"Space Explorer Captures Rare Celestial Phenomenon"

European Space Agency astronaut Andreas Mogensen has captured an image of a rare electrical discharge known as a red sprite, or transient luminous event (TLE), from the International Space Station's Cupola observatory module. TLEs, which occur between 40 and 80 kilometers above the Earth, are rarely seen from the surface and are caused by a build-up of electrical charge within clouds. The study aims to better understand how lightning in the upper atmosphere affects greenhouse gas concentrations.
