On Dec. 14, 2009, while NASA's Fermi flew over Egypt,
the spacecraft intercepted a particle beam from a terrestrial gamma-ray
flash (TGF) that occurred over its horizon. Fermi's Gamma-ray Burst
Monitor detected the signal of positrons annihilating on the spacecraft
-- not once, but twice. After passing Fermi, some of the particles
reflected off of a magnetic "mirror" point and returned. Credit: NASA's

(PhysOrg.com) -- Scientists using NASA's Fermi
Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before.
