Swift Satellite records early phase of gamma ray burst
UK astronomers, using a telescope aboard the NASA Swift Satellite, have captured information from the early stages of a gamma ray burst - the most violent and luminous explosions occurring in the Universe since the Big Bang. view more (2009-03-03)
Astronomers find first ever gamma ray clock
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays - the most energetic such signal ever observed. view more (2006-11-28)
Robotic telescope unravels mystery of cosmic blasts
Scientists have used the world's largest robotic telescope to make the earliest-ever measurement of the optical polarisation* of a Gamma Ray Burst (GRB) just 203 seconds after the start of the cosmic explosion. This finding, which provides new insight into GRB physics, is published in Science today (15th March 2007). view more (2007-03-19)
MAGIC discovers variable very high energy gamma-ray emission from a microquasar
In a recent issue of Science Magazine, the Major Atmospheric Gamma-ray ImagingCherenkov (MAGIC) Telescope has reported the discovery of variable very high energy (VHE) gamma-ray emission from a microquasar. view more (2006-05-19)
First gamma-ray-only pulsar observation opens new window on stellar evolution
About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. view more (2008-10-17)
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)
Space Technology And Dental Techniques Combine In New Cancer Detector
A new generation of gamma cameras is on the horizon, thanks to a collaboration between the BioImaging Unit of the Space Research Centre at the University of Leicester, the Institute for Cancer Research at the Royal Marsden Hospital (Surrey) and medical physicists at the Leicester Royal Infirmary. Dr John Lees, who leads the BioImaging Unit, is... view more... (2004-06-24)
Gamma-ray photon race ends in dead heat; Einstein wins this round
Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA's orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. view more (2009-10-29)
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)
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)
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)
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)
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)
NASA's Swift, Fermi Probe Fireworks From a Flaring Gamma-Ray Star
Astronomers using NASA's Swift satellite and Fermi Gamma-ray Space Telescope are seeing frequent blasts from a stellar remnant 30,000 light-years away. view more (2009-02-11)
Fermi telescope caps its first year with a glimpse of space-time
During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. view more (2009-10-29)
The Double Firing Burst
Astronomers from around the world combined data from ground- and space-based telescopes to paint a detailed portrait of the brightest explosion ever seen. The observations reveal that the jets of the gamma-ray burst called GRB 080319B were aimed almost directly at the Earth. view more (2008-09-11)
