Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

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.

Using a combination of telescopes, astronomers have characterized the closest supernova linked to a fast X-ray transient. The ...

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 ...

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 ...

Sun’s most powerful blast of energy rays just detected ... Nasa 4K Sun timelapse. ... the gamma ray energy is redistributed into particle fragments and light which are observed by the HAWC.

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.

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.

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 ...

An unusual bright blast of light detected by multiple telescopes in December 2021 was the result of a rare cosmic explosion called a kilonova. The explosion created heavy elements such as gold and ...

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.

The ensuing gamma ray burst lasted all but 20 microseconds afterwards. But it was enough to synchronize, for the first time, lightning and dark lightning using ground-based observations.
