Observatory in the Chilean Atacama Desert appears to curve around the mountain and collide with the downward slope of the Milky Way in this Picture of the Week. Small yellow bulbs light up the road at regular intervals; it is prohibited to use headlights on these roads between dusk and dawn, as even dim lights can interfere significantly with telescope observations. The site enjoys some of the darkest night skies on Earth. The darkness, high altitude, and resulting dry air at La Silla make it an exceptional location for astronomy. In the foreground of this image, the Danish 1.54-metre telescope is performing its nightly observations. Its instruments have allowed astronomers to achieve several “firsts”. In 2005, for example, astronomers observed the afterglows of short gamma-ray bursts and showed that the bursts are likely caused by the dramatic collision of two neutron stars, while in ...</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/20210128195518/https://www.eso.org/public/images/potw2103a/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210128195518im_/https://cdn.eso.org/images/thumb350x/potw2103a.jpg"> </div> <div class="news-description"> <div class="news-id">potw2103 — Picture of the Week</div> <div class="news-title">A Telescopic Quartet</div> <div class="news-teaser"><strong>18 January 2021</strong>: Far from civilisation, deep in the barren, mountainous terrain of Chile’s Atacama Desert, stand four pillars of modern astronomy: the enormous and angular enclosures of the Unit Telescopes (UTs) of ESO’s Very Large Telescope. The Sun’s diffuse orange glow peeking over the horizon is no match for the light display filling the sky above. Containing hundreds of billions of stars, the great bow of the Milky Way stretches across the panorama, dipping down to touch the horizon. The mottled look of our home galaxy is due to huge clouds of interstellar dust obscuring more distant starlight. Bright stars, celestial objects, and other phenomena in our cosmic neighbourhood hang like lanterns in the Chilean sky, backlit by ethereal red and green airglow. Alone, each UT can make magnificent observations of the Universe from their home at ESO’s Paranal Observatory — but the four telescopes can also work together and observe the ...</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/20210128195518/https://www.eso.org/public/images/potw2102a/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210128195518im_/https://cdn.eso.org/images/thumb350x/potw2102a.jpg"> </div> <div class="news-description"> <div class="news-id">potw2102 — Picture of the Week</div> <div class="news-title">Rose of star formation around distant supermassive black hole</div> <div class="news-teaser"><strong>11 January 2021</strong>: Captured with the MUSE instrument on ESO’s Very Large Telescope (VLT), this image of the distant spiral galaxy NGC 1097 shows a textbook example of a star-bursting nuclear ring. Located 45 million light-years away from Earth, in the constellation of Fornax, this ring lies at the very centre of its galaxy. It spans only 5,000 light years across, being dwarfed by the full size of its host galaxy, which extends some tens of thousands of light-years beyond its centre. The darker lanes seen in this MUSE image show dust, gas and debris from the galaxy (or possibly from a satellite galaxy), which are being funnelled into the supermassive black hole at its centre. This process heats up the surrounding matter forming an accretion disc around the black hole and launching huge amounts of energy into the surrounding area. Nearby dust is heated up and star formation accelerates in the area ...