certainly a possibility, but we would need the actual redshift values for both galaxies to know for sure.
They are all foreground stars 😃 Also, remember too only to ever classify the object directly in the center! This time star / artifact
When taking the error margins into account, the PhotoZ is quite similar, I wouldn't be so quick to dismiss it as being an overlap.
The blue object? That's a foreground star 😃
Star formation at the tips of the arms 😃
I assume you are speaking of the central galaxy? Not a lens 😃 Those are the arms of a spiral galaxy.
Only visible in the 'r band / filter. So I would say yes, artifact 😃
I would go with just edge-on 😃 You would not see a bar from this angle.
Only ever classify the object directly at the center 😃 That is the rule irrespective of whether there is a star in the image 😃
😃
oversaturation
repost of hubble image: http://www.spacetelescope.org/images/heic0810ax/ (thx @klmasters)
A tidal tail - late stage merge of 2 galaxies 😃 You can find more info in the comments below 😃
Not a voorwerpje 😃 A LSB / dwarf galaxy with some starformation. The orange objects are foreground stars.
Hi @Dippo - just look for dust trails in the normal image 😃
I would say it looks like it! Nice 😃
Hi @RG85 😃 We are all new at this once! Happy hunting 😃
They are all foreground stars 😃 Have a read of this here
Another galaxy 😃 Remember to only classify the object in the center of the image!
I am going to go with #overlap for this one. Can't see much disturbance. Sadly no spectra. PhotoZ error margins quite high.
#no_lens
Every image gets seen and classified by multiple users 😃
Only ever classify the central object - in this case it is a foreground star 😃 Happy hunting!
Another galaxy:-) There is not much more info available,but unlikely to be connected to the central galaxy.
Taking the rest of the image into account, I think background noise is the most likely culprit 😦
Foreground stars 😃 They look really weird due to filter / focussing problems with the telescope.
Wow! Congrats!
Hi brissels 😃 Where about do you see the satellite? The green smudge to the left of the galaxy core?
Over saturation for me 😃
That is a galaxy made up of billions of stars 😃
The orange object at the center is a galaxy, the other objects are foreground stars 😃
star / #artifact
The large blue object is a star 😃 the object at the center is in fact the orange object to the left.
Just a foreground star - the weird colour and lack of focus were caused by filter errors. More info here
That is the core of the galaxy 😃 No spectra, but wouldn't be surprised if it was a AGN.
😄
Yes 😃 The bright blue bits are areas of dense star formation. BTW welcome to GZ 😃
No spectra, but I am more inclined to say foreground star.
@nickdwyer53 have you seen my response 5 minutes ago? Classify as star/artifact and it will eventually be removed.
Not a dust lane or ring - It is a bit easier to make out the spiral arms in the inverted image. A bit disturbed.
If you classify them as a star / #artifact they will eventually be removed from the dataset.
Intermediate Galaxy Morphology
Basic galaxy morphology
Elliptical galaxies do not have bars, so this would be a lenticular or disk galaxy 😃
Although the central galaxy is part of a cluster (see Skyserver) - the edge-on looks unconnected.
I have replied to you on the right -->
I would go with #irregular galaxy with clumps of star formation 😃
This is not a merger or a lens (#no_lens) - it is just several unconnected objects that happen to share the same field of view 😃
Just classify as star / #artifact and they will eventually get removed from the dataset 😃
Hi and welcome @SarahSt - these objects are foreground stars, the weird color are down to filter errors. You will come across a lot of them!
It is a foreground star 😃 As are all the object in the FOV
Where about? On the left? 😃
hmmm, Did you just get this one to classify?
😃
I would say over saturation is more likely the culprit and not the misalignment of filters, as the galaxy looks nicely aligned 😃
It certainly has the features of a bar - nice find! #bar There also might also be a few foreground stars directly in front of the galaxy
pseudo ring?
Where about are you seeing the lens? Is it the red line on the right of the galaxy?
In this case I would say they are all foreground stars 😃
I would also classify it as a ring, not a spiral 😃 Nice one!
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=157.05002963&dec=6.29898237
That line is a diffraction spike from a bright star off screen 😃 See linkin the next comment for a zoomed out view.
Nice one! one for the #alphabet collection 😃
Read this thread here for more info on the different type of artifacts you could come across. Happy hunting!
Actually the other way around 😃 The filters have messed up the stars! It is not abnormal to have these problems on the edge of the survey.
no worries 😃
or you could just look left, and click on the 'Orion Nebula thread' 😃
It is part of a #nebula - a link to a zoomed out image is coming up 😃
I would agree, there are certainly spiral features:-)
Even if there is more than 1 galaxy in the image - only ever classify the object at the center 😃 Thanks!
This is an #artifact from the edge of the survey area 😃
I can see the core or hub of the galaxy.Perhaps it is because the arms are very loose?
Foreground stars 😃
Not an irregular galaxy 😃 as @ElisabethB said a spiral galaxy 😃
In these images voorwerpjes are usually blue or green in colour 😃 Nice merger!
#artifact
Only classify the object at the center - in this case the almost edge on galaxy. The bright object on the left is a foreground star:-)
Hey Leonie 😃 do you need any help?
Not a star - a galaxy 😃
What an interesting galaxy 😃 possible bar? http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=44.45586424&dec=-2.32850145

star / #artifact 😃
Firstly - only classify the object at the center. Ignore all the foreground stars. I would go with a smooth round galaxy 😃
a foreground star 😃 Have a read of this thread here
I do not think the red objects are interacting with the galaxy. There is a lot of background noise,but my gut instinct says stars.
Filter and focusing problems - I would say they are most likely foreground stars.
No interaction - I would say it is a chance alignment.
I would go with merger 😃 See how disturbed the spiral is?
This is a difficult one - not a edge on, no bulge, it does display some spiral features and the foreground star does not help. Hmmmmm
I will go with foreground stars 😃 Also, it looks like we had some focusing issues 😃
Star! 😃
#artifact
Yes 😃 It is an #artifact. Imaging and filter errors are to blame!
#artifact
#artifact
#artifact
A foreground star - classify as star/#artifact. More info in this thread here
They are foreground stars from our own galaxy 😃 Looks like there were focusing issues with the telescope.
Only classify the object in the center - in this case the smooth galaxy. You could flag it as being 'Odd / Merger' - but that is just me 😃
Peas tend to be very compact and dense - more so than this galaxy. There is loads of info on the Forum, you should start there 😃
SIMBAD says it is a possible AGN. I am more likely to go with that, than a pea galaxy 😃
Awesome 😃 A #satellite trail!
A nice cluster of galaxies - they look like they are gravitational bound rather than merging 😃
star formation?
These are all foreground stars 😃
Filter problems! Looks like there was an issue with the red filter. Zoomed out image here (click 'get image')
Not a nebula 😃 A galaxy with loads of star formation and very high HI emissions. Have a read of the comments below 😃 Also a #dustlane !
Only classify the object at the center. In this case a spiral galaxy with a slight bar. The orange objects are foreground stars.
Close! They are all foreground stars from our own galaxy 😃
This is a galaxy 😃 The dark spot is a artifact caused by over saturation (aka over exposure). also has hints of a bar!
It is a dwarf galaxy - the blue blobs are regions of intense star formation, otherwise known as starbursts. High HI galaxy
Hi @SeanD82 😃 Only ever classify the object directly in the center. The object on the left is a foreground star - hope this helps!
I would personally go with #merger 😃
Only in the 'r band - artifact.
Only ever classify the object at the center - in this case it is a galaxy 😃 Nice cluster - have a look on SkyServer!
They are slightly misaligned - but you should still be able to classify it 😃
I'm sorry - I do not see an asteroid in this image. As you referring to the skyserver image perhaps?
#artifact
#artifact
#artifact
Personally, I would go for galaxy. The edges are not as clearly defined as those I would expect in a star.
I think you would be right 😃
The central object is a galaxy 😃
Too blurry to tell, but satellite galaxy would be a good guess 😃
3/3 If you look at other official collections you will see other 'originators'. Same will happen if you create a hashtag collection 😃
2/3 Whenever an image gets tagged with the specific hashtag (in this case 'nebula') it gets automatically added to the collection
1/3 It is not my collection - I just created the criteria for the official GZ Nebula hash tag collection 😃 I have no collections.
#artifact

#artifact
Sorry no, once you have classified an object that's it - no going back 😃
That is still a galaxy- I can see a slight spiral pattern and areas of star formation. Fairly non-descript 😃
#artifact
I know they can be frustrating! Classify as star / #artifact and they will be eventually removed from the dataset 😃
#artifact
There is another larger galaxy to the left 😃 Click here for the zoomed out image.
It is a single galaxy - the filters are misaligned 😃 have a look here - you may have to click 'get image'.
On the left we have an #asteroid and on the right a partially removed satellite trail 😃
Classify as a star / #artifact - there were loads of filter / imaging errors when this was taken. Sorry 😃
#artifact
#artifact
#artifact
#artifact
I think I would go with #overlap for this one 😃
psuedo-ring?
It is a foreground star 😃 The weird colours are artifacts caused by focusing / imaging errors.
Wrong colour for a voorwerpje - they tend to be blue/green 😃 Looking at SkyServer I would say artifact.
If you have a look on SkyServer, it is part of a cluster - nice!
I would also go with edge-on - really bright core - possible AGN?
Yes 😃 In these images blue = star formation, and this galaxy looks like it has a lot of star formation going on.
and I prefer to use my username... just saying 😃
Ooops - a glitch in the matrix - I was actually posting to this image AGZ0003mxc
The dot at the center is an artifact-over saturation. 😃
Background noise - artifacts 😃
All foreground stars - the weird colours are imaging errors 😃 #artifact
In this case it is definitely a artifact 😃
Yes 😃 #artifact
That is a diffraction spike from a bright star off screen 😃
Classify as star / #artifact - there were filter problems when this image was taken.
Nice starformation 😃
These are all foreground stars - the weird colour are down to filter / imaging errors. Classify as a star / #artifact
#artifact
Yes 😃 that dark spot is an artifact caused by over saturation (i.e the brightness caused a problem with the ccd)
The big green object along with all the other objects are foreground stars 😃
#no_lens the discolouration is an artifact - other objects in the region have similar colour distortions 😃
They are both stars 😃
That is a tidal tail 😃 the galaxies are interacting and starting to merge - Nice!
The orange object is indeed a foreground star 😃
Sorry - No galaxies, they are all stars.
They are all foreground stars - the weird colors and shapes are down to filter and imaging errors #artifact
and a gorgeous dust lane 😃 Wish I got these ones to classify!
It is a satellite trail - awesome 😃 More info here
Looks like a bar in a disk or lenticular galaxy 😃
They are all foreground stars, the filters were misaligned when they were imaged, so they are very distorted. Classify as star/ #artifact
No lensing 😦 Just slightly misaligned filters. Have a look here for lens targets
Not an irregular galaxy - a smooth or elliptical galaxy 😃
#artifact - see budgies comment on the right.
Looks like an elliptical galaxy for me, but each to there own 😃
Problems with the green filter #aartifact
Stars from our galaxy -more info on artifacts here
Not a nebula - foreground stars with loads of imaging / filter errors 😃
The bright white objects on either side of the galaxy?
Those are actually foreground stars from our own galaxy - the weird colours are artifacts 😃 More info here
It does seem to have some spiral features - just classify it as you see it 😃 There is no wrong answer.
Your first guess was correct 😃 The other figures are stars from our own galaxy 😃
Apart from the almost edge on galaxy at the center, the other objects are foreground stars 😃
Read below - it is a star 😃 The weird colour are artifacts cuse by filter / imaging problems 😃 #artifact
#artifact
It is an image from the edge of the survey area - just classify as a star / #artifact 😃
Imaging / processing error - classify as a star / #artifact 😃 They do eventually get removed from the dataset.
#artifact
The red object is a foreground star in our own galaxy 😃
The filters were outof alignment when this object was image - just classify as star/artifact in future 😃
Difficult to say - I am not seeing a lot of interaction. My gut instinct says no.
I agree - foreground stars 😃
No lensing 😃 Starformation in a irregular galaxy.
It is a merger for me - the green dot looks more like a starburst than a nuclei, having said that there is something odd about it...
The green bits are also regions of intense star formation 😃
Not an irregular galaxy 😃 Barred two arm spiral - irregular galaxies will show no signs of having a spiral pattern.
Not a problem! It happens to all of us from time to time 😃
Not a nebula, an artifact. There is a very bright star off screen to the left.
[2/2] Also, irregular galaxies tend to be blue (due to the starformation) and are quite chaotic in appearance 😃 Hope this helps!
[1/2] Sorry - but I would not call this an irregular galaxy 😃 We can see a spiral structure, and it is fairly symmetrical.
That is a stunning one! #zgotw
I personally do not think they are interacting, so no merger fusing for me 😃
Stars have more clearly defined edges, galaxies are more diffused. The colour can also play a role in differentiating the two 😃
The green line is a satellite trail 😃 They move so fast they only get captured in a single filter. They can be green , red or blue.
#artifact
Foreground stars - the colours are artifacts caused by imaging / filter errors 😃 #artifact
So there is no confusion - lenticular galaxies can also be called disk galaxies - read this here
I personally would go with a separate arm. As for the white dot SkyServer has it tagged as a star and I agree 😃
Most likely stars from our own galaxy - filter / focusing errors 😃 #artifact
A foreground star - the weird colours and lack of focus is due to imaging errors 😃 #artifact
Yes 😃 the brightness of the foreground stars cause problems with the imaging. Have a read here
#artifact
Only visible in the 'r band - more likely to be an particle strike.
That green area is an artifact - if we look on SkyServer it is not visible. A field runs through the image. Happy hunting 😃
An #artifact - the green images are quite common at the edges of the survey area.
#artifact
#artifact
Just a average star from our galaxy 😃 Neutron stars would not be visible in these images 😉
No sign of lensing for me 😃 Nice #bar!
😃
The host galaxy looks a bit different from the image posted here
I would agree - 2 foreground stars 😃
#artifact
#artifact
#artifact
yup - #artifact
All local stars combined with filter / imaging errors. #artifact

Not a nebula - a galaxy! 😃 I would go with a barred proto spiral. The blue colour indicate a young galaxy with star formation.
It is a satellite trail that has been partially removed from the image. Hope this helps!
#artifact
That blue thing is a star from our own galaxy 😃
They are all foreground stars from our own galaxy. Focus / imaging errors. #artifact
#artifact
Not an asteroid 😃 a #satellite trail
#artifact
#artifact
Not a merger 😃 Just a complex #barred #multi arm spiral 😃
Only ever classify the object directly at the center - star / #artifact for me 😃
No lensing 😃 but you said it - three galaxies!
#zgotw
No explosions 😃 That is an out of focus star from our own galaxy. #artifact
Possible #AGN - no spectra, nothing on NED or SIMBAD.
A very bright foreground star! #artifact
I would go with a faint spiral arm 😃
star 😃 #artifact
The green speck looks like a cosmic strike - only in the 'r band.
No 😃 It looks like a single galaxy at the center with some spiral features. Or are you talking about another feature in the image?
They are all foreground stars 😃
Yes - #artifact
Not really - it is not that uncommon 😃
#zgotw
nice #bar 😃
Looking at the colours of the galaxies, the top one is a lot closer than the central galaxy. Slight #overlap
Yes, a star 😃 #artifact
A lovely elliptical galaxy 😃
I am more tempted to say #overlap - few signs of interaction in the smaller edge-on galaxy.
I don't think it is radioactive 😃 it could be 2 galaxies, another possibility is a dust lane 'separating' the galaxy.
I would say yes - it is clearer on the SkyServer image. Possible #AGN candidate
Always classify the object directly at the center, in this case it is the fainter of the two galaxies.
#artifact
#artifact foreground stars
#artifact
#artifact
Only ever classify the object directly at the center! The other galaxies will have there own chance to get classified in another image.
Most likely foreground stars that are very out of focus due to imaging errors - classify as star / #artifact
#artifact
Just a slight colour artifact - no outside influences 😃 Over-saturation due to the brightness of the galaxy.
That line is a diffraction spike from the star - an optical artifact - it is not real 😃
Unlikely 😃 The orange central object is a far distant galaxy, the bright white / green object next to it, is a star from our own galaxy.
The bright object on the far left is a foreground star from our own galaxy - no interaction 😃
No, artifacts generated by imaging errors.Classify as a star / artifact and move on to the next classification 😃 #artifact
Sadly not 😃 All foreground stars from our own galaxy. #artifact
This is a fairly young spiral galaxy so the blue bits are not gas (per se) but regions of star formation.
The foreground stars are in our own galaxy, so no merging with more distant galaxies 😃
Where about in the image? On the left edge? or within the galaxy itself?
Have a read of this thread here for more info 😃
#artifact
They are all foreground stars - there were problems with imaging when the photo was taken. Classify as a star/artifact 😃 #artifact
Foreground stars #artifact
I would say foreground star - SkyServer agrees 😃
and we have an #AGN - even better 😃
A spiral galaxy 😃 The arms have just backed onto themselves to give the appearance of a ring.Nice!
It is a smooth or elliptical galaxy 😃
I would go for merger, some interesting colour artifacts.
A merger of 2 galaxies - you can also see hints of starformation triggered by interaction. The larger orange object is a foreground star.
What a stunning spiral galaxy! Did you have a question about it @dderek? 😃
#artifact - the colours of the stars are not real, all of these images are processed to highlight galaxies.
Another option could be gravitationally bound, but for me #merger - similar photoZ and early signs of interaction.
No it is not star at the center but a AGN 😃 Nice!
Not irregular at all - a fuzzy spiral galaxy 😃 Irregular galaxies will have clumps of star formation and will be very irregular in shape.
I would say galaxies and by looking at the colour they are a lot closer than the central galaxy.
#artifact
That streak is a diffraction spike from a bright foreground star just off screen to the upper left 😃
I am more inclined to go with spiral arms or pseudo ring 😃
..another possibility is foreground star, but I am not convinced of that. I will add it to the list to be looked at by the Science Team 😃
Not likely to be an optical artifact, as it is visible in all filters. Skyserver has it listed as a galaxy - which it certainly isn't...
#artifact - All foregrounds stars - problems with the imaging caused the weird colours.
They are all foreground stars - so in future classify as star / artifact 😃 #artifact
#artifact
Classify as star / artifact and they will get removed from the dataset 😃 #artifact
The two objects are unconnected - the orange object on the left is a foreground star.
The denser object is a foreground star, so it is a lot closer than the galaxy.
If they were close enough they would eventually merge - although in this case I am not seeing many signs of interaction.
Imaging / filters errors caused the strange discolouration in this image - #artifact
Not a galaxy but a foreground star from our own galaxy - #artifact
It is a foreground star from our own galaxy - #artifact
That is most certainly a galaxy 😃
Yes, a coincidence - they are foreground stars from our own galaxy 😃
#artifact

