Arstechnica | Data from the International Space Station confirms: Lightning is insaneThu 12 Dec 2019, 13:01Lightning is such a common phenomenon that people often overlook just how powerful it is (provided it doesn't hit you, obviously). But over the past decade, research has gradually revealed just how extreme lightning is. This everyday phenomenon is powerful enough to produce antimatter and transform atoms, leaving a radioactive cloud in its wake. Understanding how all of this happens, however, is a real challenge, given just how quickly multiple high-energy events take place. |

ISS Sees Thunderstorm Beaming Electromagnetic Pulse Into Area, Producing Gamma Rays and ‘Elves´'Thu 12 Dec 2019, 12:56At 8:01 p.m. on October 10, 2018, a bolt of lightning flashed within a storm cloud simply east of the Indonesian island of Sulawesi. The Worldwide Area Station was passing overhead on the time, and a collection of devices noticed because the bolt produced a flash of gamma radiation—and, concurrently, emitted a glowing ring of ultraviolet and visual gentle within the topmost layer of the environment. |

High above the storm clouds, lightning powers gamma-ray flashes and ultraviolet ‘elves‘Thu 12 Dec 2019, 12:52Using instruments onboard the International Space Station, researchers have observed millisecond pulses of gamma-rays produced by thunderstorms, clarifying the process by which these flashes are made, and discovering that they can produce an ultraviolet emission known as an "Elve." |

DTU-forskere afdækker Klodens ekstreme energiudladningerWed 11 Dec 2019, 14:58Nu er der nyt fra Danmarks store rummission ASIM, som blev sendt i rummet i fjor, hvor DTU Space er videnskabelig leder. Forskerne kan nu forklare mere om de voldsomme fænomener, der opstår i forbindelse med tordenvejr over skyerne. Den nye viden er netop publiceret i det videnskabelige tidsskrift Science. |

Space-station cameras reveal how thunderstorms trigger gamma-ray burstsWed 17 Jul 2019, 15:54Nature article: Mysterious electrical flashes above storm clouds have long puzzled scientists. “This is a game changer,” says Nikolai Østgaard, a space physicist at the University of Bergen in Norway. He described the findings in a pair of talks at the International Union of Geodesy and Geophysics meeting in Montreal, Canada, on 9 and 12 July. Picture: NASA/JSC |

How do thunderstorms affect the Earth’s climate?Thu 11 Apr 2019, 15:40The Atmosphere-Space Interactions Monitor (ASIM) was launched last April in an effort to study severe thunderstorms. Just a year later, the observation facility is already providing scientists with a better understanding of the role that thunderstorms play in the Earth’s atmosphere and climate and how lightning is created.
