Latest Gamma-ray astronomy Stories
Scientists at the Naval Research Laboratory (NRL) Space Science Division and a team of international researchers have positively identified cosmic sources of gamma-ray emissions through the discovery of 16 pulsating neutron stars.
The largest-ever gamma-ray telescope is set to collect its â€œfirst lightâ€ at an opening ceremony on Saturday.
An international team of astronomers has used a U.S.
An international team of astrophysicists using telescopes on the ground and in space have uncovered surprising changes in radiation emitted by an active galaxy.
WASHINGTON, Feb. 19 /PRNewswire-USNewswire/ -- The first gamma-ray burst to be seen in high-resolution from NASA's Fermi Gamma-ray Space Telescope is one for the record books. The blast had the greatest total energy, the fastest motions and the highest-energy initial emissions ever seen.
GREENBELT, Md., Feb. 2 /PRNewswire-USNewswire/ -- Astrophysicist Dr.
Thanks to ESA and UK technology transfer support, a British company has developed a device based on the gamma-ray detection equipment used in ESAâ€™s Integral astronomy satellite to detect and identify the radioactive material mixed with conventional explosives in â€˜dirty bombsâ€™.
The U.S. space agency says its newest space telescope, the Gamma-ray Large Area Space Telescope, or GLAST, is in the process of being activated. The Delta II rocket carrying GLAST lifted off June 11 from launch pad 17-B at the Cape Canaveral Air Force Station in Florida.
At 12:05 p.m. EDT, the Delta II rocket easily lifted the GLAST spacecraft off the launch pad, out of smoke and clouds and into a beautiful Florida sky headed for space.
Gamma-ray bursts are short-lived events, lasting between a few milliseconds to a few minutes. The brightest of them emit more energy in a few seconds than our Sun will emit in its whole 10 billion year lifetime.
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...
