Explanation: NASA's revamped planet-hunting Kepler spacecraft has discovered more than 100 confirmed planets orbiting other stars. The spacecraft finds planets by the "transit method," noting the tiny brightness dips caused when a planet crosses its host star's face from Kepler's perspective. Kepler was launched in March 2009 tasked with determining how commonly Earth-like planets occur throughout the Milky Way galaxy. The mission has been incredibly successful, finding more than 1,000 alien worlds to date.
