The latest update from NASA's Kepler space telescope — designed to spot distant exoplanets — adds more than 500 new possible planets to the fray. That's in addition to the 4,175 planets already found by Kepler.
And of those 500 new potential planets, scientists say, a dozen could be remarkably Earth-like. That means they're less than twice as large as Earth, are potentially rocky and are at the right distance from their host stars to harbor liquid water.
