Gamma-ray bursts are the most powerful explosions in the universe, a million trillion times as bright as the sun, and scientists just observed one up close. Skip to main content Menu ...

The origin of a mysterious gamma-ray source has been identified thanks to the donated computer power of thousands of volunteers.

Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block.

Shrouded in mystery for decades, gamma-ray bursts are the brightest explosions since the Big Bang and emerge from only the most violent cosmic events.

A huge surge of gamma-ray energy from space caused electric currents to flow through the surface of the Earth on October 9, scientists have said.. This gamma-ray burst, named GRB221009A, is the ...

We are also creating a table of the past gamma-ray bursts and the observations of the ozone layer and trying to see if they match,” he said. Nature Communications, 2023. DOI: 10.1038/s41467-023 ...

"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 ...

This gamma ray conversion, astrophysicist Tim Linden said, probably takes place 100 to 1,000 kilometers below the sun’s surface, where the magnetic field is strong enough to turn the cosmic rays ...

Gamma-ray bursts come in two flavors, long and short. The former, which can last up to several minutes or so, are thought to result from stars more than 20 times the mass of our sun collapsing ...

Thousands of gamma-ray bursts have been studied for more than 40 years. Because of its proximity, GRB130427A generated more gamma-rays, over a longer time and at higher energies, than any detected ...

A gamma ray packs at least 10,000 times more energy than a visible light ray. Unlike the Incredible Hulk , gamma rays are not green — lying as they do beyond the visible spectrum, gamma rays ...

So gamma rays are photons that pack a serious punch. Creating gamma ray photons obviously takes a lot of energy. We're talking nuclear fusion and fission or extremely high magnetic fields.
