The international CTAO LST Collaboration has released remarkable findings from observations of GRB 221009A—the brightest ...

A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into reality.

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

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 ...

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.

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.

According to Dr. Ubertini, if the gamma ray burst was a million times larger, it could have ionized enough ozone to weaken the protective barrier for days or months. But the chances of that ...

A gamma-ray pulsar milestone inspires innovative astrophysics and applications Date: November 28, 2023 Source: Naval Research Laboratory Summary: Scientists have announced the discovery of nearly ...

Gamma-ray bursts were initially spotted in the late 1960s, and since then, they have presented scientists with an enduring puzzle as the exact mechanism that creates these bursts of high-energy ...

The researchers believe that the centers of such old galaxies are cloaked in vast amounts of gas and dust, which could obscure the gamma-ray burst. That would mean the 2019 event was an exception.
