    Welcome to Galaxy Zoo! 😃

    It's important to always classify the object in the center, which in this case is a blue-white fuzzy ball, perhaps a bit out of round. Myself, I'd call it 'smooth' then 'in between'. I wouldn't say there's anything odd.

    However, there certainly is something odd! There are at least three sets of four green dots, each in the shape of a square; those are well-known artifacts of UKIDSS images (though I'm not sure if anyone has posted an explanation of how they are formed).

    Hope this helps, and happy classifying!

    Hi Anjali91 and welcome t the Zoo ! 😄

    First of, always classify the object in the center of the image. In this case it is a smooth and round (or intermediate) galaxy. The bright green dots (square) are optical artifacts;

    Happy Hunting !
