An astronaut aboard the International Space Station (ISS) has captured a stunning photo of glowing red lights in the Earth's atmosphere, known as "red sprites". These rare atmospheric phenomena were observed above thunderstorms off the coast of South Africa, offering a rare and intriguing glimpse into these elusive atmospheric phenomena.
According to a NASA press release, red sprites, are colourful bursts of energy that appear above storms as a result of lightning activity occurring in and below storms on Earth. They are brief, lasting only about a millisecond, but can be enormous, spanning up to 30 miles across. Unlike typical lightning bolts that descend from the clouds to the ground, a sprite behaves inversely, ascending into the atmosphere, resembling a form of reverse lightning.
''Super lucky a few weeks ago when shooting a timelapse of a lightning storm off the coast of South Africa. One of the frames in the timelapse had a red sprite. A rare event. My knowledge is pretty much just from Wikipedia but I want to know more,'' NASA astronaut Matthew Dominick wrote on X while sharing the image. The pic shows a stunning line of thunderstorms with a row of red sprites visible above the closest storm.

Crew members typically capture Transient Luminous Events (TLEs), including red sprites, with wide focal lengths during Earth timelapses. Instruments mounted outside the station, like Atmosphere-Space Interactions Monitor (ASIM), can capture a range of data for researchers on Earth using cameras, photometers, and X-ray and gamma-ray detectors.
Reacting to the image, one user wrote, ''That is an awesome picture. Thanks!''
Another commented, ''Phenomenal, that vertical height is really interesting, red can mean interaction with Oxygen.''
A third said, ''Wow thank you for posting this!! I often browse through the Gateway to Astronaut Photography page from NASA but I didn't see that one. Amazing you caught a sprite from the ISS.''
