Meteorites,Comets and Asteroids

NASA's WISE spacecraft, scanning the entire sky at infrared wavelengths, has delivered new insights about distant cometary wanderers.

Scientists pursue research through observation, experimentation and modeling. They strive for all of these pieces to fit together, but sometimes finding the unexpected is even more exciting.

New research shows that large meteorite impacts can be followed by intense, long-lived, and explosive volcanic eruptions.

Massive landslides, similar to those found on Earth, are occurring on the asteroid Ceres.

Astronomers have revealed extraordinary details about a recently discovered far-flung member of our solar system.

Researchers suggest that Ceres' temporary atmosphere appears to be related to the behavior of the sun, rather than its proximity to the sun.

For at least a million years, an asteroid orbiting the "wrong" way around the sun has been playing a cosmic game of chicken with giant Jupiter.

The tilt of Ceres' rotation axis could be related to ice in shadowed regions, research from NASA's Dawn mission suggests.

Rosetta spacecraft documented growing fractures, collapsing cliffs and rolling boulders on the comet's surface.

The bright central area of Ceres' Occator Crater, known as Cerealia Facula, is approximately 30 million years younger than the crater in which it lies, according to a new study.