Not a supernova - but a foreground star 😃
Sorry guys - #no-xshape - we are interested in the shape of the bulge not the nucleus.
???
If you had read our replies you would know the answer 😃
#no_xshape - only ever tag the object at the center, the other galaxy will have its own image. 😃
#no_xshape
outer edge? right as in right, or as in correct?
#x-shaped
@Mjtbarrett - awww thanks 😃 But trust me, the world is a better place without me singing 😃
Most likely foreground stars - but something went wrong with the imaging. In future just classify as a star / artifact 😃 Nice art 😃
I am neither Alpha Aurigae or cappella.
Zookeeper can confirm my identity 😃
What is your point? @ planetaryscience?
...and I don't sing....
Aaahhh, my nick. I named myself after one of my favourite stars 😃
What is pseudo?
No signs of gravitational lensing 😃 The 'arc' is a spiral arm. We love answering 😃
lol 😄
Not a ring - the spiral arms have wrapped around the galaxy creating the impression of a ring 😃 Nice galaxy!
All foreground stars - nice chance alignment 😄
#artifact

BTW - a foreground star 😃
Have a read of this thread - more information on artifacts etc...
Most likely foreground stars - we can see a lot of similar objects in the image.
They are spiral arms - have you tried using the 'invert' function? It is really helpful 😃
Yup - the well defined orange object on the left is a foreground star.
They are both foreground stars - have you read this thread yet? 😃
@ekristia - we have been answering all your questions for the past week with no reply. Please let us know you are reading our replies 😃
The 'tail' is a spiral arm. The 'blob' a foreground star. What is not clear is what caused the arm to be so disturbed.
The arms are actually quite well defined 😃 Have you tried using the 'invert' function?
They are all foreground stars - mark as star / artifact.
Not a line of stars - it is a satellite trail that has been removed from the image leaving behind a slight artifact 😃
Not a lot on NED, nothing on SIMBAD.
Looking at it some more, I do not think the objects are connected. Sadly, no spectra.
The central object is the larger bright blue blob at 12 - I do not think it is a merger. I am thinking starburst is more likely... odd.
#artifacts
#artifact
A spiral arm 😃
All artifacts 😃 Looks likes there were problems with the scope when this field was imaged- Sorry!
Have a read of this thread here- more info on the different types of artifacts you will come across
The lower object is a foreground star from our own galaxy - the bright center is an artifact caused by over saturation / exposure 😃
They are all foreground stars - looks like there were some imaging problems with the scope. Classify as star / artifact 😃
Have you read our other replies?
It looks like the different colour filters were slightly misaligned - these are artifacts. Other objects in the field have the same problem.
And you would be correct 😃
To be honest, there is really no point in tagging any of the old surveys...
Exactly that - the images were digitally altered to change the colour of the galaxy.
As they have been digitally altered they should not be added to the collections.
A galaxy - stars tend to be more cleanly defined around the edges 😃
The white object is a foreground star that is superimposed on a spiral galaxy - so no gravitational lensing 😃
It is a foreground star...
I will be honest, it is not very x-shaped - I would personally leave it out of the collection.
The red line at 10 in the galaxy? or the red dots?
No gravitational lensing - two galaxies with some colour artifacts 😃
All these objects are foreground stars from our own galaxy- So no gravitational lensing 😃
That is a foreground star 😃 Remember to only ever classify the object directly at the center - but commenting on them here is fine!
#no_comet
They have very similar redshift (0.051 and 0.052) so they are at similar distances to us. Taking into account the interaction - merger 😃
Look like a #pseudo-ring as well 😃
It is a foreground star - the weird colour are artifacts 😃
They are both foreground stars from our own galaxy. We have to look through our own galaxy to see the more distant ones 😃
Discussion updated 😃
Hi and welcome nachoir 😃 Yes, artifacts from foreground stars - looks like a problem with the green filter - Sorry, and happy hunting!
I don't think there is any typical figure as it is dependant on so many factors (gas, dust etc...) - I will see if I can find more info...
These are artifacts - looks like there were problems with imaging. More info here
I would go with 2 galaxies merging 😃 Loads of interaction.
A foreground star - have a read of this thread here for more info 😃
These are artifacts, caused by imaging errors with the scope - just classify them as star / artifact 😃
Sorry! no merging galaxies - foreground stars 😃
The bright object on the right is a foreground star from our own galaxy 😃
These are all foreground stars from our own galaxy. No signs of lensing, it is just artifacts caused by over saturation 😃
Hey @ekristra - are you reading any of our feedback? Sorry for being so abrupt - but we have replying to you all day...
Also have a read of this thread - here 😃
Hi and welcome @ekristia - these are foreground stars - have you seen the other replies we have left you? 😃
They are all foreground stars - nice chance alignment 😃

It is another galaxy so no gravitational lensing for me 😃
There is a much larger galaxy that is off screen to the top right. Have a look on Skyserver - it is quite awesome 😃
All foreground stars from our own galaxy 😃
An irregular galaxy with loads of star formation 😃
Nope - diffraction spike 😃
You may need to click on 'get image' on the left 😃
Not broken - just cropped. Full image here
Not disturbed 😃 A normal looking 2-armed spiral galaxy - very fuzzy, but still normal 😃
I am also thinking #overlap 😃
Actually this galaxy is fairly undisturbed! We only use the term 'disturbed' if the galaxy is asymmetric 😃
Galaxy with spiral features- pseudo ring perhaps?
They are all foreground stars 😃 This thread here has more info 😃
Always classify the object at the center - in this case the edge-on spiral galaxy. Merger with possible collisional ring on the left 😃
It is a galaxy - it is a overlap 😃 The two galaxies are not interacting.
#no_nebula
A elliptical or smooth galaxy - galaxies tend to have more fuzzy edges, unlike stars 😃
It is a spiral 😃 You can see the arms protruding from it, if it was less fuzzy, it could be a gorgeous one 😃
A satellite trail 😃 They move so fast they only get captured in a single filter 😃
#no_nebula
😄
I can do three if you want? Just more work!
Dark nebula.
Do you think we need separate collections for all types of nebulas? I was hoping we could get away with one instead of 3?
Very #disturbed, I would say the orange objects (amongst others) are foreground stars. Clumps of #star-formation.
Finally got this one to classify 😃 Nice 😄
As pointed out below - an irregular galaxy with starbursts 😃
I would say no, more inclined to go with a S0 lenticular galaxy 😃
Artifacts 😃 Looks like the whole field was out of focus.
I would say so 😃 Several arms are clearly visible 😃
...lower right looks a lot closer. A difficult one. I will add it to the collections so we can have a closer look. #lens
It looks interesting, but just the difference in colour between the arc and counter image discounts lensing. Top left more distant galaxy...
Interesting spectra associated with this galaxy, high OIII and Ha emissions... Starburst at lower 6?
The 'pearls' are all foreground stars from our own galaxy - hope this helps! 😃
No, but its fine! A set number of volunteers will also classify thisimage, so mistakes iron them selves out. We are all new at this once 😃
Welcome 😃 They are artifacts caused by imaging errors with the telescope. From the looks of it I would say stars.
Yes 😃 They are all foreground stars.
Thank you for being a part of it 😄
It has already been looked at by several Scientists, so if they had found it interesting it would already be on a list 😃
#no_lens
Classify it as a star / artifact 😃
It means that there is no signs of gravitational lensing 😃 Just cleaning up the collection 😃
IRAS F21274-0301 aka Abell76 - #collisional-ring [5] galaxy.
Interesting... it has turned up in a paper about collisional rings. Will need to read a bit more... Read Here
It is a galaxy - originally misclassified as a Planetary Nebula - 2 notes in NED, and loads of references 😃

Alignment is also a bit odd.
Slight discolouration in lower right of galaxy at 4. Bit diffused to be a #lens, but will have a closer look. Most likely star formation.
#MCG No spectra, but we have a stunningly bright core.
An #irregular galaxy with #star-formation 😃
No galaxies involved - read below 😃

A bit too far from the 'lensing galaxies' to be a lens, also the alignment is wrong 😃

#no_lens - the 'lens' and 'lensing galaxy' are all part of the same group. The 'lens' will always have a different colour to the galaxy.
#no_lens - spiral galaxy 😃
#no_lens - looks like a ring. Also lenses will be quite different in colour to the lensing galaxy.

2/2 ...single image we would never be able to tell 😃
1/2 The surveys we are looking are aimed towards looking at distant galaxies not stars within our own galaxy, just by looking at this ...
Widescreen here
Click here for the widescreen view
We have a nebula in our midst 😄
2/2 and a yellow foreground star in the lower left 😃
1/2 Not a overlap 😃 We only use that term when two galaxies are overlapping. In this case we have a galaxy with star formation...
Certainly not a irregular galaxy and not so sure about dustlane 😃 Star formation triggered by merging and a slight artifact.
It is a star 😃 But not all stars in the SDSS survey are imaged as such - we do get normal ones! This was caused by a imaging error.
These are all artifacts caused by imaging errors. Sometimes the filters are misaligned or not focused. here
I would say yes 😃 #edge-on galaxy
It is a satellite trail 😃 They move really quickly so we only capture then in a single filter, in this case red 😃
The dot is a star from our galaxy - I guess alan1001 was referring to the extended arm at 2 and 12. Not disturbed for me, 3 arms?
Not a 'gpair' - a galaxy and a foreground star. Only hashtag objects you are certain about 😃 For the newbies:-)
The filters could of been misaligned, there could of been bad observing conditions (eg. very windy) or a technical problem with the scope.
Not a lens or a merger 😃 I would go with spiral arm. Clearer if you view it in the different filters.
An artifact:-) If you have a look at the skyserver image we are clearly in the middle of a star cluster. All the objects here are stars 😃
Two galaxies merging 😃 Simbad has it flagged as a AGN as well. Nice!
It is 2 separate objects, in this case foreground stars. Look like the observing condition were not that good, hence the fuzzyness.
I would say no 😃 No interaction between the yellow galaxies and all the other objects are foreground stars 😃
It is a spiral galaxy with a really bright core. Possibly also contains a bar 😃
The galaxy is very disturbed but it is difficult to tell if the galaxy at 11 is involved. No spectra for either. My gut says no...
The galaxies are not overlapping 😃 To call it an overlap they will need to cross over each other with no interaction. Line of sight 😃
No worries 😃 #no_lens
It would be nice to see a bit more curvature in the arc, but a nice addition to the collection 😃 Now to try and find the counter image!
Neither 😃 Looks round to me - it is only due to a slight colouring artifact (red on left, yellow on right) that is has that appearance.
I thought as much 😃 Another one to add to the glossary that is being compiled 😃
FOV = Field of View 😃
Not enough curvature for it to be a lens - I would go with #overlap #no_lens
#no_lens #ringed galaxy

The object to the lower right is a foreground star - they tend to be more clearly defined than galaxies 😃
Imaging artifacts 😃
They are all foreground stars from our own galaxy - widescreen view here Click on 'Get Image' on left.
The orange object is a foreground star from our own galaxy - so it is not connected with the blue galaxy at the center 😃
They are also galaxies, looking at the colour a lot more distant than the central galaxy 😃
That dark ring is an imaging artifact caused by the ccd camera being overwhelmed by the brightness of the core (over saturation)
It is a star in our own galaxy, so it is close compared to the galaxy at the centre 😃
Galaxies are more diffused than stars, also the weird colours above are tell tale signs of artifacts caused by stars 😃
No 😃 You can't change your classification once you have submitted it. Have a read of this thread here
Hi and welcome @stefku - they are both foreground stars, so no merging 😃 In future you can classify it as a star / artifact 😃
Some galaxies are just irregular / asymmetric in shape 😃 I can't see anything interacting with it. #irregular for me too.
link the image is slightly rotated, and you may have to click on get image (on the left)
It is a diffraction spike from a bright star just off screen to the right - a #artifact 😃 I will post a link to the widescreen view...
Another foreground star from our own galaxy - #artifact 😃
The bright object is a foreground star - just tag as #artifact 😃
I would of classified it as a star / artifact 😃 something went very wrong with the imaging.
I will get someone to have a look 😃
All foreground stars 😃 The weird colour is due to a error with the green filter in the telescope.
Nice #bar 😃
It looks like they are unconnected - I would say the edge on is a lot further away than the central galaxy.
It is a artifact - a foreground star 😃 The brightness caused some issues with the optics of the ccd camera.
It is a diffraction spike from a star just off screen 😃
It won't be a dwarf galaxy - wrong colour and too big! Could be a companion galaxy or a foreground star 😃
Stunning! 😃
Personally I am not entirely convinced the object at the bottom of the galaxy is a star...
A galaxy directly at the center - they are more fuzzy than stars. NED has the other two objects as foreground stars. #asteroid on right 😃
Clearly two separate objects, and NED is not always correct! . The whiter object could possibly be a foreground star?
I would go with dwarf galaxy 😃 There are quite few references on NED for it.
I would say foreground star - to well defined to be s satellite galaxy. No spectra so there is not much else we can learn from the object.
Yes they are all foreground stars 😃 The strange colour is due to a filter / imaging error.Sorry!
Hi Thom and welcome 😃 It is two galaxies that are in the process of merging, hence the distortions and starbursts (the blue bits)
Then classify it as such 😃 It is your opinion we are looking for after all 😃
A foreground star 😃
I am more inclined to go with a spiral galaxy, see how the points are very angular and the arms extend futhur than the ring?
Just a single galaxy 😃 The white object is a foreground star from our own galaxy.
Star formation in a irregular galaxy - if you scroll down you can see you are not the first to query it 😃
I would go with spiral arms - see how they don't make a perfect ring?
Spectra flags it as galaxy, the blue ring could be star formation but I would still err on the side of caution and tag as possible #lens
Too fuzzy to be a star, certainly a galaxy. Interesting blue ring, needs a closer look...
You might have to click 'get Image' after following the hyperlink 😃
Yes, it is a diffraction spike from a foreground star off screen to the left. Have a look here for the star..
True, but sadly there is nothing we can do about until Talk gets revamped 😃
Welcome 😃 Only ever classify the object directly at the center, in this case a smooth galaxy . That bright object is a foreground star.
I would go for star as well 😃 Looks like was an issue with the green filter.
I have answered you in the discussion thread 😃
ps that is a little bit uncalled for 😃
How far upper right?
No spectra? To be honest this looks like a pretty ordinary galaxy...
AGN? why?
One for the #alphabet 😃
No merging for me 😃 The star on the left is from our own galaxy -it only looks connected by line of sight 😃
#no_lens
#no_lens
Actually, I would call this a Low Surface Brightness (LSB) galaxy or dwarf galaxy.
It is a spiral galaxy with loads of star formation - that is what is causing the blue colour 😃
It is another galaxy 😃 From the looks of it, it is not connected to the central galaxy 😃
#no_lens foreground stars.
#no_lens
I would go with overlap - although it is very fuzzy, we do not have much interaction.
Looks like foreground stars - something went very wrong with the filters!
The black dot is a artifact caused by over saturation, we have this problem with really bright objects 😃
It is rather disturbed, looks like we have a sattelite galaxy to the lower left 😃
I would say the two lower 'nuclei' are foreground stars 😃 They only look connected to the galaxy by line of sight.
I am not so sure it is barred - the image is very fuzzy. but I do see a spiral pattern. Apart from that there is not much we tell 😃
Your classification sounds good to me 😃 I might of excluded 'irregular' - but that is just me 😃
#no_lens

I will try and dig around some more...
#NGC According to the papers cited it is star formation triggered by merging galaxies, but it also looks a bit odd in my eyes...
The blue bits in the galaxy are area of dense star formation. The white spot a foreground star. No merging for me 😃
Most likely foreground stars from our own galaxy - the telescope misbehaved and we landed up with these artifacts 😃
These are all artifacts - something went wrong with the imaging. Most likely foreground stars 😃
No spectra but we can see interaction between the two, early stage #merger. Nice!
#NGC
The object at the center is an elliptical galaxy with a bright core. All the other objects are foreground stars 😃 Very Fuzzy image!
Nice barred spiral - definitely not a edge-on galaxy 😃
Stunning galaxy 😃 #barred #spiral
The bright object at the top of the iimage is a foreground star from our own galaxy 😃 Nice barred spiral at the center!
This galaxy has spiral features 😃 They are somewhat blurred, but still visible. Have you tried looking at the inverted image?
No worries 😃
I am in two minds about this - I would call the outer 'ring' a psuedo ring, but the inner one looks a bit more convincing.
This is a foreground star from our own galaxy 😃 The odd colouring is due to imaging errors. More info here
I was just posting in that thread!
Disturbed isolated galaxies: indicators of a dark galaxy population?
#UGC 04722 - several notes on NED, looks like this on has caught the interest of several astronomers 😃
I can't see another galaxy in the vicinity on SkyServer - perhaps a result of a fly by?
More info in this thread here
Classify it as a star / artifact 😃 This is a star from our own galaxy, the weird colours are artifacts caused by over saturation!
This is a galaxy - so it is made up of billions of stars 😃 Looks like a stunning #ring galaxy with a #bar and a lot of star formation!
It is a bit too orange and 'regular' to be an irregular galaxy 😃 If it was blue with loads of starformation and a very irregular shape...

Not a overlap 😃 A foreground star and a young galaxy with a lot of star formation...
#no_comet - it is a asteroid...
Um, this is not an elliptical galaxy...
Sorry - not a ring 😃 Spiral arms...
Unlikely to be a overlap.. looks like we have interaction with another galaxy off screen.
Most merging galaxies do eventually combine, but this looks like an overlap 😃 ie. they only looks close together due to line of sight 😃
No bar for me! Nice 2 armed spiral 😃
Sorry! It is not irregular enough to be an irregular 😃 Also lacks the vivid blue colouring. I would go with disturbed 😃
They are all foreground stars from our own galaxy 😃
It is a foreground star, read the comments below 😃
Only classify the object directly at the center!

That is a pretty one 😃 Nice find!
I thought so, but is doesn't explain the similar blue objects 'lower' down in the skyserver image.

That would be my initial reaction, but I am not so sure 😕 Very clean and precise, fits the SN profile. Perhaps someone can have a look?
The answer is revealed below 😃 Read this here for more info.
Spectra suggests a #QSO - will wait for a professional to evaluate...
Looking at the image in different filters makes me more undecided - the blue bit at the center looks unconnected.
That is a odd one! I will get a scientist to have a look 😃 I was thinking merger, but I am not sure 😕
#irregular
Possibly - might have to wait a million or so years 😄
Wow! That is a stunning neighbourhood 😄
Only ever classify the object directly at the center! Ignore all other galaxies unless they are interacting with the central galaxy! 😃
I think you mean #no-bulge 😃 I would personally go with #irregular
Difficult to say - but I would of classified it as having a bar 😃
Have a read of this thead here - these are artifacts of foreground stars 😃
It the computer that thinks it is a galaxy - that is where we come in 😃
...certainly nothing to do with redshift 😃
@shaunessey - Hi and welcome - have you read that link I sent you in the other comments? The colours are artifacts, due to the filters...
Sadly not 😃
Read answers below 😃 Not a cluster or an irregular galaxy.
Lateral or vertical? Looks like an artifact either way 😃 Loads of background noise to go with it.
Read this here for more info on artifacts 😃
No merging - we have a foreground star on the right and there is no interaction between the galaxies. Looks like different redshifts too...
#no_lens - these are all foreground stars 😃
Just a foreground star that looks like it is next to to a much more distant galaxy, all due to 'line of sight' 😃
The blue object in the right corner? That is a foreground star 😃 Have you read this thread here ?
I would go with galaxy 😃
Artifacts caused by imaging / filter errors - have you read this thread here? 😃
And you would be right 😃
Neither 😃 both of those objects are foreground stars from out own galaxy. More info in this threadhere
Zoomed out http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=356.1143653&dec=67.32301473
An artifact - looks like we has a problem with the filters / imaging. Usually happens at the edge / ends of the stripe.
They are all foreground stars 😃 looks like a star cluster!
The core or bulge does look a bit off center - I can also see some spiral features 😃
Looking at the SkyServer image it is still very fuzzy! It is listed as a star, but that may not be accurate. Happy Hunting 😃

the object directly at the center (that you need to classify) is indeed a star. The elongated object to the left is a galaxy 😃
It is still a galaxy - I would go with a low surface brightness (LSB) or dwarf galaxy. Does look a bit irregular too.
The blue bits are regions of intense star formation. Really nice #irregular galaxy 😃
They both look like stars but it is really difficult to tell what they are, due to filter / imaging errors 😃
More info in this thread here
Just classify it as a star / artifact - which it is 😃 It is one of the images that is at the edge of the survey area.
😄 I will post more details in the collections thread in a bit...
No worries - I am just at the beginning of my quest to standardise all hashtags - so we can build better collections!
Less confusing rewrite done!
...for the collection, because that was the request from one of the volunteers 😃
'Boxy', 'X-Shape' or 'Peanut' all refer to the same type of bulge seen in a edge-on galaxy, I chose 'x-shaped' for the hash tag...
You should nominate it for the galaxy of the week 😃

...another vote for #polar-ring 😃
We usually use the term 'diffraction spike' to refer exclusively to artifacts generated by the telescope optics around stars...
This one certainly looks a bit more x-shaped 😃
The UKIDSS images can be a bit misleading, looking at the SkyServer image I would say no, but it could go either way.

