AstroQuest is a citizen scientist research project designed in a gaming format. You are presented with an image of a galaxy, with a computer-generated overlay that identifies the light coming from that galaxy or from overlapping stars. Your job is to tell us if the computer got the overlay right or wrong. There are simple questions to help you make your decision. If it's right, mark as correct and you'll move to the next galaxy. If it's wrong, you can fix it using paint tools, and help us train the computer algorithm.
