Latest Gamma-ray astronomy Stories
Extremely detailed images produced using radio telescopes spread throughout Europe and the US have allowed researchers to pinpoint the exact locations in a stellar explosion where gamma rays are emitted.
When the most massive stars explode as supernovas, they don't fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains?
A long-lasting gamma-ray burst that was first observed last year contained traits similar to those expected from explosions of some of the earliest stars in the universe, claims a new study appearing in The Astrophysical Journal.
All across the Universe high-energy charged particles are found racing in all directions. The source of these particles, collectively called cosmic rays, is masked by the interstellar magnetic field that bends their paths, making them nearly impossible to directly trace.
The HESS-II (High Energy Stereoscopic System) telescope in Namibia has detected gamma rays of only 30 Giga electron volts (GeV) from the Vela pulsar.
A new study using observations from a novel instrument provides the best look to date at magnetic fields at the heart of gamma-ray bursts, the most energetic explosions in the universe. An international team of astronomers from Britain, Slovenia and Italy has glimpsed the infrastructure of a burst's high-speed jet.
A new observatory has begun formal operations in Mexico. The High-Altitude Water Cherenkov Gamma Ray Observatory is designed to study the origin of very high-energy cosmic rays and observe the most energetic objects in the known universe.
Measuring the number and energy of each particle of light or photon since the Big Bang could provide secrets about the nature and evolution of the Universe, such as how similar or different ancient galaxies were compared to the galaxies today.
On Saturday, April 27, the Fermi Gamma-ray Telescope detected a sudden, powerful flux of high-energy gamma-rays, indicating a historic burst event in a distant galaxy. The instrument then notified other telescopes located in space and on the ground that a Gamma-ray Burst (GRB) had been detected.
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...
