observatories spring to life. Astronomers and technicians take their positions, and telescopes are pointed skywards. This image shows the pristine skies over ESO's Paranal Observatory in the Chilean Atacama Desert, far away from city lights. Here, ESO photo ambassador Gabriel Brammer has captured the serene beauty of the Milky Way from the platform of the Very Large Telescope. The four massive blocks in the bottom of the image are the four VLT Unit Telescopes, each of them housing incredibly precise 8.2-metre mirrors. Scattered around are the VLT's Auxiliary Telescopes, easily identifiable due to their round, white domes. The bright spot to the left is the Moon, shining as brightly as if it were the Sun, and to the right, the shadow of the photographer can be seen, waving to the viewer with outstretched arms. The entire night sky is visible due to Brammer's use of a ...</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/web/20210413025107/https://www.eso.org/public/images/potw1351a/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210413025107im_/https://cdn.eso.org/images/thumb350x/potw1351a.jpg"> </div> <div class="news-description"> <div class="news-id">potw1351 — Picture of the Week</div> <div class="news-title">Season's Greetings from the European Southern Observatory!</div> <div class="news-teaser"><strong>23 December 2013</strong>: Season's Greetings on behalf of everyone at the European Southern Observatory!

Tafreshi, one of ESO’s Photo Ambassadors, at ESO’s Paranal Observatory. It shows three of the four Auxiliary Telescopes (ATs) of the Very Large Telescope Interferometer (VLTI). Above them, the long bright stripes are star trails, each one marking the apparent path of a single star across the dark night sky, due to the rotation of the Earth. This technique also enhances the natural colours of the stars, which gives an indication of their temperature, ranging from about 1000 degrees Celsius for the reddest stars to a few tens of thousands of degrees Celsius for the hottest, which appear blue. The sky in this remote and high location in Chile is extremely clear and there is no light pollution, offering us this amazing light show.</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/web/20210413025107/https://www.eso.org/public/images/potw1349a/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210413025107im_/https://cdn.eso.org/images/thumb350x/potw1349a.jpg"> </div> <div class="news-description"> <div class="news-id">potw1349 — Picture of the Week</div> <div class="news-title">Nova Centauri 2013 seen from La Silla</div> <div class="news-teaser"><strong>9 December 2013</strong>: Alpha and Beta Centauri, two of the brightest stars in the southern sky, had a new companion in late 2013 — the naked eye Nova Centauri 2013. This photo was taken by ESO Photo Ambassador Yuri Beletsky at ESO's La Silla Observatory in the Chilean Atacama Desert in the morning hours of Monday 9 December 2013. The nova was discovered by John Seach from Australia on 2 December 2013 as it approached naked eye brightness. Nova Centaurus 2013 is the brightest nova to have occurred so far this millennium. This particular event is known as a classical nova, and is not to be confused with a supernova. Classical novae occur in binary star systems when hydrogen gas from the orbiting stellar partner is accreted onto the surface of the main star, causing a runaway thermonuclear event resulting in the brightening of the main star.

To the right, competing for attention as it arcs above the horizon, a beautiful, almost triangular band of diffuse light lies along the ecliptic, which is the apparent path of the Sun in the sky as seen from the Earth. This glow originates in the scattering of sunlight by dust located between the planets that are spread through the plane of the Solar System.

Suddenly, Klaas heard a loud snort behind him and the sound of massive feet chasing him.

Many professional astronomers are also keen photographers — and who could blame them? ESO sites in the Atacama Desert are among the best places on Earth for observing the stars, and for the same reason, are amazing places for photographing the night sky. Håkon took these photos while on a week-long observing run at the MPG/ESO 2.2 -telescope. During this time, the telescope was occasionally handed over to a different observing team, giving Håkon the opportunity to admire the starry night — as well as to capture it for the rest of us to see.
