NASA astronaut Nichole Rhea Ayers aboard the International Space Station (ISS) captured rare and striking images of upper-atmospheric lightning phenomena known as sprites and gigantic jets during orbits over Mexico and the United States. Sprites, also called Transient Luminous Events (TLEs), are brief, red electrical discharges occurring high in the mesosphere at altitudes between 50 and 130 kilometers, often triggered by intense electrical activity in thunderstorms below. These luminous events can extend up to 60 kilometers in length and are not well understood due to their rarity and fleeting nature. In addition to sprites, Ayers photographed a gigantic jet, a powerful type of electrical discharge that rises nearly 100 kilometers from thundercloud tops to the edge of space, forming bright branching structures. The gigantic jet image notably shows a storm hovering near the Texas–Mexico border, with visible city glows from Dallas, Austin, San Antonio, and Houston. These observations provide valuable visual data on rare atmospheric electrical phenomena and contribute to ongoing research into thunderstorm-related upper-atmospheric events.
