Shrouded in mystery for decades, gamma-ray bursts are the brightest explosions since the Big Bang and emerge from only the most violent cosmic events.

Gamma-ray bursts are the brightest explosions the cosmos has to offer, besides the Big Bang—the explosion that happened 13.77 billion years ago that marks the beginning of time. The BOAT was ...

We are also creating a table of the past gamma-ray bursts and the observations of the ozone layer and trying to see if they match,” he said. Nature Communications, 2023. DOI: 10.1038/s41467-023 ...

On Oct. 9, 2022, Swift’s X-Ray Telescope captured the afterglow of the brightest gamma-ray burst every recorded, called GRB 221009A. Credit: NASA/Swift/A. Beardmore (University of Leicester) ...

Gamma rays are the most energetic form of electromagnetic radiation. In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.

Over 90% of the gamma-ray flashes come from galaxies called blazars, which are powered by feeding supermassive black holes. A new NASA animation shows what the sky over Earth would look like to ...

A huge surge of gamma-ray energy from space caused electric currents to flow through the surface of the Earth on October 9, scientists have said.. This gamma-ray burst, named GRB221009A, is the ...

The first gamma-ray bursts were discovered by accident in the 1960's, by spy satellites looking for gamma-rays from secret nuclear bomb tests.

These massive releases of energy are rivaled by few in terms of sheer ferocity. In just a few seconds, a gamma-ray burst releases more energy than our sun is capable of generating in the entirety of ...

HUNTSVILLE, Ala. — Three researchers associated with the University of Alabama in Huntsville (UAH) discovered the brightest gamma-ray burst ever detected, approximately 2.4 billion light-years away.

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