Washington, April 19 (ANI): New observations of the blazar known as PKS 1424+240 showed that it is the most distant known source of very-high-energy gamma rays, but its emission spectrum now appears highly unusual in light of the new data.

Washington, April 17 (ANI): Two international teams of astronomers studying long-lasting gamma-ray bursts (GRBs) have concluded that they likely arose from the catastrophic death of supergiant stars hundreds of times larger than the Sun.

Washington, February 6(ANI): Scientists have made a major step forward in understanding the structure and behavior of some of the most elusive atomic nuclei in existence, some of which occur only briefly on the surface of exploding stars, thanks to the first set of experiments from the new Advanced Gamma Tracking Array (AGATA).

London, January 22 (ANI): A new study has suggested that a gamma ray burst, the most powerful explosion known in the Universe, may have hit the Earth in the 8th Century.

London, January 20(ANI): The Fermi space telescope may help solve one of physics' greatest mysteries - "dark matter".

Washington, January 8 (ANI): Using a combination of data from NASA's Fermi Gamma-ray Space Telescope and the National Science Foundation's Very Long Baseline Array (VLBA), astronomers have zeroed in on the source of the months-long blast of energy launched by an enormous black hole almost 11 billion years ago swept past Earth in 2011.

Washington, October 30 (ANI): NASA will hold a media teleconference next month to discuss new measurements using gamma rays to investigate ancient starlight with the agency's Fermi Gamma-ray Space Telescope.

Washington, August 24 (ANI): Spacetime may be less like beer and more like sipping whiskey, a physicist has claimed.

Washington, August 14 (ANI): Gamma-ray photons seen emanating from the center of the Milky Way galaxy could support the theory that dark matter exists at the center of galaxies, according to UC Irvine astrophysicists.

London, July 30 (ANI): A possible source of ultra high-energy cosmic rays - gamma-ray bursts, has received a new lease of life in a new study.

Washington, May 30 (ANI): New evidence of ghostly gamma-ray beams suggests that the Milky Way's central black hole was much more active in the past.

London, May 9 (ANI): Since its launch in 2008, the Fermi Gamma-ray space telescope has captured hundreds of gamma-ray bursts (GRBs), flashes of light that, for only a few seconds or minutes, are the brightest objects in the Universe.

Washington, Feb 20 (ANI): The Fermi Gamma-Ray Space Telescope has recorded the ighest energy portion of the gamma-ray bursts, which last for a few seconds.

Washington, Jan 11 (ANI): NASA's Fermi Gamma-ray Space Telescope, which has been surveying high-energy sky for more than three years, is extending its view into a largely unexplored electromagnetic range.

Washington, Jan 8 (ANI): Gamma ray burst, which occurred in a colossal group of stars called a globular cluster may have triggered a mass extinction on Earth 440 million years ago, according to a German researcher.

Washington, Dec 14 (ANI): The remains of shattered Tycho's supernova, which is one of the few supernovae visible to the naked eye in historical records, shine in high-energy gamma rays, subsequently hinting at cosmic ray origins, a new study has revealed.

London, Oct 10 (ANI): A new research has suggested that the massive explosions, termed as gamma-ray bursts, taking place on the other side of the galaxy have the power to devastate life on earth.

Washington, Sept 07 (ANI): An international team of astrophysicists has spotted pulsed gamma ray emissions coming from the Crab Pulsar with energies far higher than expected, surpassing what current theoretical models of pulsars can explain.

London, Sept 19 (ANI): Scottish scientists have created a magnificent gamma ray beam, which is more than a thousand billion times brilliant than the Sun, to revolutionize cancer detection and treatment.

Washington, Sept 17 (ANI): Space scientists are set to launch a balloon up to 130,000 feet with a one-ton instrument payload to measure gamma rays from the Crab Pulsar, the remains of a supernova explosion that lies 6,500 light years from Earth.
