02.15.13 - Small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15. There is no chance that the asteroid might be on a collision course with Earth.
02.07.13 - According to NASA's Near Earth Object program, there are more than 1,300 potentially hazardous asteroids that have a very small chance of hitting us someday because their orbits come close to Earth's orbit. The main difficulty is obtaining sufficient observations to predict their orbits with enough certainty to find out if any of them might actually hit us at some point.
02.05.13 - NASA's Deep Impact spacecraft has acquired its first images of comet C/2012 S1 (ISON).
02.04.13 - NASA will hold a media teleconference at 11 a.m. PST (2 p.m. EST), on Thursday, Feb. 7, to discuss an asteroid, 150 feet (45 meters) in diameter, that will pass close, but safely, by Earth on Feb. 15.
02.01.13 - A small asteroid named 2012 DA14 will safely fly past Earth's outer ring of satellites on February 15.
01.10.13 - NASA scientists at the agency's Jet Propulsion Laboratory in Pasadena, Calif., effectively have ruled out the possibility the asteroid Aphophis will impact Earth during a close flyby in 2036.
01.09.13 - Scientists using the Herschel Space Observatory made new observations of asteroid Apophis as it approached Earth this past weekend.
01.03.13 - A new study of images from NASA's Dawn mission examines remarkable, dark-as-coal material that speckles the surface of the giant asteroid Vesta.
12.14.12 - Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have generated a series of radar data images of a three-mile-long (4.8-kilometer) asteroid that made its closest approach to Earth on Dec. 12, 2012.
11.26.12 - Images of asteroid 2007 PA8 have been generated with data collected by NASA's Goldstone Solar System Radar.
11.05.12 - Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have obtained several radar images depicting near-Earth asteroid 2007 PA8.
11.02.12 - Comet 168P/Hergenrother is breaking up, right before our very eyes.
10.31.12 - Like a Hollywood starlet constantly retouching her makeup, the giant asteroid Vesta is constantly stirring its outermost layer to present a young face.
10.12.12 - A team of scientists from JPL needed some space. When a large fireball turned night into day over Battle Mountain, Nev. they knew they had their chance.
09.26.12 - Data from NASA's Dawn spacecraft suggest troughs sculpted around Vesta's middle are likely dropped blocks of terrain bounded by faults.
09.26.12 - Observations by NASA’s Dawn mission suggest that hydrated minerals were delivered to Vesta in a radically different way than how they were deposited on the moon.
09.20.12 - NASA's Dawn spacecraft has revealed that the giant asteroid Vesta has its own version of ring around the collar.
09.11.12 - NASA's Dawn mission is releasing two parting views of the giant asteroid Vesta, using images that were among the last taken by the spacecraft as it departed its companion for the last year.
09.05.12 - Mission controllers have confirmed that Dawn has left Vesta.
08.30.12 - NASA's Dawn spacecraft is on track to become the first probe to orbit and study two distant solar system destinations, to help scientists answer questions about the formation of our solar system.
