Polar Mesopheric Clouds | International Space Station


ESA Astronaut Alexander Gerst: "High, cold and icy. These polar mesospheric clouds are still a mystery to science, but the Space Storm Hunter outside Columbus is investigating. At around 80 km altitude, they often reflect the sun while Earth underneath is already dark, appearing noctilucent."

Polaren Höhenwolken
"Hoch, kalt, eisig. Diese polaren Höhenwolken über Nordeuropa sind immer noch ein Rätsel, doch unser ASIM-Experiment untersucht es bereits. In 80 km Höhe reflektieren sie oft noch Sonnenlicht, wenn die Erde darunter bereits dunkel ist, und erscheinen nachtleuchtend."
