NASA Reveals Spectacular Photos of Rare Space Station Event

Originally Published 15 days ago — by Indian Defence Review

NASA and international researchers are using the International Space Station to capture unprecedented images and data on upper-atmospheric electrical discharges like red sprites, blue jets, and ELVES, which occur above thunderstorms and can impact communication and climate. Instruments like ESA's ASIM, the Light-1 CubeSat, and ultra-high-speed cameras are advancing understanding of these phenomena, their effects on the ionosphere, and their potential risks to aviation and space operations.

"Discovery: Unraveling the Enigma of Mesospheric Ghosts"

Originally Published 2 years ago — by Big Think

In 2019, nature documentarian Hank Schyma captured a mysterious green afterglow, dubbed the "green ghost," following red sprite events during intense thunderstorms. This rare mesospheric emission, requiring specific atmospheric conditions and asteroid dust, was finally documented by astrophysicists in a study published in "Nature Communications" in 2023. The green ghost appears in the footprint of a red sprite and has been observed by amateur storm chasers more frequently than researchers, with the U.S. Great Plains being notorious for their large quantities of sprites.
