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)
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)
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 programme. It is the world`s most advanced... view more... (2002-10-02)
Astronomers hot on the trail of nature's exotic flashers
Astronomers have uncovered tantalizing insights into the origin of short gamma-ray bursts - mysterious, split-second high-energy flashes that have eluded detailed study until now. view more (2005-05-31)
NASA's Swift Catches Farthest Ever Gamma-Ray Burst
NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away. view more (2008-09-23)
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)
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)
NASA's Fermi Telescope Detects Gamma-Ray From
Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA's Fermi Gamma-ray Space Telescope. view more (2009-11-03)
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)
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 extraordinary explosions from the X-rays given out... view more... (2003-09-17)
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)
NASA's Fermi Explores High-energy
Since its launch last June, NASA's Fermi Gamma-ray Space Telescope has discovered a new class of pulsars, probed gamma-ray bursts and watched flaring jets in galaxies billions of light-years away. view more (2009-05-05)
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)
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 mission, which produced a complete map of the sky in... view more... (2002-10-17)
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 confirms explosive prediction made by astrophysicists in 1999
NASA's Swift satellite and ground-based telescopes have discovered the most distant exploding star on record, confirming a 1999 prediction made by University of Chicago astrophysicist Don Lamb and Daniel Reichart, who was then a graduate student at Chicago. view more (2005-09-13)
