11.08.11 - Scientists working with the 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have generated a short movie clip of asteroid 2005 YU55.
11.07.11 - NASA's Deep Space Network antenna in Goldstone, Calif. has captured new radar images of Asteroid 2005 YU55 passing close to Earth.
10.26.11 - A meteor is the most probable cause of a bright, colorful fireball witnessed by people in a wide swath of the southwestern United States.
10.25.11 - Latest indications are this relatively small comet has broken into even smaller, even less significant, chunks of dust and ice.
10.19.11 - NASA's Spitzer Space Telescope has detected signs of icy bodies raining down in an alien solar system.

10.10.11 - A new image from NASA's Dawn spacecraft shows a mountain three times as high as Mt. Everest, amidst the topography in the south polar region of the giant asteroid Vesta.
10.05.11 - Astronomers have found a new cosmic source for the same kind of water that appeared on Earth billions of years ago and created the oceans.
09.30.11 - NASA's Dawn spacecraft has completed a gentle spiral into its new science orbit for an even closer view of the giant asteroid Vesta.
09.29.11 - New observations by NASA's Wide-field Infrared Survey Explorer, or WISE, show there are significantly fewer near-Earth asteroids in the mid-size range than previously thought.

08.01.11 - NASA's Dawn spacecraft, the first ever to orbit an object in the main asteroid belt, is spiraling towards its first of four intensive science orbits.
07.28.11 - NASA's Dawn mission, in orbit around Vesta, captures a new image from a distance of 3,200 miles (5,200) kilometers from the giant asteroid.
07.21.11 - NASA's Dawn mission, in orbit around Vesta, captured the latest image from a distance of about 6,500 miles (10,500 kilometers) kilometers from the giant asteroid.
