Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

Gamma-ray bursts, powerful glares of high-energy that wash through the Universe once every day or so are, for a brief time, the brightest objects in the gamma-ray sky. ESA’s Integral gamma-ray ...

The longest gamma-ray burst ever recorded did not roar for seconds or even minutes, but for a staggering seven hours, forcing astronomers to rethink how some of the most violent explosions in the ...

A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous ...

Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it 'rivals the catalog of deep-sky objects created by Messier 250 years ago', astronomers say.

Down here at the bottom of our ocean of air, it’s easy to get complacent about the hazards our universe presents. We feel safe from the dangers of the vacuum of space, where radiation sizzles and ...

Gamma-ray bursts are not uncommon, but ones like the seven-hour burst detected in 2025 definitely are. Scientists now have an idea about what caused it.

A team of astronomers have observed an explosion in the universe unlike any ever witnessed before. The gamma-ray bursts from outside the Milky Way galaxy repeated several times over the course of a ...

July 25 (UPI) --Scientists have announced a never-before-seen energy peak that resulted from the largest gamma ray burst in history, NASA announced Thursday. The brightest-of-all-time gamma ray burst, ...
