radioweather writes: Scientists using NASA's Fermi Gamma-ray Space Telescope have detected beams of antimatter from thunderstorms in the form of positrons hurled into space. Scientists think the antimatter particles were formed in a terrestrial gamma-ray flash (TGF), a brief burst produced inside thunderstorms and shown to be associated with lightning. "These signals are the first direct evidence that thunderstorms make antimatter particle beams," said Michael Briggs, a member of Fermi's Gamma-ray Burst Monitor (GBM) team. He presented the findings at a news briefing at the American Astronomical Society meeting in Seattle. As the late, great, Johnny Carson of the Tonight Show used to say, “That is some weird, wild, stuff“.
