Swift XMM-Newton Satellites Tune Into A Middleweight Black Hole Washington DC (SPX) Nov 11, 2009 
While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. Now, astronomers at NASA's Goddard Space Flight Center in Greenbelt, Md., find that an X-ray source in galaxy NGC 5408 represents one of the best cases for a middleweight black hole to date. "Intermediate-mass black holes ... read morePeckish bird briefly downs big atom smasher 
Geneva (AFP) Nov 9, 2009A peckish bird briefly knocked out part of the world's biggest atom smasher by causing a chain reaction with a piece of bread, the European Organisation for Nuclear Research (CERN) said Monday. Bits of a French loaf dropped on an external electrical power supply caused a short circuit last week, triggering failsafe devices that shut down part of the cooling system of the giant experiment to ... more

Black Holes Produce The Most Energetic Cosmic Radiation
Washington DC (SPX) Nov 05, 2009Blasts of radiation brighter than a trillion suns. Charged particles with the energy of a well-thrown baseball. Jets of magnetized plasma streaming across intergalactic space. What do these have in common? Their energy is derived from black holes. Today, at the 2009 Fermi Symposium in Washington, DC, Charles Dermer, an astrophysicist in the Space Science Division of the Naval Research ... more Nobel Prize Winner Explains Big Bang 
Moscow, Russia (RIA Novosti) Oct 29, 2009The first of a series of lectures to be delivered by the world's topmost scientists, a new Internet project of Dmitry Zimin's Dynasty Foundation and RIA Novosti, has been shown. The lectures are part of the ongoing project, Science without Borders, organized by the Dynasty Foundation and RIA Novosti's Mosaics of Knowledge club. The first lecturer was Nobel Laureate Dr. John Mather. ... more UK Science Benefits From High Performance Computing Investment 
London, UK (SPX) Oct 22, 2009The Science and Technology Facilities Council (STFC) has received Pounds 12.32 million, from the Government's Large Facilities Capital Fund, to invest in new hardware for the UK's High Performance Computing Consortia (HPC) - providing UK particle physicists and astronomers with upgraded HPC technology to address some of the most challenging scientific problems. The new funding will allow ... more Scientists Use Supercomputers To 'See' Black Holes 
Rochester NY (SPX) Oct 21, 2009Scientists at Rochester Institute of Technology have won several grants to further extend their own supercomputer and make use of two of the fastest supercomputers in the world in their quest to "shine light" on black holes. Since light cannot escape from the surface of a black hole, scientists rely upon computer algorithms to study the massive dark objects. Researchers in the Center for ... more |

Invading Black Holes Explain Cosmic Flashes
Leeds, UK (SPX) Sep 22, 2009Black holes are invading stars, providing a radical explanation to bright flashes in the universe that are one of the biggest mysteries in astronomy today. The flashes, known as gamma ray bursts, are beams of high energy radiation - similar to the radiation emitted by explosions of nuclear weapons - produced by jets of plasma from massive dying stars. The orthodox model for this ... more Is Cygnus X-1 Still A Star 
Huntsville AL (SPX) Sep 03, 2009Since its discovery 45 years ago, Cygnus X-1 has been one of the most intensively studied cosmic X-ray sources. About a decade after its discovery, Cygnus X-1 secured a place in the history of astronomy when a combination of X-ray and optical observations led to the conclusion that it was a black hole, the first such identification. The Cygnus X-1 system consists of a black hole with a mas ... more Honey, I Blew Up The Tokamak 
Huntsville AL (SPX) Sep 01, 2009Magnetic reconnection could be the Universe's favorite way to make things explode. It operates anywhere magnetic fields pervade space--which is to say almost everywhere. On the sun magnetic reconnection causes solar flares as powerful as a billion atomic bombs. In Earth's atmosphere, it fuels magnetic storms and auroras. In laboratories, it can cause big problems in fusion reactors. It's ... more Rewriting General Relativity 
Washington DC (SPX) Aug 25, 2009Does an exciting but controversial new model of quantum gravity reproduce Einstein's theory of general relativity? Scientists at Texas A and M University in the US explore this question in a paper appearing in Physical Review Letters and highlighted with a Viewpoint in the August 24th issue of Physics. "If it ain't broke, don't fix it," sums up fairly well how many scientists have viewed ... more |
