Scientists observe Blue Jet Lightning from Space

Kathmandu. January 27. Scientists have recently observed a mysterious upward shooting “blue jet” lighting in the stratosphere followed by diverging UV emissions “elves”.
In the research article published in the journal “Nature”, the scientist have described that on February 26, 2019,. the Atmosphere–Space Interactions Monitor (AISM) fitted into the International Space Station (ISS) detected five intense blue flashes of approximately 10-microsecond, sparked from a thunderstorm cell above the central Pacific Ocean. AISM is an instrument composed of three photometers and two cameras, that is used to detect flashes of electric discharges from space.
Blue jets are atmospheric electric discharges of several hundred millisecond duration that fan into cones as they propagate from the top of thunderclouds into the stratosphere. Scientists believe that the blue jets initiate an electric breakdown between the positively charged upper region of a cloud and a layer of negative charge at the cloud boundary and in the air above.
The blue jet was followed by ‘elves’ at the bottom of the ionosphere.
