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 ...

An unexpected and unexplained gamma-ray signal from beyond the Milky Way found among 13 years of NASA Fermi Telescope data that could be linked to another cosmic mystery.

Gamma-ray bursts, or GRBs, are intense blasts of gamma rays—the highest-energy form of light—that typically last from a fraction of a second to a few minutes in length.

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.

Our solar system was hit by a gamma-ray burst so bright, it blinded space equipment and telescopes. The gamma-ray, dubbed the "brightest of all time," hit our solar system last fall.

Scientists have discovered that the Sun produces higher energy light than was thought possible. An unusual type of telescope detected gamma rays with energies of over 1 tera electron volt, at ...

"This field did not exist before 1989 when the first gamma ray source was detected. At that point, we knew of four sources in the world," said Dave Kieda, professor in the Department of Physics ...
