(PhysOrg.com) -- NASA's Fermi Gamma-ray Space Telescope has made the first unambiguous detection of high-energy gamma-rays from an enigmatic binary system known as Cygnus X-3. The system pairs a hot, massive star with a compact object -- either a neutron star or a black hole -- that blasts twin radio-emitting jets of matter into space at more than half the speed of light. http://www.physorg.com/news178547547.html Space & Earth Fri, 27 Nov 2009 12:34:14 EST news178547547 In a partnership that exemplifies the One NASA theme, Goddard Space Flight Center engineers teamed up with the External Payloads Group at Johnson Space Center and the ISS Payload Ground Processing support team at Kennedy Space Center to create the ExPRESS Logistics Carrier (ELC) Project. http://www.physorg.com/news177337979.html Space & Earth Fri, 13 Nov 2009 13:40:02 EST news177337979 (PhysOrg.com) -- Astronomers have published the discovery of the farthest known object in the cosmos: a star that exploded when the universe was only 630 million years old -- only 4.6% of its current age. Light from this cataclysm had been traveling towards us for about 13 billion years, finally arriving here last April 23. http://www.physorg.com/news176733128.html Space & Earth Fri, 06 Nov 2009 12:50:01 EST news176733128 (PhysOrg.com) -- Research by Michigan State University scientists has shed new light on the properties of neutron stars, galactic oddities that are formed when a large star runs out of fuel and collapses. http://www.physorg.com/news176409161.html Physics Mon, 02 Nov 2009 18:33:35 EST news176409161 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. http://www.physorg.com/news176396829.html Space & Earth Mon, 02 Nov 2009 15:08:03 EST news176396829 (PhysOrg.com) -- An international collaboration that includes scientists from the University of Delaware's Bartol Research Institute in the Department of Physics and Astronomy has discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth. http://www.physorg.com/news176391501.html Space & Earth Mon, 02 Nov 2009 13:50:01 EST news176391501 (PhysOrg.com) -- The most distant object ever discovered is described in this week's edition of the science journal Nature. Two international teams of astronomers report their observations of a gamma-ray burst from a star that died when the Universe was 640 million years old, or less than 5 percent of its present age. http://www.physorg.com/news175969717.html Space & Earth Wed, 28 Oct 2009 17:30:09 EST news175969717 Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA's orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat finish may stoke the fires of debate among physicists over Einstein's special theory of relativity because one of the photons possessed a million times more energy than the other. http://www.physorg.com/news175965994.html Physics Wed, 28 Oct 2009 16:27:56 EST news175965994 During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. It captured more than one thousand discrete sources of gamma rays -- the highest-energy form of light. Capping these achievements was a measurement that provided rare experimental evidence about the very structure of space and time, unified as space-time in Einstein's theories. http://www.physorg.com/news175961092.html Space & Earth Wed, 28 Oct 2009 15:06:24 EST news175961092 (PhysOrg.com) -- 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). http://www.physorg.com/news175958564.html Space & Earth Wed, 28 Oct 2009 14:23:39 EST news175958564 Scientists are working on a new range of materials characterisation analysers and techniques that could help unlock the value contained in Australia's mineral deposits and improve processing performance, according to the October issue of Process. http://www.physorg.com/news174050326.html Space & Earth Tue, 06 Oct 2009 12:19:34 EST news174050326 From 10 to 17 October 2009, in France, Italy, Spain and many other countries, astroparticle physicists will meet the public to reveal some of the most exciting mysteries of the Universe. Within the first European Week of Astroparticle Physics, they will organise about 50 events all over Europe: open days, talks for the general public, exhibitions… http://www.physorg.com/news173713862.html Space & Earth Fri, 02 Oct 2009 15:30:01 EST news173713862 (PhysOrg.com) -- Quite a few distant galaxies turn out to be cosmic delivery rooms. Large numbers of massive stars are born in the hearts of these starburst galaxies, and later explode as supernovae. In the remnants they leave behind, particles are accelerated to very high energies. Astrophysicists have now used the H.E.S.S. telescopes to make detailed measurements of the gamma rays from the NGC 253 galaxy. As predicted, these high-energy rays originate from the region of maximum supernova activity close to the centre. (Science Express, September 2009) http://www.physorg.com/news173695636.html Space & Earth Fri, 02 Oct 2009 09:47:47 EST news173695636 (PhysOrg.com) -- Gamma-rays are the most energetic known form of electromagnetic radiation, with each gamma ray being at least one hundred thousand times more energetic than an optical light photon. The most potent gamma rays, the so-called VHE (very high energy) gamma rays, pack energies a billion times this, or even more. Astronomers think that VHE gamma rays are produced in the environment of the winds or jets of the compact, ultra-dense remnant ashes of massive stars left behind from supernova explosions. http://www.physorg.com/news173104115.html Space & Earth Fri, 25 Sep 2009 13:29:49 EST news173104115 (PhysOrg.com) -- Scientists are seeing sub-surface water ice that may be 99 percent pure halfway between the north pole and the equator on Mars, thanks to quick-turnaround observations from orbit of fresh meteorite impact craters on the planet. http://www.physorg.com/news173021371.html Space & Earth Thu, 24 Sep 2009 15:00:02 EST news173021371
