After being crippled by a mechanical malfunction, NASA’s planet-hunting Kepler spacecraft is back in action and has found a slew of planets orbiting other stars.
Called K2, the revamped mission has already found more than 100 confirmed planets, the University of Arizona’s Ian Crossfield announced Tuesday at a conference of the American Astronomical Society.
