Fermi Terrestrial Gamma-ray Flash (TGF) Animations

Released on January 10, 2011
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.

Animation of cloud of electrons and positrons following a magnetic field line and striking the Fermi spacecraft, causing it to emit gamma rays. The cloud then returns along the same line and strikes the spacecraft again.
