LIGHTNING AND TERRESTIAL GAMMA-RAY FLASHES

FROM:  NASA
Fermi's GBM Finds Radio Bursts from TGFs



Lightning in the clouds is directly linked to events that produce some of the highest-energy light naturally made on Earth: terrestrial gamma-ray flashes (TGFs). An instrument aboard NASA's Fermi Gamma-ray Space Telescope was recently fine-tuned to better catch TGFs, and this allowed scientists to discover that TGFs emit radio waves, too.
