For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a ...

Behold! The most powerful explosions in the known universe — gamma-ray bursts. Gamma-ray bursts (GRBs) are the most powerful and violent explosions in the known universe. These brief flashes of ...

Scientists may be a step closer to discovering how gamma-ray bursts come to be some of the most powerful explosions in the known universe. For context, a single gamma-ray burst, or GRB ...

Thunderstorms are known to generate gamma rays, the highest energy radiation on Earth. But pinning the burst to a specific bolt is new.

"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 ...

This is similar to how Kodak detected evidence of U.S. A-bomb testing in 1945 (though they likely didn’t know it at the time). To make sure the balloon captured gamma rays emanating from the ...

An astounding gamma-ray burst, dubbed GRB 221009A, continues to amaze even though it has been more than a year since it was detected. Scientists from Italy have recently published a study that ...

A bright flash of gamma rays from the constellation Boötes that lasted nearly one minute came from a kilonova, as we described in a new paper. This finding challenges what astronomers know about ...

Languages: English. Thunderstorms are far more radioactive than previously thought, routinely producing gamma rays—the highest-energy form of electromagnetic radiation typically associated with ...
