Colourful clouds, plumes and dots in the sky over Norway last Friday. Not extra terrestrials – all NASA’s doing apparently. To wit:

The colours were actually created by the NASA-funded Auroral Zone Upwelling Rocket Experiment (AZURE) which dispersed gas tracers to probe winds in Earth’s upper atmosphereAZURE’s tracers originated from two short-lived sounding rockets launched from the Andøya Space Center in Norway. The harmless gases, trimethylaluminum and a barium/strontium mixture, were released into the ionosphere at altitudes of 115 and 250 km. The vapor trails were observed dispersing from several ground stations. Mapping how AZURE’s vapors dispersed should increase humanity’s understanding of how the solar wind transfers energy to the Earth and powers auroras.
