Sprite lightning (or red sprites) are brief, reddish flashes of light that erupt high above thunderstorms in the mesosphere, appearing as jellyfish or columns, triggered by powerful positive cloud-to-ground lightning strikes below. These Transient Luminous Events (TLEs) occur 30-50 miles up, lasting milliseconds, making them hard to see but captured by cameras, revealing complex structures of ionized air excited by the electric field, similar to auroras.
