Latest Upper-atmospheric lightning Stories
Do giant flashes of lightning striking upwards from thunder clouds merely pose an extraordinarily spectacular view? Or do they actually alter the chemical composition of the atmosphere, playing a role in ozone depletion and the climate on Earth? This is the key question that may be answered by specially designed cameras, which ESA proposes to place on board the International Space Station.
Giant red blobs, picket fences, upward branching carrots, and tentacled octopi -- these are just a few of the phrases used to describe sprites -- spectacular, eerie flashes of colored light high above the tops of powerful thunderstorms that can travel up to 50 miles high in the atmosphere.
An unprecedented flash observed by the space shuttle Columbia crew in 2003 over the Indian Ocean may be a new type of transient luminous event, like lightning sprites, but one that is not necessarily caused by a thunderstorm. The discharge was observed less than two weeks before the shuttle was lost during its Earth reentry.
