Galaxy Zoo Talk

New to Galaxy Zoo? Want Help? Read this!

  • vrooje by vrooje admin, scientist

    This is meant to help anyone who has questions about what to discuss on Galaxy Zoo Talk, and how to do it. There are some questions that come up pretty frequently, and some people have said they'd like to know what kinds of things they should be looking for. Below may not be an exhaustive list, but it's an attempt. If you have any questions please feel free to contact me or post a response.

    Tutorial

    We're currently updating the extended tutorial, so watch this space -- in the meantime I hope the information below will do.

    Classifying

    Always classify the central object. We ask many people to classify the same object, so we get a really good idea of how confident people were and therefore how easy to classify an object was. There's often no right answer, so just use your judgment and give us your best guess. And thank you!

    Weird Stuff

    If you came here to ask "what the heck is that?!" about something you've just seen, chances are it might be an artifact of some kind, or a normal object (like a star) that just looks weird. Here are examples of some common ones:

    olives in spaceolives in space


    AGZ0002k6n, AGZ0001wnp

    Something went weird with the focus/imaging: these are stars, believe it or not. #artifact



    star outside frame bright star just outside image


    AGZ0002j99, AGZ0002jvw

    There is a very bright star just outside this image and its light is spilling over into the frame. (Also, the image is partly cut off.) #artifact



    starstarstarstar


    AGZ00008ey, AGZ0003492, AGZ0003vrz, AGZ0001o4y


    Now the stars are all in the frame and look pretty weird. Some of these look weird because they're so bright. In general, the image creation is optimized to show galaxies in their best light, not stars, so stars often look a bit... well, like the above. #star #artifact

    Note it's quite common to see stars in front of galaxies, in which case that's a #foregroundstar.



    satellite trailsatellite trail


    AGZ00058eo, AGZ0003q65


    Satellites sometimes pass overhead as the telescope is observing and reflect light in a streak across the image as they pass by. They move quickly so their trails are always a single color: red, green, or blue. Sometimes you can classify the central galaxy, other times there is no central galaxy because the computer got a bit confused. (Also, the one without a galaxy in it has a #star off to the side.) #satellitetrail



    asteroid, foreground starasteroid


    AGZ00059k0, AGZ0003z60


    Asteroids also move across these images, albeit more slowly than satellites. So when each of the filters that make up the image colors takes data in succession, the asteroid looks like a multicolored stripe (or series of dots) across the image. You can usually classify the galaxy too, but this is interesting extra information. Note: the first example also has a #foregroundstar over the top of a lovely #edgeon galaxy. #asteroid



    edge of chipedge of chip


    AGZ000005o, AGZ0000001 <-- wait, really? 0000001? cool.


    Sometimes the very edges of a camera chip have bad pixels. Sometimes you can still classify the central galaxy. Other times, not. #edgeofchip #artifact



    Plus, there are lots of other weird things. Other examples (hover your mouse over the image to see my comments):
    bad trackingbad pixelsstar and bad zoombad sky backgroundartifactartifact


    AGZ0001u10, AGZ0000qos, AGZ0004fu5, AGZ0001tzy, AGZ00035f5, AGZ0001txq


    If you see something you've never seen before but that you suspect is weird, feel free to ask whether it's an artifact or not. If you'd like to see some other artifacts, check out these collections: CGZS0000gw, CGZS000119

    Now that you've seen this page you can just tag them using the hashtag system.

    Science Bonuses

    Galaxy Zoo volunteers are brilliant at finding weird and wonderful things we didn't expect. So we often want to keep track of objects with properties we don't ask about in the main classification questions. If you spot one of these kinds of objects you can help us by tagging it!

