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.

A gamma-ray burst, the most powerful kind of explosion known in the universe, may have triggered a mass extinction on Earth within the past billion years, researchers say.

Multiple space and ground-based telescopes witnessed one of the brightest explosions in space when it reached Earth on October 9. The gamma ray burst may be one of the most powerful ever recorded ...

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 ...

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 ...

In addition, the flux at lower gamma-ray energies (200 to 400 keV) agreed with the theoretical predictions as well. “The line fluxes indicate that an enormous quantity of radioactive nickel was ...

NASA has confirmed that our solar system was struck by a gamma-ray burst originating 1.9 billion light-years away that was brighter than any since the beginning of human civilization in a "1 in ...