Hi MikeOborn 😃 We only use the 'overlap' tag when referring to galaxy / galaxy overlaps. Bill Keels thread on the forum has more details.
I am thinking artifact perhaps? Only in one filter.

@mrgiezen - I just realised you were talking about the 'dust lane' - yes, it is more visible in the lower one 😃

The bar have a lot of star formation going on, that is giving it the slightly odd colour pattern.
Irregular galaxies tend to be blue in colour with loads of star formation and irregular shape - would go with spiral galaxy in this case:-)
The bright round object on the top left of the galaxy is a foreground star 😃
PhotoZ (although not that accurate) suggests they are not that close.
I would go with overlap, no visible interaction between the two, even though we have a lot of starformation in center galaxy.
You are right - it is a galaxy at the center! Nice work 😃
I would say both the galaxies are unrelated to each other, so no interaction for me 😃.
They are all foreground stars from our own galaxy 😃
nice one!
No nebulas 😃 Looks like we have spiral arms with load of starformation, folding back on themselves.
We have a elliptical galaxy at the center, with a foreground star to the left 😃
WOW - #zgotw for me 😄
A galaxy for me! The colour distortion is a artifact caused by oversaturation of the really bright galactic core 😃
The red / orange objects are both foreground stars - have you read this thread here for more details? 😃
I would go with a foreground star - the weird colours are an artifact caused by overexposure 😃

Thanks Phil 😃
I am still curious...
lol - apparently I am being observed with my musings 😄
awesome 😃
Artifacts from imaging. Foreground star 😃
Where about? so I can have a closer look?
Looks like we had a filter problem! In future classify as a star/artifact 😃
😃
Aahhhh, just tag it as a LSB - I am working on standardising hashtags!
Dark object where?
I do not think they are merging, the colour of the spiral (on the right) suggests it is much closer 😃 #overlap for me!
A planetary nebulae... supernova remnant 😃
#zgotw for me! Looks like we have a #bar as well! Nice 😄
It does look like they are interacting! Stunning irregular, and it looks like we have a hint of a bar! #bar
This can be better be taken up in a discussion.
Certainly. ElisabethB will post the relevant bits - provided we get Bill's permission.
2/2 and after receiving a reply from Dr Keel, please continue to tag overlapping galaxies as 'overlaps'. Other tags may be removed. Thanks!
1/2 Just to clarify 😃 My comments were directed towards the continued misuse of a specific hashtag, not in reference to the image above...
2/2 ...within professional astronomical circles. We should adhere to recognised terms to prevent confusion.
1/2 @lostlens Please can you refrain from tagging overlapping galaxies as 'keeloverlap' - they are overlaps, and referred as such...
An #irregular galaxy 😃 Another vote for #zgotw
I would go with #merger 😃
How so?
It is an #artifact caused by dodgy filters and a foreground star 😃 More info here
#zgotw
In this case I am more likely to go with it not being an x-shaped bulge - but like you said very dim.
No worries 😃
Those are most likely artifacts 😃
Yes 😃 the central object is a galaxy, the other objects are stars.
😃 Looking at it from a particular angle, it could be a very small #collisional-ring [21], that could explain the intense star formation
Collection thread here
Never said it wasn't a 'x shaped' or 'boxy' bulge 😃 We just need to all use the same hashtags to create collections.
Can we please keep the hash tag for x-shaped bulges to #x-shaped - as explained in the collection discussion. Thanks 😃
#zgotw
@lostlens - perhaps you should create your own hashtag for non-galaxy line of sight coincidences?
Doughnuts! Yum 😄
#zgotw
Not a nebula 😃 A stunning irregular (possibly dwarf) galaxy with a lot of star formation.
Doesn't look that disturbed!
They are all foreground stars from our own galaxy 😃
Blue in galaxies indicate star formation, but I think all of these objects are foreground stars 😃
I would say foreground star 😃

Part of the cosmic scarf 😃 It is a image from the end of the stripe.
The star is from our own galaxy- The Milky Way - so it is closer to us than the edge-on galaxy at the center.
Another artifact - we seem to be getting a lot of them today!
It looks like the 2 green dots are artifacts - only visible in the 'r filter
#artifact - only visible in the 'r filter - particle strike not removed.
No signs of interaction - no merging for me 😃
No, it looks like the center galaxy is overlapping a more distant edge-on.
#zgotw for me 😃
I think you are right 😃 Interesting satellite galaxy...
Wow - that is a stunning one!
Hi @davidmarine and welcome 😃 causes what?
A coincidence or chance alignment 😃 A mixture of foreground stars and more distant galaxies.
Not so sure the galaxies are merging, not a lot of interaction 😃 Overlap perhaps?
Looking at the other bright objects in the field - I will go with artifact. Misalignment of filters - Sorry!
Yes, looks like a edge-on, or disk - somewhat disturbed. Nice dust lane as well 😃
I would go with spiral 😃
What a stunning #merger!
Foreground star for me!
Line of sight, perhaps? 😃 No visible interaction, so we can rule out merging. Also, remember to only classify the object at the center!
I would say yes 😃 looks like a almost edge on spiral.
Elliptical galaxy 😃
Between what ??? Sometimes we need more clues as to what you are referring too! 😃
Not an irregular galaxy 😃 Irregulars tend to have a lot of star formation, so are blue in colour. Also they are very irregular in shape...
All artifacts 😃 Read the other comments below.
No, looks like an artifact. The other objects have similar discolouration in the lower left quadrant.
Clearly a #merger.
Discounting the foreground star, more like a satellite galaxy.
I am going to go for 2 foreground stars, if you look at the wider image there are a lot of similar objects 😃
No sign of gravitational lensing - a stunning barred spiral 😃
I would go with disk, but we are interested in your opinion 😃
A star - Skyserver is not always correct.
Why do you think the galaxy has an AGN? Interested to hear your view... For me, it is a typical edge-on, No AGN.
It is a foreground star 😃 Something went wrong with the imaging so it looks weird. More info here
Those funny colours on the star on the right are artifacts - looks like some of the filters were misaligned.
You are correct we do have a star on the right 😃 At the center a stunning #barred #spiral. No signs of merging.
Nice!
All foreground stars from the Milky Way 😃
Hmm, I would not say irregular, rather star formation is giving the arms a clumpy appearance.
The purple object is a foreground star from our own galaxy 😃 More info here
Looks like we are in the middle of a star cluster, so it is quite possible one of the objects is a foreground star overlapping 😃
A foreground star from our own galaxy. more info here
From @klmasters: "we usually reserve the term disturbed for things which are very asymmetric."
In order to classify a galaxy as 'disturbed' you need to look at the shape of the galaxy, not the colour.
Neither - just a very fuzzy almost edge-on spiral galaxy.
#artifact - only visible in 'r filter. Cosmic ray that has not been removed.
#UGC
No spectra available, and it does not have the characteristic colouring of a AGN. I am more likely to say no, just a bright core 😃
More likely a #merger 😃 Look at the interaction between the galaxies, in particular the tidal tails of the upper galaxy.
Agree with @elizabeth - certainly not disturbed!
Not a voorwerpje - star formation in a spiral galaxy.
#artifact at the galactic center caused by over saturation - more info here
Not a voorwerpje - an orange foreground star overlapping the central galaxy.
It does not have the vivid colouring of a voorwerpje - more likely a foreground star overlapping the edge on galaxy..
They are all foreground stars from our own galaxy - more info here
Thanks @C_cld - was having supper, so was a bit busy to look! 😃
Not lensing or a recent merger. Colour is worth a closer look.
Yes - artifacts 😃 All the objects in this image are foreground stars - more info here
I would go with an #irregular galaxy with #star-formation. Can't see anything else that could be interacting with it 😃
Not a binary system 😃 Perhaps it has the appearance of being disturbed as it is a 3 armed spiral 😃
#NGC
#merger
#UGC 8973
The object directly at the center is a galaxy 😃 The other objects are all foreground stars. More info

More of a whitish blue, for me 😃
green?

The colours are not real, it is an artifact. The object is in fact a foreground star. The weird colours are caused by a imaging error.

I am not seeing anything that suggests this galaxy has a AGN - no spectra, and it is not displaying the bright core one would expect 😉
I am not seeing any signs of lensing? Where about are you seeing it? 😃
Not a merger, we have a foreground star to the lower right and a lovely elliptical galaxy at the center.
Yes 😃 A foreground star.
More likely just star formation triggered by interaction.
#round_bulge
Foreground stars 😃
They are both foreground stars from our own galaxy. There was a imaging error,so we have some colourful artifacts 😃
@lostlens - last warning. It is not a overlap!
The core only looks unusual because of the color difference between the arms and the core. Apart from that, it is fairly non-de-script.
To do that use a # and follow it with the word asteroid.
No dust lane for me 😃 but I do see an asteroid bottom left - flag it 😃
Not an irregular galaxy - both sides are symmetrical 😃 The slightly blue color in the arms can be attributed to star formation.
The object at the center is a lovely smooth or elliptical galaxy 😃 The bright orange object is a fore ground star - Welcome to the Zoo!
They are stars from our own galaxy 😃
These are artifacts caused by an imaging error. All the objects are in fact foreground stars from our own galaxy.
#xshape
I am going to go with star formation triggered by interaction - see how part of it follows the pattern of the spiral arm?
No arc for me 😃 Looks like stars that have been disturbed from the galaxy due to interaction. Lovely merger!
That is a dustlane 😃 Dust in the galaxy is obscuring some of the light reaching us, causing a dustlane
That looks like a foreground star, no galaxy for me - sorry!
Hi and welcome 😃 That is a foreground star from our own galaxy!
Something went wrong with the imaging / filters - both of these objects are foreground stars 😃
A foreground star from our own galaxy 😃
Yes, it is 😃
#boxy #x-shape
Stunning! 😃
No it does not look like a lens 😃 It is a galaxy with spiral features, a bar and with an very faint outer ring or arms.
#edgeon too! 😃
I would like it looks more like 2 spiral arms crossing back over themselves, than a ring 😃
Sure looks like one 😃
#UGC 11611
No lensing for me, the colour between the lens and 'lensed' object are too similar, suggesting similar redshift.
If we compare the PhotoZ (even taking possible errors into account) of both objects, it is unlikely they are connected.
As mentioned by a previous poster 😉
I don't see anything it could be interacting with. I think the star is just masking the opposite arm 😃
Simbad contradicts itself by also identifying as as G1C - Galaxy in cluster. Mistaken identification?
No spectra and apart from a bright core, there is not a lot to suggest this is a QSO. Sorry 😦
I would go with #cluster - not a lot of interaction so I say gravitationally bound rather than merging 😃
I think it is a galaxy, as it not as well defined as a star. Loads of artifacts in this image - must of been a #windy_night #misaligned
A foreground star 😃
forgot to add - loads of star formation 😃
It looks like a single barred proto spiral galaxy to me - but it is your choice 😃
No merger - the object on the left is a foreground star 😃
With images like this it is difficult to tell. Certainly a bar,not so sure about the ring.
I would go with #merger myself - we seem to have interaction between the center galaxy and the one to the right. Also star overlapping 😃
The blue colour does suggest that it is relatively young - we have clumps of new star formation - Nice!
No planets! To the right is a star. At the center is a very bright galactic core.
The blue areas in the galaxy are regions of intense star formation 😃
Yes, that blue object in the top right is a star 😃
These are all foreground stars from our galaxy - more info here 😃
It is visible in more than 1 filter, so it not an artifact. #voorwerpie? I don't know enough about them to say:-)
#NGC 7731
It is currently on hiatus, we will be getting a new survey later this year. Can't wait!
We found several new ones over on Spacewarps - my pet project 😃
No, chance alignment for me. The colour between the objects are too similar, suggesting similar red shifts. 😃
I think they are unrelated, and it is just by line of sight they look like they are merging. Nice irregular at the center 😃
We do seem to have some slight spiral features, but the resolution of the image is quite bad. Just classify what you see!
Another foreground star - has you read this thread
here - more info on the different types of artifacts 😃
A foreground star from our own galaxy 😃
Quite disturbed - #merger for me
SIMBAD has it listed as a possible AGN, can't find any spectra...
#round_bulge
Not entirely convinced it is one armed - personally I would classify it as two-armed 😃
It looks like it 😃 Stunning #merger
Mid lower left? SkyServer has it listed as a star.
I am not so sure this is a merger. The image is low resolution, so it is difficult to make out features, result of a fly by perhaps?
That's a stunning one! #ZGOTW
They are all #artifacts - something went wrong with the imaging. Sorry!
A foreground star from our own galaxy:-) More info in the discussion you posted 😃
I would go for disturbed disk or spiral galaxy. No lensing for me!
Nice spiral galaxy, I am not seeing any dust lanes? Are you referring to the darker areas between the arms?
I think those are spiral arms:-) No dust for me!
That is an artifact - looking at the SkyServer image we seem to be in the midst of a star cluster 😃
Only classify the object at the center! In this case it is a galaxy. The other two objects are foreground stars 😃
That is a galaxy 😃 Looks a bit disturbed, sadly no spectra available.
An error with the imaging - looks like there was a problem with the green filter. Sorry!
Sure looks like one, SIMBAD agrees 😃
ooopsss - sorry!
Els has several hundred thousand galaxies classified 😃 But she is not one to brag 😄
#ZGOTW
...or a Klingon ship de-clocking 😃
That is unusual! I am not sure if it is a polar ring, as the 'ring' seems more established than the galaxy. Reverse maybe?
Either way, I will get someone to look at it 😃
2/2 the blue colour (star formation) is also a good sign of interaction. Really difficult to tell. Could also be pure chance!
1/2 In this case I might go with early stage merger. The smaller of the 2 galaxies is starting to look a bit disturbed in the lower left...
#NGC
No worries! 😃
Not a lot of interaction. I think gravitational bound, or totally unrelated is more likely 😃
I would go with overlap, the edge-on to the lower right is a lot further than the central galaxy 😃
Pink colouring looks like an artifact, not likely to be a lens. Have you had a look at the SkyServer image for similar artifacts?
Not entirely convinced it is a ring or barred - there is some suggestion of a polar ring, but not entirely convinced 😃
An error with the telescope- it happens from time to time 😃
It is still fairly symmetrical, so I personally don't think it is disturbed 😃
@Lostlens we have spoken about you deleting and reposting comments, please could you stop doing it. Thanks 😃
Looks like one to me 😃 Maybe early stage, only slight interaction between the two.
Not seeing any obvious signs of interaction -more likely an overlap 😃
Yes, it is a foreground star 😃 Looks like the galaxy may have a bar forming?
lol - that's an awesome one 😃 An imaging error, looks like something went wrong with the filters. One for the Art thread!
They are all foreground stars from our own galaxy - The Milky Way 😃 Have a read of this here BTW Welcome 😃
That is an artifact caused by over saturation 😃
Stunning! 😃
Looks like we have 2 foreground stars overlapping a more distant galaxy 😃
#round_bulge
Not lenticular - a edge on disk / spiral galaxy. Lenticular galaxies are a mix between a disk and smooth galaxy 😃
It is an #irregular galaxy 😃 I am not seeing any signs of recent interaction. Happy Hunting!
Wow - stunning a #ZGOTW for sure!
Not lenticular - an edge-on spiral / disk galaxy 😃 The bulge looks #boxy #x-shaped - nice!
That is a diffraction spike from a bright star off screen to the left 😃
Looks like we do have some interaction with the left galaxy. The galaxy to the lower right looks unconnected 😃
Yes 😃 a foreground star.
Stars 😃
Looks like a merger for me - interaction and star formation 😃
lol- Liz will love this one 😄
I would say so, looks like we have several foreground stars in the image. 😃
Does look like a bar and ring, pity the image is not clearer 😃
A star 😃
I am more inclined to go with merger 😃 We have a lot of starformation, that can get triggered by interaction between the galaxies.
yes 😃 the algorithm sometimes gets confused!
The tiny blue 'star' looks like a star burst - nice!
#round_bulge
A star 😃 Something went wrong with the imaging, so we landed up with this spectacular artifact!
Yes, the bright orange object is a foreground star overlapping a much more distant disk galaxy 😃
I would go with star 😃
LSB is another option.
Hmmmm, I don't think it is disturbed, as I cant see anything else interacting with it. Young proto spiral perhaps?
I would say it is a two armed spiral. The arms are wrapping back on themselves so it gives the appearance of a ring.
That is a very long tidal tail!
That is a good one - looks like an E5 #elliptical galaxy to me!
Nice! #overlap
Not a lot of interaction, but certainly gravitational bound. A lot of artifacts, and the image is heavily processed.
Not so sure about the bar,but definite spiral features 😃
@lostlens really? overlap? Interaction is quite obvious. How do you quantify it as being an overlap?
That is an awesome one! 😃
Not so sure, could be a foreground star. Have you had a look at the individual filters?
That happens to me all the time! Lovely smooth E7 ? galaxy at the center.
That is a nice one!
#boxy to boot!
#merger for me!
Sorry - not likely 😕 Just looking at the colour the central galaxy is a lot further. No interaction.
No arc or ring for me 😃 a 2 armed spiral. The arms are folding back on themselves, that is why it looks like a ring 😃
zoomed out image : http://tinyurl.com/qa3cm9o , you might need to click 'get image'' 😃
The blue blobs are areas of star formation.
Wow - I would go with spiral/ disk, 2 arms and yes, there is something unusual.
#merger
No worries 😃 And Welcome!
Unlikely to be a merger- no interaction. No other data to support it.
The blue object in the 8 looks like a foreground star.I am inclined to think it is not a merger, but I will have a closer look...
Yes, a foreground star!
I was tempted to go with #irregular - but there is too much symmetry. No ring - spiral arms. Early stage spiral?
#edge_on #round_bulge
stunning #edge_on #no_bulge
It is a cluster - slightly different. Very similar to one of the new official SW candidates that got modelled last year 😃
#asteroid
Nice one!
It is a galaxy - it looks a bit weird as we seem to have a star overlapping in the top right corner.
Not a nebula - a galaxy. Looks like a dwarf to me 😃
I am thinking the same thing- I will need to have a closer look. following
Not a lot of interaction, so I would go for gravitationally bound i.e. a group or cluster
#Merger 😃 The blue areas are star formation triggered by the merge. No gravitational lensing! #no_lens
I am more inclined to go with overlap. I can't see any visible sign of interaction. Also, colour suggests the edge on galaxy is a lot futher
Looks like another galaxy to me 😃 voorwerpies will have more intense colouring.
I am not seeing any lensing in this image - just a gorgeous merger 😃
#round_bulge
Even though this isn't a galaxy #ZGOTW 😄
Once again a galaxy and a foreground star 😃
The galaxy at the center has a #bar and a #ring - the bright blue object is a foreground star.
It does look a bit disturbed!
Correct! the object at the center is a galaxy, and the blue object is a star. It only looks very bright because it is so much closer!
You are correct they are all stars, but they only look connected due to line of sight 😃
That green bit looks like an artifact as it is in only one band. The larger blob at 6 is a galaxy. As too wether they are merging - unclear.
I don't think it is a merger per se 😃 We have star formation, possible satellite galaxy to the right. Not an irregular.
The round object is a foreground star, the disk does look somewhat disturbed but the image is very low res - must of been a windy night!
#UGC
That does not look like an LSB for me 😕 I know SIMBAD says it is one, but I think that is a bit misleading.
It's designation is 2MASX J08072045+0357156 , and it is a smooth / elliptical galaxy 😃
They are satellite galaxies of the larger one at the bottom of the image 😃
#NGC
@lostlens - you do not need to comment on every image you classify - just the ones you find interesting. Thanks 😃
That is a foreground star from our own galaxy 😃 More info here
And Welcome to the Zoo 😄
That does look interesting! Possible #lens candidate for me 😃
Are you talking about the line between the galaxies? I don't think it is a gravitational lens...
They are both galaxies 😃 The bright blue areas are starbursts (areas of intense star formation).
All sorted... some people should not be allowed to drink.
Oh sorry Liz - got distracted. Had to call the police for a situation outside my flat...
Hey Liz, I don't think Els was referring to you 😃

