This is a project called Galaxy Zoo where regular people can help scientists classify heavenly bodies by looking and labeling beautiful images (after a tutorial of course). Yay, citizen science!
“Galaxy Zoo: Hubble uses gorgeous imagery of hundreds of thousands of galaxies drawn from NASA’s Hubble Space Telescope archive. To understand how these galaxies, and our own, formed we need your help to classify them according to their shapes — a task at which your brain is better than even the most advanced computer. If you’re quick, you may even be the first person in history to see each of the galaxies you’re asked to classify.”
