 Tucson AZ (SPX) Oct 06, 2009 
A new analysis of Cassini observations of Jupiter shows that an "inverse energy cascade" mechanism could be supplying the energy that powers and maintains the intense jet streams that typically rip through Jupiter's atmosphere at the same speeds as much shorter-lived hurricanes and tornadoes do on Earth. Exactly what mechanism generates and perpetuates dozens of ferocious, relatively ... read more 
Sunspot NM (SPX) Oct 06, 2009In the pre-dawn hours of Oct. 9, as many people in New Mexico are still asleep or barely stirring, a momentous event will be happening in outer space that could help define future space travel. That event is a rocket smashing into a permanently shadowed crater on the moon, and New Mexico State University astronomers have a front-row seat on all the action. NMSU is taking part in a ... more

Huntsville AL (SPX) Oct 06, 2009Just imagine. A spaceship plunges out of the night sky, hits the ground and explodes. A plume of debris billows back into the heavens, leading your eye to a second ship in hot pursuit. Four minutes later, that one hits the ground, too. It's raining spaceships! Put on your hard hat and get ready for action, because on Friday, Oct. 9th, what you just imagined is really going to happen--and ... more 
Houston TX (SPX) Oct 06, 2009New global color maps reveal provocative patterns on the surfaces of Saturn's five innermost large icy satellites: Mimas, Enceladus, Tethys, Dione, and Rhea. These new maps are being presented in a report by Dr. Paul Schenk of Houston's Lunar and Planetary Institute at the AAS Division for Planetary Sciences meeting in Puerto Rico. The new maps reveal complex global color patterns on each ... more  
Munich, Germany (SPX) Oct 06, 2009Quite a few distant galaxies turn out to be cosmic delivery rooms. Large numbers of massive stars are born in the hearts of these starburst galaxies, and later explode as supernovae. In the remnants they leave behind, particles are accelerated to very high energies. Astrophysicists have now used the H.E.S.S. telescopes to make detailed measurements of the gamma rays from the NGC 253 galaxy ... more |

Berkeley CA (SPX) Oct 02, 2009BOSS, the Baryon Oscillation Spectroscopic Survey, is the most ambitious attempt yet to map the expansion history of the Universe using the technique known as baryon acoustic oscillation (BAO). A part of the Sloan Digital Sky Survey III (SDSS-III), BOSS achieved "first light" on the night of September 14-15, when it acquired data with an upgraded spectrographic system across the entire ... more 
Paris, France (ESA) Oct 01, 2009Newly released images, taken by the Hubble Space Telescope before the recent Servicing Mission, highlight the ongoing drama in two galaxies in the Virgo Cluster affected by a process known as 'ram pressure stripping', which can result in peculiar-looking galaxies. An extremely hot X-ray-emitting gas known as the intra-cluster medium lurks between galaxies within clusters. As galaxies move ... more  
Paris, France (ESA) Oct 01, 2009Following the launch and in-orbit testing of the most sophisticated gravity mission ever built, ESA's GOCE satellite is now in 'measurement mode', mapping tiny variations in Earth's gravity in unprecedented detail. The 'Gravity field and steady-state Ocean Circulation Explorer' (GOCE) satellite was launched on 17 March from northern Russia. The data now being received will lead to a better ... more |
