Alien signal or atmospheric mystery? NASA reveals truth behind red ‘jellyfish’ lights and sprites over Earth

{}Mysterious red lights falling from space, initially thought to be alien signals, have been identified by scientists as red sprites. These rare upper-atmosphere lightning phenomena occur high above thunderstorms, appearing as upward-traveling pillars or jellyfish-shaped glows. Captured by citizen scientists and astronauts, these striking electrical events are triggered by powerful ground lightning strikes.
