A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it changed Earth’s atmosphere, according to scientists. Gamma rays are ...

This lack of detection led scientists to hypothesize that by the time gamma-ray bursts from distant exploding stars reached Earth, they were no longer powerful enough to visibly shake up the ...

that here on Earth we typically detect strong gamma-ray bursts only from the detonation of nuclear bombs. The earth's atmosphere blocks most gamma rays from space, so gamma-ray astronomy was not ...

Previous flares observed from the distant galaxy consisted of a few gamma rays per minute hitting the team's detector over several days ... to detect very-high-energy gamma-ray bursts from a galaxy ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

The gamma-ray burst (GRB) occurred two billion light-years from Earth and illuminated much of the galaxy. Images of the rare and powerful cosmic phenomenon show a halo and "bullseye" like shapes.