    Overlaps and Mergers

    Some galaxies that are close together on the sky are actual galaxy #mergers. Others are just coincidences, and sometimes the galaxies actually appear to #overlap on the sky. We can learn really interesting things about galaxies by looking at the ones that overlap! It can be difficult to decide whether two galaxies are interacting or are just overlapping, but if you suspect one or the other please do tag it! What do you think of these examples?


    overlapoverlapoverlapoverlap


    AGZ00054qy, AGZ0002baz, AGZ0002iue, AGZ0001us4


    Voorwerpjes

    Ever since the discovery of Hanny's Voorwerp we've been looking for more examples of ionized gas clouds in or near galaxies. They show up as brightly colored patches that don't really follow the rest of the shape of the galaxy, and we're on the hunt for more! Here are some examples of galaxies recently marked with the #voorwerpje tag: what do you think?

    voorwerpjevoorwerpjevoorwerpjevoorwerpje hubblevoorwerpjevoorwerpje

    AGZ0001xbb, AGZ0005ks2, AGZ0003g4y, AGZ00008gk, AGZ0002244, AGZ00059zp


    Bulgeless AGN

    We're looking for pure disk galaxies with no bulge but that host an AGN.

    ........."Wait, what's an AGN?"

    An Active Galactic Nucleus is the term for a supermassive black hole in its "on" state: it's actively growing, which means the region around it (which is very compact) is also radiating. It can be very bright. AGN are tricky to spot just by looking at an image, but often they look like stars (sometimes very bright stars) superimposed right over the middle of a galaxy. It's okay to mark it if you just suspect there might be one -- don't worry, we'll follow up and check for sure!

    Disk galaxies without bulges are of special interest because they have evolved without undergoing any of the processes that lead to the formation of bulges (including mergers). But those formation processes are the means by which supermassive black holes supposedly grow most of the time. So finding a growing black hole in a bulgeless galaxy is really interesting.

    If you spot one (and here are a few candidates), feel free to tag it as #bulgeless #AGN or even #bulgelessAGN:

    bulgeless AGNbulgeless AGNbulgelessbulgeless?

    AGZ0001gvd, AGZ000289a, AGZ00041mq, AGZ0003h9a


    And, of course, even if you aren't sure there's an AGN, you can always tag a #bulgeless galaxy.

    Other Stuff

    Perhaps the best part about Galaxy Zoo is that a new discovery is potentially just around the corner at any given moment. If you see something you don't see described here, just ask! Leave a comment on the object's page, or start a discussion about it. And if you have any other questions, please feel free to ask any member of the team, or a moderator. Feel free to send me a private message if you have questions you can't find the answer to elsewhere on Talk!

    And feel free to add to this too -- this project is always changing so I expect new science goals to be added and new artifacts discovered at any time.

    Cheers,

    -Brooke (vrooje)

    Anyone else having trouble with the electric blue type? The info. is great but wish I would have known all this before I started. For beginners, it's confusing where to leave a question and really assumes a high level of computer literacy (which is probably understandable given the topic of astronomy). Would help if I could blow up the pix I'm classifying. (see, it's probably super easy to do, I just don't know how!)

    Greetings all,

    I'm new to Zooniverse and I was curious if I find a galaxy can I name it like people do with stars? Like can I name it officially, so when people refer to the galaxy they use the name that I created?

    I'm relatively new to astronomy but I'm intrigued and eager to learn all that I can. The universe is unlimited and Earth is in the universe and I'm on Earth so that means I'm unlimited in the amount that I can learn right?!?!?!

    I'm kind of new on here and haven't marinated fully on the "Read this" info, so if anyone can answer my question about the naming thing it would be great! Thanks in advance 😃

    Posted

  • ElisabethB by ElisabethB moderator

    Hi 3Maceo3,
    Welcome to the Zoo. Hope you'll have a great time here.

    As for officially naming galaxies, sorry, that is not possible. The same goes for stars. But you can always name a galaxy, just for fun. 😄

    Happy Hunting !

