With its “bombing” of the moon early Friday, NASA’s LCROSS mission may beat a telltale signature of water out of a shadowy crater—and all you may need to see it is a good backyard telescope.
LCROSS (Lunar Crater Observation and Sensing Satellite) and its rocket will begin slamming into the South Pole just after 4:30 a.m. PT.
About 1,100 years ago a space rock the size of a big tree stump slammed into western Canada, carving an amphitheater-like crater into the ground and littering it with meteorites, a new study found.
A meteor zipped across the U.S. Pacific Northwest sky early Tuesday morning before exploding, possibly littering eastern Oregon with marble- to basketball-size space rocks, an expert says.
It is almost certain that Earth will be hit by an asteroid large enough to exterminate a large percentage of our planet’s life, including possibly over a billion people, according to researchers. But as such cataclysmic collisions occur on average only once in a million years or so, are they really worth worrying about?
At some point in the geological future a large chunk of rock and ice will smack into Earth and destroy life as we know it. This is a cold, sober, scientific fact, according to Andrea Milani, a researcher at the University of Pisa in Italy.
