For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a terrestrial gamma-ray flash (TGF). Researchers at the University of Osaka ...

The event began with the approach of two opposing electrical discharges: a downward-propagating leader from a thundercloud and an upward leader emerging from a television transmission tower in ...

A multi-sensor detection of an intense gamma-ray flash, which occurs when two lightning leaders collided, has been observed. Observations across a wide radiation spectrum enabled precise measurement ...

A rare and extraordinary event has been captured by researchers in Japan, revealing that lightning on Earth can produce gamma-ray bursts—high-energy emissions typically observed from cosmic phenomena ...
