A groundbreaking scientific discovery unravels the mystery surrounding the nature of lightning, which could change our understanding of atmospheric electrical phenomena. A leading research team from Penn State University, led by Prof. Victor Pasko, presented a revolutionary model of electronic processes in thunderclouds.
Scientists found that extremely strong electric fields generate a cascade effect resembling an electronic "pinball", where electrons are accelerated to remarkable speeds. Upon collision with atmospheric molecules, they cause ionization chains that generate additional electrons and X-ray radiation.
The study, published on August 4, 2025, also sheds light on the mysterious phenomenon of "dark lightning" - gamma-ray eruptions without visible light and sound. The discovery has the potential to improve meteorological warning systems and aviation safety by providing unprecedented insight into electrical atmospheric processes.
