Galaxy Zoo Talk
That looks like a fairly normal edgeon spiral to me - just behind a satellite trail (or some other bright defect).
Neat. That'd be a good #zgotw (is that the right tag I forget!).
Could be a bar seen edge on - sometimes those create very clear X-shapes. Not possible to tell without higher res imaging.
That's a very beautiful spiral galaxy. I like how the knots of star formation pick out the spirals
(as best you can obviously given it's partially obscured).
Well yes and no. Obviously there's a bright foreground star, but it would also help us if you could classify the galaxy in the middle.
That's beautiful. Pity about the imaging defect from the bright star just off the top of the image.
Hey @jeffreyhrwtz what do you like so much about this one? Looks like a pretty normal dwarf irregular to me. 😃
It kind of does - those are just two coincidentally aligned stars in our own galaxy however - much much closer that the galaxy in the middle
Yeah that's stunning.
It's likely a bar viewed end-on causing the "X-shaped" bulge. 😃
Any of the three galaxies (I spy one just behind the central one). Awesome find.
We'd call that a "warped disc" - it it's not flat like a CD, but bent. Nice find. Definite #merger I would guess.
What the right at right is I have no idea - some kind of imaging defect I guess.
Actually I'm pretty sure that's a bright elliptical galaxy in the centre. It's extended beyond a point source, and doesn't have the spikes
A nice looking #overlap there - just peeking out from behind! Bet Bill would love this one. 😃
Usually we don't image too close to our own galaxy - as you cannot see the galaxies behind well.
So it's 8degrees South of the Galactic plane. Fairly close. Quite near to the edge of the imaging we have.
I suspect a lot of foreground dust too - that's why it looks so red.
If you follow the link through Galaxy Zoo examine I bet you will find this is in/near the plane of our own Galaxy.
Even with all my years working to study these, I sometimes look at images like this just in awe of the beauty.
Wow that one is beautiful.
Might be a blue star superimposed on the galaxy... or might be the blue dot is associated. Impossible to tell without a spectrum
That one is stunning. 😃
Oooh that one is stunning.
Agreed - that's a wow image!
Nice #ring in DeCaLs which you can't see in the SDSS imaging at all. 😃
Not sure that's an asteroid. Could just be a cosmic ray - only in the red image, so must have been moving quick.
Hi @bluemagi - what do you mean by that comment? This looks like a galaxy to me, and it's a DECaLS image....
Lovely faint spirals. Made me curious if we could see them in the SDSS image.
but it's very competitive. 😃
Specific to MaNGA - most of the targets are set already. There's a process to submit sets of interesting targets for spare bundles....
I think it's likely just a lenticular like galaxy with a bar. We do see them.
That red blob might be interesting.... (or might be a foreground star). Do you know how to use Galaxy Zoo examine to look at other data?
Yeah I'd agree that looks like a fairly advanced state of a fairly major merger. 😃
Possibly a #merger
It's a foreground star just out of the image. The spike is a "diffraction spike" from it.
I don't think they are stars, because they look extended. I'd guess a galaxy merger.
That's a nice #overlap (I think - they don't look interacting). #ZGOTW
Yeah probably that bright star messed up the size estimate (which is based on the SDSS image).
@shocko61 - why do you think that's a supernova instead of a foreground star? Have you looked up more details?
This would be a good one for #ZGOTW
Yeah that is hard. If I was pushed I'd guess it's a low mass disc with a bar.... but hard to tell.
This is another example of an image which the computer fit has given us a #wrongsize
We should have been more zoomed in. We use a computer fit to estimate the right size to show, and this time it didn't work.
Unfortunately it's the #wrongsize
Agreed - they're clumps of star formation in this simulated galaxy. But it does look a bit odd.
I can tell it's old, also because there are no narrow emission lines, and the spectrum is very red. 😃
An AGN would show broad emission lines in the spectrum (which I don't see)
It is very bright though, it's a relatively compact collection of stars in the centre of this old galaxy.
That tells me immediately it's not an AGN
If you click through "Galaxy Zoo examine" and then "SDSS Skyviewer" you can see the spectrum of this.
