A brilliant bright light seen streaking over the Southwestern sky Wednesday night was most likely a fragment of an asteroid.

NASA's Dawn spacecraft on Saturday became the first probe ever to enter orbit around an object in the main asteroid belt between Mars and Jupiter.

NASA says a newly discovered asteroid will have a close encounter with Earth today, but there's no need to worry.

The chemical building blocks that make life possible on Earth may have aged to perfection in asteroids, according to a new study.

A NASA spacecraft will reach out and touch an asteroid and send pieces back to Earth.

Mark your calendars for an impressive and upcoming flyby of an asteroid that’s one of the larger potentially perilous space rocks in the heavens – in terms of smacking the Earth in the future.

Jupiter and Mars aren't the only recent impact victims in our solar system. In two talks today at the Division for Planetary Sciences in Pasadena, California, astronomers report that a small asteroid located in the inner asteroid belt between those two planets took a major hit early last year.

A small asteroid passed within the moon's distance from the Earth on Wednesday morning, and another will do likewise later in the day, space watchers say.

NASA may appear to have its pick of thousands of known asteroids for a manned mission, but only two are good targets within the next 20 years. An asteroid mission requires a large-enough destination that astronauts could reach within a few months of launch from Earth, says Lindley Johnson, head of NASA's Near-Earth Object program in Washington. Other limits to such an ambitious undertaking include the viewing range of ground-based telescopes.
