This week, scientists say they've discovered antimatter beams shooting above thunderstorms, a never-before seen phenomenon.
"These signals are the first direct evidence that thunderstorms make antimatter particle beams," said Michael Briggs of the University of Alabama in Huntsville
The antimatter beams were detected from aboard NASA's Fermi Gamma-ray Space Telescope
. Acting like enormous particle accelerators, the storms emit terrestrial gamma-ray flashes, called "TGFs," along with high-energy electrons and positrons. Scientists now think that most TGFs produce particle beams and antimatter.