    @ianbach, this is to give information on nebulae type of clouds http://www.sttff.net/ast/AST_nebulaclassification.html , but due to the nature of the pictures from SDSS and UKIDSS, you won't be able to see many nebula and gas clouds directly.

    I would also advise you have a quick look at these pages from SDSS if you're a starter 😉 http://skyserver.sdss.org/dr1/en/astro/stars/stars.asp

    Hi and welcome Jenszooni,

    Yes they are saved, over on Galaxy Zoo.

    If you look at the top of the screen, there is a 'Profile' hyperlink on the right. Click on that.
    Now click on the 'Favourites' hyperlink on the left hand side.

    Let me know if this works!

  • xantipa by xantipa

    Hi,

    as I have only 500 classifications I suppose here is the place to find answers to my beginner's questions:

    1. There is some erratic link about a quiz; where is it now; I wanted to do it in tha latest time but dissapeared.
    2. How many clicks should I collect in order to see some "Hubble Galaxies"?
    3. In the talk profile the only preferencies I can change is the Time format (absolute or relative). This is a bug or a feature?

    Thanks

    Posted

  • Capella05 by Capella05 moderator in response to xantipa's comment.

    Hi and welcome @xantipa 😃

    To answer your questions:

    1. Ignore the quiz pop-up - it is a retired 'feature' 😃
    2. The Hubble survey has been completed - since then we have done the UKIDSS and reverted back to SDSS. We have a exciting new survey coming up later this year - so watch the GZ blogs / social media / twitter or Talk for details 😄
    3. That is all you can currently configure - we will have a new version of talk launching next year, so it should be more customisable

    Hope this helps 😃.

    Hi NynkS2 😃

    Not having an image to look at, it sounds like you are describing foreground stars - sometimes there are problems with the filter on the telescope and we land up having some pretty spectacular artefacts to classify 😃

  • stefku by stefku

    Hi there

    I'm new and I've got some questions.

    1. Yesterday, I found a thread in the forum where I an ask newbee questions. I'm not able to find it anymore. The search is not working without login, but my login doesn't work. Anybody a hint what I'm doing wrong? I thought the login for the forum is similar to login to galaxyzoo.
    2. How do I distinguish stars from round galaxies? Maybe thats a topic for the help above on this thread.
    3. Skyserver already seems to know if an object is a star or a galaxy. Is this information right? If yes, why do I have to decide again?

    Thanks in advance 😃

    Posted

  • Capella05 by Capella05 moderator in response to stefku's comment.

    Hi and welcome @stefku 😃

    It is always good to have questions - I will do my best to answer them 😃

    1. The old forum is now an archive, you can still read all the old threads and posts, but you are unable to enter new ones. If you have a question related to a object, or even a general question post it here and someone will get back to you 😃
    2. Stars tend to be more cleanly defined than galaxies. To use a technical term - galaxies are more fuzzy 😃 Stars also have a few artifacts associated with them - these are caused by imaging 'errors' - they can have garish colours and diffraction spikes etc... If you have some examples you would like our opinion on - do post them!
    3. SkyServer is not always correct - they do try to be - but I have seen stars tagged as galaxies and visa versa. Always use your eyes first 😃

    Hoped this helped! 😃

    Posted

  • stefku by stefku in response to Capella05's comment.

    Thanks @Capella05, that helps 😃

    1. Unfortunately, I cannot discuss an object until I classified it. Or is there another possibility?

    Posted

  • Capella05 by Capella05 moderator in response to stefku's comment.

    Unfortunately not 😃 We want to get your opinion on the object. If you had a chance to discuss it, or read other volunteers opinions, the study would be biased.

  • Lyntessa.May_ by Lyntessa.May_ in response to vrooje's comment.

    In the last group of these galaxies the first three images look like they could all be the same galaxy from different angles. We only have our singular view from Earth and therefore I do not think they really are the same galaxy just that their shapes are similar. Looking at galaxies on end gives us a different view than looking at the top or a diagonal view of them. This is important in trying to determine what type of galaxy it is.

