Story summary

In a groundbreaking study from the University of Osaka, researchers captured terrestrial gamma-ray flashes (TGFs) during a lightning event, revealing that these flashes are tied to accelerated electrons in powerful electric fields. Remarkably, the gamma burst was detected just 31 microseconds before the lightning strike, deepening our understanding of lightning's energy dynamics and its cosmic connections.