Honestly I'd have assumed it was a foreground star, but photozs can be quite good these days.
They're pretty rare, but could try for a #quasaroverlap tag....
Oh - that's potentially useful Quasars behind galaxies can be used to probe material in galaxy which does not emit, but only absorbs light
Not sure that's an artifact as such - looks like a star to me, that's a bit over exposed so the colour gets messed up.
That's a fantastic looking #illustris_spiral
This is a simulated galaxy, and an example of one that looks (to me) quite fake. Something not quite right in the simulation yet. 😃
There's no prominent centre - still a centre. The blue shows up regions of starformation.
Yeah - artifact (I can tell because it's not present in the SDSS Skyviewer image) - get to via "Galaxy Zoo examine" link
I think it's an image artifact, but I could be wrong.....
We just talked about this object on our bi-weekly science team chat. We all agreed we'd never seen a galaxy like this before!
It might be an edge-on disc. But hard to tell from this image. Just always do your best. 😃
I love that comment!
Looks like a star which has an unusual colour, or messed up the colourisation of the image.
That's an artifact. It's an image of a bright star, which has fooled the computers into thinking it's a galaxy somehow.
Wow that is stunning. Really an unusual looking galaxy.
It's hard to tell, but I think it might be yes.
It's so hard to tell without a distances.
Might be a star, might be a dwarf galaxy satellite - or potentially even an unconnected background galaxy.
Really subtle disc here - how many of you would classify this as smooth?
I see all sorts of faint "fluff" to the upper right. Might be #tidaldebris
I'd say more likely an #overlap than a merger. The two galaxies don't look disturbed to me.
Might just be a very unusual looking #minormerger? The universe is a big place.
Might be a #satellite trail across the DECaLS image. I'm not too familiar with how they look. If possible classify the galaxy underneath. 😃
Definitely. There's a chance it's a quasar, but more likely a star. This will be very helpful for the DECaLS team.
Oh yeah that's a nice one. Good find @Susan. 😃
Thanks for helping us to put a proper number to that vague statement.
Yeah - this is one of the simulated galaxies and we do see a large number of these ring features.
Nice #illustris #spiral I think.
Stunning #barless #spiral from #DECaLS. Should be lots of nice ones in now. 😃
Even more when you realise it's a collection of billions of stars (or at least in my view).
Tiny bulge, unless that's a post source revealing an AGN…. @vrooje?
Anyway most of them should show some features.
There you can see a faint outer spiral, which is too faint to be detected in this UV image.
Looks really nice in colour too: http://skyserver.sdss.org/dr8/en/tools/chart/chart.asp?ra=195.64888698&dec=41.32336789
Really nice ring. I love these galaxies which just show the orbits of the stars so clearly.
These images were all selected to have features (in the colour images) - we're testing to see if they can be seen in all separately.
That's a classic example of a spiral galaxy with a large bar.
Well the link will (still need to figure out how to embed an image here).
This might work: http://skyservice.pha.jhu.edu/DR8/ImgCutout/getjpeg.aspx?ra=188.40837485&dec=20.23964809&scale=0.19806&width=512&height=512
Glad you like it. 😃 Check out the links via "Galaxy Zoo examine" to see it in colour also. 😃
Probably just some sort of atifact. @vrooje is more expert on these types of images (from the Hubble Space Telescope) so might comment more
You'll see they're quite blue - which supports the idea of them being star formation regions. 😃
If you look at the colour image: http://skyserver.sdss.org/dr8/en/tools/explore/obj.asp?id=1237664337179639837
It is really neat. They are likely star forming regions - dense knots of gas in which new stars are forming.
I wouldn't call that smooth. I see a bar and clear spiral structure….
That is really beautiful.
That looks way to straight to be real - I bet its an artifact.
Here's the link: http://skyserver.sdss.org/dr8/en/tools/explore/obj.asp?id=1237663917341409326
Another #imagesize wrong. Beautiful spiral in SkyServer.
That's a galactic bar. Classic example. 😃
Actually looks pretty strange in 3 colours - this is probably disturbed.
