The special type of lighting is hard to spot from the ground because it sprouts towards the heavens from above thunderclouds.
A peculiar atmospheric phenomenon that involves lightning stabbing upwards rather than downwards as was observed by scientists aboard the International Space Station (ISS), Live Science reports.
As the media outlet points out, this type of lighting is difficult to spot from the ground because it’s discharged from above thunderclouds.
The rare lightning, known as “blue jet,” was detected by the ISS on 26 February 2019 as it shot out of a thunderstorm near the Pacific island of Nauru.
Detailing their findings in a paper published on 20 January in the Nature journal, the science team also mentioned several “intense flashes of blue light” that preceded the blue jet lightning, with four of these flashes identified as “emissions of light and very low-frequency perturbations due to electromagnetic pulse sources,” or ELVES for short.
“This paper is an impressive highlight of the many new phenomena ASIM is observing above thunderstorms,” said Astrid Orr, physical sciences coordinator for human and robotic spaceflight with the ESA.
A statement by the space agency also mentions that investigators suspect such phenomena “could even influence the concentration of greenhouse gasses in Earth’s atmosphere, underscoring once more how important it is to find out exactly what’s going on above our heads.”
