For almost 100 years, pilots have been seeing incredible flashes above storms. Scientists couldn’t really explain it until the first photo proving it in 1989. As a storm rages below on Earth, the electrical discharge above the clouds interacts with the ionosphere. The can look like anything from pillars to cones, or even tentacles of a jellyfish, but only last for fractions of a second.
Thanks to our space program, NASA has helped uncover this mystery even in the post Space Shuttle era with continuous monitoring on the International Space Station.