The reason we're asking for classifications in just one colour is explained on the blog (blog.galaxyzoo.org)
If you follow the "Galaxy Zoo Examine" link you can click through to the 3 colour image from SDSS.
Very lopsided outer disc here.
Actually you can see it better in the gri image: http://skyserver.sdss.org/dr8/en/tools/chart/chart.asp?ra=119.65217319&dec=12.16350446
Was curious if the single filter brought out the low surface brightness arms more.
Hmm. Looks like another #imagesizewrong #incorrectly sized. I'll chase down this issue tomorrow.
Totally agree. #imagesizewrong here too.
Tagging as #imagesizewrong so I can find this again to check up on.
Even more impressive in colour. Pity as the central galaxy is pretty nice more zoomed in.
Looks like a giant MacDonalds in space! This is one image which clearly went very wrong being stitched together!
I know. I feel exactly the same way when I look at them. That's a particularly beautiful one. 😃
Nice spiral. 😃
I think I can just still make out a bar and spiral arms though.
I was right. Galaxies are really patchy in the UV as you only see the youngest brightest stars really.
Going to guess this is a u-band (UV) image, and then check in examine. 😃
I agree - this ones a lovely one from the HST CANDELS set. 😃
I'm not sure if it's a lens or not. Bit hard to tell honestly…..
That one is #beautiful.
That's a beautiful merger (or possibly overlap?).
Some sort of artifact causing the green blobs I'd guess.
If you click for example images on the "Clumpy" question you'll see better what we mean by that question. 😃
That's beautiful. I don't think I'd really call it clumpy, those blue dots are likely star forming regions
Looks like a clumpy galaxy, so I would go down the clumpy question tree with something like this.
Really nice barred spiral in Hubble image.
Cool how it illustrates galaxies here get reddened by the dust from our own Galaxy.
Was wondering if we had a galaxy which looked like a goat for the #yearofthegoat - should have realised of course we would!
Lovely edgeon disc with a dust lane.
That's a stunning pair. 😃
Hard to tell if it's irregular (i.e.. patchy star formation) or disturbed due to some interaction. Nice low mass galaxy.
Really skinny edge on disc - and looks at bit disturbed.
Might be a #merger to the top right, or could be a SF clump. I like how it looks almost purple!
It's definitely a disc galaxy which is rotating. The #bar and #spiral arms only form in that kind of galaxy.
We always just ask the central object be classified. In this case it looks like a #star or #artifact. Thanks for the classifications. 😃
The orange blobs are likely stars in our galaxy. The blob to the right of the central galaxy, could be background, or small companion.
My best guess is a disc seen edge-on. If you look at the i-band image in examine you can see a dust lane I think.
Amazing what orbital dynamics can do sometimes to how galaxies look!
That's very nice. 😃
That is a lovely barred galaxy.
Would make a great #D in the #alphabet
Donuts in space! Not really - it's some kind of image artifact (mistake in focus I think). 😃
Yeah I'd guess the star field is too dense so it hasn't split the objects up correctly.
If you want to start a discussion about that collection please do. 😃
@vrooje made a tag collection with #ugc which now appears to the right
Looks quite regular actually - we usually reserve the term disturbed for things which are very asymmetric. This has quite balanced 2-arms
This one's very pretty. Would make a nice #zgotw or #ootw talking about low surface brightness or irregular galaxies.
Might not be an overlap - could be a minor merger….
Oooh - definitely an #zgotw (Zooniverse Galaxy of the Week) candidate. 😃
That's a ring which you can almost see forming. #beautiful.
Like @ElisabethB already said 2 years ago! 😉
The blue fuzz being a low surface brightness patchy irregular in the foreground.
I think that might actually be an #overlap. The orange blob being a background galaxy.
Wonder if the blue just below the linear feature is real...
That's a stunning #ngc object. 😃
Oh cool. I guess overlapping the galaxy like that makes the pipeline break. #cosmicray
That's neat. A lot going on in this image!
That could be an #asteroid although it's a weird looking one if so.
