    What is the blue thing?

    It's difficult to say what the blue cloud is, but it can't be an artifact because it's visible in both SDSS and DECaLS.

    wow that object is 100% blue! another part to the left is mostly green, weird! VSTKIDS gri image; https://i.imgur.com/jRMAaSP.png

    Might I suggest putting it in 'Objects that need more research' thread 😃

    OK 😃 but come to think of it, objects sometimes look very blue in GAMA images e.g. asteroids.

    As you said visible in multiple surveys, and also extended shape 😃 AGZ000dx0d

    GAMA-KiDS has only 2 colours, so extreme blueness may be an artifact. Not so amazing in SDSS or DECaLS.

    But maybe a scientist should look at it, I'll contact one.

    GZ GAMA images are 2-coloured, but VSTKIDS is ugriz available on GAMA SWARP. If you look at those cutouts its only visible in g band (blue)

    Lovely link, the blue object is only in the g band. Either a strong emission in g, or an artifact.

    Strange that I can't see ANYTHING in SDSS g, only a bit of the greenish stuff. But blue certainly doesn't look like an artifact / transient

    The blue object is very dim in SkyServer, maybe that's why it's not visible in SDSS g, which is rather a grainy image.....

  • CeciliaB by CeciliaB

    ....Can't be an artifact / transient since it's visible in SDSS SkyServer, another survey.
