Gamma rays are high-energy photons produced by some of the most violent events in the universe. We explore this powerful radiation in more detail here.

Scientists have discovered that the Sun produces higher energy light than was thought possible. An unusual type of telescope detected gamma rays with energies of over 1 tera electron volt, at ...

When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown.

In the 1990s, NASA scientists got an unexpected surprise. While scanning the cosmos for high-energy gamma radiation bursts from supernovas and black holes, they stumbled upon a curious finding.

Invisible to our eyes, gamma rays burst from supernova explosions as well as the hottest and most energy dense objects in the cosmos, like pulsars, those highly magnetized neutron stars that emit ...

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

The gamma-ray burst, named GRB 221009A, is thought to have caused huge variations in the electrical field of the Earth's ionosphere at a height of around 310 miles above the ground, according to a ...

This study uncovers terrestrial gamma-ray flashes produced by lightning, offering new insights into Earth's powerful atmospheric radiation events and their origins. The post Gamma-Ray Flashes ...

Gamma rays belong to the same family as light, x-rays, and the radio waves that travel between a radio station and your car radio. Called electromagnetic radiation, such waves travel at the speed ...

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 ...

A new class of composites with tunable microstructures offers better shielding from neutron and gamma radiation.

For years, astronomers puzzled over the mystery of where the heaviest elements in the universe—like gold, uranium, and platinum—come from. Scientists understood that these elements had to form under ...
