The sky is pitch-black over the big observatories in Chile, you think? Often it is ... But sometimes natural 'light pollution' strikes (wonder how much that compromises observations).https://twitter.com/AstroGuigeek/status/1223945803322052608 …

Winter night-sky over @ESO's #LaSilla observatory in the outskirts of the Atacama Desert. Two phenomena are visible here: Zodiacal light (blue tinted light) and Red Airglow. A dark sky is not always dark but transparent; displaying the true natural lights of the sky.
