In November 2024, gravitational-wave detectors recorded the violent merger of two black holes billions ...

Gamma-ray bursts are the most violent explosions in the universe. In a fraction of a second, they can release more energy than the sun will emit across its entire 10-billion-year lifetime. Most are ...

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated ...

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

A tremendous cosmic explosion 2.4 billion light years away temporarily changed the electric field in Earth’s ionosphere (the electrically-charged upper layer of our atmosphere that helps shield life ...

"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 ...

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 ...

An astounding gamma-ray burst, dubbed GRB 221009A, continues to amaze even though it has been more than a year since it was detected. Scientists from Italy have recently published a study that shows ...