</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/20210128195518/https://www.eso.org/public/images/potw2101a/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210128195518im_/https://cdn.eso.org/images/thumb350x/potw2101a.jpg"> </div> <div class="news-description"> <div class="news-id">potw2101 — Picture of the Week</div> <div class="news-title">A behemoth seen from above</div> <div class="news-teaser"><strong>4 January 2021</strong>: ESO’s Very Large Telescope (VLT) is one of the most advanced optical and infrared observatories in the world. This magnificent astronomical detective comprises an array of four individual Unit Telescopes — the large cylindrical domes visible in this image — each hosting a main mirror measuring 8.2 metres in diameter. It also includes four movable 1.8-metre diameter Auxiliary Telescopes — the, comparatively, small white, round domes seen to the left of the Unit Telescopes. The VLT has contributed to groundbreaking observations and discoveries, including snapping the first image of an extrasolar planet and observing the visible counterpart to a gravitational wave source. In this picture, the telescopes are resting, their domed eyelids firmly closed as they slumber at ESO’s Paranal Observatory in Chile — but at night they will awaken to observe the Universe and make more fantastic discoveries.</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> </div> <div class="row statusbar"><div class="col-md-3"> Showing 1 to 4 of 4 </div><div class="col-md-6"><div class="text-center"><ul class="pagination"><li class="active"><a href="/web/20210128195518/https://www.eso.org/public/images/potw/archive/year/2021/list/1/">1</a></li></ul></div></div><div class="col-md-3 prev-next"></div></div><div class="row"><div class="col-md-12"></div></div> <div class="copyright"> <a href="/web/20210128195518/https://www.eso.org/public/outreach/copyright/">Usage of ESO Images, Videos, Web texts and Music</a><br/> </div> </div> </div> </div> </div> </div>  <div class="row footernote"> <div class="col-xs-12 col-md-3"> <a href="https://web.archive.org/web/20210128195518/mailto:information@eso.org">Send us your comments!</a> </div> <div class="col-xs-12 col-md-3"> <a href="/web/20210128195518/https://www.eso.org/public/outreach/newsletters/esonews/">Subscribe to receive news from ESO in your language</a> </div> <div class="col-xs-12 col-md-3"> <a href="https://web.archive.org/web/20210128195518/https://www.cdn77.com/">Accelerated by CDN77</a> </div> <div class="col-xs-12 col-md-3"> <a href="/web/20210128195518/https://www.eso.org/public/about-eso/privacy/">Terms & Conditions</a> </div> </div> <link href="/web/20210128195518cs_/https://www.eso.org/public/archives/djp/css/extras.166b25c68b97.css" rel="stylesheet" type="text/css"/> <script type="text/javascript">var MEDIA_URL = "/public/archives/"</script> <script type="text/javascript" src="/web/20210128195518js_/https://www.eso.org/public/archives/djp/js/main.097c0244ddc7.js" charset="utf-8"></script> </div>  <div id="social-share" class="hidden-print"> <div class="link facebook" data-toggle="tooltip" data-placement="right" title="Share on Facebook"> <a href="https://web.archive.org/web/20210128195518/https://www.facebook.com/sharer/sharer.php?u=https://www.eso.org/public/images/potw/archive/year/2021/" target="_blank"><i class="fa fa-facebook" aria-hidden="true"></i></a> </div> <div class="link twitter" data-toggle="tooltip" data-placement="right" title="Share on Twitter"> <a href="https://web.archive.org/web/20210128195518/http://twitter.com/intent/tweet?url=https://www.eso.org/public/images/potw/archive/year/2021/&text=&via=ESO" target="_blank"><i class="fa fa-twitter" aria-hidden="true"></i></a> </div> <div class="link pinterest" data-toggle="tooltip" data-placement="right" title="Share on Pinterest"> <a href="https://web.archive.org/web/20210128195518/http://pinterest.com/pin/create/button/?url=https://www.eso.org/public/images/potw/archive/year/2021/&media=&description=" target="_blank"><i class="fa fa-pinterest" aria-hidden="true"></i></a> </div> <div class="link print" data-toggle="tooltip" data-placement="right" title="Print"> <a href="javascript:window.print()" target="_blank"><i class="fa fa-print" aria-hidden="true"></i></a> </div> <div class="link email" data-toggle="tooltip" data-placement="right" title="Share by email"> <a href="https://web.archive.org/web/20210128195518/mailto:%20?subject=ESO — Picture of the Week 2021&body=https://www.eso.org/public/images/potw/archive/year/2021/" target="_blank"><i class="fa fa-envelope-o" aria-hidden="true"></i></a> </div> </div> <script> $('[data-toggle="tooltip"]').tooltip(); </script> <input type="hidden" name="csrfmiddlewaretoken" value="wypQNJtPjhJlKm6urQ9h1MAZYPCvY2VJ0Yh9AQ8y0LvCRYmpW5LGd7RnHsQbp9iy"/> </body> </html>
