This artist's concept depicts some of the planetary discoveries made by NASA's Kepler Space Telescope. Tuesday's announcement more than doubles the number of verified planets discovered by the Kepler mission.
This artist rendering shows Kepler-11, a sun-like star around which six planets orbit. A planet-hunting telescope is finding whole new worlds of possibilities in the search for alien life, including more than 50 potential planets that initially appear to be in habitable zones. The agency's chief scientist said Tuesday there will be "strong indications" of alien life within a decade.
SETI says that its Allen Telescope Array will be back online in September, thanks to funding secured from online donations. The array is seen here, adjacent to a cow pasture in Hat Creek, Calif.
