    RE: mastodon.social/@esoastronomy/

    The video, illuminated by the low-lying sun, shows not only the unusual #snow ❄️ cover but also the dense clouds, which are extremely rare in one of the driest places on Earth. The observatories are built there precisely because the dry conditions offer the best possible prerequisites for #astronomical observations heise.de/en/news/Extremely-Lar

    #Satellites in #Earth #orbit play a major role in everyday life on Earth and make the global #connectivity via our media possible in the first place. However, the increasing number of satellites in #lowEarthorbit (#LEO) can also #brighten the #nightsky in places and interfere with #astronomical #observations. Degen et al. (2026) recommend #retroreflective #coatings on satellites to #redirect #sunlight in order to reduce brightness.
