This Powerful Gamma-Ray Blast Was the ‘Brightest of All Time’ Astronomers are “in awe” of the high-energy explosion, probably caused by a giant star’s death ...

Dubbed the "brightest of all time," or the BOAT, a gamma-ray burst detected in 2022 continues to astound astronomers, revealing severe effects in Earth's atmosphere.

A once-in-a-civilization burst of gamma rays set off an observing spree by more than 160 telescopes. It’s forcing scientists to revisit long-held theories—and it’s not done yet.

For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a terrestrial gamma-ray flash (TGF). Researchers at the University of ...

An invisible blast of radiation a million times more energetic than a lightning discharge is unleashed in the form of gamma rays, before disappearing almost as quickly as it came.

A groundbreaking new survey from China’s LHAASO observatory has unveiled powerful ultrahigh-energy gamma-ray emissions across ...

The explosive outburst was detected by NASA’s Fermi Gamma-ray space telescope, the Neil Gehrels Swift Observatory, and the Wind spacecraft. The cosmic blast was first detected on Sunday, October ...

Late last year, scientists spotted a 50-second-long blast of energy coming towards Earth, known as a gamma-ray burst or GRB, which are the most powerful explosions in the universe.

A long gamma ray burst, one of the most powerful phenomena known, was traced back to a rare kilonova, leaving astrophysicists baffled. Epic Cosmic Blast Is Unlike Anything Astronomers Have Seen ...

When astronomers pointed other telescopes at the part of the sky where this large blast of gamma rays – named GRB211211A – came from, they saw a glow of visible and infrared light known as a ...