Oooh - almost like the sombrero galaxy, just slightly smaller bulge. Nice. 😃
That is very #beautiful
Hmm. Lenses are not my main expertise, but I think this is not curvy enough…. Also not symmetric.
That's one #beautiful #overlap. Chance alignments like this always make me amazed at the size of the Universe.
Ooh that one is #beautiful
It could be two galaxies just happened to line up perfectly - although that seems unlikely, so more likely a single galaxy. 😃
Reminded of this today and wanted to tag it #beautiful so symmetric.
Looks like a collision ring to me. A bit like the Cartwheel Galaxy. http://en.wikipedia.org/wiki/Cartwheel_Galaxy
I think it is an artefact. And I think this is a group of stars which have been misclassified as a galaxy by the automated pipeline.
I think maybe there's a really faint disc here.
Odd speckling #artifact from UKIDSS.
PS. The orientation of the two images is not the same. 😃
The SDSS optical images are deeper than the UKIDSS, and more sensitive to the stars in the disc, so show the spiral more.
Now this is an intimidating page - it's a professional astronomer data access page, but it also has the optical image.
Here's the direct link to it: http://skyserver.sdss3.org/dr8/en/tools/explore/obj.asp?id=1237659754986340481
To the right of that image is a bunch more information, and some links. If you click on "View on Skyserver" you get the SDSS image.
And below that it says "View in Galaxy Zoo examine". If you click on that you get a page with the image on it.
The below that is the RA and Dec of the image (just co-ordinates on the sky)
Mike - if you look below the image you can see "UKIDSS" (which is the survey this image is from)
That's a pretty crazy image to have got through. It's an #artifact, but very pretty one. 😃
Yeah looks like the automated galaxy finder got confused by so many stars.
What makes you think that?
That's a beautiful example of a diffraction spike from a #brightstar. Would be useful as a teaching tool in optics classes.
That's a lovely example of an #asteroid in front of a galaxy.
If you click through "Galaxy Zoo examine" you can see the SDSS image, which reveals a clear disc, probably a spiral.
Cool effect of the three stars in a line above the galaxy! Almost like traffic lights. 😃
What is is about this image you like? The object to the lower right is probably a #star in our galaxy. The middle one is a galaxy. 😃
Ooh I think you're right that is a candidate. If you do #lens our lensing buddies from @spacewarps might pick it up. 😃
Yeah I would guess that's a foreground star.
Sometimes galaxies are just much fainter in the NIR than in optical, so this is obviously one of those. Try looking at optical in "examine"
Why do you think that? Have you looked at the spectrum, or just think you can see a point source in the middle?
To help the #overlap group we can tag it as such, also tag as #merger
That's lovely. Without redshifts it's hard to tell if it's a merger or an overlap. I'd be included to guess the latter, but not sure.
Also quite nice looking in optical (this is NIR) http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=228.30905065&dec=8.04640639
It certainly is!
Looks quite blue in the outer parts though. Which UV survey have you looked for. Sure it was observed?
That's a stunning barred spiral. Gorgeous.
But it's definitely some kind of imaging artifact. You can see it does not appear in the SDSS images of the same galaxy.
That is funky looking... This is a UKIDSS (IR) image. I'm not as familiar with these as SDSS, so not sure what it is...
Well I would say 2, but it's often not a totally unique answer - this is why we like to have ~20-40 people classify each galaxy.
Looks like a meat hook to me....
Must have confused the SDSS galaxy identification routines. 😃 Hope you marked it "star or artifact"!
The multi-coloured blob to the left is an #asteroid
That is wierd looking I agree. I think they are stars, but it is a bit hard to tell.
Good memory. It's really helpful for us to have classifications of these objects to improve the science from GZH classifications.
Well there's a star just to the upper left of centre, but I think the edge -on disc galaxy is in the middle.... #alwaysclassifythecentre
It's quite a high redshift (distant) galaxy, so there should be new stars forming....
Looks like a very low surface brightness face-on disc with possibly a weak #bar
OK so more discussion of this on the science email list. The conclusion seems to be that it's a reflection from bright nearby star.
It's just a coincidence that it's right next to the galaxy. And now I'll stop talking to myself! 😉
That's a bright #star at the top left. The lines are diffraction spikes (an effects of optics).
