A single gamma-ray burst has forced astronomers to redraw their mental map of how the most violent explosions in the universe ...

The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for ...

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 ...

Astronomers using the James Webb Space Telescope report that a powerful gamma-ray burst detected in March may have been produced by the explosion of a massive star just 730 million years after the Big ...

CAPE CANAVERAL, Fla. (AP) — Scientists have discovered a gamma ray explosion outside our galaxy that’s not only exceptionally powerful, but also long-lasting. Telescopes on Earth and in space — ...

Astronomers used major telescopes across the world to probe a cosmic explosion 8 billion light-years from the solar system.

Astronomers tracked a gamma-ray burst lasting over 7 hours, unseen in visible light, from a dusty galaxy 8 billion light-years away, challenging existing models and raising new questions for science.

This unique gamma-ray source will generate a beam of gamma rays like those that existed in the first minutes of our universe after the Big Bang. The high-flux, monochromatic and energy-tunable gamma ...

Because dark matter is completely invisible to light, science had to look for clever new methods to spot it.

It’s the greatest cosmic murder mystery of the year: How did a black hole destroy a star—and what kind of black hole is the culprit? Normally, so-called “gamma ray bursts,” sudden flashes of extremely ...
