Biggest Crater in the Solar System Found on Mars
For a small planet, Mars sure knows how to go big. It's about half as large as Earth, but it's got the hugest volcano in the solar system in the Arizona-sized Olympus Mons and the grandest of all canyons in the 7 kilometer-deep Vallis Marineris. Now it can add its coolest, most-braggable title: the Biggest Impact Crater in the Solar System. In a new study out in Nature, scientists have shown that Mars was probably hit by an asteroid the size of the Moon sometime in its early history, which left a crater the size of the planet's entire northern hemisphere.

10 Scariest Asteroid Attacks on Earth: The Near Hits and Approaching Terrors
When it comes to comet impacts, the denizens of Earth may be living on borrowed time. Of course, comets are only about half the problem — there are plenty of asteroids whizzing around the inner solar system too — so we decided to have a look and see just how close modern society has come to destruction since 1900, and how close we're going to come over the next 100 years. The answers, provided in our nifty infographic, aren't reassuring. More »

Canada To Save Humans From Extinction
Well, it's about time. Asteroids hitting Earth has been a big problem for life this planet since forever, and at last governments around the world have been united in their inability to give a shit. And they did it without Gort the giant robot forcing them! Next year, the Canadian Space Agency will launch the Near Earth Object Surveillance Satellite (NEOSSat), the first space-borne asteroid hunting device ever made. More »
