The International Space Station specked a blue jet, which is a foreign kind of lighting. Blue jets usually run upwards into the stratosphere from the thunderclouds. They move at a very high speed, sometimes going up to altitudes of 50KM within a second. It is essential to note that blue jets stimulate stratospheric nitrogen to make their style blue color. In contrast, typical lighting elicits a mixture of gases at the bottom of the atmosphere to smoulder white.

For many years, people have been observing blue jets right from the ground and aircraft, though one cannot explain how they are formed without going high beyond the clouds. On 20th January, researchers from the International Space Station reported that they had seen blue jets emerging from a vast, bright power burst at the top of the thundercloud.

Victor Pasko, Penn State-space physicist, said that having a better understanding and knowledge about blue jets and other upper-atmosphere occurrences associated with thunderstorms like elves and sprites is very crucial.  This is because these incidents have the ability to affect how radio waves move through the air. This can potentially interfere with the communications technologies. Pasko did not participate in the research.

The blue jet was captured by cameras and light-sensing instruments known as photometers on the space station. In February 2019, the blue jet was seen in a storm above the Pacific Ocean, close to the Island of Nauru.  Torsten Neubert, a physicist at the Technical University of Denmark in Kongens Lyngby, said that the entire event started with something like a blue bang, which was a blue light close to the top of the cloud and existed as a flash in 10-microsecond. This happened about 16KM above the sky. The blue get then goes up at a very high speed into the stratosphere from the flashpoint. It moves high to around 53KM in multiple hundred milliseconds.

Neubert said that there is a possibility that a spark that produced the blue jet must have been a different short-range electric discharge in the inner of the thunderstorm. On the other hand, ordinary lightning bolts are created by discharges between the opposite sides of the cloud’s charged regions. It is also formed by a cloud and the ground, which are hundreds of kilometers apart. Neubert said that very short but strong electric current bursts can be created by turbulent mixing in a high cloud in oppositely charged regions, which is about a kilometre from each other. Many researchers have seen such strong, short-range discharges.
