What's the worm like green thing on the left side of the image
I saw this worm like green thing on the left side of the image, next to the object to be classified, and wonder what it is.

Hi and welcome to Galaxy Zoo @yao_wu_23 😃
I love your description! The green worm is an optical artifact caused by imaging, so it is not real. We seem to see a lot of them in the DECaLS images - not too sure what caused this particular one though!
Thanks for your clicks and hope to see you around 😃