    Welcome, Marie! Don't be stressed. 😃 Each image is classified by many people, so mistakes aren't a problem. And when it's unclear what an object is, take your best guess! We've found that the cumulative effect of many people's guesses often helps us find the right answer.

    Again, welcome, and happy classifying! Hope to see you around Talk plenty!

    Is there any way to skip a galaxy?

    What's SDSS and how come I can't click it? Screenshot: http://screencast.com/t/tF2x5gGZLXJ

    Thank you 😃

    Posted

  • DZM by DZM admin

    Hi @Krystle!

    No, there's no way to skip a galaxy. We want people to classify whatever they see, even if it just means taking their best guess... and we want to make sure that people can't just skip until they find a cool one that they like. 😃 We need all of these classified, not just the cool-looking ones, and even the difficult ones! Don't worry if you're unsure; educated guessing is sometimes a core element of citizen science.

    SDSS refers to the Sloan Digital Sky Survey. I'm not 100% sure, but I think that the icon denotes that the image you're looking at came from the SDSS, and not the Hubble... ? It's just an indicator, not a link.

    Thanks for asking!!

    DZM is correct. In an earlier stage there were also images from Hubble so the icon changed according to where the image was coming from.

    Hi, My name is Jeremy. I am working to meld games with open source projects and education. For example, I am developing some software called GISZoo and GISCell, which in time will dovetail some features of Zooniverse with my project. I am here to explore how to infuse various Zooniverse projects into my game. I am also trying to convince Star Citizen developers that aspects of their game should include Zooniverse projects to enhance in-game play while helping to promote the goals of Zooniverse projects.

    Can someone offer a contact that I can use to discuss if it is possible to meld software between my project and Zooniverse?

    Budgieye is right. At one time there were also Hubble images thrown in the mix and that way people knew from which survey the image was.

    Yes; incidentally, I've told Jeremy in many places that he can reach out to me, though I haven't seen anything from him yet.

    And yes, for @mikorangester , these days we only have SDSS images, so every image will be marked SDSS. It's just a marker, not a button. Good question!

  • logic52 by logic52

    I have only just started to classify galaxies. I have found all the above questions and answers very helpful. I recently had an image that has six galaxies on it. I was only able to comment on one. How does one comment on multiple galaxies, or is the requirement to comment on the major one in the image?

    Posted

  • DZM by DZM admin in response to logic52's comment.

    Hi @logic52 -- welcome to Galaxy Zoo! Glad we're helping you out. 😃

    When there are multiple galaxies, you only want to classify the one in the very center. The rest are vestigial, although you could comment upon them if you wanted to.

    Hope this helps. Thanks for your effort!!

    Posted

  • Budgieye by Budgieye moderator

    More examples are needed on the classification page. A new classifier was confused about if an elliptical was clumpy with one lump.

    Clumpy galaxies need a lot of magnification to be seen. I can see a clumpy galaxy above the target galaxy. They are blue and have an irregular shape. The zoomed in images look more pixellated. The target galaxy in the center of the image is closer to us, so it appears larger and needs a zoomed out image. It looks like an edge-on galaxy, with a bulging nucleus. So I would classify as

    Features or disk, clumpy -no, Could this be a disk viewed edge-on? yes, rounded bulge, anything odd-no.

    I will suggest that there should be more examples on the classification page.

    Ellipticals are blobs from any direction, shaped like a rugby ball, American football, watermelon, avocado, .. take your pick. If you see them from one side, they are completely round, if you see them from the another, they are in-between. Ellipticals are never cigar shaped. If you see something long and thin with no detail, you are seeing an distant edge-on galaxy that has no nuclear bulge.

    Here is an example of an inbetween shaped elliptical.

    Having a nucleus doesn't count as detail.

    How do I get to look at Hubble images instead of SDSS?

    Posted

  • ElisabethB by ElisabethB moderator in response to KiranClarke's comment.

