Astronauts on the ISS captured a rare red sprite above a storm near the Texas-Mexico border.
Red sprites, triggered by intense thunderstorm electricity, are fleeting atmospheric events.
The ASIM instrument on the ISS helps scientists study these events and their impact on the ionosphere.
ISS captures rare atmospheric phenomenon: red sprite
Astronauts aboard the International Space Station (ISS) have captured images of a rare atmospheric phenomenon known as a red sprite, which appeared above a storm system near the Texas-Mexico border. These transient luminous events (TLEs) occur high above thunderclouds, in the mesosphere, and last only milliseconds, making them difficult to observe from the ground. Red sprites, along with other TLEs such as blue jets and ELVES, are triggered by intense electrical activity in thunderstorms. The Atmosphere-Space Interactions Monitor (ASIM) on the ISS, installed by the European Space Agency, continuously observes these events using high-speed cameras and photometers. These instruments have revealed how lightning at the tops of storm clouds can release electromagnetic energy into the ionosphere, creating ELVES that spread across hundreds of miles and alter the electrical charge of the upper atmosphere.
