May 21, 2014Scientists have found what they believe to be evidence of a powerful, ancient impact event in Canada’s Alberta province. -
May 17, 2014The target of ESA’s Rosetta mission has started to reveal its true personality as a comet, its dusty veil clearly developing over the past six weeks. -
Apr 30, 2014ISON Comet Photography Contest winners provide images from around the world -
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. -
Apr 15, 2014Scientists have identified a 3.26 billion-year-old impact crater that has a diameter up to two and a half times larger than the Chicxulub crater. -
Apr 1, 2014In its first months of operation, the Automated Planet Finder has found two new planetary systems, giving astronomers a taste of planetary riches to come. -
Mar 30, 2014Scientists have discovered that the remote asteroid Chariklo is surrounded by two dense and narrow rings. The origin of these rings remains a mystery, but they may be the result of a collision that created a disc of debris. -
Mar 19, 2014In another step forward in the search for habitable planets, a team of researchers announced that they have located a large swarm of comets and gas moving in a cloud around a nearby star.
