Cassini Sees Saturn Stressing out Enceladus
Mar 20, 2012 08:44 AM E
Images from NASA's Cassini spacecraft have, for the first time, enabled scientists to correlate the spraying of jets of water vapor from fissures on Saturn's moon Enceladus with the way Saturn's gravity stretches and stresses the fissures. The result is among the Cassini findings presented today at the Lunar and Planetary Science Conference at The Woodlands, Texas.

'Gravity Is Climate' - 10 Years of Climate Research Satellites GRACE
Mar 19, 2012 16:01 PM E
For the first time, the melting of glaciers in Greenland could now be measured with high accuracy from space. Just in time for the tenth anniversary of the twin satellites GRACE (Gravity Recovery and Climate Experiment) a sharp image has surface, which also renders the spatial distribution of the glacial melt more precisely.

Geologic Map of Jupiter's Moon Io Details an Otherworldly Volcanic Surface
Mar 19, 2012 14:51 PM E
More than 400 years after Galileo's discovery of Io, the innermost of Jupiter's largest moons, a team of scientists led by Arizona State University (ASU) has produced the first complete global geologic map of the Jovian satellite. The map, published by the U. S. Geological Survey, depicts the characteristics and relative ages of some of t...

Sunspot Group 1429 and the Distant Sun
Mar 19, 2012 11:11 AM E
What's that on the Sun? Over the past two weeks, one of the most energetic sunspot regions of recent years crossed the face of the Sun. Active Region 1429, visible above as the group of dark spots on the Sun's upper right, blasted out several solar flares and coronal mass ejections since coming around the edge of the Sun almost a month ago.