I am not so sure about boxy 😦
This thread has more information here
Welcome Pin Valentine 😃 That is a foreground star from our own galaxy 😃
Not too sure - I tend too associate polar rings with spiral galaxies, this looks like an elliptical. Scientist?
I would go with #merger - the spiral at the center is very disturbed 😃
A satellite trail 😃 More info here
I would go with overlap, and I am not a professional either 😃
One for Liz's art thread!
No lensing 😃 There is another galaxy just off screen - looks like a tidal tail. (There is also a diffraction spike to the right)
another #boxy bulge!
#UGC
That's a difficult one - instinct says spiral, but it does have ring features - although I would expect a ring to be smoother.
#NGC 7345
That looks like a foreground star but amazing #boxy bulge!
That is an elliptical galaxy - the bright ball is the core or hub of the galaxy 😄
here it is: http://www.galaxyzooforum.org/index.php?topic=273513.0
Sadly, there is no Spectra available for this star - but there is an excellent archived thread on the old forum to do with White Dwarfs 😃
The colours of the stars are not real, there is a lot of processing that goes on too enhance the images. Have you looked on SIMBAD?
Wow! definately #ZGOTW
I don't think it is a diffuse nebula 😉 More likely an imaging / filter error.
wow,that is one disturbed spiral! Possible flyby or early stage interaction with the galaxy on the right?
Not seeing a lot of blue and no spectra, so I am going to go with no 😃
a planetary nebula 😃 A remnant of a star.
Looks like a low surface brightness (LSB) galaxy #UGC 31
Looks like we have a star (the round object) from our own galaxy overlapping a much more distant galaxy. Info
That is a foreground star from our own galaxy 😃 More info on artifacts here
I am more inclined to think overlap, as there doesn't not appear to be much interaction. Possibly gravitationally bound?
#irregular for me
I would say so 😃 Nice tidal loop!
Supernova - No.
Ring - looks like it! 😃 Hint of a #bar as well!
You are correct #artifact caused by over saturation 😃 I am sure I have seen you around before ???
Classifying this image I would say no, looking at the wideview SkyServer image I would say possibly. We need to differentiate btwn the two.
Not really 😃 more about the emissions themselves. I am not a spectra expert - prefer GL modelling. For spectra @budgieye 😃
just classify as a star/artifact - the algorithm gets thrown off by bright objects such as stars.
No worries! There is still loads of spectra available on SkyServer, but sadly not for these galaxies! 😃 I will keep digging...
... from visual observation. I guess I don't need to say this, but Skyserver can sometimes be incorrect 😃
Aahh, I see where you are looking! Very rough estimate, with no spectra to back it up, very unreliable. I do think it is a merger...
top right?
Where about on Skyserver? There are several 'z' values that are not actually redshift values 😕
Are you looking at SkyServer for the redshift?
I think I would go with a spiral - the arms look like they are rounding back on themselves. Looks like we have a bar too 😃
a central bulge 😃
Not edge -on 😦 Nice spiral or disk galaxy 😃
Looking at the different filters, I would say it is more likely to be star formation in spiral arms. #no_lens for me personally.
I would go with #starformation myself!
Another one for the collection #NGC 😃
The white line is a diffraction spike from a star just off screen 😃
I agree it is a spiral galaxy 😃 The compressed objects are foreground stars.
#satellite trail 😃
To the left? That is a diffraction spike from a bright foreground star just off screen 😃
There is some slight discolouration, but I do not think it is lensing. Less apparent on the DR8 images - mmmm.
Hi 😃 Where about are you seeing the arc in the image?
That might of been the case with the UKIDSS images, but we are now back on SDSS. Also no spectra, so not much to suggest AGN. @budgie?
#NGC 5303
It is a foreground star from our own Galaxy 😃 It looks a bit odd as it is quite over exposed.
No, I would not say it is edge on. Looks like a normal head on spiral.
Yes, it is a foreground star from our own galaxy 😃
I would go with foreground stars 😃
An #irregular galaxy with star bursts 😃
That is a foreground star 😃
It is a foreground star 😃
stars 😃
There are a lot of stars overlapping the galaxy. Normal 2 armed spiral for me 😃
gorgeous #merger!
Not likely 😃 The dome would of been commanded to close before the sun rose. More likely there was a problem with one of the filters.
It is a satellite trail 😃
I don't think so - we do seem to have interaction between the top blue satellite galaxy and the central one... anyone else?
lol 😄
No, this is a lovely elliptical galaxy. Stars tend to be more defined - galaxies a bit fuzzy 😃
Yes 😃 a foreground star!
Just a very disturbed night when the observing was done - hence all the background noise!
We want your classification, no matter how incorrect! We learn a lot from every click done!
Unless you are meaning the M40 highway? A big resounding...No.
Nope.
@planetaryscience - thought you had moved onto greener pastures, after all the PM's I got last week 😃
Line of sight 😃 Same effect when you use a camera.
Why don't you post it in the Art thread in Chat! 😃
That is a nice one! #NGC
It is an #artifact caused by a foreground star.
Yes - that is a star up top! 😃
@flyaway - no worries!
I would go with foreground star 😃
You can read more about them here
The top and right objects are both foreground stars from our own galaxy 😃 The green/red/blue object at the bottom is a asteroid!
#bar #spiral possible #inner_ring
@flyaway - Hi and welcome 😃 What object are you referring too?
#UGC 123
It is a galaxy 😃 I would go with a low surface brightness (LSB), irregular galaxy. Does have a spiral pattern of sorts...
Not a super nova - but a foreground star! 😃
That's right! Two foreground stars 😃
It is a galaxy directly at the center, with a foreground star to the lower left of it 😃
#NGC 0102
#ZGOTW
Wow - with a #bar as well 😃
Yes 😃
They all look like foreground stars 😃 Have you read this thread: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
I only see a single spiral galaxy 😕
The bright blue bits in the arms are regions of intense star formation or #star_bursts
#UGC 01070
Yes, I would agree the galaxy at the center has #spiral features 😃
Hi @mindstate55 - please only classify the object at the center 😃 Thanks!
certainly a #bar, possible #ring
Yes, they are all #stars 😃
I think I agree with @C_cld - shell galaxy?
We really do need an Art thread!
No 😃 It is definitely a galaxy - looking at the colour, fairly young. Looks like we have star formation going on.
Nice one! Congrats 😄
It depends on what project you post on... we are specifically looking for a galaxy 😃 Hence galaxy of the week 😃
we are using the hashtag #ZGOTW over here
See this thread: ZGOTW?
I would certainly say it has spiral features!
That is a foreground star 😃 Remember to only classify the object directly at the center - this case a diffraction spike from the star.
No lensing for me - looks like a spiral arm 😃 The blue discolouration is star formation.
Yes, that is a #diffraction_spike from a foreground star off screen 😃
I would say #spiral - not very well defined, but certainly too many features for it to be an elliptical. Agree with #odd 😃
#ZGOTW
... What is ZGOTW?
I would go for #boxy as well 😃
It is a satellite trail 😃
#ZGOTW for me!
... What is ZGOTW?
I don't think so 😕 - I would still classify it as smooth / elliptical
Most galaxies do contain black holes - but we would not be able to see them on these images 😃
Another galaxy 😃
I would go with #overlap - you can see the dust lane extending over the galaxy on the right.
You can also add comments to a individual object within a collection 😃 Very Useful!
Yes - you can view it in the collection. By the way you can follow a collection, so it is easier to find!
Yes - they are all foreground stars 😃
lol 😃 No sadly just a foreground star!
Unlikely to be gravitational lensing. I am thinking star formation - spiral features, but... - very interesting galaxy. I will flag it up!
Image is very fuzzy - my vote is a foreground star or satellite perhaps?
#bar #spiral #star_forming #stunning 😃
Does this work better?
A #ZGOTW for me!
... more info here
lol - click on the link in the comment 😃 It was a rhetorical question - but I think I might have to change the wording!
Wow - that is a stunner!
#ZGOTW
... What is ZGOTW?
Good to see you Claude 😃
The dark spot? That is an artifact caused by over exposure / saturation.
That's right! A foreground star 😃
But, here on talk you can ask about anything in the image!
The orange one on the right? That is a foreground star 😃 Always remember to only classify the object at the center 😃
...possibly a foreground star?
A smooth or elliptical galaxy 😃 There is something a bit odd on the right hand side - also in the SkyServer image...
lol 😄 All foreground star from our own galaxy. The SkyServer image is pretty awesome!
#ZGOTW
... What is ZGOTW?
#ZGOTW
What is ZGOTW?
#ZGOTW
I think I might ask @mrniaboc if this could be the galaxy of the week 😄
Another WOW 😄
😄 I never this many gorgeous galaxies to classify in a day! What is your secret 😉
WOW - absolutely stunning!
It is a star cluster, but the object directly at the center is the faint orange star next to it 😃
Hi and Welcome 😃 Remember to only classify the image directly at the center, in this case the smooth or elliptical galaxy 😃
Yes:-) It is a star from our own galaxy!
The really bright object is a foreground star 😃
Wow! A piece of art 😄
The orange object is a foreground star, so it is by line of sight that it looks connected to the galaxy 😃
Artifacts 😃 Something went wrong with the imaging (in particular the blue filter) and this was the result.
#merger
Not a merger 😃 A stunning #overlap of a foreground #spiral and a much more distant #edge_on. #dust_lane in the edge on galaxy 😃
No it is not a Hanny's voorwerp 😃 #star_formation in a #irregular galaxy.
2 answers for the price of one 😄
They are both foreground stars 😃 The algorithm that selects the objects to classify sometimes gets confused with bright foreground stars.
All foreground stars - have you read the link I posted in your previous comment? 😃
They are artifacts 😃 Have you read this thread: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
This is a foreground star from our own galaxy. The imaging went a bit wrong and this amazing artefact was created 😃
But, we do seem to have some satellite galaxies. The artifacts on the right hand side of the objects are not helping either 😃
Difficult to tell as the image is really fuzzy - my gut instinct says no ,as I am not seeing many signs of strong interaction.
Not a cloud - a galaxy 😃 From the shape I would go with a smooth or elliptical galaxy.
I would say yes, Dave 😃
You are right - star formation regions 😃 Seems to have a slight #bar and looks like an #irregular galaxy
Looked at it in a bit more detail in the DR8 SkyServer image, will get a scientist to have a closer look 😃
I would go with #spiral galaxy. A very loose limbed spiral 😄
It is a loose limbed spiral galaxy 😃 Remember to only classify the object in the center, but it's okay to discuss it here 😃
Does not appear to be an artifact either. Visible in several filters #curious
A fuzzy, non-descript galaxy 😃 We seem to be getting a lot of them today!
It is galaxy 😃 Small,not many stars - I would go with #dwarf_galaxy myself, but it also be classified as an irregular.
Nice! Looks like we have some interaction going on between the two 😃
Yes 😃 it looks like a foreground star overlapping a galaxy. All the stars in the image are displaying similar artifacts.
There is clear interaction between the two galaxies #merger for me
Its a bit fuzzy and non-de-script, but it is still a galaxy 😃
Possibly a dwarf galaxy? Not much info on NED or SIMBAD 😃
Really difficult to tell - I am not entirely convinced the smaller object is a galaxy.
Ignoring the obvious satellite trail, I would personally say star 😃
It is:-) Aren't they spectacular!
Wow! - that is a stunning one 😃
A artifiact cause by a bright foreground star off screen 😃
Yes - I would go with foreground stars 😃
The blue object on the right is in fact a foreground star 😃 Always remember to only classify the central object - Thanks!
An #artifact caused by bad imaging. It is in fact a foreground star.
What a fuzzy image! It could also be a foreground object overlapping the galaxy - difficult to tell. Sorry 😃
Looks like it could be a satellite galaxy 😃 It is quite common for larger galaxies to have smaller companion galaxies.
Awesome #overlap #NGC6365B
Looks like we have a #boxy_bulge 😃 Stunning!
Yes, it is 😃
Its a artifact, we get this type when we reach the end of data set 😃
No worries! Have fun classifying 😃
Gorgeous #merger 😃 Look at those #tidal_tails
Yes, that#s right 😃 #satellite trail
Looks very disturbed - most likely due to interaction. The central galaxy also has an interesting spectra - possible AGN?
I would say it is #barred with #spiral features 😃
Looks like a satellite / asteroid trail that has been cleaned up 😃
Optical artifacts from a bright foreground star off screen 😃
#barred as well 😃 Stunning!
Gorgeous #barred #spiral with clumps of #star_formation
#merger
That bright object is a foreground star, the color and spikes are all artifacts. Have a read of this
I don't see any signs of a merger, possibly a proto spiral? We can see some faint spiral features.
Looks like the tracking malfunctioned during the green filter - those streak are all foreground stars!
Looks like a possible #polar_ring
#merger
Hmmm, not seeing much signs of a bar - but you are correct with #spiral 😃
That is seriously disturbed! Possible #bar like structure as well.
They are foreground star from our own galaxy 😃 Remember to only classify the central object.
I would go with #stars 😃
2/2 galaxy with a smaller satellite galaxy. Very Fuzzy image, so classifying it could not be easy 😃
1/2 Ignore the long stream - it is a diffraction spike from a bright star off screen. The 'big bulge' looks like an elliptical (or smooth)
The bright white /green / blue / red objects? They are both foreground stars 😃 remember to only classify the object in the center.
Foreground stars, again 😃 Remember to only classify the central object, but on talk it is OK to talk about the rest of the image 😃
And you are right! 😃
That is an artifact, if we look at the larger image their are a few of them running through the field, in a line 😃
They are all foreground #stars from our own galaxy 😃
I would go with #overlap 😃 Rule of the thumb. Blue galaxies - close, red/orange galaxies - far. SkyServer think the orange obj is a star
A disturbed spiral, with star forming regions. No merging for me 😃
Well done! Edge-on disk (or spiral) galaxy with a round bulge 😃
Looks like a foreground star - we have several objects scattered around the image 😃
Only classify the object directly at the center, in this case the orange elliptical 😃
The asteroid is not within frame of this image 😃 You might send some volunteers on a wild goose chase trying to find it...
Sorry - I don't see anything either 😦
Look at the SkyServer image 😃 Looks like a small part of a larger galaxy cluster!
We try not to use acronyms in the comments section - we have a lot of newbies.They will not know what you are talking about 😃
I would go with #barred #spiral - there are more spiral features than a true ring 😃
No worries 😃
Edge on galaxies tend to have pointy ends, cigar shaped ellipticals have more rounded tips 😃 This one looks pointed to me!
Looking at the image I am inclined to say foreground star - there are several similar objects in the image.
Sorry - no sing of a ring. A 2-armed spiral #no_ring
#barred #spiral with a #dust_lane - no rings 😃
I would go with artifact - they all look like foreground stars
Looks like it! nice catch!
I don't think it is a merger - The orange object is more likely to be a foreground star 😃
Nice! 😃
WOW - that is a stunning one 😃 #bar and #ring for me too!
I agree with disk at the center, but it looks like the object to the right is a foreground star.
Yes, a disk or edge on galaxy. Looks like we might have a bit of a dustlane 😃
I would go with #merger on this one 😃
That is a satellite trail 😃
That does look disturbed - you can see a star trail off to the left. The image also looks a bit misaligned.
That's an artifact. The foreground star tend to overwhelm the telescope and create some interesting artifacts!
Looks like something went wrong with the imaging - particularly the red filter.
Not an artifact. Satellite galaxy perhaps? The image is very low resolution,so without spectra,it is going to be difficult to tell.
Very blurry image, but I think I will go with overlap not merger. Not many signs of interaction.
Foreground stars - as the comments below suggest 😃
Sadly, they are all foreground stars. Sometimes the images we classify do not contain any galaxies.
Not a galaxy, but a foreground star 😃 The colours are artifacts caused by over exposure.
And, you would be right! Star bursts 😃
It does look somewhat irregular 😃 The blue clumps are regions of intense star formation, and we have a slight spiral structure.
It is a satellite trail - they move so quickly across the sky they only get captured in a single filter 😃
Foreground stars 😃
An artifact. This is in fact a foreground star from our own galaxy. Something went wrong with the imaging 😃
Only ever classify the object at the center! The object in the top right is a foreground star 😃
Hmm,they all look like foreground stars to me - I would of classified them as star / artifact 😃
You would be right! All artifacts caused by foreground stars and over exposure 😃
You are looking at the image directly at the center, in this case the orange blob to the right of the red line. Star / Artifact for me 😃
An #artifact caused by a foreground star and problems with imaging 😃
No lensing - just similar looking elliptical galaxies. Not much interaction between them, gravitationally bound as opposed to merging.
That right! The blue area are regions of intense star formation 😃
Yes, it is planetary nebula - more info in the comments below.
Both the blue and green stripes are satellite trails - each got captured at different times in different filters.
It certainly has spiral features, so I would classify it as such 😃
Not so sure it is disturbed - think we have the beginnings of a #bar
#starforming
No 😃 The object on the left is a foreground star from our own galaxy 😃
Only classify the object at the center 😃 In this case the star
No worries 😄
I would go with #spiral galaxy with #bar 😃
Diffraction spikes from a bright star off screen 😃
I can't find many signs of interaction, so#overlap for me
Remember to only classify the central object 😃 I would of gone with star/artifact in this case.
I am more likely to go with foreground star.
For me optical illusion - line of sight. If you look at the SkyServer image, it looks like they are in a star cluster.
I think they are more likely to be satellite galaxies - but the image is really fuzzy.
#stars
That is correct - all foreground stars 😃
All the objects in this image are foreground stars- looks like a star cluster in the SkyServer image.
That object is a foreground star from our own galaxy 😃 It is just by line of sight that makes it look like it is connected to the galaxy.
That's right - a satellite trail 😃
Have you had a read of this thread ? http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh 😃
It is not unusual for there to be areas of intense star formation at the end of bars - this is an excellent example 😃
It is an #artifact - something went wrong with the imaging and this is the result 😃
I thinks the 2 stars are unrelated to each other 😃
It looks like 3 foreground star to me 😃
Looks like a overlap of two galaxies 😃 We have the elliptical at the centre and a much more distant galaxy on the right.
Wow - awesome nebula!
This thread is a nice summary of the different types of artifacts: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
@planteryscience - that is not the object we have to classify 😃 The central object looks like a star/s to me 😃
I would go with 2 armed loose spiral. The other blobs are foreground stars overlapping the galaxy.
They are all foreground stars 😃
or a flyby- that would explain the starbursts and distortion in the lower galaxy.
Looks like we have interaction between the 2 galaxies - very early stage merger 😃
One 😃 The orange blob at the bottom is a foreground star.
nice one 😃 #boxy_bulge #x_bulge
Looks more like a spiral arm 😃 Galaxies of this size do not have the mass too cause strong gravitational lensing 😃 But keep looking!
The tiny smudge on the right of the galaxy? I would go for satellite galaxy 😃 Gravitationly bound, so merger would not be far off!
They certainly look disturbed - fly by perhaps?
Lol - looks like they are interacting, Early stage merger perhaps? 😃
Very fuzzy - but looking at the blue color in the top galaxy, suggests star formation - so I would go with yes 😃
#cropped image
ä¸€ä¸ªæ´»è·ƒæ˜Ÿç³»æ ¸çš„è¿¹è±¡ - æ¤åœ†æ˜Ÿç³»ã€‚ -thank you Google 😃
That is a foreground star - it looks like we had imaging problems, so it looks a bit odd.
#irregular #starforming
#boxy_bulge #dustlane #edge_on #x_bulge
Read below 😃
A satellite trail 😃 http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
The resolution is really bad,so we would not be able to tell.
The dot is an artifact - the core of the galaxy is quite bright, so it was over exposed.
This image is quite fuzzy, but the object to the bottom left is a foreground star, so no merger 😃
You would be correct - no signs of interaction, so a chance alignment 😃
They are all foreground stars from our own galaxy 😃
The bright object on the right? That is a foreground star from our own galaxy 😃 same as the orange dot overlapping the galaxy.
Not an exploding star 😃 Something went wrong with the imaging, and a foreground star turned into this lovely artifact.
No, I am thinking it could be a very fuzzy foreground star in front of the galaxy.
Yes, it is an error 😃 It looks like the telescope moved when the green filter image was taken. Sorry! It happens from time to time 😃
Hi @Andrewgalaxy - always remember to only classify the object at the center 😃
There was no film left in the camera 😃 It is the end of particular stripe.
Artifacts caused by a bright foreground star just off screen to the left 😃
Answer below 😃
Foreground stars from our own galaxy 😃 More info here:
http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
and you would be correct! 😃
Foreground stars from our own galaxy 😃 Looks like something went a bit wrong with the green filter, but a really nice star cluster
In this case it look like a foreground star 😃 and SkyServer confirms it 😃
Answer is in the comments previously left below 😃
Satellite Trail 😃 Have you read the comments below? Your question might be answered already 😃
Diffraction spikes from a star off screen. Have you read this: http://tinyurl.com/GZartifacts- it will answer a lot of your questions 😃
I see what you mean 😃 Instead of being totally smooth, we have some spiral features - very fuzzy, but certainly features.
You are only looking at the object at the center 😃
Satellite trails 😃 Have a read of this thread: http://tinyurl.com/GZartifacts
They are artifacts 😃 http://tinyurl.com/GZartifacts
No all galaxies have cores / hubs at the center 😃 This looks like a dwarf galaxy.
The pink middle is an artifact - as this is a foreground star, the brightness has caused over saturation,hence the artifact.
No merger - this is a star 😃
@maxrebo101 - you are right, no bulge! The clumps are area of dense star formation.
@dagueerrotype - Yes! Always classify the object at the center, Disregard all other objects 😃
Yes 😃 It is an #irregular galaxy with #starbursts (areas of intense star formation) - nice!
Difficult to tell, my gut instinct says artifact.
I would say that looks like a #merger 😃 Nice interaction!
I would go with a late stage merger, the second core could be the object at 11, embedded in the central galaxy.
This is an artifact - sorry! Something went very wrong with the imaging / processing 😦
I think we have 2 foreground stars overlapping a edge on galaxy. The stars would account for the double bulge 😃 Anyone else?
I am also seeing a faint spiral features - nice catch!
An #irregular galaxy with a slight #bar - awesome 😃
All look like local stars, have you tried looking at the SkyServer image? Looks like we might be in the middle of a star cluster 😃
