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

The strong currents of air in thunderstorms can cause air and water to shoot up and down very quickly. When this happens, ...

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 ...
