 | Professor's study of the Peruvian meteorite has yielded some interesting conclusions that could upend the conventional wisdom about the size and type of meteorites that can strike Earth. ...> Full Article |
 | A team of scientists and engineers has been selected by NASA to study design concepts for a radio telescope destined for the far side of the Moon. The telescope, at present dubbed the Dark Ages Lunar Interferometer (DALI), will peer into the last unexplored epoch in the early history of the universe. The team is led by the Naval Research Laboratory (NRL) and includes key contributions from Smithsonian Astrophysical Observatory (SAO) personnel. ...> Full Article |
Radio waves accelerate electrons within Jupiter's magnetic field in the same way as they do on Earth, according to new research published in Nature Physics this week. The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting Earth-orbiting satellites.

 | NASA released this week five years of data collected by the Wilkinson Microwave Anisotropy Probe (WMAP) that refines our understanding of the universe and its development. It is a treasure trove of information, including at least three major findings: ...> Full Article |
 | Scientists studying images from The University of Arizona-led High Resolution Imaging Experiment camera on NASA's Mars Reconnaissance Orbiter have discovered never-before-seen impact "megabreccia" and a possibly once-habitable ancient lake on Mars at a place called Holden crater. ...> Full Article |
 | Yesterday, members of the media visited ESA-ESTEC, the agency's European Research and Technology Centre, to see and learn about GIOVE-B, the second Galileo in-orbit validation satellite, before it is packed for shipping to the launch site. ...> Full Article |

 | Using two ESA spacecraft, planetary scientists are watching the atmospheres of Mars and Venus being stripped away into space. The simultaneous observations by Mars Express and Venus Express give scientists the data they need to investigate the evolution of the two planets' atmospheres. ...> Full Article |
 | Astrophysicists are having a heated debate over the wave structure of the Sun's Corona - a debate which may one day influence solar weather forecasting and the theory behind fusion reactors. ...> Full Article |
 | UK scientists and international colleagues using NASA's Cassini spacecraft which is currently orbiting Saturn have found evidence of material orbiting Rhea, Saturn's second largest moon. This finding is the first time rings may have been found around a moon. ...> Full Article |

 | Scientists have solved a 40-year-old puzzle by identifying the origin of the intense radio waves in the Earth's upper atmosphere that control the dynamics of the Van Allen radiation belts -- belts consisting of high-energy electrons that can damage satellites and spacecraft and pose a risk to astronauts performing activities outside their spacecraft. ...> Full Article |
 | Probing a glowing bubble of gas and dust encircling a dying star, NASA's Hubble Space Telescope reveals a wealth of previously unseen structures. ...> Full Article |
 | A NASA spacecraft in orbit around Mars has taken the first ever image of active avalanches near the Red Planet's north pole. The image shows tan clouds billowing away from the foot of a towering slope, where ice and dust have just cascaded down. ...> Full Article |
Modelling of the Earth's atmosphere has acquired economic importance due to its use in the prediction of ozone depletion and in measuring the impact of global warming. Now researchers have found that the rate at which electrons lose energy to carbon monoxide is greater than that to carbon dioxide at higher levels in the atmospheres of both Mars and Venus.

 | Diamonds may be rare on Earth, but surprisingly common in space -- and the super-sensitive infrared eyes of NASA's Spitzer Space Telescope are perfect for scouting them, say scientists at the NASA Ames Research Center in Moffett Field, Calif. ...> Full Article |
An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry "handedness" in a larger number than previously thought.

Interstellar space may be strewn with tiny whiskers of carbon, dimming the light of far-away objects. This discovery by scientists at the Carnegie Institution may have implications for the "dark energy" hypothesis, proposed a decade ago in part to explain the unexpected dimness of certain stellar explosions called Type1a supernovae.

 | Seeking an out-of-this-world travel destination? Outer space will rocket into reality as "the" getaway of this century, according to researchers at the University of Delaware and the University of Rome La Sapienza. In fact, the "final frontier" could begin showing up in travel guides by 2010, they predict. ...> Full Article |
