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.

Gamma-ray bursts are useful measurement tools in cosmology — with a few caveats. The main one is that it takes the observation of a tremendously large number of GRBs to draw meaningful ...

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.

Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022. It has since been dubbed the "B.O.A.T.", the brightest of all time.

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 ...

Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2023 / 03 / 230328145539.htm ...

A gamma-ray burst, which lit up our galaxy last October, was the "brightest burst" ever seen and a once-in-10,000-year explosion, according to NASA.

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. Once scientific satellites began looking for them, ...

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 ...
