Latest Gamma-ray astronomy Stories
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.
A new dark matter experiment is underway in which dark matter particles could potential be directly measured. The experiment, known as COUPP-60, sits a mile and a half underground in Ontario, Canada.
A team of physicists has made new observations of the blazar known as PKS 1424+240 that reveal it is the most distant known source of very high-energy gamma rays.
As we search the heavens, one of the striking observations is that we are constantly bombarded by a stream of extremely high energy charged particles, traveling at nearly the speed of light.
NASA’s Fermi Gamma-ray Space Telescope, the most advanced space-based gamma-ray mission ever launched is turnings its eye to the problem of dark matter.
Astronomers have made the most accurate measurement of starlight in the universe and have used this to establish the total amount of light from all of the stars that have ever shone.
This week, ESA’s Integral space observatory celebrates ten years since launch on 17 October 2002.
NASA said that its Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun on March 7.
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...
