A rayof intense blue colorwas captured by the cameras of the International Space Station (ISS for its acronym in English), this unique phenomenon that can rarely be seen from the surface of the Landit lasted only a few seconds and only the station crew members were able to live live.
He strange lightning of an intense blue color, which was captured by optical cameras and photometers, added to the X-ray and gamma detectors that the Space Station has, the International Space Station was seen from more than 400 kilometers high and was produced from the clouds of a storm that propelled it into our atmosphere.
The images that were published in the scientific journal sciencenewsthey are about electric shocksLightning-like s of several hundred milliseconds in duration that break out into cones as they propagate from the tops of storm clouds toward the stratospherethe scientists explain.
The publication explains that these good heavens They are capable of reaching up to 50 km from the stratosphere and have a duration of less than a second, the blue color they emit is a product of the fact that the light they extract comes mainly from stratospheric nitrogen.
“For the first time in history, a blue ray has been detected and characterized with all its geometry, from the first microsecond of its genesis to its propagation above the clouds in the stratosphere”, the scientists indicated.
Why did this strange blue lightning occur?
According to scientists who study this freakthis occurs due to a electric shock of short range that takes place inside the clouds of the storm and that performs the functions of a spark that activates these flashes.
These types of events are also known as “blue jets” They have been sighted in 1994, 1995 and 2019, the last time five of these discharges were documented in a storm that developed over the Pacific Ocean.
Now researchers from different countries such as Denmark, Norway and Spain have detected and characterized for the first time the complete form of one of these blue rays, determining its position, duration, evolution and speed from its origin in the upper layer of the clouds.
