NASA Captures Rare “Atmospheric Sprite” Over Mexico, Offering New Insights into Electrical Phenomena
A stunning image of an atmospheric sprite, a rare and elusive electrical discharge, was recently captured by an astronaut aboard the International Space Station (ISS) over Mexican territory near the U.S. border. This observation provides valuable data for scientists studying these enigmatic events and their impact on our atmosphere.
Understanding Transient Luminous Events
Sprites, more formally known as transient luminous events (TLEs), are brief, colorful electrical discharges that occur high above thunderstorms. Unlike conventional lightning, which travels from the clouds to the ground, sprites ascend from the tops of storm clouds, reaching altitudes between 50 and 90 kilometers within the mesosphere. They manifest as branching, reddish or bluish structures, sometimes extending up to 96 kilometers above the storm.
“Just. Wow. As we went over Mexico and the U.S. this morning, I caught this sprite,” astronaut Nichole Ayers, known as “Vapor” on social media, wrote in a post accompanying the image.

Why Mexico?
The unique geographical and meteorological conditions of Mexico make it a prime location for observing sprites. The region experiences a high frequency of convective thunderstorms, the powerful storms that trigger these upper-atmospheric phenomena. The ISS provides an unparalleled vantage point for observation, allowing scientists to view sprites above the cloud cover that often obscures them from ground-based observers.
A Long-Standing Mystery
Sprites were first photographed in 1989, yet they remained largely unstudied for decades due to their fleeting nature and high altitude. Pilots had previously reported seeing unusual light phenomena above thunderstorms, but confirming these observations required the unique perspective offered by space-based platforms.
According to Ayers, images of sprites are crucial for improving our understanding of their formation, their connection to storm activity, and their influence on the upper atmosphere. This data also contributes to refining weather and atmospheric electrical activity models.
NASA’s “Spritacular” Project
Ayers’s recent image directly supports NASA’s “Spritacular” project, an initiative dedicated to collecting and analyzing images of these transient luminous events. The project aims to build a comprehensive database of sprite observations, furthering research into these complex atmospheric processes.
The recent image represents a significant contribution to atmospheric science and the ongoing effort to unravel the mysteries surrounding these electrical phenomena. .
