One of the great ongoing challenges of astrophysics, to find out how stars evolve and die, is to be tackled in an ambitious European research programme. This will involve studying in the laboratory over 25 critical nuclear reactions using low-energy stable beams of ions, in order to understand stellar evolution. "This programme will enhance the ongoing effort to understand the lifecycle of stars, together with the structure and processes of stellar evolution," said the workshop's convenor Sotirios Harissopulos from the National Centre of Scientific Research "Demokritos", Greece . "We also want to try and understand what happens when stars explode and how heavy elements are produced as a result."

 | Despite the incredible diversity of Saturn's icy moons, theirs is a story of great interaction. Some are pock-marked, some seemingly dirty, others pristine, one spongy, one two-faced, some still spewing with activity and some seeming to be captured from the far reaches of the solar system. Yet many of them have a common thread - black 'stuff' coating their surfaces. ...> Full Article |
 | NASA has selected a proposal by an MIT-led team to develop plans for an array of radio telescopes on the far side of the moon that would probe the earliest formation of the basic structures of the universe. The agency announced the selection and 18 others related to future observatories on Friday, Feb.15. ...> Full Article |

 | NASA's Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The double-ring pattern is caused by the complex bending of light from two distant galaxies strung directly behind a foreground massive galaxy, like three beads on a string. ...> Full Article |
 | A new 11-year cycle of heightened solar activity, bringing with it increased risks for power grids, critical military, civilian and airline communications, GPS signals and even cell phones and ATM transactions, showed signs it was on its way late Thursday when the cycle's first sunspot appeared in the sun's Northern Hemisphere, NOAA scientists said. ...> Full Article |
 | An international team of physicists, including University of Oregon scientists, has concluded that last February's intense burst of gamma rays possibly coming from the Andromeda Galaxy lacked a gravitational wave. That absence, they say, rules out an initial interpretation that the burst came from merging neutron stars or black holes within Andromeda. ...> Full Article |

 | The Sun is minimally active right now, but this quiet state of affairs won't last for long. Over the next few years, the number of solar flares and eruptions known as coronal mass ejections will increase until reaching solar maximum in 2011 or 2012. Such eruptions can impact Earth, disrupting satellites, communications, and even power grids. Some predict the next solar cycle will be the most intense in 50 years. As a result, scientists are striving to understand the mechanism behind solar eruptions in hopes of eventually being able to predict them in a space "weather forecast." ...> Full Article |

There is more to a grain of dust than meets the eye, at least for astronomers as they attempt to probe deeper into distant galaxies. Until now dust has been a nuisance because it has obscured galaxies, and the stars within them, by absorbing the radiation they emit. But more recently dust has started to present opportunities because it emits radiation itself as a consequence of being heated up by nearby stars. Aided by new observing instruments and sophisticated computer software, this radiation enables astronomers to reconstruct what lies behind the dust. Furthermore the dust itself plays a vital role in star formation within galaxies.

 | The Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) are two of the Milky Way's closest neighboring galaxies. A stunning sight in the southern hemisphere, they were named after Ferdinand Magellan, who explored those waters in the 16th century. For hundreds of years, these galaxies were considered satellites of the Milky Way, gravitationally bound to our home galaxy. New research by Gurtina Besla (Harvard-Smithsonian Center for Astrophysics) and her colleagues shows that the Magellanic Clouds are recent arrivals on their first visit to the Milky Way's neighborhood. ...> Full Article |
 | As the summer sun recedes, it makes way for the autumn stars sweeping in. Many belong to water constellations like Pisces, Capricornus, and Aquarius, which are now chasing the Milky Way westward. Late evenings are graced by a furiously brightening Mars, and approaching morning sees Venus soar to a lofty throne, there to preside until the break of day. ...> Full Article |

On 18 May 2007, the VIRGO interferometer began its first phase of scientific operation. This is a crucial step in the hunt for gravitational waves. VIRGO, which is the largest European (French-Italian) detector, joins company with the LIGO detectors in the US. This ultra-high-performance array of observation instruments will in particular be able to observe the coalescence of binary black holes in distant galaxies and provide information about the direction of the source. VIRGO is jointly run by CNRS and Italy's National Institute for Nuclear Physics (INFN).