possible #polar_ring? not as clear cut as other examples, but still worth a tag.
The blue object is a star. I am more impressed by the #edge_on galaxy with a #dustlane and a somewhat #boxy #bulge at the center 😃
More info here: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
It is a foreground star from our own galaxy. The brightness causes all of these weird artifacts 😃
I would go with multiple galaxy / star overlap. It is possible from looking at the tidal debris there is also a merger in the mix.
Foreground star from our own galaxy, over saturation causes the odd artifacts.
Only classify the object at the center - Thanks! 😃
The blue clumps in the arms are areas of intense star formation. I would go with more than 2 arms, but definitely #barred
Remember only to classify the object at the center 😃 As yes, it is possible that the galaxies at the center are merging.
Actually two elliptical galaxies 😃
Close to the central galaxy?
They three bright objects are foreground stars from our own galaxy. I am sure it will not be too long until you find your first merger 😃
Not seeing much interaction between the two - more likely an overlap, or a flyby.
A nebula - awesome! 😃 If you look at the comments below you will find a link to the zoomed out image.
Difficult to say, the image is very fuzzy. There does appear to be faint signs of interaction between the 2 orange ellipticals. No Spectra.
A bright foreground star just off screen to the left 😃 We have some diffraction spikes and arcs radiating from it.
I would agree with you #barred #spiral 😃
It is a foreground star 😃 Remember to only classify the object in the center - in this case the tiny orange blob (star? )
They all look like foreground stars 😃
A satellite trail 😃 More info in this thread: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
Artifacts 😃 When the image in the green filter was taken, the tracking was not working correctly. The green streaks are foreground stars.
I would go with 5 separate stars - you would be amazed of the shapes that come about, through sheer chance alignment 😃
I do not think it is a merger - there is no interaction between the galaxies. Nice #overlap 😃
Not a nebula - a foreground star from our own galaxy. The weird blue colour and shape are down to oversaturation 😃 More comments below...
Looks like an asteroid, but when the image was stacked the red filter was slightly misaligned.
You are correct - Star 😃
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=148.42666248&dec=55.75879656 and click on 'Get Image' to see the star 😃
That is a foreground star off screen to the right 😃 You can see the diffractions spikes.
Just to add - only ever classify the object at the center - Thanks! 😃
The central galaxy certainly has spiral features, and a barely their hub 😃 The bright object is a foreground star from our own galaxy.
Wow, that is a stunning one! #IC_2098
It looks like an artifact - you can see similar discolouration in the foreground stars. Imaging / stacking error.
No dust lane here 😃 An awesome #barred #2_arm #spiral
I would go with merging / interacting galaxies - no lensing here 😃
Wow - look at that interaction! #NGC_5258 #NGC_5257
Satellites move really quickly, so they only get captured in a single filter
It is a satellite trail 😃
#overlap
I am not so sure...I will have to have a closer look, but it is some what odd.
Not a nebula - a galaxy (or two) 😃
...also no interaction btwn the 2 galaxies, so we can exclude that the star formation in the smaller galaxy is triggered by merging.
I would go with #overlap - just looking at the colour of the galaxies suggests the central galaxy is a lot further away...
I would go with stars, but the alignment is somewhat uncanny.
Not a merger or a black hole 😃 Loads of star formation / star bursts
They are both foreground stars from our own galaxy 😃
That is a stunning one!
@lostlens: also to quote NED - "Interacting pair with NGC 4676A at 0.6 arcmin." #merger
The black dot is an artifact - the rest of the galaxy is awesome! It is a well documented polar ring galaxy 😃
Not a edge-on galaxy or a ring. As you said it is very fuzzy, so that makes it difficult to classify. Also displays spiral features...
It could refer to a cluster of stars, or a cluster of galaxies. Groups or pairing of a particular object.
The red colour is caused by a bright foreground star off screen. It is difficult to tell if we have a galaxy at the center.
A satellite trail 😃 They move so fast, they only get captured in a single filter.
In this case I would say no, there is a hub and a spiral pattern. Dwarf galaies tend to be very non-de script.
they are artefacts caused by a bright star off screen
are you referring to the dark line just to the lower right of the core / hub?
We only have 1 redshift and it suggests star formation, We do know that starbursts can be triggered with a merger. I would go with #merger
Hi @lobeck - it does look like we have 2 cores in the central galaxy, but I will need a closer look... galaxy upper left looks unconnected
#UGC04434 Mentioned in "KISO survey for ultraviolet-excess galaxies" (see NED for more details)
Looks like a dwarf galaxy. Another possibility is a low surface brightness (LSB) galaxy
No ring, looks like a very loose spiral or edge on.
You can't fix an image after it is taken 😃 You can enhance it, tweak it, but if it is corrupted there is nothing you can do about it.
??? please explain @0796441272
Hmmmm, it could be, as there does appear to be a galaxy off screen, but there is also a lot of background noise, and also no spectra.
The image is very fuzzy, so it could also be very tightly wound spiral arms 😃
That's a stunning galaxy! Possible inner and outer rings - nice indeed 😃
It does look a bit disturbed, but as the image is so fuzzy, it is difficult to say for sure!
No spectra, so we would not be able to say for sure. In the meantime nice #barred #ring galaxy 😃
Tidal tails 😃 Nice interacting galaxies!
It is only by line of sight that they look so close together 😃
At the center we have an edge on galaxy, to the left a foreground star 😃
Something went wrong with the imaging, causing these artifacts.
#elliptical #smooth
No, that is in fact a nice example of a #edge_on galaxy 😃
And you would be wrong 😃 It is in fact a galaxy...
No - a foreground star from our own galaxy the milky way.
I would say that they are more likely gravitationally bound than merging. With mergers we would see interaction between the galaxies 😃
Looking at SkyServer and NED I would go with a cluster of galaxies - more impressive if you zoom out 😃
That appears to be the 'z magnitude of the galaxies, not the z redshift (they are not the same thing). Let me have a look around 😃
I would say single object - the colour plates are misaligned. If you have a look on SkyServer it is happening to all objects in the field.
I am not so sure they are merging - perhaps gravitationally bound?
Always classify the object in the center 😃 In this case a foreground star. The black blob in the lower galaxy is a artifact.
There is discolouration in the dr8 image, where we would expect to see the counter image...
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=183.03690026&dec=13.79253341
I am somewhat sceptical #no_lens . If we look at the DR8 image, we can see a similar 'arc' extending in the opposite direction. #curious.
That is a foreground star 😃 Remember to only classify the object at the center. Stunning #bar
Actually looking at it closer it is even more confusing...Scientist?
That is odd. Comet? No. most likely overlap.
WOW, that is a stunner! #barred #spiral
I would go with #spiral 😃
I do not think it is a post-merge,but it is some what odd - looks like a bar gone wrong. Will try to get second opinion.
#sattelite trail
Looks like stars for me 😃
What axis are you basing that on? and hi @planertryscience 😃
No 😃 3 foreground star from our own galaxy.
😃 Read below ...
snap
Both upper and lower looks like arms, The bright place, looks like a star burst
It is an artefact, caused by a star off screen.
I am going to have a look on SkyServer...have you seen this: http://talk.galaxyzoo.org/#/boards/BGZ0000005/discussions/DGZ0000lv2
And you would be right 😃 Amazing!
...lower and to the left. So we are then left with a 2 armed, loose, spiral galaxy ,with star formation in the arms 😃
Not so strange when you analyse it bit by bit 😃 the blue object at the top is a foreground star. So is the yellow object slightly...
They are all stars- the algorithm sometimes gets confused between foreground stars and fainter galaxies. Read below 😃
I would say yes 😃
Hi @mercuryb 😃 ummmm, why are you expecting them to reach the side? I can only give a accurate answer, if I know the actual question 😃
I am thinking all the object here are stars - fortunately for us computers are not that good at classifying!
Have you had a look at this thread - it is really helpful for newbies 😃 http://tinyurl.com/pbo34r2
They are not galaxies, but rather foreground stars. Look like something went wrong with the imaging of that particular field.
Hi and welcome @lobeck 😃 Follow your instincts! There are no wrong answers. Thinking foreground star in this case.
No visible interaction either,more likely overlap.
It looks like a disturbed edge-on, No redshift, so it is difficult to tell if it is connected with the central galaxy.
I would go with #star, if it were an asteroid we would see more movement, and the 3 filters would be more apparent.
After looking at SkyServer, I would go with a cluster of galaxies. No spectra and not much further info.
No- they look like galaxies. I will have a closer look.
#NGC_7595
A very disturbed galaxy, with foreground stars overlapping it.
That is a foreground star from our own galaxy 😃
@cateye1012 The galaxies are in the process of merging, so the 'veil' are millions of stars that are ripped away in a tidal tail.
We have spiral features in the galaxy,so those would be very fuzzy arms.
They are regions of intense star formation or star bursts 😃
#SHOC_142
For those so inclined: http://arxiv.org/pdf/astro-ph/0404133v2.pdf
NED has it listed as a SHOC (SDSS H II galaxies with Oxygen abundances Catalog) galaxy... looking for more info
That is a odd one! Not a foreground star, starburst perhaps? Trying to work out if it is a single object or 2...
Your first guess was correct! #star 😃
Hi @gbollmann remember to only classify the one at the center 😃 The other one will come up in another image 😃
Foreground star - a processing error 😃
They are satellite trails 😃
I don't think it is disturbed :- ) It looks like we have a plane / satellite trail going directly over the galaxy.
I have taken the opportunity to create the discussion. See Right -->
This is the recents tab and not the discussion board after all 😃 If you would like to argue about this, take it there.
@zutopian with all respect, we have both acknowledged that it is possible, and that it will get look at further. Case closed.
... it is very unlikely we would see lensing of this nature, this visible. I am sure it will get further analysed 😃
And everyone is entitled to their opinions 😃 I would add that even if this is a E7 (or similar) elliptical galaxy...
Jinx 😃
That is not a star - but rather a star burst 😃 Star Bursts are regions of intense star formation. There is are several in this galaxy.
or we have a bar forming at the center? Also some spiral features.
There is a lot of background noise in this image so I would go with artifact
#merger
I am not seeing any lensing, are you referring to the dots around the central galaxy, or the blue smudge at 4?
Only classify the central object 😃 In this case a stunning #edge_on
That is a satellite trail, they move really fast so they only get captured in a single filter.
They are foreground stars, but something went wrong with the imaging
awesome #merger
Amazing #merger
Then again it could be an overlap. Skyserver was no help, but the star to the left has similar characteristics to the top left galaxy.
Without going to SkyServer, I would say no. The colour of the galaxy at 11 indicates it is a lot further away than the centre galaxy.
I think it is the same galaxy, just somewhat irregular. Odd indeed. 😃
WOW! talk about a merger!
I think you are right - foreground star 😃
Definitely a #merger of the two central galaxies. Not so sure about the one on the left.
I would say yes 😃 Nice!
I will have a look, but stunning #bar in the meantime 😃
Looks like a polar ring - I would love to have a scientists opinion 😃
😃
That does not prove anything. Why do you think this is a overlap?
The claim being that this is an overlap... just clarifying.
@lostlens unless you can back up your claim, consider this a final warning.
You should have a look at it on SkyServer - really quite impressive 😃
@lostlens overlap why? 😃
You are right 😃 They are both stars from our own galaxy!
I would say that is a satellite galaxy of the larger central galaxy 😃
Perhaps you should start a discussion?
@lostlens there is clearly interaction going on, so it is not a overlap. We would love to hear your reasoning as to why it is a overlap 😃
Loads of interaction between 3 galaxies - http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=83.22151822&dec=-7.77571724
Unlikely 😃 More likely the result of a flyby. Will have a closer look on SkyServer...
No lens for me 😃 It looks more like noise
we also have several foreground stars... Hope this helps, and we welcome more questions 😃
I would go with a #barred #spiral. Loose arms with a big bulge 😃 But that is just me - we want your opinion 😃
I am not seeing many signs of interaction - perhaps gravitationally bound rather than merger?
That is a stunner!
I would agree 😃
No spectra 😦 So we would not be able to say for sure, but it does have a well defined bright core, so it is possible 😃
#NGC0575 #UGC01081
Has a lovely #bar as well 😃
No lensing for me. you are referring to the smudge at the bottom of the elliptical galaxy?
Artifacts - something went wrong with the imaging 😦
#stars loads of them 😃
#bar
Hi @nesMC and welcome. What object are you referring too? The blue object @ 8 or the center galaxy?
I would go with star for the object at 9 😃
Hmmm - are you talking about the black specks at 1 and 8 from the centre of the galaxy?
Unfortunately we do not have a spectra on the galaxy, so it would be impossible to say yes or no. Visually I would go with unlikely.
Wow! That is a stunning one 😃
@diamondmc the orange object in the 7 of the larger spiral? That is another galaxy. In this case they are overlapping 😃
#tidal_bridge perhaps?
Slight #bar at the centre #doublering
I am inclined to think overlap 😃 The pink / orange object certainly looks like it is a foreground star - but I had to look more than twice
😃 Also, it will have no apparent spiral pattern - just irregular - hence the name.
.. looking at the colour of these ones, they are orange and fairly conform, therefore a lot older. Hope this helps, and we love questions!
No, irregular galaxies tend to be lower in the chain of galaxy morphology. They are young,blue and irregular in shape...
Snap 😄
Not blue or irregular enough to be a irregular galaxy 😃 I think merger is more likely
The blueish colour distortion in the lower left arm is due to star formation triggered by interaction. As @ElisabethB said - a #merger 😃
Also, what object did you think was being lensed? 😃
Hi @MartinTheK - I am not seeing any spectra associated with this object, therefore no redshift 😃 Do you have a link?
Looks like the computer got confused by the diffraction spike, would of classified it as star/artifact.
That is a satellite trail 😃 More info here: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
I would say we have a foreground star overlapping a much more distant galaxy 😃
I think they are still in the process of merging, nice starbursts in the arms
At the bottom of the image? or the top right of the central galaxy?
The 'arc' is in fact star formation being triggered by the 2 galaxies at the centre merging 😃
It looks like a star / galaxy overlap 😃
I am not seeing any apparent signs of lensing. What object are you referring to? So I can have a closer look.
Looks like we have some dust - nice!
There is clear interaction - #merger for me.
I would of gone with star /artifact. All foreground stars from our own galaxy.
#merger for me. Possible bow waves at 2 on the off centre galaxy?
The orange one? 😃
Hmmm, I would go with edge-on, the splodge at 6'ish is possibly a satellite galaxy? Really difficult to tell.
also appears to have a nice #bar 😃
I would go with merger.
Amazing #merger
Most of the objects are foreground stars. Always remember to only classify the object at the center.
I would say no. Spiral arms tightly wound back on themselves instead.
A satellite 😉
overlap for me.
Diffraction spike from a star off screen 😃
Welcome @animatus 😃 awesome merger!
@Nakedeye2 - not likely 😃
Most likely a foreground star overlapping a much futher galaxy 😃
They are both foreground stars - remember to only classify the object at the center!
I would go with barred spiral - but it is your opinion we really want to know about! 😃
That is a satellite trail 😃 More info here
#NGC_7729
That is a stunning one!
It looks like a proto-spiral. A young spiral galaxy with loads of star formation, that still needs to settle down into a classic spiral.
Artifact - imaging / processing error.
No lensing - a spiral arm 😃
It is a sattelite trail, for more info look Here
That is an artifact, for more info look Here
Artifacts - caused by bad imaging / processing
Satellite trail 😃 They move so fast they only get captured in 1 filter.
I would say they are both foreground stars 😃
Artifacts caused by imaging problems.
Artifacts caused by imaging problems, for more info look Here
Those are spiral arms wrapped around the galaxy. Not unusual for arms to have a different color than the core / hub of the galaxy 😃
You can get gravitationally bound galaxies, but the dynamics is different from those of binary stars.
I wish! 😃 Those are diffraction spikes and arcs around a bright foreground star. The amazing artifacts are caused by over saturation.
It looks like a foreground star from our own galaxy 😃
Something went wrong with the imaging! Look here for more information on the different types of artifacts
The 2 objects on the left are foreground stars, and the object in the center is a distant galaxy!
All stars from our own galaxy - the lovely colors are artifacts caused by saturation.More info here
All the objects in this image have similar artifacts - looks like something went wrong with the imaging!
Looks like a merger, the second galaxy appears to be the white blob at 6.
That's a #nebula! For a clearer view click on link:
http://tinyurl.com/p3zjxyw
No merger for me - the 2 objects to the right are foreground stars!
Remember to only classify the object at the center! In this case the orange elliptical (smooth) galaxy.
That is a satellite trail 😃. More info here
Not so sure of it being an AGN 😃 AGN's are not very common - most likely just a bright galactic core.
That is a foreground star, for more info look Here
No merging - the objects on the left and right are both foreground star, and I am not convinced the object at the center is a galaxy.
The bottom object is a star from our own galaxy - the milky way. A lot closer than the spiral galaxy at the center 😃
The edge on at 7 or the orange dot on the right?
A satellite trail 😃 More info here
wow - that is an odd one! A very disturbed galaxy - sadly no spectra 😦
Something went very wrong with the imaging - look here for more info on artifacts.
That is an artifact, for more info look Here
You are correct! 😃
All stars from our own galaxy - the lovely colors are artifacts caused by saturation.More info here
I would say it is a bit too irregular to be an elliptical, there is also a faint spiral pattern and bar.
I would go with artifact - looking at the SkyServer image, other galaxies / stars in the vicinity have the similar effect.
No lensing for me - 2 blue foreground stars in front of a somewhat disturbed spiral.
No, it is a cluster of galaxies 😃
Only classify the one directly at the center, in this case the orange object. Not entirely convinced it is a galaxy!
I would say we have a foreground star just to the right of the hub of the galaxy.
Yes 😃 Only the one/s directly at the center!
They are foreground stars from our own galaxy 😃
They are foreground stars from our own galaxy. It is just by line of sight that they look part of the distant galaxy.
It is a young galaxy with loads of star formation going on 😃
This is an over exposed star from our own galaxy, for more info look Here
No :- ) it is a cluster of foreground stars from our own galaxy.
The clumps are areas of star formation in the spiral arms.
No 😃 a satellite trail
Lyle?
just different orientation...
No lensing - same as this image from UKIDSS
AGZ0006hsq
Another example of SkyServer being confused - 2 stars overlapping. The UKIDSS survey is over, so I think we are back to old SDSS images.
Thank you 😃 Will look it up more in the morning - bedtime for me!
At the core? or else where in the image?
Although we only have the redshift of left galaxy, Visible interaction is still apparent. Interested to hear why you think differently...
You are right - foreground stars from the milky way 😃
No quasar - elliptical galaxy.
That is a foreground star.
Read comments below... sadly not.
No, no quasar - just a elliptical galaxy. Sorry 😃
If that wasn't flagged as a star, I would of investigated it further. That is a classic cusp arrangement for a GL.
and please not delete your previous comment and repost it 😃 Consider this a warning.
I am sure that there are people that would appreciate knowing 😃
@lostlens - can you please state your reasons as to why this is an overlap and not a merger? Thank you 😃
The bright objects at the top are foreground stars 😃 Can't see any signs of merging with regards to the central galaxy itself.
The bright multi - coloured object is a foreground star 😃 More info here
No gravitational lensing - they are both stars 😃
Difficult to tell what object is at the center as it has been cropped, but you are right it is that object. Looks like a foreground star...
#no_lens - That is an artifact, for more info look Here 😃
It is a foreground star 😃 See the older comments below yours 😃
collisional ring galaxy?
Almost looks like a #hoag object if you take the angle into account. edit: would of expected it to be less disturbed if that was the case.
No merger - something went very wrong with the filters!
Yes - it is most certainly a galaxy 😃
It is not real - it is a artifact that was generated during imaging or processing.More info here
That blue ring / dark spot at the center is an artifact, caused by the brightness of the galaxy.
It is not real - it is a artifact that was generated during imaging or processing.More info here
Nice #boxy_bulge #X_bulge
That is a #bar and it only looks a bit odd because of the angle we are viewing the galaxy 😃
#barred #2_armed #spiral
A mixture of foreground stars and clumps of star formation in the spiral arms of the galaxy.
The bright blue object is a foreground star from our own galaxy - The Milky Way,more info Here 😃
The UKIDSS infrared images are more difficult to classify, but just try your best 😃 I would say this one has a faint spiral pattern.
It is a sattelite trail - for more info look Here
That is a foreground star from our own galaxy - for more info look Here
It is background noise in the image 😃
Look in the comments below 😃
A foreground star from our own galaxy 😃 More info here
Lol - I knew it reminded me of something!
The bright spot is a foreground star from our own galaxy. Is the gap you are refering too at the bottom? If so it is an illusion 😃
There is no such thing as right or wrong - we want to know how you interpreted the object 😃 As for arms, difficult to tell - v.fuzzy!
That is an artifact - it was caused by a imaging / processing error - Sorry!
No worries - we are here to help 😃
...- it is too close and too light weight, to cause that type of gravitational lensing.
I would go with overlap. I would expect more curvature in a lensed galaxy. Another problem is the lens galaxy itself...
The other bulges are areas of intense star formation, this looks like quite a young galaxy (relatively speaking 😉 )
The green / blue cloud is an artifact 😃 They are not real - you can look Here for more info 😃
That is an artifact - it could be particle strike or a imaging error. Whatever it is it is not real 😃
I am positive it is a galaxy - or four!
They are both foreground stars 😃 It is only by line of sight they look like they are connected. The pixelation is a artifact.
