De er meget almindelige p\u00e5 Jorden, hvor tordenskyer ofte udl\u00f8ser kraftige elektriske udladninger i vores atmosf\u00e6re. Der er stadig meget, vi ikke forst\u00e5r ved lyn, men en oplevelse, som en ESA-astronaut har haft, har givet forskerne meget at t\u00e6nke over.<\/p>\n<\/div>\n<p>Astronauten var Andreas Mogensen, der var ombord p\u00e5 Den Internationale Rumstation i 2015. Da han befandt sig i kredsl\u00f8b og fl\u00f8j over Indien, rettede han et h\u00f8jteknologisk kamera mod en gigantisk tordenstorm, som han kunne se nedenunder. Andreas fik \u00f8je p\u00e5 en bl\u00e5 str\u00e5le, der sk\u00f8d op i de \u00f8verste lag af Jordens atmosf\u00e6re.

Forskerne begyndte at forst\u00e5, hvilke typer skyer der kan udl\u00f8se de bl\u00e5 jetstr\u00e5ler, og hvordan de \u00e6ndrer luftens kemiske sammens\u00e6tning omkring sig.
