The video #Megaconstellation threat to astronomy (and more) is linked in the sidebar of the ESO release but deserves a separate shout-out. Also learned that the actual paper has just been formally published in https://www.aanda.org/articles/aa/pdf/forth/aa60006-26.pdf - and see https://gizmodo.com/eso-study-finds-that-no-more-than-100000-satellites-should-orbit-earth-2000780091 for an article.
