Gamma Rays Come from the Earth Too (http://www.universetoday.com/am/publish/gamma_rays_earth.html?2322005)


Scientists were surprised a few years ago when the Compton Gamma Ray Observatory discovered bursts of gamma rays weren't only coming from deep space - some are coming from the Earth too. Further observations from NASA's RHESSI satellite has shown that approximately 50 Terrestrial gamma-ray flashes (TGFs) emanate from our planet every day, blasting out gamma rays for about a millisecond. What causes these TGFs is still unknown, but scientists believe they're caused by the build-up of electrical charge at the tops of thunderclouds.
