Cassini Measures Tug Of EnceladusPasadena CA (JPL) Apr 27, 2010 NASA's Cassini spacecraft will be gliding low over Saturn's moon Enceladus for a gravity experiment designed to probe the moon's interior composition. The flyby, which will take Cassini through the water-rich plume flaring out from Enceladus's south polar region, will occur on April 27 Pacific time and April 28 UTC. At closest approach, Cassini will be flying about 100 kilometers (60 miles) above the moon's surface. Cassini's scientists plan to use the radio science instrument to measure the ... read more |

Orlando, Fla. (UPI) Apr 21, 2010 The U.S. space agency says data from its Spitzer Space Telescope revealed a distant planet that lacks methane in its atmosphere. "It's a big puzzle," said Kevin Stevenson, a planetary sciences graduate student at the University of Central Florida, lead author of a study focusing on the planet. "Models tell us the carbon in this planet should be in the form of methane. Theorists are goin ... more  
Paris, France (SPX) Apr 22, 2010The Cat's Paw Nebula, NGC 6334, is a huge stellar nursery, the birthplace of hundreds of massive stars. In a magnificent new ESO image taken with the Visible and Infrared Survey Telescope for Astronomy (VISTA) at the Paranal Observatory in Chile, the glowing gas and dust clouds obscuring the view are penetrated by infrared light and some of the Cat's hidden young stars are revealed. Toward ... more  
Berkeley CA (SPX) Apr 22, 2010The international Supernova Cosmology Project (SCP), based at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, has announced the Union2 compilation of hundreds of Type Ia supernovae, the largest collection ever of high-quality data from numerous surveys. Analysis of the new compilation significantly narrows the possible values that dark energy might take-but not enoug ... more |

NRL Researchers Study Galaxy MergersWashington DC (SPX) Apr 21, 2010 Scientists at the Naval Research Laboratory have solved a long-standing dilemma about the mass of infrared bright merging galaxies. Because galaxies are the largest directly observable objects in the universe, learning more about their formation is key to understanding how the universe works. Dr. Barry Rothberg and Dr. Jacqueline Fischer, both of the Infrared-Submillimeter Astrophysics and Techniques Section in the Remote Sensing Division, used new data from the 8-meter Gemini-South telescope in C ... read more |
