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 can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block. Gamma rays are high-energy photons produced by some of the most violent ...

Thunderstorms are known to generate gamma rays, the highest energy radiation on Earth. But pinning the burst to a specific bolt is new.

The most powerful explosions in the known universe come from what are known as gamma-ray bursts — though they may not sound particularly exciting, scientists usually speak about these incredible ...

In a record-breaking discovery, scientists detected our very own sun emitting an extraordinary amount of gamma rays — wavelengths of light known to carry the most energy of any other wavelength ...

For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a terrestrial gamma-ray flash (TGF). Researchers at the University of ...
