News About Stellar Chemistry 09-NOV-09 en-us Boston MA (SPX) Nov 05, 2009 - Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object.]]> Edmonton, Canada (SPX) Nov 05, 2009 - University of Alberta physics professor Craig Heinke has solved a mystery that lies 11,000 light years beyond Earth. A supernova (or exploding star), 20 times heavier than our sun blasted apart, leaving behind a small core that has puzzled astronomers since its discovery in 1999.]]> Stanford, Calif. (UPI) Nov 4, 2009 - U.S. and Welsh researchers say they've obtained a detailed picture of the early universe using a telescope in the Antarctic.]]> 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.]]> Menlo Park CA (SPX) Nov 03, 2009 - Nearby 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.]]> Boston MA (SPX) Nov 03, 2009 - Nearly 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.]]> Paris (AFP) Oct 29, 2009 - It 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.]]> Greenbelt MD (SPX) Oct 29, 2009 - During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity.]]> Mount Pleasant MI (SPX) Oct 29, 2009 - Cobbling together 3000 individual photographs, a physicist has made a new high-resolution panoramic image of the full night sky, with the Milky Way galaxy as its centerpiece. Axel Mellinger, a professor at Central Michigan University, describes the process of making the panorama in the November issue of Publications of the Astronomical Society of the Pacific.]]> Charlottesville VA (SPX) Oct 29, 2009 - Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe - a gigantic stellar explosion known as a Gamma Ray Burst (GRB).]]>
