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)
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)
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)
NASA's Fermi Telescope Reveals Best-Ever View of Gamma-Ray Sky
A new map combining nearly three months of data from NASA's Fermi Gamma-ray Space Telescope is giving astronomers an unprecedented look at the high-energy cosmos. To Fermi's eyes, the universe is ablaze with gamma rays from sources ranging from within the solar system to galaxies billions of light-years away. view more (2009-03-12)
Next-generation microcapsules deliver 'chemicals on demand'
Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen. view more (2009-10-29)
Climate change -- research suggests it is not a swindle
New research has dealt a blow to the skeptics who argue that climate change is all due to cosmic rays rather than to man-made greenhouse gases. The new evidence shows no reliable connection between the cosmic ray intensity and cloud cover. view more (2008-04-03)
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)
New experiment could reveal make-up of the universe
The detectors will become part of the Advanced Gamma Tracking Array (AGATA) experiment, currently based in Italy, which aims to create a 'fingerprint' of the inside of the atomic nucleus to understand the structure of all matter in the Universe, including human beings and the stars. view more (2009-08-06)

`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 Science and Technology Center (NSSTC) in... view more... (2002-07-10)
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 Stereoscopic System (H.E.S.S.), an array of four... view more...

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)
Keck Study Sheds New Light on 'Dark' Gamma-ray Bursts
Gamma-ray bursts are the universe's biggest explosions, capable of producing so much light that ground-based telescopes easily detect it billions of light-years away. view more (2009-06-09)
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)
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)
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)
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)
