SDO Observes Massive Eruption And Scorching RainHuntsville AL (SPX) Apr 28, 2010 Just last week, scientists working with NASA's new Solar Dynamics Observatory (SDO) released the most astonishing movies of the sun anyone had ever seen. Now, they're doing it again. "SDO has just observed a massive eruption on the sun-one of the biggest in years," says Lika Guhathakurta of NASA headquarters in Washington DC. "The footage is not only dramatic, but also could solve a longstanding mystery of solar physics." Karel Schrijver of Lockheed Martin's Solar and Astrophysics Lab is lea ... read more |

Tokyo, Japan (SPX) Apr 23, 2010Observations with Subaru Telescope's Prime Focus Camera (Suprime-Cam) have revealed an extended structure of the spiral galaxy Messier 81 (M81) that may hold a key to understanding the formation of galaxies. This structure could be M81's halo. Until now, ground-based telescopes have only observed individual stars in the haloes around the Milky Way and Andromeda Galaxies. Differences in M81's ext ... more  
Moffett Field CA (SPX) Apr 23, 2010A new study in the journal Icarus provides the latest round-up of the number of impact craters found on Saturn's moon Titan. Between 2004 and December 2007, Cassini had surveyed 22 percent of Titan's surface. Scientists analyzed images taken by the spacecraft's high-resolution Radar Mapper instrument, and found 49 impact craters. "Impact craters are created on every planet because of ... more  
Pasadena CA (SPX) Apr 22, 2010NASA's Spitzer Space Telescope has discovered something odd about a distant planet - it lacks methane, an ingredient common to many of the planets in our solar system. "It's a big puzzle," said Kevin Stevenson, a planetary sciences graduate student at the University of Central Florida in Orlando, lead author of a study appearing tomorrow, April 22 in the journal Nature. "Models tell us tha ... more |

Searching For Dark Energy With The Whole World's Supernova DatasetBerkeley CA (SPX) Apr 22, 2010 The 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 enough to decide among fundamentally different theories of its nature. "We've used the world's best-yet datas ... read more |
