Fermi Sees Antimatter-Hurling Thunderstorms

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. August 2012 celebrates the 80th anniversary of Carl Anderson's discovery of the positron, the antimatter counterpart to the electron. But what is antimatter, how can it be used -- and is it dangerous?
