Astronomer Chris Lintott explains how you could help astronomers sort through galaxies, explore the surface of Mars, or even discover a planet. This is the story of the Zooniverse, which has enlisted more than two million people in the search for cosmic truth. Using stories drawn from contemporary research, this talk describes their discoveries - including the most mysterious star in the Milky Way - and argues that the search for the truly unusual could rely on you. The talk includes at least one picture of penguins.
