3. Blue Lightning in Outer Space
Get ready to wow yourself! Although we usually link lightning with the atmosphere of Earth, blue lightning has been seen in the most unlikely location: deep space. Astronauts on the International Space Station (ISS) made this startling discovery when they saw blue jets of lightning flying upward from thunderclouds towards the edge of space. Far higher than typical lightning, these blue jets—a type of blue lightning—can soar elevations of up to 50 kilometres above the surface of Earth. Rising above thunderstorms, the phenomena known as “transient luminous events” consists in sprites, elves, and blue jets, all kinds of upper-atmospheric lightning. This realisation has transformed our knowledge of atmospheric electricity and its interaction with the space environment. The identification of blue lightning in space has opened fresh directions of investigation in atmospheric science, space weather, and even the hunt of livable exoplanets. These space-bound electrical discharges could influence the ionosphere of the Earth and thereby perhaps damage world communication networks, according to scientists today. Apart from improving our understanding of Earth’s atmosphere, the research of blue lightning in space offers insights on the atmospheres of other worlds where such events could take place.
4. Blue Lightning and Climate Change
Among experts, the link between blue lightning and climate change is one of increasing interest. Recent research have indicated that patterns of global climate could affect the frequency of blue lightning events. Changes in atmospheric circumstances as our planet heats could perhaps modify the probability of blue lightning development. Rising global temperatures could, some scientists speculate, cause more frequent and severe thunderstorms, which would therefore cause a greater occurrence of blue lightning incidents. Still under research, though, is the precise nature of this link. Developed to forecast how variations in temperature, humidity, and atmospheric composition could influence the incidence of several kinds of lightning, including the elusive blue variant, are climate models. Understanding the instantaneous effects of climate change on weather patterns is simply one benefit of this study; another is evaluating possible long-term consequences on atmospheric electricity and its significance in the Earth’s climate system. Examining blue lightning in the framework of climate change could shed important light on the intricate connections among several layers of our atmosphere and their responses to changes in the surroundings.
