The magic of a pristine sky 🤩The Milky Way arches over our Very Large Telescope, set under a colourful sky. This so-called airglow is extremely faint and only noticeable in the darkest regions, such as the Atacama Desert in #Chile. So, preserving pristine skies not only enables cutting-edge research, but it also allows photographers to capture the magic of a perfectly dark night.https://www.eso.org/public/images/potw2543a/📷 J.
