 Pasadena CA (SPX) Nov 25, 2009 
In the first video showing the auroras above the northern latitudes of Saturn, Cassini has spotted the tallest known "northern lights" in the solar system, flickering in shape and brightness high above the ringed planet. The new video reveals changes in Saturn's aurora every few minutes, in high resolution, with three dimensions. The images show a previously unseen vertical profile to the ... read more 
Washington DC (SPX) Nov 25, 2009A new website will give everyone the chance to contribute to science by playing a 'cosmic slot machine' and compare images of colliding galaxies with millions of simulated images of galactic pile-ups. These collisions, which astronomers call 'galactic mergers', could be the key to finding out why the Universe contains the mix of galaxies it does - some with trailing spiral arms, others ... more

Boulder CO (SPX) Nov 25, 2009The first large black holes in the universe likely formed and grew deep inside gigantic, starlike cocoons that smothered their powerful X-ray radiation and prevented surrounding gases from being blown away, says a new study led by the University of Colorado at Boulder. The formation process involved two stages, said Mitchell Begelman, a professor and the chair of CU-Boulder's astrophysical ... more  
Sydney, Australia (SPX) Nov 25, 2009We've studied the human body in weightlessness for decades, and we now have a fairly good understanding of how it affects us. It's important to know this. Weightlessness, or microgravity, can seriously influence the health and performance of astronauts. One thing we don't properly understand, though, is the influence of partial gravity on the human ... more  
Huntsville AL (SPX) Nov 25, 2009Sometimes you really can believe your eyes. That's what NASA's STEREO (Solar Terrestrial Relations Observatory) spacecraft are telling researchers about a controversial phenomenon on the sun known as the "solar tsunami." Years ago, when solar physicists first witnessed a towering wave of hot plasma racing along the sun's surface, they doubted their senses. The scale of the thing was ... more |

Garching, Germany (SPX) Nov 24, 2009A bit of imagination on the part of a measuring instrument wouldn't be a bad thing. It could help to add data from areas where the instrument is unable to measure. However, it must do so constructively. In order to infer missing data in an astronomical measurement with more than just imagination, physicists at the Max Planck Institute for Astrophysics have formulated a theory of spatial ... more 
Pasadena CA (SPX) Nov 23, 2009When NASA's Cassini spacecraft began orbiting Saturn five years ago, a dozen highly-tuned science instruments set to work surveying, sniffing, analyzing and scrutinizing the Saturnian system. But Cassini recently revealed new data that appeared to overturn the decades-old belief that our solar system resembled a comet in shape as it moves through the interstellar medium (the matter between ... more 
Bonn, Germany (SPX) Nov 24, 2009Nowadays, solar eclipses are seen as a fascinating natural phenomenon. In earlier times, people viewed them instead as something threatening, since the Sun provides us with light and heat, without which life on Earth could not flourish. However, the cause of solar eclipses is now generally known: On its orbit around the Earth, the Moon passes between Earth and Sun, causing darkness lasting ... more |
