Elusive Red Sprite
For nearly 100 years, military and civilian pilots reported seeing ephemeral flashes above storms. While atmospheric scientists mostly discounted these claims, a photo taken in 1989 accidently captured on film the first image of these short-lived bursts called red sprites. As rain and lightning descend from thunderstorms, electrical discharges can be unleashed into Earth's ionosphere. Resembling long, jellyfish-like tendrils, red sprites shoot above the tops of clouds in bright red spurts and last only milliseconds. Astronauts aboard the International Space Station were recently lucky enough to capture one on camera. Watch the video to see a red sprite explode above a large lightning flash in April 2012.
Astronauts capture a rarely photographed atmospheric light show.
Try to spot the red sprite as the International Space Station travels above Southeast Asia. Hint: Look around 0:06.
A red sprite (circled) appears and just as quickly disappears as seen in this sequence.
Red sprites occur above thunderstorm clouds and are related to lightning, but how they form is not yet fully understood.
This image by University of Alaska-Fairbanks researchers was one of the first photographs of a red sprite ever taken.
