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)
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)
Integral - tracking extreme radiation across the Universe
The world`s most advanced gamma-ray space telescope Integral [International Gamma Ray Astrophysics Laboratory] was successfully launched today [17 October 2002] from the Baikonur Cosmodrome, Kazakhstan. Integral will provide first-hand observations of cosmic objects that release some of the most energetic radiation of the Universe. British... view more... (2002-10-11)
GAMMA RAYS AND DARK MATTER
For a long time it has been known that the Milky Way is surrounded by a (nearly spherical) halo of invisible matter, which contributes at least 90% of the whole galactic mass. Yet, almost nothing is known about the nature of such a dark halo. view more (1999-02-26)
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)
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)
Astronomers find record-old cosmic explosion
Using the powerful one-two combo of NASA's Swift satellite and the Gemini Observatory, astronomers from a number of institutions, including Johns Hopkins, have detected a mysterious type of cosmic explosion farther back in time than ever before. view more (2008-01-10)
Mysterious energy burst stuns astronomers
In a shock finding, astronomers using CSIRO's Parkes telescope have detected a huge burst of radio energy from the distant universe that could open up a new field in astrophysics. view more (2007-09-28)
Scientists piece together the most distant cosmic explosion
In this week's issue of Nature, scientists at Penn State University and their U.S. and European colleagues discuss how this explosion, detected on 4 September 2005, was the result of a massive star collapsing into a black hole. view more (2006-03-09)
Everyone wants gamma-ray eyes!
Even before ESA`s Integral gamma-ray observatory was launched, astronomers were competing to win time to use this state-of-the-art observatory. The Integral Science Operations Centre in Noordwijk, The Netherlands, received hundreds of excellent proposals. ESA expects Integral to revolutionise the way we think about the violent Universe.... view more... (2002-10-29)
Integral expands our view of the gamma-ray sky
Integral's latest survey of the gamma-ray universe continues to change the way astronomers think of the high-energy cosmos. With over seventy percent of the sky now observed by Integral, astronomers have been able to construct the largest catalogue yet of individual gamma-ray-emitting celestial objects. view more (2007-02-21)
Physicists find evidence for highest energy photons ever detected from Milky Way's equator
Physicists at nearly a dozen research institutions, including New York University, have discovered evidence for very high energy gamma rays emitting from the Milky Way, marking the highest energies ever detected from the galactic equator. view more (2005-12-14)
Searching the heavens
A new space mission, due to launch this month, is going to shed light on some of the most extreme astrophysical processes in nature - including pulsars, remnants of supernovae, and supermassive black holes. view more (2008-05-01)
ESA steps towards a great black hole census
Astronomers using ESA's orbiting gamma-ray observatory, Integral, have taken an important step towards estimating how many black holes there are in the Universe. view more (2006-09-08)
Fermi Large Area Telescope reveals pulsing gamma-ray sources
Scientists at the Naval Research Laboratory (NRL) Space Science Division and a team of international researchers have positively identified cosmic sources of gamma-ray emissions through the discovery of 16 pulsating neutron stars. view more (2009-09-10)
NASA's Fermi Telescope Probes Dozens of Pulsars
With NASA's Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars. view more (2009-07-07)
Fog lifted on 'dark' gamma-ray bursts, mysterious counterparts to bursts with an afterglow
Gamma-ray bursts, with their ability to pierce through gas and dust to shine brightly across the universe, are revealing areas of intense star formation and stellar death where astronomers have been unable to look - the dusty corners of otherwise dust-free galaxies. view more (2009-06-09)
Integral looks at Earth to seek source of cosmic radiation
Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA's Integral gamma-ray observatory have tried an unusual method: observing Earth from space. view more (2006-03-17)

Possible Origin of Cosmic Rays Revealed with Gamma Rays
An international team of astronomers (including the UK) has produced the first ever image of an astronomical object using high energy gamma rays, helping to solve a 100 year old mystery - an origin of cosmic rays. Their research, published in the Journal Nature on November 4th, was carried out using the High Energy Stereoscopic System (H.E.S.S.),... view more... (2004-11-02)
