On Thursday (April 17), NASA announced the historic discovery of Kepler-186f, an Earth-size alien planet 490 light-years from our own world that is located inside the habitable zone of its star. See Space.com's complete coverage of the Kepler-186f find.
18 April 2014, 06:01 AM ET
The discovery of Kepler-186f still falls short of the ultimate prize in exoplanet science: a true "alien Earth." But the first such world may lurk in the data already gathered by NASA's Kepler space telescope, just waiting to be pulled out.