Sort of 😃 Bright objects cause some interesting colours in the UKIDSS infrared images. In this case the magenta core happens to be a #QSO
Yes, that certainly has features of a spiral galaxy 😃
Yes 😃 A lovely one at that!
No, it is a galaxy 😃 It just looks a bit odd as this is an infrared image (see the label UKIDSS in the bottom right of the image?)
Yes, an #artifact !
You can if you want too, but it is not necessary 😃
No lensing - Sorry! That a spiral arm 😃 #no_lens
That is an artifact. Only visible in 1 filter, and not visible on the optical image.
The bright blue object is a foreground star from our own galaxy - The Milky Way 😄 More info Here
Looking at the interaction between the two I would say - #merger . In the optical image the smaller galaxy has a odd color. Sadly no spectra
No lensing - Sorry! It is a artifact caused by the brightness of the galactic core. It is quite common in the UKIDSS infrared images.
There certainly looks to be interaction between the two, and the blue colour in the arms indicates dense star formation. A likely #merger
Just classify the one in the center - thanks 😃
Some of the red dots are much more distant galaxies, others are foreground star. Difficult to tell in these infrared images.
Hi @Lozang and welcome - remember it is the object at the center we are classifying 😃 In this case it is a smooth elliptical galaxy.
Here is optical image: http://tinyurl.com/ldbj9qv Looks like we have a lovely inner #ring 😃
#Barred #spiral with the arms possibly settling into a ring. Noticeable bulge - will be interesting to see the optical image...
What a gorgeous #merger and looking at the red shift these galaxies are quite close - relatively speaking of course 😃
Ooops - In my previous comment in this thread I meant to say it is not an overlap - it is most likely star formation. Sorry @maglis 😃
They are foreground stars from our own galaxy 😃
I would of classified it as a artifact! Something went very wrong with the imaging / processing 😃
3/3... with these acronyms - they are basically the same thing! Think I will have to do more digging, once I have finished my dinner!
2/3.. I would say no. It is also flagged as QSO_Reject. Then looking on SIMBAD it has been flagged as an AGN. Don't get confused with..
1/3.. This is a confusing one! It has a really bright core which would suggest it is likely, but looking at the Spectra found on Skyserver..
#AGN #Seyfert_1
#AGN #Seyfert_2
#barred #spiral #seyfert_1
I would go with #merger we have clear interaction btwn the central galaxy and the smaller companion. The galaxy at 11 also looks connected.
This in a infrared image so they are a bit difficult to classify 😃 That arc is a spiral arm, but even in the SDSS image it is fuzzy.
The UKIDSS images are sometimes difficult to classify - I would go with spiral / obvious bulge
#merger
That doesn't look like a merger to me - sorry! Even looking at the optical image I am more inclined to go with star formation.
Wow - that object is almost microscopic! There is no way to tell if that is a very faint foreground star or distant galaxy!
#merger for me. Clear signs of interaction with starburst activity. Distended arm to the right.
A very tight spiral? possibly SBb?
As for the process of star formation, you can start here: http://en.wikipedia.org/wiki/Star_formation
They are both foreground stars from our own galaxy - The milky way.
A galaxy with a very bright core 😃
The blue objects are all foreground stars from our own galaxy. #No_merging.
Always classify the object at the center! In this case the smooth galaxy.
The colours are not real, something went wrong with the imaging - sorry!
They are foreground stars from our galaxy. In this case it is a star cluster. Try having a look on SkyServer - very impressive!
I would go with merger. 2 of the objects have a similar redshift and there are signs of interaction. Hope this helps!
A very disturbed galaxy in the process of merging with another galaxy. Here is the optical image: http://tinyurl.com/lcupvoj
2/2.. will have an intense blue colour. I have heard them being referred to as starbursts / starformation regions and nurseries 😃
1/2.. You can tell from the spectra, or in optical images, looking at the colour of the galaxy. Young stars are hot and blue, and areas...
The co-ords are the same but it appears that both NED and SIMBAD are also referencing a foreground star at a similar location. Line of sight
It is a satellite trail 😃
Looking at the optical image it looks like a very disturbed spiral galaxy, possible merger.
A foreground star overlapping a much more distant galaxy 😃
It is an artifact caused by imaging / processing.
It is an artifact.
The red object is also a galaxy, according to NED it is a 'red compact'. It also has a interesting spectra 😃
The streak is a diffraction spike,
and the green circle is a artifact 😃
The forum is pretty much dead. Only active threads are the game ones - sad, but true.
Hi All 😃 it is not necessary to comment / hash tag everything we find on SkyServer - we can already cross reference the data.
The blue object at the bottom is a foreground star from our own galaxy 😃
It's a dust lane 😃
What a lovely galaxy cluster! More apparent in the SkyServer image.
#merger
No lensing - just 2 interacting galaxies!
The answer is in all the comments below 😃
Stars 😃
Hi @ntac - the bright blue object is a star from our own galaxy. Hope this helps!
An imaging / processing error - sorry 😦
The blue bits? It is an artifact, but what causes this particular type I do not know.
here is your galaxy in the optical: http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=194.48794084&dec=5.42073171
This is an infrared image so the colour scale is different. Red means bright.
Yes 😃 It is a satellite trail.
@lostlens - please stop deleting your previous comments. There is clear interaction between the 2 galaxies, with some nice tidal streams.
#merger
The galaxy looks somewhat disturbed, but that is not down to the bulge. Dust lanes is a likely cause.
It is an area of star formation or a star burst within a spiral galaxy. In this case it is part of a larger object, so classify the galaxy.
#merge
excellent!
It is your classification we are interested in 😃 but barred spiral looks good 😃
#merge
Yes 😃
English please 😃 We can't support all languages and I guess you do not speak Afrikaans?
@lostlens why do you think it is a overlap and not a merger?
So their is no confusion this is a optical image (SDSS) not a infrared image (UKIDSS), Makes a big difference.
Yes 😃 and it has triggered off loads of star formation in the left galaxy. That is why it has a blue colour - young stars are blue.
Far from it! This is an infrared image, so it has a different colour scale. Have you had a look at the optical image on SkyServer?
The stars would of masked out the much more distant galaxies. Still an amazing star cluster!
I do not see any signs of lensing. Looking at the optical image I would say dust in an oblique spiral galaxy.
What a beauty! Amazing #spiral with loads of star formation
Yes 😃 both of the blue / green objects away from the galaxy are foreground stars.
This is a spiral galaxy so it is less dense in the arms at the edge of the galaxy.
And you would be correct 😄
That is a satellite trail 😃 Not blue shift, but rather different filters during its transit.
3/3.. the bulge. These are rare, and it would have to be a big spiral. This one is a bit of a lightweight 😃
2/3.. have a smaller mass than older ellipticals. Spirals can cause lensing, but they tend to be edge on, with the lens focused around...
1/3.. I am also going to add my vote of #no_lens . Firstly it is the mass of the galaxy that causes lensing. As Els mentioned spirals..
The redshift is quite similar, but apart from the proximity, there is not much interaction. Gravitationally bound rather than merging?
... also, the 3 objects have similar colouring in the optical image. If this was a lensed quasar the colour difference would be noticible
No lensing for me 😃 More like a cluster. The galaxy at the centre would not have enough mass to cause lensing of that magnitude...
Yup - stars do amazing things don't they 😄
No merging or collision - possible gravitational #lens. Very nice.
They are all foreground star from our own galaxy - The Milky Way.
It is a foreground star from our own galaxy.
Here is the same galaxy in the optical: http://tinyurl.com/nep857a
That is a galaxy! This is an infrared image, so if the galaxy has a bright core there can be some color distortion.
That is a foreground star from our own galaxy, they are so bright they over saturate the camera.
Okay 😃 It is just confusing to newbies, they then get the impression the whole image needs to be classified.
I would go with irregular galaxy. Looking at the optical image there is loads of star formation going on.
It is definitely showing sign of being a spiral galaxy 😃 The UKIDSS images are a bit more difficult as the features are fainter.
Remember to only classify the object at the center!
That red line is a satellite trail - more info Here
From this image alone I would say it is showing signs of interaction. Possible fly by?
I would also go with #barred #spiral 😃
Yes 😃 a #spiral galaxy - It looks more impressive in the SkyServer image.
They are both foreground stars - this is a infrared image so the colour scale is different.
2/2... they tend to over emphasize the brightness of the core. Also to make the classification you would need spectra. This galaxy has none.
1/2... @MikeOborn - just because a galaxy has a bright core, it does not mean it has an AGN 😃 These UKIDSS images can be misleading as ..
I would also go with bulgeless 😃
The object at the centre is a galaxy. I am inclined to think the other 2 objects are foreground stars.
The bright object is a foreground star from our own galaxy - The Milky Way. Have you read this
Another possibility is that it is a late stage merger. Pity we don't have spectra, as SkyServer has this flagged as 2 galaxies.
The bright object is a foreground star from our own galaxy. The object you needed to classify is the tiny orange object at the center.
It is a processing / imaging error, if you look at SkyServer you can see it is a nice galaxy cluster.
No 😃 It just looks that way due to line of sight.
That is an optical artifact 😃 More info look Here
It is an artifact caused by the brightness of the core of the galaxy. The infrared images are very sensitive, and oversaturation is common.
2/2.. objects not at the center will have a chance to be classified in other images.So all objects get a chance. Hope this helps 😃
1/2.. Only classify the object at the center of the image, the only exception is if it is interacting / merging with another galaxy 😃
It is a spiral galaxy with lots of star formation 😃 Although looking at the optical image there is a weird 'bulge' in one of the arms ?
I would also agree #merger 😄
I would go with #merger 😃
No lensing - Sorry 😦 It is just an optical artifact around a foreground star.
Those are diffraction spikes - usually caused by the wires that hold up the secondary mirror in the telescope.
In the top left? That is a foreground star from our own galaxy.
I am also concerned that there are too many other similar coloured objects close to the galaxy, for it to be lensing.
No planets 😃 That is a foreground star from our own galaxy.
Yes 😃 but remember to only classify the object at the center.
Always classify the single galaxy right at the center - the other objects you can ignore.
Galaxy on the left, foreground star on the right.
Um, why? Just a galaxy and a amazing foreground star 😃
2/2... If you follow the hyperlink posted by @lostlens below you will see the optical image.
1/2...It is an infrared image so only the brightest objects are visible, that is why the galaxy you have to classify is so faint.
Sorry - no ring galaxy! It is a foreground star from our own galaxy 😃
This is a UKIDSS image, so only the brightest arms are visible - looks quite different in the optical!
It is a very disturbed spiral galaxy - could be a result of a fly by or merger.
The dots are not real - it is artifacts that were generated during imaging or processing.More info here
I am not seeing any signs of merging, and the bright blue object in the bottom left is a foreground star 😃
That is a foreground star from our own galaxy - the strange colour are caused by over saturation. Info
No lensing 😃 and the green line is a satellite trail - look Here for more details.
The green / pink object is a foreground star from our own galaxy 😃
The green dots are a common #srtifact from the UKIDSS images.
No lensing 😃 The 2 green circles are artifacts. More info Here
pleasure 😃
Hi @benhoofe1 😃 Which object are you referring to?
I would also go with #merger
Not unusual to have a large bulge at the center of the galaxy 😃 Although this galaxy does seem a bit disturbed. Possible interaction?
It is a #merger between multiple galaxies, loads of interaction, and stunning dustlanes 😃
This is a difficult one to classify as it is the pale blob not the orange blob that you need to classify - For me star/artifact 😃
The green dot could be an artifact as it is only visible in the 'r band. The white / purple blob could be a foreground star.
Other ideas?
Very similar redshift, and we can see interaction - so I would say #merger 😃
I would go with a two armed spiral - it is more prominent if you look at the SkyServer image.
Yes, the green dots are an artifact 😃
It is a artifact that was generated during imaging or processing. More info here
It is not real - it is a artifact that was generated during imaging or processing.More info here
#no_lensing for me - more likely to be star formation 😃
That trail is a diffraction spike from a star - you can see it clearer in the Skyserver image.
Correct 😃 artifact
@Wisi_EU but someone classifying the image would not have access to that data 😉
Wow, indeed 😃
#NGC5033
here is the full image
It is not real - it is a artifact that was generated during imaging or processing.More info here
That is an sattelite trail, for more info look Here
Sorry 😦 no X-shaped bulges - we would only see them in edge-on galaxies, this is clearly an S0 elliptical.
That is an artifact, for more info look Here
Not entirely convinced it is an AGN, possible merger with star formation perhaps?
It is not real - it is a artifact that was generated during imaging or processing.More info here
The green dots are artifacts 😃
It is a fuzzy #barred #spiral
@Jonas.dreesen do you have a question? 😃
Here is the optical image and the spectra. It look like a normal red elliptical galaxy - no AGN 😃
Hmmm - I am not seeing anything that suggests this is an AGN. I am interested to know why you think it is one? 😃
Hello and welcome @VjMilo - do you have a question? 😃
Certainly looks like it in the optical image here
No, I do not see anything that would suggest this was a merger, but it is a lovely #barred #multi_armed #spiral 😃
Not a nebula - a galaxy 😃 Here is the optical image of the same galaxy (slightly rotated/flipped).
That is because the images on SkyServer are optical images, this is a infrared image from the UKIDSS survey 😃
All stars from our own galaxy - the lovely colors are artifacts caused by saturation.
No supernovas 😃 Foreground star from our own galaxy, for more info look Here
Sadly not 😃 It is not unusual for a galaxy to have a bright core, without having an AGN. Also, spectra says no.
Similarly, the spectra does not suggest an AGN.
Looking at the spectra I would day no AGN.
#satellite trail, they tend to look like rainbows in the UKIDSS images.
No lensing - that is an artifact - for more info look Here
Looking at the optical image, looks like a young #star_forming galaxy - somewhat #irregular
#boxy #edge_on galaxy
The galaxy at the center is really quite interesting... #barred #ring #agn_possible
Not a planet 😃 Just a diffraction arc caused by a bright star off screen.
It is not unusual to have more than 1 galaxy in a image, but only classify the one at the center.
I would say yes 😃 The other three multi-coloured objects are foreground stars.
The green ring is an artifact - for more info look Here
#barrred #spiral - with the UKIDSS images the features of the galaxies are a bit harder to see. Always classify what you think you see 😃
... looking at the notes in NED has been previously analysed by astronomers as a high HII region.
This is an infrared image from UKIDSS so it will look a bit different from the optical - loads of #star_formation, quite unusual...
No gravitational lensing 😃 I would say merger, or gravitationally bound galaxies.
See answer in the comments below 😃
It is a foreground star from our own galaxy - so you were right! 😃
Very faint galaxy with #spiral features. To the right a star. Always remember to only classify the object at the center 😃
The green object is a artifact that was generated during imaging or processing.Read this for more info.
It is a galaxy - this is one of the UKIDSS infrared images so the colour can be a bit weird. The pink is caused by a really bright core.
That cloud is in fact another galaxy #UGC06970 - looks more impressive in the optical.
Both are stars from our own galaxy - the lovely colors are artifacts caused by saturation, more info Here
The central object is a galaxy and the object on the right a foreground star. No nebula - sorry!
lol 😄
It is a galaxy - just viewed in the infrared. Here is the optical image of the same galaxy.
No, I don't think so as. I am not seeing another object it could be interacting with.
Most certainly a loose spiral, a bit more difficult to tell if it is barred. I would go with unlikely.
@jonas.dreesen - Hi and welcome 😃 What object are you referring to?
It is a artifact that was generated during imaging or processing.Read this for more info.
All stars from our own galaxy - the lovely colors are artifact caused by saturation.
The green dots are artifacts - you can read more about them Here
That is a foreground star - this is a infrared image so they tend to look a bit strange 😃
Always classify what you see 😃
Being able to look at the SkyServer image is a bonus, but not necessary 😃 I would say #merger
Wow, amazing #tidal_trails
We certainly have a #bar , this being a UKIDSS image I will go with #spiral not ring.
I would go with edge on 😃
That is interesting! Clearly visible in 'i and 'z filters, not entirely convinced, but should be looked at. #lens
This one is definitely a galaxy 😃
First off ignore the star, we are only classifying the object at the center - a #barred #multi-armed #spiral
I think it is safe to tag them as #merging 😃
They are all next to each other - here is the optical image: http://tinyurl.com/o3l58q5 (you may need to click 'get Image' on the left)
No! An amazing #edge-on galaxy!
Nice! It is a galaxy, but the reason for the strange colour is that it is harbouring a #QSO - a quasar for us laymen 😃
That a star - but yes, they do create amazing artifacts 😃
I don't think it is an artifact - perhaps another galaxy?
No lensing for me 😃 This is a infrared image, and they do tend to create some spectacular artifacts
#merger and #agn - nice!
I really wish they wouldn't do that - makes things hard for us astronomers 😉
That does look quite exciting - the resolution is not so good, but I will also add my #lens tag
Sadly not 😦 It would be awesome if it was! The brightest object on the left is a star. The other objects look like satellite galaxies.
#artifact
The blue and green dots are indeed artifacts 😃
no lensing #barred galaxy
No lensing - This is a infrared image, so the purple discoloration is a artifact #starformation #spiral
They are both artifacts.
No merge - just intense star formation. This is a infrared image, so only IV sources will show up.
This is an infrared image... do you mean optical?
The blue object at the top of the screen is a foreground star from our own galaxy.
I would go with a loose 2-armed spiral 😃
#star This is a foreground star from our own galaxy
These are foreground star from our own galaxy.
The green dots are artifacts, not too sure what went wrong.
The blue / green object is not real - it is a artifact that was generated during imaging or processing. Hope this helps 😃
Well it is a star from our own galaxy, so it would appear larger than a galaxy millions of light years away 😃
They are all local stars from our own galaxy
An artifact...
Sadly not. The ring is an artifact, and the galaxy is a lovely #edge_on
That is a foreground star from our own galaxy - the Milky Way 😃 The discolouration is due to over saturation.
That is a foreground star from our own galaxy. The strange color is due to over saturation 😃
...satellite galaxy perhaps? No redshift on either of the galaxies.
On the left we have a star, so your are correct! I am still undecided about the galaxy on the right, there could be some interaction...
In the UKIDSS infrared images it indicates a very bright area, this could mean an AGN, but we would need to look at the spectra.
Not seeing much interaction, so personally i would go with #overlap. They could be gravitationally bound, but without redshift, can't tell.
The blue / green object is not real - it is a artifact that was generated during imaging or processing.
No, it is a galaxy - According to NED - a ZOAG (Zone of Avoidance) Galaxy. That just means it is 'behind' the milky way.
Here is the optical image - really nice! http://tinyurl.com/AGZ000703x
(you might need to click on 'Get Image, on the left)
Looking at the redshift and NED - yes, it is a cluster 😃
I would personally say yes. Nice!
It is a disturbed #spiral galaxy. Looking at the spectra, we have a lot of star formation going on 😃
Sadly not! The brighter object is a foreground star overlapping a galaxy. Hope this helps 😃
The central galaxy or the star to the right?
It is a satellite trail - look here for more info: http://tinyurl.com/GZartifacts
That is a foreground star from our own galaxy - The Milky Way.
Those are all foreground #stars - the 'jet' is a diffraction spike (another kind of artifact)
That is an artifact 😃 Have a look here for more info http://tinyurl.com/GZartifacts
That's most definitely an artifact 😄
I would go with merger
A very disturbed galaxy with star formation, possible later stage merger. I think the red dots are foreground stars.
Looking at the spectra, I think we can discount AGN.
No, irregulars are a lot more disturbed and when viewed in the optical SDSS images they are blue. This is one of the more difficult ones...
I would go with #merger
It could be a #merger or #overlap - difficult to tell without the redshifts of both galaxies.
What a gorgeous #spiral
The different coloured objects are all foreground stars from our own galaxy 😃
That would be my choice as well 😃
It is a #spiral , but in my opinion it is not disturbed.
They both have the same redshift, so I would say yes 😃
It looks like it :- )
Only in the SDSS images... It will be different for each survey 😃
That is an artifact - the brightness of the hub of the galaxy causes over saturation in the camera.
No voorwerpjes - as this is a SDSS images they would be a vivid bright blue 😃 I do agree with #star_formation
I do not think they are colliding 😃 But interesting... chance alignment? or something else?
It looks like a star cluster. SkyServer has it incorrectly flagged as a galaxy.
That is a new one.
We really need a gallery for them!
The red object? No, it is a foreground star from our own galaxy 😃 We also have a gorgeous elliptical galaxy at the center.
A foreground star from our own galaxy. Awesome 😃
The two objects bottom left are foreground stars. At the center we have a lovely fuzzy #barred #spiral 😃
These infrared images can be a bit deceiving - that is in fact a spiral arm. Have you tried looking at the SkyServer image? Lot clearer!
An artifact- sometimes the brightness of the hub of the galaxy causes some interesting optical artifacts in these infrared images 😃
That is an artifact 😃 It is not real - look here for more info: http://tinyurl.com/GZartifacts
I would go with your first choice - optical artifacts 😃
Looking at the optical image, I would say yes. Nice!
We have a foreground star from our own galaxy in the top right. Happy Hunting!
No merger for me - we have a foreground star to the right 😃
This is a #spiral galaxy
It's a foreground star 😃
We do have areas of star-formation in an irregular galaxy, but I think the 2 big blue objects at the bottom are foreground stars.
These are infrared images, so objects will look different from there optical counterparts.
