All You Need is a Meteorite

Astronomers have long thought that life moves through thesolar system on the backs of meteorites, meaning that lifeon Earth was "seeded" from another planet. New researchshows that it's not necessary for the actual microbes totravel through space. The fact that a meteorite impactbrings phosphorous to a planet may be enough.

Saved from the Dinosaur's Fate

A meteorite impact helped wipe out the dinosaurs 65 millionyears ago. Now satellites have discovered that anotherimpact the same size hit the Earth more recently, whenhumans were alive. It didn't end our species because it hitduring an ice age and sank into the Antarctic ice. Much morerecently, in England, a woman was hit by a meteorite...

Dangerous Asteroids Can be Made to Miss Us

The dinosaurs died when an asteroid hit the Earth, but we're determined not to. Astronomers say they're having success in finding every large asteroid that poses a threat to life on Earth. The next step will be to look for smaller objects that could cause localized destruction if they impacted the Earth. But once they find them, what can they...

Future Asteroid Will Cause Giant Tsunamis

Asteroid 1950 DA is heading our way and is due to hit the Earth on March 16, 2880. Since 70% of the Earth is covered with water, it will probably land in the ocean, causing huge tsunami waves to spread out from the impact and drown coastal areas. A computer simulation of an asteroid impact tsunami developed by California scientists shows waves...
