href="/web/20210120133009/https://www.eso.org/public/outreach/partnerships/photo-ambassadors.html">ESO's Photo Ambassadors</a>, who are constantly experimenting with new techniques to obtain even more striking views of the unique, arid landscape and state-of-the-art facilities.</p><p>On this occasion, Gianluca Lombardi has combined many long-exposure images to get this stunning result — the Very Large Telescope (VLT) and its Auxiliary Telescopes, their motion appearing as blurred flickers beneath a stream of stars, while the apparent motion of the stars across the sky has left smeared trails that are captured on camera as the Earth rotates.</p><p>The VLT is ESO's flagship facility. It is of the most productive telescopes in the world, and the most advanced optical instrument ever made.</p></p><strong>Credit:</strong><div class="credit"><p>ESO/G.
