NASA astronaut Nichole Rhea Ayers captured a rare and striking atmospheric phenomenon known as a "gigantic jet" or "sprite" from the International Space Station (ISS) while orbiting approximately 250 miles above Earth. This phenomenon, classified as a type of Transient Luminous Event (TLE), occurs in the upper atmosphere, specifically in the mesosphere at altitudes ranging from 50 to 130 kilometers. Unlike typical lightning that strikes downward, gigantic jets are powerful electrical discharges that shoot upward from thunderstorm tops, sometimes reaching nearly 100 kilometers in height and forming bright branching structures. The photographed event occurred over the region near the Texas-Mexico border, including areas over Mexico and the southern United States, such as the Desert Southwest. These events are rare, fleeting, and not well understood, with durations of about 100 milliseconds and are nearly invisible from the ground. The image captured by Ayers is considered one of the clearest and most detailed photos of such a phenomenon taken from above. The observation contributes to ongoing research into the nature of TLEs, which are triggered by intense electrical activity in thunderstorms and involve discharges of cold plasma in the upper atmosphere. The photo also shows the glow of major Texas cities including Dallas, Austin, San Antonio, and Houston beneath the storm. This rare capture provides valuable insight into atmospheric electricity and the complex interactions occurring between thunderstorms and the upper atmosphere.
