Theoretically, if one of these gamma-ray bursts happened within 1,000 light-years of Earth, it could wipe out all life on our planet. When you purchase through links on our site, we may earn an ...

This gamma-ray burst, named GRB221009A, is the strongest in recorded history, ... The GRB [gamma-ray burst] afterglow is booming bright at all wavelengths, including optical and infrared.

A new method to exploit Gamma-Ray Bursts (GRBs), the most energetic explosions in the universe, as independent measurements of the Universe’s expansion rate has been discovered in optical ...

On Dec. 11, 2021, several observatories and satellites recorded a very bright, 50-second gamma-ray burst and optical, infrared and x-ray emissions associated with the burst.

And it was remarkably nearby for a gamma-ray burst: about 1 billion light-years from Earth, ... It was a completely different kind of optical signal, one that we associate with a kilonova, ...

Artist impression of gamma ray burst. (Image credit: NASA) The odds. To catch a gamma-ray burst in the oldest known galaxy during a random imaging campaign seemed a bit too lucky.

When astronomers spotted a powerful gamma-ray burst (GRB) in October 2019, the most likely explanation was that it was produced by a massive dying star in a distant galaxy exploding in a supernova.

On Dec. 11, 2021, several observatories and satellites recorded a very bright, 50-second gamma-ray burst and optical, infrared and x-ray emissions associated with the burst.

Long-duration gamma-ray bursts like B.O.A.T. emerge when a core of a ... In radio and X-ray wavelengths — as well as in optical light — astronomers can observe an afterglow effect caused by ...

Back in 2017, they discovered that short gamma-ray bursts—those lasting just a couple of seconds—generated the hot, dense, and neutron-rich conditions necessary to forge heftier members of the ...
