Hot Topic Solar System Meteorites, Comets and Asteroids
Asteroid Riddling
Topic: Meteorites, Comets and Asteroids
University of Arizona and Japanese scientists are convinced that evidence at last settles decades-long arguments about what objects bombarded the early inner solar system in a cataclysm 3.9 billion years ago.

Comet Cookbook
Topic: Meteorites, Comets and Asteroids
When Deep Impact smashed into comet Tempel 1 on July 4, 2005, it released the ingredients of our solar system's primordial "soup." Now, astronomers using data from NASA's Spitzer Space Telescope and Deep Impact have analyzed that soup and begun to come up with a recipe for what makes planets, comets and other bodies in our solar system.

Snowball Ceres?
Topic: Meteorites, Comets and Asteroids
Observations of 1 Ceres, the largest known asteroid, have revealed that the object may be a "mini planet," and may contain large amounts of pure water ice beneath its surface.

Painting Comets
Topic: Meteorites, Comets and Asteroids
Painting by the numbers is a good description of how scientists create pictures of everything from atoms in our bodies to asteroids and comets in our solar system. Researchers involved in NASA's Deep Impact mission have been doing this kind of work since the mission's July 4th collision with comet Tempel 1.

Nonlinear Solar System Evolution
Topic: Meteorites, Comets and Asteroids
Unexpectedly young material found in meteorites may break open current theory on the earliest events of the solar system.

2029 A Near Miss Odyssey
Topic: Meteorites, Comets and Asteroids
A University of Michigan-led research team has discovered that for the first time in history, scientists will be able to observe how the Earth's gravity will disrupt a massive asteroid's spin.

Triple A
Topic: Meteorites, Comets and Asteroids
One of the thousands of asteroids orbiting the sun has been found to have a mini planetary system of its own.

A Comet's Only Cameraman
Topic: Meteorites, Comets and Asteroids
No one knew what to expect from the Deep Impact collision between a ballistic spaceprobe and a comet. But scientists sat down with digital effects specialist, Dan Maas, to take a guess. As it turns out, both Maas and the scientists got it right in a spectacular visualization of what it might be like to broadside a comet.

Craters or Cradles?
Topic: Meteorites, Comets and Asteroids
Meteor impacts are generally regarded as monstrous killers and one of the causes of mass extinctions throughout the history of life. But there is a chance the heavy bombardment of Earth by meteors during the planet's youth actually spurred early life on our planet, say Canadian geologists.

Tempel's New Tail
Topic: Meteorites, Comets and Asteroids
Astronomers using the Palomar Observatory's 200-inch Hale Telescope have been amazed by comet Tempel 1's behavior during and after its collision with the Deep Impact space probe.
