Researchers Say Asteroid Has 1 in 1,000 Chance of Hitting Earth in 2182
Asteroid trackers from Spain have upgraded the chance that asteroid 1999 RQ36 has a one-in-a-thousand chance of impacting the Earth in the year 2182. Previous estimates gave a 1 in 1,400 chance that this asteroid could strike Earth sometime between 2169 and 2199. Currently, however, NASA's Near Earth Object website gives between a 1 in [...]

Rosetta Meets Asteroid Lutetia
Over the weekend, the Rosetta spacecraft flew by asteroid Lutetia, returning the first close up images of this battered, cratered body. By all accounts, the flyby was a spectacular success with Rosetta performing faultlessly. Closest approach took place at 16:10 GMT on July 10, at a distance of 3,162 km (1964 miles). The images show [...]

Fully Functional Pan-STARRS is now Panning for Stars, Asteroids and Comets
There's a new eye on the skies on the lookout for 'killer' asteroids and comets. The first Pan-STARRS (Panoramic Survey Telescope & Rapid Response System) telescope, PS1, is fully operational, ready to map large portions of the sky nightly, making it an efficient sleuth for not just potential incoming space rocks, but also supernovae [...]

WISE Covers the Heart and Soul of Infrared Astronomy
In about six months' time, NASA's WISE mission, the Wide-field Infrared Survey Explorer, has captured almost a million images, covering about three-quarters, or 30,000 square degrees, of the sky. At the 216th American Astronomical Society meeting today, astronomers released a new mosaic of two bubbling clouds in space, known as the Heart [...]

WISE Pictures the Tadpole Nebula with a String of Pearls
The Tadpole nebula is looking very stylish in this new infrared image from the WISE spacecraft, NASA's Wide-field Infrared Survey Explorer. An asteroid appears like a string of pearls — seen as a line of yellow-green dots in the boxes near center — in this stitched together mosaic. The Tadpole is a star-forming [...]

Possible Destination? Researchers Find Water Ice and Organics on Asteroid
We usually think of asteroids as dark, dry, lifeless chunks of rock, just like the image of Asteroid Itokawa, above. But some asteroids may be more like "minor planets" after all. Researchers have found evidence on one asteroid – 24 Themis – of water ice and organic materials. This discovery is exciting [...]
