Discovery offers new understanding of diabetes drug target
Scientists at the University of Leicester have published findings about a new advance in the study of major diabetes drug target. view more (2008-09-26)
UO plays key role in LIGO's new view of a cosmic event
An international team of physicists, including University of Oregon scientists, has concluded that last February's intense burst of gamma rays possibly coming from the Andromeda Galaxy lacked a gravitational wave. That absence, they say, rules out an initial interpretation that the burst came from merging neutron stars or black holes within... view more... (2008-01-04)
European Satellites Probe a New Magnetar
On Aug. 22, 2008, NASA's Swift satellite reported multiple blasts of radiation from a rare object known as a soft gamma repeater, or SGR. view more (2009-06-17)
A Strange Supernova with a Gamma-Ray Burst
On April 25, the BeppoSAX satellite detected a Gamma-Ray Burst from the direction of the constellation Telescopium, deep in the southern sky. Although there is now general consensus that they originate in very distant galaxies, the underlying physical causes of these events that release great amounts of energy within seconds are still puzzling... view more...

Integral identifies supernova rate for Milky Way
Using ESA's Integral observatory, an international team of researchers has been able to confirm the production of radioactive aluminium (Al 26) in massive stars and supernovae throughout our galaxy and determine the rate of supernovae-one of its key parameters. view more (2006-01-09)
On October 10th at the Canaries the Magic telescope will be inaugurated: the biggest in the world for the study of gamma radiation
On October 10th the Magic Telescope (Major Atmospheric Gamma Imaging Cherenkov telescope) will be inaugurated. The telescope is located La Palma island, 2200 meters above the sea level at the Observatory Roque de los Muchachos, of the Itituto Astrofisico de Canarias. With his 17-meter-diameter-mirror and 240 square meters surface, it's the largest... view more... (2003-10-06)
Brightest stellar explosion heralds new type of long-distance astronomy
A flash of light that blinded even small telescopes six months ago was the brightest astronomical explosion ever observed - visible to the naked eye despite originating halfway across the universe. view more (2008-09-11)
A new unidentified very high energy gamma-ray source in our Galaxy
A European team based in Heidelberg (Germany) and their colleagues from the HEGRA collaboration have discovered a new, unidentified, very high energy gamma-ray source in our Galaxy. This source was detected via ground-based observations of the Imaging Atmosphere Cherenkov Telescope System. view more (2004-12-14)
NSF / NASA 'Firefly' CubeSat Mission to Study Link Between Lightning and Terrestrial Gamma Ray Flashes
Massive energy releases occur every day in the upper reaches of Earth's atmosphere. Lightning may give rise to these bursts of radiation. However, unlike the well-known flashes of light and peals of thunder familiar to Earth-dwellers, these energy releases are channeled upward and can be detected only from space. view more (2008-11-18)
Blast from the past gives clues about early universe
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). view more (2009-10-29)
Scientists predict how to detect a fourth dimension of space
Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's General Theory of Relativity. view more (2006-05-26)
NASA'S Fermi Telescope Discovers First Gamma-Ray-Only Pulsar
About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. Discovered by NASA's Fermi Gamma-ray Space Telescope, the object, called a pulsar, is the first one known that only "blinks" in gamma rays. view more (2008-10-17)
Iowa State researchers contribute to discovery of gamma rays from starburst galaxy
Iowa State University astrophysicists contributed to the recent discovery that a galaxy quickly creating new stars is also a source of high energy gamma rays. view more (2009-11-03)
NASA's Fermi Mission, Namibia's HESS Telescopes Explore a Blazar
An international team of astrophysicists using telescopes on the ground and in space have uncovered surprising changes in radiation emitted by an active galaxy. view more (2009-03-19)
Iowa State astrophysicists provide the eyes for new gamma ray telescope system
There's a "First Light Fiesta" in the works at Mt. Hopkins near Amado, Ariz. And Iowa State University astrophysicists will be among those enjoying the celebration of a new telescope system and all the science it will produce. view more (2007-04-20)
Astronomers use gamma-ray burst to probe star formation in the early universe
The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. view more (2009-01-07)
VERITAS telescopes help solve 100-year-old mystery: The origin of cosmic rays
Nearly 100 years ago, scientists detected the first signs of cosmic rays - subatomic particles (mostly protons) that zip through space at nearly the speed of light. view more (2009-11-03)
Astronomers shed surprising light on our galaxy's black hole
In the most comprehensive study of Sagittarius A (Sgr A), the enigmatic supermassive black hole in the center of the Milky Way Galaxy, astronomers - using nine ground and space-based telescopes including the Hubble Space Telescope and the XMM-Newton X-ray Observatory - have discovered that Sgr A* produces rapid flares close to the... view more...

NRL's Large Area Telescope explores high-energy particles
NASA's Fermi Gamma-ray Space Telescope is making some exciting discoveries about cosmic rays and the Large Area Telescope aboard Fermi is the tool in this investigation. view more (2009-07-29)
Biggest ever Gamma Ray search starts in Namibia
The world's most sensitive Gamma Ray telescopes are being inaugurated in Namibia (in Southwest Africa) on September 3rd. The High Energy Stereoscopic System (H.E.S.S.), a European/African collaboration in which the UK is a partner, will look for Gamma Rays produced by the most energetic particles in the Universe. The array initially consists of... view more... (2002-08-28)