The red object is an artifact, it is not visible in the optical image.
The blue objects are indeed stars from our own galaxy 😃
That red circle is an optical artifact - have a read here for more info:
http://tinyurl.com/GZartifacts
...terminology - It can be confusing for new users 😃
@MikeOborn - on GZ we use the word 'Smooth' to classify an elliptical galaxy. This galaxy is clearly a spiral - please be careful of your...
No 😃 Not a black hole - looks like we had some major imaging issues. Everything is accounted for on the optical image 😃
The 3 bright objects are in fact foreground stars from our own galaxy 😃
It is indeed an artifact - it is not visible in the optical image, so it is unique to the infrared survey.
That green blob is an artifact 😃 Rad this thread for more info http://tinyurl.com/GZartifacts
Yes, it is still a galaxy! Possibly a dwarf galaxy? but it does look somewhat more robust in the optical image.
A galaxy - this is a infrared image, so not everything you would usually see in a optical image is visible.
I don't think so as it is not visible in the optical. Thinking artifact.
Another type of artifact - a diffraction arc.
No, that tiny image at the center is the one you have to classify. In this case somewhat difficult... 😄
Hmm - I am not seeing an AGN in this image. This is in the infrared so we would expect to see some color distortion. Nothing on NED/SIMBAD
I would of classified it as having one, along with a #bar
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=126.98636731&dec=28.27504432
This is an infrared image - so it is not the same as viewing it in the optical 😃 In the optical your galaxy has a pair of fuzzy arms...
That is just an artifact caused by oversaturation.
AGN's are not limited to spiral galaxies, a famous example is M87, an elliptical galaxy.
That blue coloured object is a star from our own galaxy 😃
It is two galaxies merging - Stunning!
the yellow objects at the center are both galaxies.
Sadly not - just a star from our own galaxy 😃
Another artifact 😃
Sorry! The black dot is a artifact. It is not visible in the SDSS DR8 image.
The blimp near the galaxy is also not identified on NED, I cant help thinking it is an overlap... intresting.
I would go with #irregular galaxy 😃
The blue object is a star from our galaxy. The rust object is a more distant galaxy 😃
I do not think it is a merger, star burst perhaps?
Look like a awesome #merger 😃
No merger for me 😃
Yes they are 😃
I think #overlap as I do not see much interaction. Color of the smaller galaxy suggest is a lot more distant than the central.
No lensing, but areas of dense star formation. I once read that it is not unusual to have these starbursts at the end of bars...
... will need to find the source for that!
The blue object is a foreground star from our own galaxy 😃 The other objects are unrelated to the star or the galaxy.
A #merger possibly a #triple - looking at the optical image we have loads of star formation going on!
Most definitely a star!
Hi @MikeOborn - a smooth galaxy would have no features or spiral arms. This is a spiral galaxy, with clumps of star formation in the arms.
They are artifacts - look here for more info: http://tinyurl.com/GZartifacts
That is a foreground star from our own galaxy 😃
Yes, it is not unusual to have clumps of star formation within a galaxy.
Yes, the red dot is an artifact.
Could also be a satellite galaxy, or a dense area of star formation.
Another form of a artifact - in this case a diffraction arc caused by a bright star off screen.
SkyServer is not always correct - I would also go with star!
snap 😃
This one is a galaxy, the color distortion at the center is an artifact due to a very bright galactic hub.
Yes it is 😃
I wish 😃 The object at the center is a galaxy. The line intersecting it, is a diffraction spike from a really bright star just off screen.
They are stars from our own galaxy - the Milky Way
Hi and welcome 😃 That bright object is a foreground star from our own galaxy. Really nice #barred #spiral galaxy
I would say it is highly likely - lots of interaction. Here is the optical image: http://tinyurl.com/AGZ00069j7
We have no spectra on the image, but looking at the brightness it is possible. Dense star formation is also possible.
That less bright object is another galaxy - looking at its colour in the SkyServer image, it is quite a lot further than the center galaxy.
It is an artifact caused by the brightness of the core or hub of the galaxy.
Definitely a foreground star - SkyServer is not always correct.
Skyserver has it flagged as one 😃
According to SkyServer they are both galaxies, with similar redshift. #merger
Looks like merging galaxies, so the bright spots you are seeing are dense area of star formation triggered by interaction.
They are optical artifacts 😃 Look here for more info: http://tinyurl.com/GZartifacts
I would say they are merging galaxies 😃 Sadly no redshift, but it is clear that we have interaction between the two
The 2 blue objects are foregrounds stars from our own galaxy. The object in the middle is a elliptical galaxy.
Hi and welcome 😃 That is a star from our own galaxy.
No lensing 😃 it looks like a cluster of galaxies.
It is a galaxy - it looks a bit odd as this is one of the infrared images.
More info on both here: http://tinyurl.com/GZartifacts
At the top of the screen we have a diffraction spike from a bright star off screen. The weird one at the bottom is an artifact.
That red line is a satellite trail 😃 Read this for more info: http://tinyurl.com/GZartifacts
That is a foreground star from our own galaxy 😃
I do not think it is a merger. Looking at the spectra, there is a lot of star formation going on in this galaxy
#disturbed #spiral with star formation. Possible flyby - on SkyServer we have another disturbed galaxy at 3.
The blue object is indeed a star, and I agree with the comments below - there does seem to be interaction going on.
No lensing for me - looking at the optical image the points are different colors - that would not happen with lensed quasars 😃
The multi-coloured object at the top is an artifact 😃
That is a foreground star from our own galaxy 😃
Yes 😃 The bright blue bits are areas of star formation. Nice 😄
I agree - it is a merger. Nice 😃)
no gravitational lensing - a nice #barred #spiral with stars and other artifacts...
Sorry, No. Something went really wrong with the imaging 😦
It is an artifact - still under much debate as to the cause. Happy hunting 😄
A star 😉 It is a diffraction spike. The star is just off screen to the right...
There is a whole thread on Boxy Bulges on the forum: http://www.galaxyzooforum.org/index.php?topic=275643.0
#dustlane ... not so sure about boxy. Boxy bulges tend to have an 'X' embedded in them.
nice #dustlane 😃
Hmmm - definite bar, but personally no ring for me
...or it is just a random alignment.
He sure does get around a lot 😉
@lostlens : having analysed the NED / SkyServer data myself, can you please explain what you mean by 'no kinetics'.
Sadly not! It would be awesome if that were true 😃 In this case the green and blue dots are artifacts.
An overlap between a galaxy and a star.
The blue object in the lower left of the galaxy is a star, it is clearer in the optical image - Happy Hunting 😃
If the redshift was greater, it could be one of PeterD's blue catapillars
At the center? I would go with galaxy.
I am not seeing much interaction between the 3, so #overlap is also a possibility.
Sorry - that is an artifact! No galaxy.
You are right! It is a stunning dustlane 😃
Both blue objects are foreground stars 😃
Yes 😃 and it is stunning! Also - nice #bar
No lensing - the light blue objects are foreground stars. The dark blue spots are artifacts.
That a star from our own galaxy 😃
Interesting question - but totally unconnected with this galaxy 😄
The blue blob is a foreground star from our own galaxy 😄
That is a artifact - have a read of this for more details: http://tinyurl.com/GZartifacts 😄
No lensing 😃 A gorgeous #barred #ring galaxy
They are artifacts - more info here: http://tinyurl.com/GZartifacts
Always classify what you see - it is your opinion that is important! In this case you could of chosen odd -> other 😃
That object is a foreground star from our own galaxy.
The red object is an artifact - more details here: http://tinyurl.com/GZartifacts 😃
It is a foreground star from our own galaxy - have a read of this http://tinyurl.com/GZartifacts
According to SkyServer it is 3 galaxies - but without redshift for all 3 it is difficult to tell if it is a merger. I think #overlap myself
@Rudy87 - what object are you referring to? 😃
That smaller object is a star from our own galaxy. It only looks blue/white as this is an infrared image. If you look on SkyServer it is red
It is a foreground star from our own galaxy - it looks a bit strange as this is an Infrared image
The blue dots and circles are artifacts - look here for more info: http://tinyurl.com/GZartifacts
I would say the pink and yellow object looks like a star. The brightness of star can cause some interesting artifacts 😃
I would say the smaller one is a neighbouring galaxy - possible interaction between the two 😃
They are both galaxies - looking at the interaction between them, I would say possible merger.
Sadly not - the bright blue objects are foreground stars. They look a bit different as this is an Infrared image 😃
I would say yes 😃 nice #bar as well
Looks like the image is a bit #misaligned. When looking at the RA/DEC it is the #edge_on galaxy on the right
Looking at the image as is - I would go with spiral 😃
#greenlatern must be running out of steam - he appears to be fading 😄
Think of it as two galaxies dancing round each other and eventually combining into one galaxy 😃
It is a trail of stars 😃 The two galaxies are merging, so the stars from both are being 'thrown' together and are forming tidal trails
Looking at the Spectra I am not so sure it is an AGN - almost certainly a merger, and that can trigger intense star formation. Scientist?
That is an artifact 😃
I would also go with 2 stars, but I think they are just overlapping and not colliding 😉
You are right - that is a star!
Relatively speaking, and compared to the other galaxies we are classifying, that would be a very close 😃
The golf ball is a foreground star from our own galaxy 😃
The top galaxy look like an #edge_on galaxy. Remember to classify the object at the center! 😃
The green object is an artifact - have a read of this: http://tinyurl.com/GZartifacts
The lower blue object is a foreground star from our own galaxy 😃
That is most definitely a galaxy! I would say an E0 Elliptical 😃
SINBAD also has it listed as having an #AGN
It is a galaxy that has a lot of active star formation going on - that is what is giving it a weird color in this infrared image 😃
I would go with #disturbed #spiral - there may also be hint of a #bar.
The blue object is a foreground star from our own galaxy. It looks a bit strange as this is a Infrared image.
Artifacts -) Have a look here for more info http://tinyurl.com/GZartifacts
It is an artifact - have a look here for more info 😃 http://tinyurl.com/GZartifacts
The big galaxy is #NGC4448, the one that needed to be classified was the tiny one at the center of the image, being somewhat obscured 😃
They are artifacts - there is still some discussion on what causes them.
It is a spiral galaxy #NGC0245 - The blue areas in the arms are starbursts - regions of intense stellar formation,
Those all look like foreground stars (and SkyServer agrees 😉 ) - possibly part of a cluster.
In this example, I would go with smooth 😃
It is an optical artifact - look here for more info http://tinyurl.com/GZartifacts 😃
Looking at the optical image, there are similar objects elsewhere. More distant orange elliptical galaxies perhaps?
The reddish object is an artifact. Looking at the redshift the galaxies are gravitationally bound / merging.
Not quite - it would then no longer be a spiral, and would be classified as lenticular.
Yes 😃
Might be the result of a flyby.
It is also a galaxy - very disturbed due to collision / interaction. Have a read of the discussions on the right...
I would agree with that - chance alignment between galaxy and stars 😃
They are artifacts 😃
I would go with #ring - definitely not a lens.
You are correct - it is a star 😃
Wow - what a stunning #barred #ring #spiral galaxy
I would go with spiral. We also seem to have an #overlap
The blue and green dots are artifacts. The galaxy in the middle looks like an E7 elliptical galaxy.
No supernova - just a star 😃
No 😃 The blue object at the top is a star - infrared images such as this one are sometimes difficult to classify 😃
I am not sure - looking at the optical image I would of said the object on the right is a star. SkyServer has it listed as a galaxy.
Sadly - the bottom right object is a star from our own galaxy.
At the center? Not a star - a very faint galaxy.
I would agree. #toofainttoclassify
Looking at it, I would say yes 😃
No it is not an arc 😦 Something went very wrong with this image.
Sorry - no merger, the orange blob is a star from our own galaxy.
Not really 😃 A stunning barred spiral, still a bit undefined but give it a few millenia..
@Wisi_Eu but classifying the image you would not know that 😉
Welcome 😃 and happy hunting!
The UKIDSS images are sometimes difficult to classify, but I would of done the same.
Hi nicro46 - It has a quasar at its core, and that is what is causing the weird colour - you should take a look at the spectra 😃
A disturbed galaxy with spiral features - this is an infrared image, so it looks a bit weird.
It is a galaxy with a very bright core 😃
SkyServer has it flagged as a star. Looking at the optical image I am inclined to agree.
No lensing 😃 A chance alignment - the blue objects are both stars from our own galaxy
Looks like a typical spiral arm to me. We can rule out tidal arm as I do not see an interacting galaxy. The spectra rules out QSO.
The bluish green object is a star, the 'tail' is an artifact.
I think that is an artifact as it is not visible in the optical image.
Mmmmm, I think it might have a spiral pattern 😃 Just a bit undefined...
No lensing - the blue objects are both star from our galaxy 😃
Es un sendero de satélite - que se mueven con rapidez, por lo que sólo se capturan en un solo color.
The bright object in the top left corner?
Looks like we had a problem with the chip.... Processing error.
It is another galaxy, but without the redshift of both it is difficult to say if they are related. Thinking #overlap is more likely.
I do not think it is an elliptical, thinking more likely lenticular or edge on. Have you tried looking at it on SkyServer?
lol 😃
According to Skyserver both the objects are galaxies, I think #overlap as I do not see much interaction. Also, this is an infrared image 😃
In this case I will say misaligned filter - the same artifact is visible on other objects in the image.
It is a #star - stunning! Welcome 😃
That is an artifact - I have only seen this type cropping up in the past few days. If you look at the optical image it disappears 😃
On the top right they are other galaxies 😃 Bottom right a star.
#QSO
Wow - that is an awesome one!
I don't think it is a merger, no interaction. I would go with #overlap
I would say the same...
No exploding stars 😃 A chance alignment between a distant galaxy and a star from our own galaxy.
Not a nebula, but a galaxy 😃
2/2 ...visible in other object when viewed in SkyServer. Artifact perhaps? Anyone else?
1/2 I don't think it is a lens (or arc) , as we would expect it to have a different color to the lens galaxy. The discolouration is also...
I would of classified it as having spiral features - but your opinion is more important 😃 There is no such thing as a wrong answer...
It could also be an #overlap or #sattelite_galaxy - difficult to tell without the redshift of both galaxies.
Foreground #star for me!
Star forming? Yes, it is - we can tell by looking at the colours and the structure of the galaxy 😃
It looks like a late stage merger. This is a UKIDSS image, so it was taken in the infrared, that would account for the strange color
Sadly not:-) It is a star from our own galaxy
No lensing 😃 just star formation in a spiral galaxy.
It is an artifact - look here for more info: http://tinyurl.com/GZartifacts
Difficult to tell as we don't have the redshift of either object - #overlap is also a possibility.
I would go with #spiral features and #bar 😃
Hi and welcome ghareth 😃 that is an artifact at the center of the galaxy. See here for more info: http://tinyurl.com/GZartifacts
I do not think it is a merger - looks like it is a single galaxy!
It does look quite busy, but I am not sure if we could call it a cluster?
I think it is just a chance alignment - no merging for me.
That is an artifact - first time I have seen one like that!
Wow, that is a nice one!
Looks like something went wrong with one of the filters or the image processing.
Both are stars from our own galaxy 😃
Not too sure, the optical image is also very noisy. Looks like a merger, so it is quite disturbed.
Not a dust lane - we have 2 distinct cores - I personally would go with merger.
I would also go with #overlap
That is an artifact 😃
I would say it is a post merger. I do not think the galaxy on the bottom left is connected to it.
You could try looking at it using Galaxy Zoo examine?
The galaxy has a #dustlane, that would account for the redness you are seeing.
here you go! http://talk.galaxyzoo.org/#/boards/BGZ0000005/discussions/DGZ0000lv2
Looking at the respective redshifts (z=0.049 vs 0.066) I would personally go with #overlap.
lol - Els beat me to it!
I would agree with both of you 😃
It is an artifact - there are several in this image.
And you would be correct 😃 Have you tried looking at your galaxy using 'examine'? It really is spectacular!
It is an artifact 😃 In this case, the core of the galaxy was too bright for the camera and the image became over saturated.
We are not too sure what causes this type of artifact, but it could be due to a reflection within the camera itself.
Hi Gapella, I do not think it is a voorwerpie, the color distortion could be due to a bright star off screen.
It is a satellite trail - see ElisabethB's answer below 😃
And you would be correct!
That looks like a classic E0 elliptical galaxy, totally undisturbed - nice!
It is an #Artifact
Sorry! - I am not too sure what is happening.
No, it is not exploding, but it is a star from our own galaxy!
I would go with 3 stars 😃
Hmmm, I don't think this galaxy has a dust lane, looks like the discoloration is an artifact (for me anyway!)
The stars?
I would personally go with merger
They are artifacts, not too sure what causes them
See right for answer ->
The red center is an artifact caused by the brightness of the galactic core, NED does have the galaxy flagged as having a radio source.
and you would be correct!
I would go with spiral
That is star from our galaxy 😃
It is an #edgeon galaxy at the center
Foreground stars do not have the mass to cause lensing that would be apparent in these images 😃 Spiral galaxy perhaps?
No lens or arc for me - it looks like the galaxy has some spiral features
Hi Tsourakla, remember to classify the object at the center of the image - but yes, the other bright objects are stars 😃
Or a galaxy with 2 stars 😉 Difficult to tell looking at the image, but SkyServer has the northmost object listed as a star.
Remember this is a infrared image, so the galaxy will look quite different in the optical!
Another #diffraction_spike from a bright star off screen
I don't think it is interacting with anything, the odd discolouration is an artifact caused by the edge of the strip.
@eben.bosman - I have just been reliably informed there is no such thread - so I will make one 😃 May take a day or two...
It is a galaxy 😃
A #diffraction spike from a very bright star off screen.
Looks like a #tidal_trail they are usually caused by merging / interacting galaxies.
No UFOS's - just an artifact 😃
No, it is not a lens. It is too diffused and the lens galaxy does not have enough mass to cause an arc of that size.
..how to use it - but that will have to wait till tonight. Sorry, but I need to go to work.
click on 'View in Galaxy Zoo examine' just under the image above, and that will take you to tools. I will try and find a thread to explain..
Yes, that is a star under the galaxy. The galaxy looks very disturbed, even in the optical. Have you used the GZ examine tools?
In this case I would go with irregular.
Sure looks like it! Nice!
Some of the images are cleaned up to remove satellite trails, sometimes not all the pixels are removed.
It is a star - they do look a bit different in infrared.
#merger 😃 It is more apparent in the optical - but there is nice interaction.
I am happy with ElsB assessment that it is likely that there is an AGN at the center 😃
I am getting somewhat conflicting results in the various catalogues - there is a QSO somewhere in the image, but can't quite pinpoint it...
That is what NED says - I could have a second, more in-depth look, and that might take a bit longer - but it still looks like one to me 😃
Aha - NED has it listed as a QSO - that would explain the brightness 😃
It is an artifact - caused by a really bright core.
You are right - it is a sun of sorts - it is a star from our own galaxy 😃
No worries 😃
No lensing @MartinTheK
They are foreground stars - And please remember your language, we are a family friendly site 😃
Yes, thats correct 😃
I think there might be more going on here. #Polar_ring perhaps?
Thats correct 😃 Remember these are infrared images, so the colour will be different in the optical.
II think it could just be an artifact, there is a similar coloured dot in the 11 of the galaxy, halfway to the edge.
No defect - the googly eyes are in fact stars from own own galaxy! Here is some more info: http://tinyurl.com/pbo34r2
I think it is a slight artifact, you can see similar discoloration elsewhere in the image.
No spectra so it is difficult to tell from just looking, but that quite a bright core. Also not flagged as having a QSO.
The redshift is quite similar (0.71 and 0.72) so they are quite close, can't see a lot of interaction. Nice #dustlane!
an #elliptical_galaxy
That is a star from our own galaxy - it looks so strange because its brightness overwhelmed the camera. http://tinyurl.com/pbo34r2
I think I do see a hint of a bulge 😉
No, but it is showing a few galaxies and a lot of stars - must be a cluster. Have you tried using Galaxy Zoo examine?
It is a artifact - if the core of the galaxy is very bright it can cause some complications with the imaging.
No lensing or a ring - Sorry! The bright core of the galaxy has overwhelmed the camera leading to an artifact at the center.
On SkyServer, the bright object in the 8 of the galaxy is a star, but the galaxy is very disturbed. Possible mid to late stage #Merger
Looking at it 'as is' - it seems like a disturbed spiral.
A galaxy at the centre 😃
I am not seeing any darkness - are you referring to the galaxy itself, or to the upper left from the galaxy?
No, it is a galaxy - it looks a bit strange as there is some discolouration (due to brightness) at the centre 😃
It is a star - non exploding 😉 Have a look here for more info : http://tinyurl.com/pbo34r2
I would go with that!
That is a star from our own galaxy 😃 Looks a bit weird due to over saturation.
It is an optical artifact as it is not present in the SkyServer image...
I will go with #merger - definitely not lensing, and there is a lot of interaction between the two.
Myself - loose 2 armed spiral - sometimes it is difficult to interpret an image, but don't be afraid of classifying what you see 😃
a #barred #spiral , look like we may have an #inner_ring
The bar is oblique across the bulge - not very big, but the arms extend from it on either end.
Wow, that is a good example! #xbulge
A #barred #ring galaxy - very nice! Looks like we may have an outer or polar ring as well 😃
No merger - the galaxy is in the middle of a star cluster, so it is a chance alignment 😃
The blue line is a satellite trail that was only captured in the blue filter.
They are optical artifacts caused by the bright stars - this thread has more info http://tinyurl.com/pbo34r2
Those are #arftifacts - have you read this thread: http://tinyurl.com/pbo34r2 really helpful!
Sadly not - an optical artifact 😦
You are correct - it is a #star 😃
Both of those blue objects are stars from our own galaxy - have you read this: http://tinyurl.com/pbo34r2
Hi 😃 That is a star from our own galaxy - have you read this http://tinyurl.com/pbo34r2
Yes, it is a star - the color is not true.

