The building blocks of our planet may have been the source of water on Earth rather than comets or asteroids from faraway, researchers report.

Bright spots on the dwarf planet Ceres point to briny resevoirs below its surface, researchers say.

Tiny meteoroids on a far off asteroid could explain how we got both water and "stardust" on Earth.

Rockfalls on the moon leave their mark on the surface. A map of 136,610 rockfalls indicates that asteroid impacts are a likely cause.

Simulations may solve the mystery of why some asteroids like Bennu have a "spinning top" shape. The work points to the origins of these kinds of asteroids.

"Such high temperatures would completely melt an automobile in less than a minute."

Like a real life version of the game Asteroids, the majority of stars will become so luminous that their light causes asteroids to break into smaller bits.

Volcanoes had nothing to do with K-Pg, the mass extinction event in which dinosaurs perished, researchers say. That was all an asteroid's doing.

Could icy Hoth really exist? How about the iconic double suns of Tatooine? Experts on planetary formation, processes, and habitability discuss the science of Star Wars.

After several months evaluating data from four candidate sites on the asteroid Bennu, scientists have finally identified the best sample collection spot.
