Space Station Captures the Sky’s Hidden Lightning Parade

Astronauts aboard the ISS use high-speed cameras and the Atmosphere–Space Interactions Monitor to document rare high‑altitude lightning—blue jets, red sprites and ELVES. The observations shed light on how transient luminous events affect radio communications, aviation safety and upper-atmosphere chemistry, and future CubeSats like Light‑1 aim to map gamma-ray flashes and other TLEs for better forecasting.
