The research that brought to light the fossils of Ardipithecus ramidus, a hominid species that lived 4.4 million years ago in what is now Ethiopia, has topped Science's list of this year's most significant scientific breakthroughs. The monumental find predates "Lucy," -- previously the most ancient partial skeleton of a hominid on record -- by more than one million years, and it inches researchers ever-closer to the last common ancestor shared by humans and chimpanzees. http://www.physorg.com/news180282874.html Other Sciences Thu, 17 Dec 2009 14:35:25 EST news180282874 (PhysOrg.com) -- Adding cerium oxide to phosphate glass rather than the commonly used silicate glass may make glasses that block ultraviolet light and have increased radiation damage resistance while remaining colorless, according to Penn State researchers. These cerium-containing phosphate glasses have many commercial applications for use in windows, sunglasses and solar cells. http://www.physorg.com/news180098054.html Physics Tue, 15 Dec 2009 11:15:06 EST news180098054 (PhysOrg.com) -- Physicists at Queen Mary, University of London have begun looking deep into the Earth to study some of nature's weirdest particles; neutrinos. http://www.physorg.com/news180036183.html Physics Mon, 14 Dec 2009 18:50:02 EST news180036183 (PhysOrg.com) -- A galaxy located billions of light-years away is commanding the attention of NASA's Fermi Gamma-ray Space Telescope and astronomers around the globe. Thanks to a series of flares that began September 15, the galaxy is now the brightest source in the gamma-ray sky -- more than ten times brighter than it was in the summer. http://www.physorg.com/news179593672.html Space & Earth Wed, 09 Dec 2009 16:40:01 EST news179593672 (PhysOrg.com) -- A specialized camera on a telescope operated by U.K. astronomers from Liverpool has made the first measurement of magnetic fields in the afterglow of a gamma-ray burst (GRB). The result is reported in the Dec.10 issue of Nature magazine by the team of Liverpool John Moores University (LJMU) astronomers who built and operate the telescope and its unique scientific camera, named RINGO. http://www.physorg.com/news179593825.html Space & Earth Wed, 09 Dec 2009 15:11:24 EST news179593825 (PhysOrg.com) -- ESA's XMM-Newton X-ray observatory is celebrating its 10th anniversary. During its decade of operation, this remarkable space observatory has supplied new data for every aspect of astronomy. From our cosmic backyard to the further reaches of the Universe, XMM-Newton has changed the way we think of space. http://www.physorg.com/news179576027.html Space & Earth Wed, 09 Dec 2009 10:15:12 EST news179576027 (PhysOrg.com) -- A thin rain of charged particles continually bombards our atmosphere from outer space. The mysterious particles were first detected 100 years ago but until 10 years ago when a new type of telescope began to come online physicists weren't sure where the "cosmic rays" came from or how they were generated. They suspected the particles were accelerated by supernova shockwaves, but suspicions aren't proof. http://www.physorg.com/news179427195.html Space & Earth Mon, 07 Dec 2009 18:30:01 EST news179427195 New information about lightning-emitted X-rays, gamma rays and high-energy electrons during thunderstorms is prompting scientists to raise concerns about the potential for airline passengers and crews to be exposed to harmful levels of radiation. http://www.physorg.com/news179426300.html Space & Earth Mon, 07 Dec 2009 16:39:14 EST news179426300 (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
