It's a celestial event that has astronomers both excited and puzzled. Dan Smith has the story of how a gamma-ray burst across ...

Astronomers may have recorded the violent birth of one of the weirdest objects our Universe is capable of producing. In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team ...

GRB 250702B was initially detected by NASA's Fermi Gamma-ray Space Telescope on July 2, 2025, but its location was uncertain. The following day, GRB 250702B was investigated by the Very Large ...

A giant explosion that lit up the sky didn't just rock the cosmos – it absolutely rattled our understanding of the Universe's most powerful outbursts. The gamma-ray burst (GRB) recorded on 2 July 2025 ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

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 Osaka ...

The burst seems to have been caused by a highly extraordinary event, but scientists don’t yet know exactly what that could be ...
