TL;DR

Astronauts aboard the International Space Station photographed a rare red sprite about 55 miles (90 km) above a Texas–Mexico border storm, one of several transient luminous events that flash for just milliseconds. The observation relies on the Atmosphere-Space Interactions Monitor (ASIM) with high-speed cameras up to 100,000 frames per second, and researchers are coordinating with JAXA's Light-1 CubeSat and ground networks to map where these high-altitude discharges occur and how they influence the upper atmosphere.
