(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) -- 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) -- 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 In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet. The galaxy, known as M31 in the constellation Andromeda, is the largest and closest spiral galaxy to our own. http://www.physorg.com/news172325981.html Space & Earth Wed, 16 Sep 2009 13:30:03 EST news172325981 Since its launch in 2004, NASA's Swift has detected more than 430 gamma-ray bursts. Roughly half of them are "dark" bursts that emit little or no visible light. Dense knots of dust in otherwise normal galaxies dim the light of a dark gamma-ray burst (center). The dust absorbs most or all of a burst's visible light but not higher-energy X-rays and gamma rays. Credit NASA/Swift/Aurore Simonnet Gamma-ray bursts are the universe's biggest explosions, capable of producing so much light that ground-based telescopes easily detect it billions of light-years away. Yet, for more than a decade, astronomers have puzzled over the nature of so-called dark bursts, which produce gamma rays and X-rays but little or no visible light. They make up roughly half of the bursts detected by NASA's Swift satellite since its 2004 launch. http://www.physorg.com/news163682108.html Space & Earth Mon, 08 Jun 2009 12:15:27 EST news163682108 (PhysOrg.com) -- NASA's Swift satellite and an international team of astronomers have found a gamma-ray burst from a star that died when the universe was only 630 million years old, or less than five percent of its present age. The event, dubbed GRB 090423, is the most distant cosmic explosion ever seen. http://www.physorg.com/news160143442.html Space & Earth Tue, 28 Apr 2009 13:17:50 EST news160143442 A montage of comet images made using NASA's Swift spacecraft illustrates just how different three comets can be. The images, including a never-released image of Comet 8P/Tuttle, were shown during a webcast called "Around the World in 80 Telescopes" Organized by the European Southern Observatory headquartered in Garching, Germany. http://www.physorg.com/news159812197.html Space & Earth Fri, 24 Apr 2009 17:18:42 EST news159812197 A montage of comet images made using NASA`s Swift spacecraft illustrates just how different three comets can be. The images, including a never-released image of Comet 8P/Tuttle, were shown today during a live, 24-hour video webcast called `Around the World in 80 Telescopes.` Organized by the European Southern Observatory headquartered in Garching, Germany, the webcast is part of the 100 Hours of Astronomy project, a worldwide celebration of astronomy running through April 5. http://www.physorg.com/news158250873.html Space & Earth Mon, 06 Apr 2009 15:35:06 EST news158250873 (PhysOrg.com) -- UK astronomers, using a telescope aboard the NASA Swift Satellite, have captured information from the early stages of a gamma ray burst - the most violent and luminous explosions occurring in the Universe since the Big Bang. The work was published on Friday 27th February in the Monthly Notices of the Royal Astronomical Society. http://www.physorg.com/news155223470.html Space & Earth Mon, 02 Mar 2009 13:38:28 EST news155223470 (PhysOrg.com) -- Space scientists from the University of Leicester are keeping a close eye on a ‘green comet` fast approaching the Earth - reaching its nearest point to us on February 24. http://www.physorg.com/news154342687.html Space & Earth Fri, 20 Feb 2009 08:59:08 EST news154342687 (PhysOrg.com) -- Astronomers using NASA's Swift satellite and Fermi Gamma-ray Space Telescope are seeing frequent blasts from a stellar remnant 30,000 light-years away. The high-energy fireworks arise from a rare type of neutron star known as a soft-gamma-ray repeater. Such objects unpredictably send out a series of X-ray and gamma-ray flares. http://www.physorg.com/news153492807.html Space & Earth Tue, 10 Feb 2009 12:53:49 EST news153492807 NASA's Swift Gamma-ray Explorer satellite rocketed into space in 2004 on a mission to study some of the highest-energy events in the universe. The spacecraft has detected more than 380 gamma-ray bursts, fleeting flares that likely signal the birth of a black hole in the distant universe. In that time, Swift also has observed 80 exploding stars and studied six comets. http://www.physorg.com/news147542805.html Space & Earth Wed, 03 Dec 2008 16:06:45 EST news147542805 (PhysOrg.com) -- A quiet wind turbine developed in Scotland is now available in the US and Canada. Its developers say that the roof-based turbine can provide significant power for homes and commercial buildings alike. http://www.physorg.com/news144674984.html Technology Fri, 31 Oct 2008 12:29:44 EST news144674984