With thanks to Edd Edmondson (who made all these lovely images) it seems to be an artefact - not real. We're chasing down what from/why.
I don't know what the green thing is. It's not visible in the optical image....
Also interesting - the lens is not really obvious in the optical image (get to via "examine" and "see on SkyServer").
That's an awesome #lens seen in the IR image!
That's a nice example of a #dustlane. Something you can make in the "odd" category when classifying.
That's a beautiful spiral. So symmetric. And so little evidence of any bar.
That's really a stunning example of #bars, #rings and orbital resonances (the nodes at the end of the bar). Lovely. 😃
That's a beautiful merger. 😃
That's a lovely galaxy. 😃
Very very unbarred which is interesting.... (to me anyway!).
That's a really neat #dustlane - interesting that it's apparently not in the same plane as the disc....
..... but for these normal morphological features we get that from the classifications and don't need it here.
By the way, if you're enjoying putting hashtags on lots of galaxies just get on with it....
What do you find odd about this? Looks like a normal face on disk to me. Maybe a #bar.
Absolutely every galaxy we think has a supermassive blackhole in its centre. So this one would be part of this.
If you click on your hashtag you get a bunch of examples of #polar-ring galaxies.
I don't think so, but what in the image makes you think that? I might be wrong....
Absolutely a satellite trail. Something moving very fast only picked up in the green image.
I agree - I would guess there's a star almost directly in front of the galaxy.
Mostly likely two stars in front (the lower two) and a single centre, I think. But it's hard to tell. 😃
A nice fairly edge-on galaxy
#asteroid found at Portsmouth skeptics in the pub demo.
Definitely I would say that galaxy is too low surface brightness (too faint) to get a useful classification.
That one's a stunner. 😃
That orange thing in the middle is still a real galaxy though. Amazing the SDSS pipeline could pick that out so close to the foreground star
I think that green stuff is just light spill - hard to tell even in the Skyserver zoomed out image (follow links through "examine").
I don't see the asteroid...
Nice explanation of a #satellite trail ElisabethB. 😃 Also this image is an #edgeoffield
But that is where the supermassive black hole would be in this galaxy.
The dimmer spot in the centre of the galaxy is probably an image artifact.
Hi. You're quite right the greenish round thing is a star in our galaxy which just happens to be in front of the galaxy in the image.
If I look at the h-band image in Examine (http://www.galaxyzoo.org/#/examine/AGZ0000vzl) looks like the middle object definitely a star.
Above it there are two edge-on galaxies, probably at different distances (ie. not merging).
Well we're asking about the central (red) object, which looks pretty featureless - might be a star even...
Wow nice cluster image. 😃 In images like this we're asking for a classification of the very central galaxy. Which to me looks like a disc.
That's a really neat cluster of galaxies.
I see a barred two arm spiral too - albeit a slightly irregular one. The greenish stuff in front of/in one arm looks interesting...
Wow that must be very far away!
The blue - red - green comes about because it moves between images taken in the different filters!
lynjac - what that is is very cool - I think it's an #asteroid passing in front of the galaxy.
They look like stars - the PSF obviously gone a bit odd in this image. Check out Skyserver and zoom out and it becomes clear
Why do you think it might be? Hard to tell between a small bulge and a point source in middle. #vrooje is the best at it! No spectra, so idk
Reminds me a bit of Hoag's object. Sometimes spirals look a bit like rings (and vice versa). They are related. So pretty. 😃
You're welcome. Thanks for the classifications. I'm glad you're enjoying the site.
A small group really I would say. 😃
I agree with Elisabeth. A lovely #irregular galaxy.
Might indicate that this is the advanced stage of a #merger - and that "streak" is a remnant tidal tail. Thanks for the classifications. 😃
Click through "Galaxy Zoo examine" and you can get a great wider view showing it's a lovely #merger
And #3arms in the spiral. That makes it unusual too. 😃
Almost looks like it has two perpendicular bars! Weird. Thanks for pointing it out.