2/2: ...in this case it is the hub or core of the galaxy.
1/2: The 2 darker circles are artifacts - no back holes in sight! The 3rd red one is an optical artifact caused by a really bright object...
Hi Lana4Light 😃 do you have a question about this galaxy?
I would go with #overlap = also stunning #bar and #ring
Not so sure about ring, but we do have spiral features - sometimes difficult to tell between the 2 when the galaxy is this fuzzy.
Hmmm, it think it is just a chance alignment. The galaxy looks too lightweight to cause strong gravitational lensing.
You are correct - they are artifacts - have you read this: http://tinyurl.com/pbo34r2
It is data from SkyServer / NED - it is the redshift of the two galaxies. They are at different distances, so it is an overlap not a merger.
I would go with a #merger of 2 ellipticals, they are quite #disturbed due to interaction.
It is difficult to tell in this case, but it looks like the tiny orange elliptical at the center.
I would also flag it as having a #bar and a #ring - I find going with your gut instinct is the best advice.
The one directly at the center, in this case it is the smaller smooth elliptical. The 2 objects on the right hand side are stars.
Dense areas of star formation - young stars are hot and blue, that is what is causing the discolouration in the arms.
Hi @BernardS88, do you have a question?
No black holes 😉 - I would say #merger as there does appear to be interaction.
You are correct - they are artifacts.
In this case I would say coincidence. You are correct, when taking into account the vast distances, any companions would be quite close by.
I would say neither. I would be inclined to classify it as star or artifact to flag it up, but ElisabethB would be able to confirm that.
Yes, that would be a classic sign of a merger. We would call it a tidal trail. In this case, quite possibly a #merger.
I would say yes #merger - Nice interaction between the two.
That is more definitely a galaxy 😃
BTW remember to classify the object at the center, in this case it is the rather dull, somewhat disturbed galaxy.
That bright object on the left is a star from our own galaxy - so no lensing 😃 Have you read this: http://tinyurl.com/pbo34r2
It might even have a bar... 😃
It is an artifact - for more info read this: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
Remember to classify the object at the center of the image - the bright blue object at the top is a star from our own galaxy.
That is a star from our own galaxy - the Milky Way 😃 More info: http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh
It is an artifact caused by oversaturation. Happens with really bright objects, in thus case the galactic core.
I am not seeing any interaction between the two, so chance alignment for me.
No merger 😃 The blue star is in our galaxy, the orange elliptical is many light years away.
Could also be a flyby? The centre galaxy does look somewhat disturbed. Pity we have no spectra.
Difficult to tell as the galaxy is very undefined in both the infrared and optical. My experience says no - sorry.
Hi @isadora do you have a question?
I dont think it is a artifact, it is also visible in the optical. QSO perhaps? Not a lot on SkyServey or NED. Also, no spectra.
It is not an artifact -I would say galaxy. Pondering between #dwarf or #irregular.
I am going to go with a star cluster within our galaxy. Could be wrong - anyone else?
3/3.. of the stars into account. So, the geo satellites would still move very slowing across the frame, but not leave much of a trail.
2/3... would not move as the satellite would be in a fixed position in relation to the earth. Edd pointed out I had not taken the movement..
1/3 ... I asked Edd (one of the GZ Scientist) how a geosynchronous satellite would look in these images. My thinking was that they...
Wow, that is stunning!
I would say satellite trails
Just one that is quite disturbed 😃 Spiral arms all over the place!
Hi @turelli - I am unfamiliar with this GPair hashtag, can you explain it for me?
Remember to classify the galaxy at the center 😃 and yes, the galaxy on the right has 2 spiral arms.
No ring - just an amazing #spiral viewed at the oblique. Nice dust lanes.
I would go with #dwarf or #irregular
Misaligned images between filters - Sorry!
Looking at SkyServer the orange thingy is another galaxy, but this image is very misaligned. I think you analysed the image quite well 😃
It is a foreground from our own galaxy - the Milky Way.
It is an artifact caused by the camera.
As ElsB said it is a optical artifact - happy hunting!
It is not unheard of 😃 Nice Example - also hints of a #bar
possible #sattelite_galaxy at the end of one of the spiral arms.
The blue ring bottom right is a #star from our own galaxy 😃 Same for the object in the 12:30 from the galactic hub of the centre galaxy
looks like an #edge_on galaxy
They are artifacts 😃
Wow, that is a gorgeous one!
The bright object at the bottom is a star from our galaxy, and the 'ray' extending from it is a diffraction spike (a optical artifact) 😃
I do see some spiral features 😉
2 galaxies 😃 with a third and forth to the bottom left.
#ring
It is difficult to tell without the spectra of the 3 galaxies. I do not see much interaction, so perhaps early stage?
Thanks Els, I also suspected barred, it just looked really odd!
...hub, rather oblique compared to the rest of the galaxy. ElsB?
Just got this... according to SkySurvey this is a single galaxy. We can discount the blue object on the right as it is a star, unusual...
No worries 😃
I do not think that is a dust lane, more likely to be an optical artifact. E0 elliptical for me.
Interesting thought non- the-less 😃
Not likely - you can still see the trail on either side that has been cleaned up by digital processing.
No 😃 That is a star from our own galaxy.
Why would you think it has a quasar?
Visually looking at the image there are signs of interaction. Spiral arm at top is somewhat displaced - Tidal tail? possible #merger
Difficult to tell, not seeing much interaction. More likely chance overlap?
Looking at the image itself, cluster of galaxies. The 'closest' star is the bright blue object to the left.
I prefer to think of it as two galaxies dancing around each other 😄 #merger
No supernova 😃 A star from within our own galaxy!
Not so much a single filter, rather a slight misalignment between 3 (?) plates/filters.
It is not lensing 😃 or a star. The galaxy does have some features of a spiral, but not quite.
Arcs will be centered around the maxima of the galaxy - so they tend to be at the same distance from the hub or core. This is clearly spiral
In this case it is not an arc (or gravitational lens) - spiral arms with star formation.
There is a slight #bar - looks like the arms are settling into a #ring.
I will go with star 😃
The center galaxy looks a bit lightweight to have a satellite galaxy, with no spectra I will say chance alignment.
No, I do not think it is overlapped with a star. Possible QSO?
Artifacts again - if you look at the optical image they are not there.
Those are optical artifacts 😃
I would say it looks good #ring
@Wisi_EU: it is a matter of perspective 😃 I may need to rewatch SW this weekend, to clarify the, eeerrrr... science behind lightsabres 😃
@Wisi_Eu I would go with #lightssabre personally 😉 Sorry, needed to be done!
It is amazing 😄 Gotta love those stars!
Just viewing the image (as is) I would say yes. Nice tidal trails. Have you tried examining it closer?
I would go with #overlap. I am not seeing any interaction between the galaxies. Pity we only have spectra on the centre galaxy/
A somewhat disturbed #spiral possible #bar
I do not think it is a merger, as there is not a lot of disturbance / tidal debris in the center galaxy.
That is a star from our own galaxy 😃
I am not so sure I see any dustlanes in this galaxy. Some spiral features, and possibly a companion galaxy in the 12. Nice #asteroid
You beat me to it 😄
I would say yes, but ElsB would be able to confirm that 😃
Wow, this is a lovely one 😃 Agree with all the comments below!
Nice #ring - would you say there is also a slight appearance of a bar?
Hi Bob, it is a satellite trail.
