Thunderstorms shoot out antimatter (believe it or not)

A lighting associated phenomenon in thunderstorms, called a terrestrial gamma ray flash, results in beams of antimatter shooting into space. The phenomenon was discovered by NASA's Fermi satellite.
Tell me if NASA's release sounds like science fiction: "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."
COMMENT: You know, sometimes even I'm at a loss for words.