    Hi KiranClarke and welcome to the Zoo

    The Hubble images are all classified so we're, for the moment, back to the SDSS ones. But we are waiting for some new catalogues to classify.

    Hope this helps

    Happy hunting !

    @KiranClarke you might be interested in the "Galaxy Zoo: Bar Lengths" project. It's using Hubble images -- I think from CANDELS.

    I can barely use the net, much less twitter, which I suppose are the hash tags. So I will just put notes on discussions for someone else to pick up. If I just write the #etc note on it, will it work for you? where are a list of these #s and their descriptions for the uninitiated?

    How can we check on the comparable accuracy of our classifications if we are new to this?. I have moderate astro knowledge, but may have missed some terms.

  • ElisabethB by ElisabethB moderator in response to Ktrip's comment.

    Just check here in Talk ! 😄 And for some images there is no right or wrong. That is why they need us ! 😄

    Just answer the questions as well as you can !

    Happy hunting ! 😄

    Sorry, but there are no lists of #. Just look to the left and look at the posts that people post. I know this will sound really corny? But in fact, the classifications work out really good ! 😄

    Thanks for the info page. I am brand new to the site, I saw the talk on TED and had to check it out. I have no idea what I am doing so any advice would be great. Like, what do the terms next to each image mean. The RA. DEC, Redshift, log(Mstar), and Pbar? I am a complete newbie, help me out please. Point me at the right documents to read, or something.
    Much appreciated

    Could we get feedback on our classification somehow? Think it might enhance the validity (whatever it might mean in the classification context) of the classification outcome and to avoid being reliably wrong?

    Thanks.

    Posted

  • Budgieye by Budgieye moderator

    I will try to answer for the scientists. Nobody knows how they do on classification. It ruins the statistics gathered, if information is given out. A classifier gets better with practice, and his/her classifications get a higher reliability score, but no one ever finds out what is it.

    by klmasters ADMIN, SCIENTIST
    One way you can get some feedback if you wish to is to classify in a group (it can be a group of one person) and then use the Navigator tools to explore the galaxies you've classified in a group. This is a tool we've found to be popular with educators, but is available to all.

    Try it out here: http://www.galaxyzoo.org/#/navigator/home

    Just started classifying recently - enjoyable. Would it be possible to move the Examples screens and their enlargements to the right of the image of the galaxy being classified, or make them dragable to the right, to permit a more side-by-side comparison?
    Thanks.

  • ElisabethB by ElisabethB moderator in response to WGFinCO's comment.

    Sorry, I don't think these rearrangements are possible in this phase of the project. Maybe they will be taken into account when the project will move to the Panoptes environment.

    Thanks for participating ! 😄

    Thanks very much Brook
    A great help to my 11 yr old son and I who have just started. Enjoying the classifying of images together. Interestingly, he is far more decisive about what he sees immediately.
    We have alreay commented on 2 images, one which us a formless blue cloud and another a spiral galaxy with a detached cloud like part. Would appreciate comments from more experienced participants.
    Thx again

    Thanks so much for classifying!

    We have several really experienced classifiers (including our moderators) who comment when people ask questions, but sometimes it's hard to keep up. Sorry if we missed yours! 😃 But don't worry, your classifications will be useful no matter what.

    The "gamma" option doesn't work for me, as in it does exactly NOTHING. Have tried it in many pics with no luck. Am using a machine running Windows 10 version 1703 ( because the last version jacked up things, I am holding off on the most recent update)build 15063.726 and Firefox version 57.0 (again, holding off on updates since I HAAAAAATED the Quantum update. The Creator version was so much better)

    Some of my helpful hints for

    BEGINNERS

    There is no correct answer. If there are many different answers, it shows that this galaxy is difficult to classify, and that is information in itself.

    Please see the comments under your own. Hopefully the next version of Talk will not have them hidden low on your screen.
