Is it possible not to notice the zipper? Surprisingly, the size of a zipper of about 60 kilometers was only noticed in 1989. The diameter of the beam such as a lightning can reach 100 kilometers. However, a brand new form of lightning was discovered by accident.
The existence of atmospheric electric discharges, different from the usual lightning predicted in 1925, Nobel Prize winner in 1927 Charles Wilson physics. But the first image of the sprite was obtained during tests done by physicists at the University of Minnesota with the help of an extremely sensitive camera, on July 6, 1989 only. .
In this picture, three of the images on the right are much less impressive than the Milky Way.
An extraordinary flash called sprites of the English word sprite in the translation of fairy or elf. Since their opening, they have received hundreds of pictures of sprites, halos on large sprites, resembling jellyfish, called elves (elves).
Seeing sprites without a camera is extremely difficult: they are not as bright as ordinary lightning, their duration is not more than a tenth of a second, and they only appear above the central regions with powerful storm fronts. an altitude of 50 to 100 kilometers.
The color of the sprite depends on the height at which it appears. At 70 km, it is red. At this altitude, the atmosphere is mainly composed of nitrogen, in which an electric discharge is red in color. The closer the Earth's surface is, the more oxygen there is, the color changes to blue, blue, and white. On closer inspection, it is obvious that sprites consist of a large number of plasma filaments.
Photo of a sprite above the distant storm, obtained from the ISS. The photo was taken on August 10, 2015. The bright spot on the surface of the Earth in the center of the frame – Dallas, through the greenish glow of the atmosphere long enough for the stars. The disc shining in the sky – the moon. The white glow of normal lightning and sprite visible to the left of the moon.
The videos of the appearance of sprites in the region of the Southern European Observatory will help to understand their nature.