I would this think this is a merger with a ring too. I'll be interested in the results of your model Phil.
I see the tiny smudge of blue Brooke. Might be worth looking at this one in single filter images?
Yes that's definitely got a #bar. And a #ring. And I thin I can see a faint outer spiral.
Not surprising with all that disturbance and related shocks going through the gas. 😃
NED says it's NGC1614 at z=0.02. And lucky us - there is a HST image of it already. http://www.spacetelescope.org/images/heic0810ax/
That's really lovely. Would make a great b for the #alphabet (rotated) too. 😃
That is a wierd thing. Looks like it could be a #merger
NGC 3800 is just a much bigger galaxy than NGC 3799. That's all. 😃
Amazing to catch an #asteroid passing in front of a galaxy!
It seems the larger complex is called the Orion B star forming region, but exactly which bit of it this is is not clear to me.
Wow that's beautiful. Definitely not a galaxy though! 😉 Seems to be a known molecular cloud in which new stars are forming.
That's definitely an #artifact, probably #satellite trail. Too green to be a galaxy. 😃
That's a stunning #irregular galaxy I think. 😃
I think I can just make out a possible satellite galaxy to the extreme left of the image.
#Beautiful. Might be some kind of tidal disturbance pulling out the outer arm, or just very extended star formation.
Look at all those extended sources (galaxies) in the image though. Stunning!
I think this is an example where that bright star has messed up the photometry and so the image is shown on the wrong scale for the galaxy.
Then you can see if they have known redshifts and check if they are similar (so a merger), or really different (then an overlap).
Hard to tell. Might just be a chance alignment. Try to follow the links through "examine" to go to "Sky server" and then "NED".
Probably just a blue galaxy which is merging with the red one and creating that tidal tail. Beautiful colour contrast though. 😃
Given the colour I'd guess it's part of a spiral arm, or some stream of stars tidally stripped off. Some kind of advanced merger perhaps..
Very wierd - just a very disturbed disc galaxy I think.
Hard to tell with this one. Could also be a minor #merger going on.
What a perfect set of twin galaxies though. Another example of how vast the universe is. 😃
The pair has the lovely name: MCG -01-03-008
Wow that's stunning. A quick search in NED and it's a known interacting pair. They both have redshifts measured (which are similar).
Looks like an #overlap to me too. Think I can even see dust lanes from the larger edge-on going across the smaller one (at bottom). Nice. 😃
Almost certainly since it happens for multiple objects in the same field.
So this is an example of a small fraction of images we've included to cross match morphologies from this sample with the original GZ sample.
Nice. Would be great for our #maths #alphabet
I'm not sure I'd call this an elliptical.... in the RC3 it was classified S? by the "experts", so even they didn't know what to make of it..
It's detected in HI - which means it has a lot of atomic hydrogen in it - the raw material for future star formation...
... and has been studies previously in a sample of starforming #blue #ellipticals. Clear dust lane in the centre in this image.
What an interesting object. A NED search suggests it's IC 2520 at z=0.04.
That's called a #bar across the centre of this galaxy. I personally think they are really interesting. 😃
It is still there - it just doesn't have that central red #artifact. I think this is just a bright star badly imaged unfortunately.
In fact a search on NED reveals it's Arp 148 which is a known merger and also has an actively accreting black hole (AGN) in there.
This looks to me like a #merger. A bit like the Cartwheel galaxy, but in a different orientation.
That is a beautiful example of a #barred #ring galaxy. And not a spiral arm in site. A lesson in orbital dynamics right there. 😃
That is interesting- a very low surface brightness object. My best guess is it's unrelated to the edge-on disc galaxy. Perhaps an #overlap?
Very nice #ring with #ansae at the end of the #bar (those dumbell shaped bits).
Wow! That galaxy is all #bar with some tiny #spiral arms. And definitely beautiful.
Thanks for sharing the Hubble Images Budgieye. 😃 That's great.
Looks like a beautiful #irregular galaxy to me.
I'm afraid I don't see what you mean. Might be too late at night! 😉 More description? Lines are usually artifacts....
