Instead, they are a rare form of high altitude lightning, known as sprites, that briefly flare above powerful thunderstorms.
The photographs were shared through NASA’s citizen science project ‘Sprictacular’, revealing a quick flash of red light hovering above a storm cloud.
The moment lasted only a second, yet it displayed one of the most enigmatic electrical events in Earth’s atmosphere.
Sprites form far above thunderclouds, in the thin, fragile layers of the upper atmosphere. Their upper branches glow a deep, fiery red, while the lower tendrils fade into a bluish network of streaks, resembling delicate roots reaching downward.
These events, officially called Transient Luminous Events (TLEs) were once little more than rumors. For decades, pilots reported seeing brief red glimmers above storms, but it wasn’t until 1989 that the first clear image was captured.
Since then, astronauts and ultra fast cameras have revealed their true complexity, unpredictable patterns, and surprising frequency.
On July 3, 2025, NASA astronaut Nicole Ayers, observing from the International Space Station (ISS), recorded a brilliant light column plunging toward Earth one of the most striking sprite displays witnessed from orbit.
In another astonishing event, two photographers documented 105 towering red columns near Lake Pumoyong Tso in southern Tibet on May 19, 2022, marking the largest sprite outbreak ever recorded.
Scientists emphasize that these pillars of light are fully natural electrical phenomena, not cosmic warnings. They appear for mere seconds but leave a lasting impression, offering researchers and sky watchers a renewed sense of wonder.
With each new sighting, sprites continue to remind us that Earth’s skies hold secrets, fleeting, beautiful, and waiting to be understood.
