The first direct evidence of the so-called YORP effect shows that heat from the sun can speed up or slow down an asteroid's spin, according to a trio of new studies.

Scientists expect to detect a lot more asteroid threats with new technology, but it's still not clear what anyone will do about them. Randy Dotinga reports from the AAAS meeting in San Francisco.

These Hubble Space Telescope images of Vesta and Ceres show two of the most massive asteroids in the asteroid belt, a region between Mars and Jupiter. The images are helping astronomers plan for the Dawn spacecraftâs tour of these hefty asteroids.

The chance of a football field-sized asteroid plowing into Mars next month has been increased to 4 percent, scientists said Friday after analyzing archival data.

Astronomers have found plenty of double, or binary asteroids. Triples are known to exist, too (the first triple was found in 2005).

LOS ANGELES - There&#39;s a 1-in-300 chance that a recently discovered asteroid, believed to be about 1,300 feet long, could hit Earth in 2029, a NASA scientist said Thursday, but he added that the perceived risk probably will be eliminated once astronomers

A MASSIVE asteroid heading for Earth has a 1-in-300 chance of smashing into the planet in 2029, say boffins. The space rock is believed to be more than 1,300ft long and was only rediscovered

Einstein was right -- again.  Satellites that have been pulled slightly off their orbits show  that the Earth is indeed twisting the fabric of space-time as  it rotates, scientists said on Thursday.

Astronomers  have pieced together what  appears to be the first direct evidence that solar storms can wreak  havoc with comets, destroying the ion tails of icy wanderers&nbsp;in a collision  of highly charged particles.&nbsp;

Planets form more violently than once thought, and many solar systems are strewn with dust from collisions like a blast that may have created Earth&#39;s moon, according to new findings.

For the very first time, astronomers have witnessed the speeding up of an asteroid's rotation, and have shown that it is due to a theoretical effect predicted but never seen before.

Scientists tracking an asteroid approaching Mars say that an impact with the Red Planet has become less likely. Refined estimates of the asteroid's orbit were made using new observations from a telescope at the Calar Alto Observatory in Spain, according to the Near-Earth Object Program at NASA's Jet Propulsion Laboratory.

There have been a couple of movies recently depicting the impending collision of an asteroid with Earth. It might not be sci-fi anymore.
