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 ...

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 ...

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.

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

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 ...

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.

This represents the highest energy spectral line feature ever emitted by celestial objects in the universe. The scientists have also discovered that the gamma-ray line follows a power-law function ...

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 ...

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 ...
