Sixty-five million years ago, a meteorite careened into Earth, leaving a huge crater on the coast of the Yucatan Peninsula. The impact is likely responsible for killing off the most of the dinosaurs—along with 75 percent of all species on Earth. Scientists are now planning an expedition to drill into the…
Nearly 15% of all asteroids travel in pairs, yet very few impact craters on Earth have been identified as "doublets" — dual craters arising from sudden back-to-back impacts. But a new analysis has identified a potential candidate in Sweden, the product of a binary pair striking the Earth some 458 million years ago.
These objects are startlingly reminiscent of Star Trek's Federation insignia — but they're geological features inside a large crater on Mars. It's a phenomenon, says NASA, that also explains why migratory birds fly in a v-shaped formation.
NASA's Mars Orbiter has discovered a brand new impact crater on the Martian surface — and it's a beauty.
Earth's moon has been blasted by a lot of space rocks in its 4.5-billion-year history. While these impacts have left a near-uniform distribution of craters across our satellite's surface, planetary scientists have shown that one of its sides – the side that faces Earth – bears significantly larger scars than the…
Why? Because we never pass up the opportunity to sling Sean Connery puns. Also, this lunar ash hole is actually pretty cool.
