What are some recent exciting gamma-ray-burst developments? There have been a couple of really odd GRBs detected in the last few years. GRB 211211A was a long GRB detected in December of 2022.

Nicknamed “BOAT”—that is, “brightest of all time”—the gamma-ray burst known as GRB 221009A washed over Earth on October 9, 2022. Emerging from an extragalactic source, this burst was ...

Indeed, it is widely believes that a gamma-ray burst caused the Ordovician extinction roughly 443 million years ago. Fortunately for contemporary humans, no GRBs in recent memory have been close ...

While the relative proximity of a burst as powerful as GRB221009A is a boon to science, astronomers are not keen to see a gamma-ray burst much closer to Earth. Especially not in our galaxy.

Last year, scientists detected the brightest gamma-ray burst ever seen, and it continues to leave them scratching their heads — here's why.

Scientists have found a mysterious signal in the brightest gamma ray burst ever detected, and now they know what caused it. When you purchase through links on our site, we may earn an affiliate ...

All eyes are on the source of the record-breaking gamma-ray burst that lit up the sky last week. On Oct. 9, a beam of light more energetic than astronomers had ever seen zipped past our planet, ...

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.
