A massive asteroid slammed into Earth about 66 million years ago, causing the mass extinction of the dinosaurs. But dinosaurs weren't the only ones to disappear. Scientists have found that mollusks may have also vanished after this catastrophic event.
Asteroids and comets may not just have delivered water to Earth. It turns out that this delivery may be taking place in many other planetary systems, just like it happened on our own planet.
It turns out that the asteroid that slammed into Earth about 66 million years ago and killed off the dinosaurs probably rang our planet like a bell. The results were massive volcanic eruptions around the globe.
Scientists may have found out not only how asteroids formed, but also how our planet was created.
Where did the largest asteroid impacts occur on our planet? It turns out that Australia holds the record.
NASA's Dawn spacecraft is approaching its historical rendezvous with the dwarf planet Ceres. Now, it's returned new images captured on its approach, revealing new features of the dwarf planet.
The massive asteroid that buzzed Earth on Monday didn't come alone. Scientists working with NASA's Deep Space Network antenna found that the asteroid was so large that it had its own small moon.
You wouldn't think our planet experiences many close encounters from asteroids. Yet a new map shows exactly how often Earth's atmosphere is hit by small asteroids, called bolides.
It turns out that the asteroid Vesta may have a history of large impacts. Scientists have completed the first geological and tectonic map of the asteroid, revealing a bit more about its past.
Astronomers have discovered a new active asteroid within our solar system. Called 62412, the asteroid is located in the main asteroid belt between Mars and Jupiter, and is the very first comet-like objects seen in the Hygiea family of asteroids.
Scientists may have found out how Vesta became shaped like it is. Using computer models to simulate collisions on Vesta, scientists have found out how Vesta may have gotten the deep grooves that encircle its midsection.
NASA's Spitzer Space Telescope may have just spotted the remains of a collision between large asteroids. It's found an eruption of dust around a young star with particles that could eventually lead to the formation of planets.
