Cluster of galaxies
Is this a cluster or are they merging? Not sure what is happening in this one.
Welcome to Galaxy Zoo, hilscakes!
This is a #poorqualityimage, a kind of #artifact. The brightly colored blobs are stars in our own galaxy, the Milky Way. Something went horribly wrong, perhaps the telescope/camera was out of focus, perhaps the software pipeline which 'reduced' the data had an off night, perhaps ... whatever the reason, by marking these as #poorqualityimage, they can be removed quickly, and no zooite's time wasted by further classifying them.
Happy hunting! 😃