Looks like a plausible minor #merger with the galaxy to the right. 😃
That's a stunning galaxy.... Like arfon said - staformation regions in the outer spirals showing up as the #blueclumps
Actually if you zoom out a lot I think you can faintly see it's the edge of a field where the background colour is subtly different.
Or see here: http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=358.57882216&dec=31.72040487
Wow! Good eyes! It's more obviously an image artifact (possibly a diffraction spike from somewhere) in the Skyserver image (follow "examine"
Wow - great tidal tail. That would be a nice one to model. And I see the blue #voorwerpje too. Bill will be pleased. 😃
I think I see material linking the two, so my best guess would be #merger. Need redshifts for sure - you can try NED to see if they exist.
To tell for sure we could look at line ratios (which indicate the hardness of the ionizing radiation), but an AGN would be unlikely.
I'd bet on irregular too - with the very large emission lines from very active star formation (typical in irregulars) rather than an AGN.
I just learned it's called an "M51 (Whirlpool) like" pair. You can see why. 😃
Very nice. This is NGC 3799 and 3800 which are a known pair (astronomers have measured redshifts for both of them at around 3300 km/s).
I think the bright dot to the upper right is probably a foreground star. Although I'm not completely sure.
They're star formation regions in the outer regions of this lovely #spiral galaxy.
Just do the best you can. 😃
Probably a #star. Might be in a bad imaging area too.
I think I can't spell. #toofaintoclassify
Or seriously, two disc galaxies approaching each other face on (and we see edge on). Neat orientation to simulate....
An equals sign, for a cosmic #maths #alphabet
Beautiful barred spiral.
It's a very bright star in the g-band (blue) filter.
Can I see an optical #jet coming out of this elliptical galaxy?
This is a part of the bigger galaxy to the left of the image.
Nice letter P (rotated slightly). #alphabet
What a lovely thin edge-on disc galaxy. Great dust lane too.
Probably a bunch of stars. 😃
Very nice example of ansae at the ends of the bar.
Yeah - it's very faint, so hard to tell much. Just have to do the best you can with these ones. 😃
Yeah - too bad it's so close to the edge of a field. That might be a fix we can make at some point.
I think it might be a poorly resolved disc with a bar (almost vertical).
That is a nice one. 😃
Might be a #star
Beautiful example of two #spirals #merging. Nice one. 😃
#star I think
Charle Messier would agree with you! 😉 I think it's an edge-on disc galaxy though.
That's an amazingly beautiful galaxy. And so neat that you can see the outer third arm. Thanks for pointing it out. 😃
I think it's a #star in a really funky part of SDSS imaging where the colours have gone a bit odd. So classify as star/artifact.
Another one for tofainttoclassify
It's just a smooth galaxy. We have buttons for that. 😃
Perhaps we should start a #toofaintoclassify group. That could be really useful information in pruning the sample list. 😃
Would be cool if that were true. Unfortunately this is an #artifact
Another #greenline #artifact
It's an image #artifact which only appears in the filter we display as green in these images.
Always just classify the middle one. If you want to comment on the others you can mention them in "something odd" at the end.
So it's could really be green because of the strong emission lines which fall in the r-band filter of SDSS.
In fact if you keep going through to NED (NASA Extragalactic Database) you can see it is a #planetarynebula cool!
So I wonder if there is only a good green (r-band) image there - hence the odd green look.
Oh that is odd. If you go into examine you can see it's near the edge of the SDSS survey (zoom out a bit on Sky server)
I think this is an #artifact (based on colour), but it's obviously extended too. Opinions?
Nice #bulgeless #edgeon #disc
An example of an #artifact (which only appears in the green filter). A satellite trail perhaps?
It's probably a foreground #star
It's a very faint low surface brightness galaxy (right in the middle, faintly green). I agree this is very hard to classify.
Looks like Alice's famous "Penguin Galaxy" to me..... (just rotated, and near the edge of a frame). Physically - it's an interacting galaxy.
Probably a foreground star.
Edge of field, and centred on a star...
My first pretty barred spiral in the new interface. 😃
Surprised this made it in here - this is very close to the Galactic plane. Not a galaxy.
