Normally when people think of gamma rays -- bursts of an incredibly high-energy form of light -- they are coming from out of this world, such as solar flares, exploding stars or black holes.

Get Instant Summarized Text (Gist) Cosmic-ray showers, consisting of high-energy particles from space, appear to play a significant role in triggering lightning flashes. Observations using a 3D ...
