A new study of a star undergoing the throes of a supernova death has revealed that bursts of X-radiation known as fast-X-ray ...

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.

The burst was so bright that it bounced off the Moon and illuminated Earth’s upper atmosphere, surpassing the brightness of a ...

Scientists traced a high-energy blast of radiation - called a gamma-ray burst - to the merger of two neutron stars and an explosion called a kilanova that resulted from the cosmic collision.

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 ...

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.

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 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 ...
