This intriguing looking image from Galaxy Zoo is actually the comet C/2001 RX14! The appearance of the nucleus as red, green and blue spots is caused by the fact that the images in Galaxy Zoo are composed of of multiple pictures taken in different colours one after the other. So as the comet moves it shows up at a slightly different place and as a different colour in each shot. See what you can discover today at www.galaxyzoo.org
