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 ...

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 ...

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

COLUMBIA, S.C. (WIS) - Gamma-ray bursts are a relatively new discovery in space science. The first burst was discovered in the late 1960s. You might be wondering ...

Gamma-ray bursts are a relatively new field in space science. The first was discovered in the late 1960s, and in the nearly six decades since, there’s never been a discovery quite like this. It may ...

In 2023, astronomers using NASA’s Chandra X-ray Observatory and Hubble Space Telescope spotted an unusual class of short gamma-ray bursts, whose origin appeared to be the collision of two neutron ...

"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, powerful glares of high-energy that wash through the Universe once every day or so are, for a brief time, the brightest objects in the gamma-ray sky. ESA’s Integral gamma-ray ...
