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)

Astronomers link old stars and mysterious cosmic explosions
Cosmic gamma-ray bursts, the most powerful explosions in the universe, have the extreme brilliance of a billion billion Suns and occur several times a day.   view more (2005-12-15)

ESA`s X-ray space telescope proves supernova can cause mysterious gamma-ray bursts
Gamma-ray bursts are the most powerful explosions ever detected in the Universe. They are also one of the greatest mysteries of modern astronomy, since so far no clear evidence has existed to prove what causes them. Until now, there have been two `prime suspects` for what makes gamma-ray bursts,... view more (2002-04-04)

The quiet explosion
A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts.   view more (2008-07-25)

Two cosmic bursts upset tidy association between long gamma-ray bursts and supernovae
Two brilliant flashes of light from nearby galaxies are puzzling astronomers and could indicate that gamma-ray bursts, which signal the birth of a black hole, are more diverse than once thought.   view more (2006-12-21)

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... view more (2002-08-28)

Scientists detect first afterglow of short gamma-ray bursts
In the powerful, fast-fading realm of gamma-ray bursts, scientists say they have detected for the first time a lingering afterglow of the shortest types of bursts, which themselves disappear within a second.   view more (2002-02-18)

High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy... view more (2004-09-22)

Astronomers discover new kind of black-hole explosion
Scientists have discovered what appears to be a new kind of cosmic explosion - a "hybrid gamma-ray burst" - which will be the subject of four articles to be published in the journal Nature on 21 December 2006.   view more (2006-12-21)

Europe opens a window onto a violent Universe
ESA PR 66-2002. The European Space Agency has today launched a new observatory set to revolutionise the branch of astrophysics that seeks to unravel the secrets of the highest-energy - and therefore the most violent - phenomena in the Universe. This comes 20 years after the end of ESA`s COS-B... view more (2002-10-17)

NASA's GLAST Satellite Gets Twin Solar Panels in Prep for Launch
Preparations for launching NASA's Gamma-ray Large Area Telescope (GLAST) satellite are underway at NASA's Kennedy Space Center (KSC), Fla. NASA KSC's "NASA Expendable Launch Vehicle Status Report" on Thursday, March 20, noted that GLAST's twin solar panels have been attached.   view more (2008-04-02)

A simple survey yields a cosmic conundrum
A survey of galaxies observed along the sightlines to quasars and gamma-ray bursts-both extremely luminous, distant objects-has revealed a puzzling inconsistency. Galaxies appear to be four times more common in the direction of gamma-ray bursts than in the direction of quasars.   view more (2006-08-01)

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... view more (2003-10-06)

GLAST Observatory renamed for Fermi, reveals entire gamma-ray sky
The U.S. Department of Energy (DOE) and NASA announced today that the Gamma-Ray Large Area Space Telescope (GLAST) has revealed its first all-sky map in gamma rays.   view more (2008-08-27)

Delta II Rocket Coming Together for NASA's GLAST Satellite Launch
The Delta II 7920-H, or "Heavy," rocket that will launch NASA's Gamma-ray Large Area Telescope (GLAST) satellite is in the process of being assembled on Launch Pad 17-B at Cape Canaveral Air Force Station, Fla.   view more (2008-04-15)

Molecules of positronium observed in the laboratory for the first time
Physicists at UC Riverside have created molecular positronium, an entirely new object in the laboratory. Briefly stable, each molecule is made up of a pair of electrons and a pair of their antiparticles, called positrons.   view more (2007-09-13)

Gamma-ray bursts: are we safe?
For a few seconds every day, Earth is bombarded by gamma rays created by cataclysmic explosions in distant galaxies. Such explosions, similar to supernovae, are known as 'gamma-ray bursts' or GRBs. Astronomers using ESA's X-ray observatory, XMM-Newton, are trying to understand the cause of these... view more (2003-09-17)

Where are the supermassive black holes hiding?
European and American scientists, on a quest to find super-massive black holes hiding in nearby galaxies, have found surprisingly few. Either the black holes are better hidden than scientists realised or they are lurking only in the more distant universe.   view more (2006-07-27)

Integral - tracking extreme radiation across the Universe
INFO 8-2002. Integral is the International Gamma Ray Astrophysics Laboratory of the European Space Agency. It is a cooperative mission with Russia and is scheduled for launch on 17 October 2002 from the Baikonur Cosmodrome, Kazakhstan, on a Russian Proton rocket, the Russian contribution to the... view more (2002-10-02)

UC Santa Cruz physicists eagerly await launch of NASA space telescope they helped build

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... view more (2008-01-04)

Gamma knife effective in treating trigeminal neuralgia
Research at the Comprehensive Cancer Center at Wake Forest University Baptist Medical has shown that Gamma Knife Stereotactic Radiosurgery (GKRS) is an effective treatment for trigeminal neuralgia, a common condition characterized by excruciating facial pain.   view more (2005-10-20)

`Quiet` star wasn`t quiet after all, say astronomers
For more than two years the star was `quiet`. Or so astronomers thought. But the X-ray pulsar EXO 2030+375 was abuzz with activity. Scientists simply lacked the ability to `hear` it over the hum of a nearby black hole. Now a study by scientists at the University of Southampton, the National Space... view more (2002-07-10)
