Red sprites

Référence de la vidéo 12080887
Low light footage of a thunderstorm with red sprites. Red sprites are faint high-altitude electric discharges. They are triggered by positive cloud-to-ground lightning in the storm below. They can rise to heights of 97 kilometres, reaching the bottom of the ionosphere and the edge of space. They last for a few thousandths of a second, and are only visible under the right conditions. Their existence was only confirmed in 1989 and their formation is still not fully understood. The thunderstorm, in Kansas, USA, was filmed from Colorado, USA.
