Apr 23, 2014Between 2000 and 2013, a network of sensors detected 26 explosions on Earth ranging in energy from 1-600 kilotons – all caused not by nuclear explosions, but rather by asteroid impacts. -
Apr 19, 2014Researchers have spotted the first signs of a potential 'exomoon.' It's presence cannot be confirmed because it was observed during a chance encounter of objects that will not occur again - but it is a step toward locating other moons around distant stars. -
Apr 18, 2014Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet. -
