Images (pictured) of gamma rays flashes from thunderstorm, captured by Fermi space telescope. Scientists believe this may occur up to 500 times daily. The Daily Galaxy article explains, “a space telescope has accidentally spotted thunderstorms on Earth producing beams of antimatter. Such storms have long been known to give rise to fleeting sparks of light called terrestrial gamma-ray flashes. But results from the Fermi telescope show they also give out streams of electrons and their antimatter counterparts, positrons.” A YouTube video from NASA, “Terrestrial Gamma-ray Flashes Create Antimatter,” is rewarding three minutes.
