Searching for Red Sprites
The elusive red lightning called sprites last less than a second. They form above the tops of thunderclouds, when lightning bolts trigger a burst of red light in electrically charged particles.
Because the storms that birth sprites also hide them from view, few sprites are seen from the ground. To better understand the phenomenon, scientists are hunting red sprites from the air.
University of Alaska, Fairbanks, graduate student Jason Ahrns captured stunning images of red sprites during several flights over the Midwest during the 2013 summer aboard the National Center for Atmospheric Research’s Gulfstream V research plane.

High-speed video and models suggest sprites are caused by plasma irregularities in the ionosphere, the layer above the lower atmosphere.
This is a photograph of five plasma irregularities responsible for sprite initiation.

Sprite Seen by Astronauts
Red sprites, or seemingly mystical electrical flashes in the atmosphere, are connected to thunderstorms and lightning. This red sprite was captured from astronauts aboard the International Space Station traveling southeast from central Myanmar to north of Malaysia on April 30, 2012.
