- Sandia supercomputers offer new explanation of Tunguska disaster
12-18-2007 · EurekAlert!
The stunning amount of forest devastation at Tunguska a century ago in Siberia may have been caused by an asteroid only a fraction as large as those postulated in previously published estimates, Sandia supercomputer simulations suggest. Because there are more smaller asteroids than larger ones, the need to guard against such impacts may be greater than previously thought.

- When washed in sunlight, asteroids hit the spin cycle, Cornell researchers find
03-07-2007 · EurekAlert!
The sun is a cosmic spinmeister. Using the highly sensitive radar telescope at the Cornell University-managed Arecibo Observatory in Puerto Rico and Goldstone antenna in California, Cornell astronomers have confirmed a theory that sunlight and the asteroid's shape determine how an asteroid's rotation evolves. Their research is reported today in Science Express, the online edition of the journal Science.

- Amateurs and professionals combine observations to produce detailed picture of double asteroid
03-29-2007 · EurekAlert!
The main belt asteroid Antiope is among the few binary asteroids discovered in recent years, yet even through the Earth's largest telescopes it appears as merely two bright blobs orbiting one another. By harnessing the power of larger telescopes and the eagerness of amateurs with small instruments, UC Berkeley and Paris Observatory astronomers have constructed a detailed picture of the asteroid doublet: Two rubble piles twirling in a perpetual pas de deux.
