Engage! Astronomers need your assistance to detect space warps

Think you can find space warps? Astronomers have recruited thousands of citizen scientists to look for exoplanets, galaxies, moon craters and other cosmic curiosities and now they need your help to go after one of the weirdest phenomena in space-time: gravitational lenses.
The Space Warps website gives Internet users the opportunity to sift through telescope images and spot galaxies so massive they bend the light rays that pass near them, like a lens. The venture could help crack some of the secrets of dark matter, the mysterious cosmic stuff that is more plentiful than the ordinary matter we see around us.
"Not only do space warps act like lenses, magnifying the distant galaxies behind them, but we can also use the light they distort to weigh them, helping us to figure out how much dark matter they contain and how its distributed," Oxford University physicist Phil Marshall, one of the leaders of the Space Warps research team, said in Wednesday's kickoff announcement. "Gravitational lenses help us to answer all kinds of questions about galaxies, including how many very low-mass stars such as brown dwarfs which arent bright enough to detect directly in many observations are lurking in distant galaxies."
Space Warps is the latest gem in Zooniverse's constellation of online citizen-science ventures a constellation that also includes Planet Hunters, Galaxy Zoo, Moon Zoo and much, much more. The warp-hunting effort follows the model set by those other projects: Participants are given online training exercises to sharpen their lens-spotting skills, and then they're set loose to check sky survey images from the Canada-France-Hawaii Telescope.
