Long-duration gamma-ray bursts are some of the most energetic events in the universe, releasing more energy in just a few ...

Researchers reported this week a deadly outbreak of plague in Siberia 5,500 years ago, revealing that Yersinia pestis evolved ...

A strange gamma-ray explosion that fired off repeated bursts from the same patch of sky over roughly seven hours has now been traced to its likely cause: a black hole ripping apart a star that strayed ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

A space explosion detected this summer burned for days on end, making it the longest and most unusual gamma-ray burst ever seen. Gamma-ray bursts are the universe’s most powerful explosions. They ...

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 ...

A flash of high-energy light from deep space has forced astronomers to rethink what they thought they knew about the most violent explosions in the universe. The event, a strange gamma-ray burst that ...

Massive stars end their lives as core-collapse supernovae, among which some extremes are broad-lined type Ic supernovae from Wolf–Rayet stars associated with long-duration gamma-ray bursts (LGRBs) ...

The product of a compact star merger is usually hypothesized to be a hyperaccreting black hole, typically resulting in a gamma-ray burst (GRB) with a duration shorter than 2 s. However, recent ...
