Meteorite made up of rare early solar system material

January 16, 2013 9:22 am | News | Comments

It looked like a fireball in the sky. It created a sonic boom. It vaporized upon entering the atmosphere. It's all of the above: The Sutter's Mill Meteorite had the force of 4 kilotons of TNT upon descent and spilled samples of itself over the towns of Columa and Lotus in northern California when it hit Earth last spring. And now a consortium of scientists has determined that the Sutter's Mill Meteorite is the most pristine sample yet collected of the rare Carbonaceous-Mighei chondrite class of meteorites.

Whew! Big asteroid no longer threat to Earth

January 11, 2013 10:31 am | by Seth Borenstein, AP Science Writer | News | Comments

About nine years ago, when astronomers first saw Apophis, they thought there was a 2.7% chance that it would smack into our planet. Later, they lowered the chances to an even more unlikely 1 in 250,000. Now it's never mind, they say, as the 1,060-foot wide rock will approach to within 20,000 miles.

Farthest supernova yet for measuring cosmic history

January 10, 2013 2:27 pm | News | Comments

In 2004 the Supernova Cosmology Project used the Hubble Space Telescope to find a tantalizing supernova that appeared to be almost 10 billion light-years distant. But Lawrence Berkeley National Laboratory scientists had to wait until a new camera was installed on the Hubble years later before they could confirm the candidate's identity and redshift as a Type Ia "standard candle." The spectrum and light curve of supernova SCP-0401 are now known with clarity; it is the supernova furthest back in time that can be used for precise measurements of the expansion history of the universe.

Curiosity's science team plans to get a closer look at it before proceeding to other nearby rocks.

Martian rock from Sahara desert unlike others

January 3, 2013 4:25 pm | by ALICIA CHANG - AP Science Writer - Associated Press | News | Comments

  Scientists are abuzz about a coal-colored rock from Mars that landed in the Sahara desert: A yearlong analysis revealed it's quite different from other Martian meteorites. Not only is it older than most, it also contains more water, tests showed. The baseball-size meteorite, estimated to be 2 billion years old, is strikingly similar to the volcanic rocks examined on the Martian surface by the NASA rovers Spirit and Opportunity, which found water-bearing minerals.

Just in time for the holidays, NASA's Cassini spacecraft, in orbit around Saturn for more than eight years now, has delivered another glorious, backlit view of the planet Saturn and its rings.On Oct. 17, 2012, during its 174th orbit around the gas giant, Cassini was deliberately positioned within Saturn's shadow, a perfect location from which to look in the direction of the sun and take a backlit view of the rings and the dark side of the planet.

Clays on Mars: More plentiful than expected

December 21, 2012 9:30 am | News | Comments

A new study indicates that clay minerals, rocks that usually form when water is present for long periods of time, cover a larger portion of Mars than previously thought.  In fact, the research team say clays were in some of the rocks studied by Opportunity when it landed at Eagle crater in 2004. But Opportunity doesn’t have the capability any longer to detect these clays, which were found using spectroscopic analysis from the Mars Reconnaissance Observer.
