"When we confirmed that the gamma-ray burst was generated by the collapse of a massive star, that gave us the opportunity to test a hypothesis for how some of the heaviest elements in the universe are ...

What happens right before two arcs of lightning smash into each other? An invisible blast of radiation a million times more energetic than a lightning discharge is unleashed in the form of gamma rays, ...

Astronomers believe they have found a rare, massive flare that erupted from an extremely magnetic dead star, or magnetar, that was bright enough to illuminate an entire galaxy. If true, the discovery ...

They were first spotted in the late 1960s by satellites designed to ferret out secret thermonuclear tests by the Chinese and Soviets, but some of the bursts of high-energy gamma rays picked up by ...

Above the cloud tops, thunderstorms throb with a complex, frenetic light show of high-energy radiation. A view from a retrofitted spy plane soaring at 20 kilometers up revealed storms glowing and ...
