Latest Gamma-ray astronomy Stories
NASAâ€™s Gamma-ray Large Area Space Telescope (GLAST) has arrived at the Naval Research Laboratory (NRL) in Washington for its final round of testing.
With eyes that peer into the most energetic phenomena in the universe, ESAâ€™s Integral has been setting records, discovering the unexpected and helping understanding the unknown over its first five years.
NASA's next major space observatory, the Gamma-ray Large Area Space Telescope (GLAST), is one step closer to unveiling the mysteries of the high-energy universe.
Mechanism explains how the most energetic form of light can be produced in areas dominated by bright, young stars
Integral's latest survey of the gamma-ray universe continues to change the way astronomers think of the high-energy cosmos. Astronomers have been able to construct the largest catalogue yet of individual gamma-ray-emitting celestial objects.
A new theory to explain the high-energy gamma-ray emissions from collapsing stars has been put forward by an international team of researchers.
ESA's gamma-ray observatory, Integral, has spotted a rare kind of gamma-ray outburst. The vast explosion of energy allowed astronomers to pinpoint a possible black hole in our Galaxy.
Scientists using NASA's Swift satellite have observed two dozen recent star explosions, called supernovae, quickly after the event and have discovered never-before-seen properties, some of which run counter to prevailing theories.
A cosmic explosion seen last February may have been the "tip of an iceberg," showing that powerful, distant gamma ray bursts are outnumbered ten-to-one by less-energetic cousins, according to an international team of astronomers.
Thanks to a clever piece of design and a sophisticated piece of analysis by European astronomers, Integral - ESAâ€™s orbiting gamma ray observatory - can now make images of the most powerful gamma-ray bursts even if the spacecraft itself is pointing somewhere completely different.
Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...
