Last week, an astronaut aboard the International Space Station was struck by lightning over Europe. But unlike most lightning, this electric explosion It was not a group of thorny tendrils but rather a large blue bubble above the continent.
The “transient flare event, “ Also known as upper atmosphere lightning, it was spotted in a time snapshot taken by French astronaut Thomas Pesquet. This is amazing Type of lightning different from flashes That occur In and below storm clouds and leans to be much greater.
There are sprites, which are ultra-bright vertical flashes of red or bluish-green light; jets, which tend to be blue in color and are found in the stratosphere; and elves, which are high-altitude electromagnetic pulses. There is, too trolls, which resemble jets, and other magically-named luminous forms of lightning that occur above the clouds.
The colors of various phenomena are formed from the atmosphere; On Earth, nitrogen makes sprites look red, but on Jupiter, an atmosphere is rich in hydrogen That would make the goblins blue.
Since 2018, it has become ASIM تجربة Experience Aboard the International Space Station I noticed these forms of giant lightning. that it The successor to the previous THOR experiment proposed by Danish astronaut Andreas Mogensen, who captured blue planes and red sprites on video over the Bay of Bengal in 2015.
These forms of lightning are extremely short, so the researchers had to go back through Mogensen’s shots frame by frame to pick out certain phenomena. Similarly, Pesquet’s image of the last transient illuminated event was extracted from a longer time shot of the night sky.
in a comment for new picture Posted onlinePesquet noted that the International Space Station is well positioned to photograph such phenomena, as it flies above the equator, where more thunderstorms occur. This particular event appeared somewhere in southeastern Italy, as the photo shows.
He wrote: “What is so impressive about this lightning is that it was only a few decades ago that it was spotted by pilots and scientists weren’t convinced that it actually existed.” Fast forward a few years and we can confirm that elves and orcs are very real and can affect our climate as well!
