Astronauts aboard the International Space Station (ISS) have recently captured remarkable images of a rare atmospheric phenomenon known as a red sprite, observed above a thunderstorm in Texas. These transient luminous events (TLEs) occur high in the mesosphere, far above typical cloud formations, and manifest as brief, reddish flashes resembling upside-down jellyfish. According to NASA, red sprites can appear as high as 55 miles (90 kilometers) above the Earth's surface, making them a fascinating subject for scientists studying the dynamics of the upper atmosphere and its interaction with space weather.
