Description

NASA's Fermi Gamma-ray Space Telescope has detected beams of antimatter launched by thunderstorms. Acting like enormous particle accelerators, the storms can emit gamma-ray flashes, called TGFs, and high-energy electrons and positrons. Scientists now think that most TGFs produce particle beams and antimatter. More information on this topic available at: http://www.nasa.gov/mission_pages/GLAST/news/fermi-thunderstorms.html Description: Terrestrial Gamma-ray Flashes produce high-energy electrons and positrons. Moving near the speed of light, these particles travel into space along Earth's magnetic field.
