    I don't know how to treat these images?

    I'm copying this from another of your posts, but the answer is the same

    First of all, always classify the object in the center of the image, even if it is the most boring one ! 😄

    And all the objects in this image are stars from our galaxy, so the classification would be : star/artifact !

    Happy hunting ! 😄

    Welcome to Galaxy Zoo, Magon!

    These are stars in our own galaxy, the Milky Way. However, the SDSS camera was having an 'off' night suffered a glitch (likely lost correct focus), and produced all these funny colored blobs. Thus, though they're #stars, they're also #artifacts, due to this being a #poorqualityimage.

    There's a thread, somewhere here in Talk, which explains all this, and also says that the Science Team has known about these bad fields for a long time, but for some reason they haven't yet removed them all, and so you'll occasionally still get one to classify.

    Happy hunting! 😃
