Gamma-ray bursts (GRBs) are intense, transient cosmic events, typically originating from massive stellar collapses or mergers of compact objects, which serve as crucial probes for understanding the ...

The longest gamma-ray burst ever recorded did not roar for seconds or even minutes, but for a staggering seven hours, forcing ...

Gamma-ray bursts are the most powerful explosions in the universe. They emit most of their energy in gamma rays, light which is much more energetic than the visible light we can see with our eyes. In ...

July 25 (UPI) --Scientists have announced a never-before-seen energy peak that resulted from the largest gamma ray burst in history, NASA announced Thursday. The brightest-of-all-time gamma ray burst, ...

Gamma-ray bursts (GRBs) are intense bursts of gamma radiation, typically generating more energy in a few seconds than the sun will produce over its ten-billion-year lifetime. These transient phenomena ...

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 ...

Researchers at the University of North Carolina at Chapel Hill have contributed to new insights into the most long-lived cosmic explosion ever recorded. The event was a gamma-ray burst that remained ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

A cosmic explosion that lasted seven hours: this is the unusual spectacle recently observed by astronomers. Named GRB 250702B ...

This artist's impression shows two tiny but very dense neutron stars at the point at which they merge and explode as a kilonova. Such a very rare event is expected to produce both gravitational waves ...
