Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block. When you purchase through links on our site, we may earn an affiliate ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA explains. Credit: NASA Goddard Space Flight Center ...

Thunderstorms are far more radioactive than previously thought, routinely producing gamma rays—the highest-energy form of electromagnetic radiation typically associated with supernovas and other ...

There’s a ton of bizarrely-bright light shooting out of the Sun, scientists say — and it’s been happening for years, right under our noses. Astronomers out of Michigan State University have not only ...

We have previously reported on life span shortening as well as increased incidence rates in several neoplasms in B6C3F1 mice that were continuously exposed to 21 mGy/day of gamma rays for 400 days. To ...

A small, dense star chowing down on its enormous dying neighbor caused a massive explosion that generated some of the highest-energy gamma-rays ever observed for a nova. The nova system, called RS ...

Above the cloud tops, thunderstorms throb with a complex, frenetic light show of high-energy radiation. A view from a retrofitted spy plane soaring at 20 kilometers up revealed storms glowing and ...
