The dying star emits high energy radiation as gamma rays. Gamma rays are a form of electromagnetic radiation with wavelengths much shorter than light waves, meaning they’re invisible to the ...

A new study has found that an explosion in virus diversity 2.5 million years ago in Lake Tanganyika occurred at the same time radiation from an ancient supernova bathed Earth in cosmic rays.

A new suggests the universe may rotate—just extremely slowly. The finding could help solve one of astronomy’s biggest puzzles.

opening the possibility that the gamma ray burst it would unleash upon exploding could barrage our planet with deadly radiation in the not-so-distant — on a cosmic scale, at least — future.

A Radiolab podcast that aired in May revealed how tiny, charged particles violently expelled from exploding stars beyond our solar system - otherwise known as cosmic radiation - hit the Earth and ...

like exploding stars. A modified version of that theory is widely considered likely, but there is no direct evidence yet. Meanwhile, Prof. Willard Libby deduced that cosmic radiation would affect the ...
