What is this mysterious blue light captured by Thomas Pesquet from space?

Space, unusualubled le, updated

The French Station Thomas Pesquet shared an incredible image of the ISS space station.

As Thomas Pesquet explains, "This photo is extracted from a series taken during a timelapse above Europe.Luckily, she shows a flash and sprites in the upper atmosphere!These light phenomena are rare and very short, which makes them difficult to photograph and study.The international space station is equipped with an instrument dedicated to their observation ".

What the French Station has managed to immortalize is therefore a transient luminous phenomenon (transient lumous event or tle in English), sometimes called "sprites" or sylphs, and which consists in the formation of light lightning visible in the upper atmosphereand accompanying thunderstorms.TLE are optical fluorescence phenomena, caused by electrical discharges during underlying thunderstorms.They generally last between less than a millisecond and more than 2 seconds.

These phenomena are still little known, as well as their dangerousness for aircraft, especially spacecraft."The ISS is particularly suitable for these observations because it flies up several times a day the equator where there are the most storms.Something fascinating about these lightnings is that they stayed in the legendary for decades, told by pilots, and scientists were not convinced of their existence.We now know that sprites, elves and other blue or giant jets really exist and that they could have an influence on the climate, "continues Thomas Pesquet.
