 Cardiff, UK (SPX) Nov 03, 2009 
A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by a Cardiff University scientist. The team has obtained extremely precise data about the early universe, using a telescope near the South Pole in the Antarctic. Their measurements of the cosmic microwave background - a faintly glowing relic of the hot, dense, young universe ... read more
Menlo Park CA (SPX) Nov 03, 2009Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA's Fermi Gamma-ray Space Telescope. Two so-called "starburst" galaxies, plus a satellite of our own Milky Way galaxy, represent a new category of gamma-ray-emitting objects detected both by Fermi and ground-based observatories. "Starburst galaxies have not been accessible in ... more

Washington DC (SPX) Nov 03, 2009Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. The stratospheric dust includes minute grains that likely formed inside stars that lived and died long before the birth of our Sun, as well as material from molecular clouds in interstellar space. ... more 
Boston MA (SPX) Nov 03, 2009Nearly 100 years ago, scientists detected the first signs of cosmic rays - subatomic particles (mostly protons) that zip through space at nearly the speed of light. The most energetic cosmic rays hit with the punch of a 98-mph fastball, even though they are smaller than an atom. Astronomers questioned what natural force could accelerate particles to such a speed. New evidence from the ... more  
Paris, France (ESA) Nov 03, 2009ESA is offering European students the opportunity to conduct hypergravity experiments, with a call for proposals for the 2010 'Spin Your Thesis!' programme. This programme will enable university students to carry out experiments in hypergravity by using the Large Diameter Centrifuge (LDC) in ESTEC, the Netherlands. The LDC allows samples to be exposed to acceleration forces of 1-20 ... more |

Paris (AFP) Oct 29, 2009It took 13 billion years to reach Earth, but astronomers have seen the light of an exploding mega-star that is the most distant object ever detected, two studies published Thursday reported. The stunning gamma-ray burst (GRB) was observed by two teams of researchers in April, and opens a window onto a poorly known period when the Universe was in its infancy. GRBs are the most violent ... more  
Paris, France (SPX) Oct 30, 2009The combination of images taken by three exceptional telescopes, the ESO Very Large Telescope on Cerro Paranal , the MPG/ESO 2.2-metre telescope at ESO's La Silla observatory and the NASA/ESA Hubble Space Telescope, has allowed the stunning Jewel Box star cluster to be seen in a whole new light. Star clusters are among the most visually alluring and astrophysically fascinating objects in ... more  
Paris, France (ESA) Oct 29, 2009Satellite operations for the CoRoT mission have been extended until 31 March 2013. The decision by the French Space Agency, CNES, and the mission partners, including ESA, was taken on 23 October at a specially convened meeting at the CNES Headquarters in Paris. Launched in December 2006, with a nominal lifetime of 3 years, CoRoT has steadily pursued its dual mission objectives of searching ... more |
