New Ring and Possible Moons Found at Saturn - Space.com  The Cassini spacecraft has detected two and possibly three new additions to the already full environment of Saturn, and scientists are puzzled over what they've seen. The first discovery is a wispy arc of ice and rocky material that sits between the A and F rings. The second is a tiny object skirting the outer edge of the F ring, which may be a moon but could just be a clump of rubble, scientists said this week. A third object is even more enigmatic. 

Grace Weighs In On Earth's Changing Climate - SpaceDaily  For the first time, scientists have demonstrated that precise measurements of Earth's changing gravity field can effectively monitor changes in the planet's climate and weather. Understanding how Earth's mass varies over time is an important component necessary to study changes in global sea level, polar ice mass, deep ocean currents, and depletion and recharge of continental aquifers. "Measurements of surface water in large, inaccessible river basins have been difficult to acquire, while underground aquifers and deep ocean currents have been nearly impossible to measure," said Dr. Byron Tapley, Grace principal investigator at the University of Texas Center for Space Research in Austin, Texas.    

Ice core reveals gentle start to last ice age  - Nature  Left:  The 3085 metre-long cylinder of ice records how our Earth has warmed and cooled over the last 123,000 years.  The last ice age began with gradual cooling rather than a dramatic climate crash, according to initial studies of the oldest Greenland ice core ever extracted. The core arms climate modellers with robust data to predict our own future. The 3-kilometre-long cylinder of ice records, in year-by-year detail, how Earth has warmed and cooled over the past 123,000 years. It also provides a unique snapshot of conditions about 115,000 years ago, when Earth slid into the most recent ice age. The international team of scientists on the North Greenland Ice Core Project (NGRIP) drilled the ice core between 2000 and 2003.
