Some 3.26 billion years ago a giant rock between 50 and 200 times the size of the Chicxulub dino-killer smacked into our planet. The result of this impact may have churned up nutrients that gave a select few early microbes a boost.
A space rock that smacked into Earth 66 million years ago and devastated the ancient life living thereon took a remarkably circuitous route to get here, a new study has found.
A team of scientists have found that a single meteorite was likely responsible for creating billions of craters on the Martian surface.
Fine dust suspended in the atmosphere may have played a significant role in the extinction of dinosaurs after all.
The Deniliquin structure spans up to 520 kilometres in diameter. This exceeds the size of the near-300km- wide Vredefort impact structure in South Africa, which to date has been considered the world's largest.
NASA's scientist, James Garvin, thinks we might have been misreading traces of some of the more serious asteroid strikes that have occurred within the past million years. If he's right, the odds of being hit by something nasty could be higher.
