The most extreme fireworks in the universe are supposed to follow rules. Gamma-ray bursts, the brightest explosions known, ...

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 ...

Scientists have pinned down the energy produced by an unusually bright gamma-ray burst detected in 2022, and wow is it a whopper. Reading time 2 minutes The gamma-ray burst, affectionately dubbed ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous ...

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 simulation showing how the merger of a black hole and a neutron star can generate powerful jets and winds that produce gamma-ray bursts. A new study presents a framework linking the physics of such ...
