(PhysOrg.com) -- As elements of the integrated circuits running our computers, phones and electronics, silicon wafers are everywhere. An ESA-led effort is establishing an out-of-this-world use for these commonplace items: when stacked together precisely by the thousand they promise to deliver astronomy?s clearest X-ray view yet of the most violent regions of space. http://www.physorg.com/news180626931.html Space & Earth Mon, 21 Dec 2009 14:09:29 EST news180626931 Black holes are some of the most exotic objects in the universe. They are the final evolutionary stage of giant stars much larger than the sun. When these stars explode, their cores collapse down to the size of large asteroid. That produces gravitational fields so intense that not even light can escape, reaching a point where space and time as we know them cease to exist. http://www.physorg.com/news180297652.html Space & Earth Thu, 17 Dec 2009 19:00:02 EST news180297652 (PhysOrg.com) -- It's an unlikely place to build a NASA telescope: a leafy estate in Irvington, N.Y., that once belonged to the son of Alexander Hamilton. Inside a hangar-like building on the site, which is home to Columbia`s Nevis Laboratories for experimental physics, Charles Hailey is assembling mirrors for NuSTAR, the most sensitive X-ray telescope ever constructed. http://www.physorg.com/news180286322.html Space & Earth Thu, 17 Dec 2009 15:34:11 EST news180286322 (PhysOrg.com) -- Within a decade scientists could be able to detect the merger of tens of pairs of black holes every year, according to a team of astronomers at the University of Bonn`s Argelander-Institut fuer Astronomie, who publish their findings in a paper in Monthly Notices of the Royal Astronomical Society. By modelling the behaviour of stars in clusters, the Bonn team find that they are ideal environments for black holes to coalesce. These merger events produce ripples in time and space (gravitational waves) that could be detected by instruments from as early as 2015. http://www.physorg.com/news180173220.html Space & Earth Wed, 16 Dec 2009 08:08:01 EST news180173220 (AP) -- Twenty-six operations put healthy kidneys into 13 desperately ill people: Doctors in the nation's capital just performed a record-setting kidney swap, part of a pioneering effort to expand transplants to patients who too often never qualify. http://www.physorg.com/news179993652.html Medicine & Health Mon, 14 Dec 2009 06:15:28 EST news179993652 An international team of scientists has observed four super-massive black holes at the center of galaxies, which may provide new information on how these central black hole systems operate. Their findings are published in December's first issue of the journal Astronomy and Astrophysics. http://www.physorg.com/news179690529.html Space & Earth Thu, 10 Dec 2009 18:40:01 EST news179690529 (PhysOrg.com) -- This composite image of data from three different telescopes shows an ongoing collision between two galaxies, NGC 6872 and IC 4970. http://www.physorg.com/news179682939.html Space & Earth Thu, 10 Dec 2009 15:56:28 EST news179682939 (PhysOrg.com) -- Studies of one of the galaxy's most active black-hole binaries reveal a dramatic change that will help scientists better understand how these systems expel fast-moving particle jets. http://www.physorg.com/news179665092.html Space & Earth Thu, 10 Dec 2009 10:59:29 EST news179665092 (PhysOrg.com) -- The countdown clock is ticking, with just days to go before the Wide-field Infrared Survey Explorer, or WISE, rockets into space on a mission to map the entire sky in infrared light. http://www.physorg.com/news179601759.html Space & Earth Wed, 09 Dec 2009 17:23:19 EST news179601759 (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) -- 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 Understanding the evolution of galaxies is one of the biggest questions confronting astronomers today. Looking at distant astronomical objects gives scientists important clues to the origins of the Milky Way Galaxy and other galaxies in the local universe. http://www.physorg.com/news179512073.html Space & Earth Tue, 08 Dec 2009 16:28:26 EST news179512073 (PhysOrg.com) -- Due to their violent nature and long distance from Earth, black holes and their surroundings are very difficult to study. Currently, the main method to observe a black hole is to use an X-ray satellite to detect the X-ray fluorescence emitted by a black hole`s companion star as the star`s material falls into the black hole. But now, scientists have developed a laser-driven method to generate a flash of brilliant Planckian X-rays in the lab that can be used to simulate the X-rays that exist near black holes. The new results contrast with the generally accepted explanation for the origins of these astronomical features, and may also help scientists test the complex computer codes used in X-ray astronomy. http://www.physorg.com/news179398351.html Physics Mon, 07 Dec 2009 11:30:02 EST news179398351 (PhysOrg.com) -- Donhee Ham, Gordon McKay Professor of Electrical Engineering and Applied Physics, uses his personal energy and understanding of physics to design innovative integrated circuits. http://www.physorg.com/news179085037.html Physics Thu, 03 Dec 2009 20:50:02 EST news179085037 (PhysOrg.com) -- Which come first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside? A brand new scenario has emerged from a recent set of outstanding observations of a black hole without a home: black holes may be `building` their own host galaxy. This could be the long-sought missing link to understanding why the masses of black holes are larger in galaxies that contain more stars. http://www.physorg.com/news178804126.html Space & Earth Mon, 30 Nov 2009 11:49:22 EST news178804126
