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 ...

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 ...

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 ...

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

A multi-sensor detection of an intense gamma-ray flash, which occurs when two lightning leaders collided, has been observed. Observations across a wide radiation spectrum enabled precise measurement ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. On October 9, 2022, astronomers detected a big bang. But while not ...

A team of astronomers have observed an explosion in the universe unlike any ever witnessed before. The gamma-ray bursts from outside the Milky Way galaxy repeated several times over the course of a ...

It's nicknamed the "Brightest Of All Time," or the "BOAT," for good reason. Astronomers have re-examined the biggest explosion ever seen, possibly the most massive explosion since the Big Bang, to ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

"If this is a massive star, it is a collapse unlike anything we have ever witnessed before." Astronomers have spotted a cosmic explosion of high-energy gamma-rays unlike any ever seen before. The ...
