Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

To reduce the strength of incoming gamma rays by a billion, you need 13.8 feet (4.2 meters) of water, 6.6 feet (2 m) of concrete or 1.3 feet (0.39 m) of lead, according to the radiation protection ...

The circle in the middle of the trefoil represents an atom and the blades represent the three common types of ionizing radiation emanating from it — alpha (α), beta (β) and gamma (γ). The symbol was ...

Gamma rays are the most energetic form of electromagnetic radiation. In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.

For context, one of those visible wavelengths carries an energy of about 1 electron volt. The gamma rays Nisa and fellow researchers witnessed, by contrast, exuded about 1 trillion electron volts.

Astronomers have discovered the highest-energy light rays ever observed from the sun in a finding that raises more questions on how such radiation is emitted from its solar atmosphere.. Since the ...

Gamma-ray producing storms “There is way more going on in thunderstorms than we ever imagined,” said Cummer. “As it turns out, essentially all big thunderstorms generate gamma rays all day ...

A new study suggests that explosive events in space have the potential to temporarily switch off the natural shield that protects us from harmful solar radiation. By Katrina Miller On Oct. 9, 2022 ...

Blasts of gamma rays from the distant universe may provide a new way to measure cosmic distances. These gamma ray bursts (GRBs) could help us understand the structure and expansion of the universe.

Researchers had observed two forms of thunderstorm gamma-ray emissions: relatively long-lived “glows” lasting hundreds of seconds, as well as intense, microsecond-scale bursts known as ...
