ESO Travels to the Moon and Back During its 50th Anniversary Year
27 April 2012: On 21 April 2012, amateur radio operator Jan van Muijlwijk pointed the Dwingeloo Radio Telescope in the Netherlands at the Moon. Radio waves carrying a digital version of the ESO’s 50th anniversary logo were then transmitted into outer space from Howard Ling’s amateur radio station in England. After the signals bounced off Earth’s natural satellite they were picked up by Jan, less than three seconds later, after a round trip of about 800 000 km. The result can be seen in this image which literally traveled to the Moon and back. Patrick Barthelow, who works with Echoes of Apollo and is a keen promoter of Moonbounce [1] outreach and STEM [2] education activities was the initiator of this project to mark ESO’s 50th anniversary. Artist Daniela de Paulis ( is the one who first put forward the idea to Moonbounce images and continues to apply her professional experience in this ...

ESOcast 42: Looking Up
19 April 2012: Leading up to ESO’s 50th anniversary in October 2012, we are releasing eight special ESOcasts, each a chapter from the movie Europe to the Stars — ESO’s First 50 Years of Exploring the Southern Sky. “Looking Up” is the second special episode of this series and ESOcast 42 overall. In it we look at how, over the past fifty years, ESO has helped to unravel some of the mysteries of the Universe in which we live. Astronomers were in need of more powerful tools to observe the sky and ESO provided them. A new generation of revolutionary ground-based telescopes has offered astronomers a front-row seat to study the wonders of the Universe. From the relative proximity of the planets in our Solar System to very distant galaxies, some of which are seen soon after the Universe was born, almost fourteen billion years ago, ESO’s telescopes and advanced instrumentation are allowing ...

ESO Remains World’s Most Productive Ground-based Observatory By Far
28 March 2012: Astronomers used observational data from ESO’s telescopes and instruments to write a total of 783 refereed papers during 2011. This is an all-time high in ESO’s history. ESO remains the most productive ground-based observatory by far. Over the past few years the number of papers using observations from ESO has been almost identical to the number from observations made with the NASA/ESA Hubble Space Telescope, with both rising rapidly after a slight dip in 2009. The VLT/VLTI alone provided data for 551 papers in 2011, an increase of about 8% since 2010. The total number of papers using VLT/VLTI data is now well above 4000. Papers that use data taken from the ESO archives have been accounting for a steady fraction of 12% during recent years, with a strong increase in 2011. Remarkably, even if the contribution from ESO’s flagship VLT/VLTI telescopes is excluded from the total, the remaining telescopes ...

ESOcast 41: Going South
21 March 2012: Leading up to ESO’s 50th anniversary in October 2012, we are releasing eight special ESOcasts, each a chapter from the movie Europe to the Stars — ESO’s First 50 Years of Exploring the Southern Sky. This first special episode — entitled “Going South” — describes the birth of ESO, and in particular why astronomers from European countries decided to explore the southern sky by placing an astronomical observatory in Chile. Until fifty years ago, almost all major telescopes were located north of the equator. However, astronomers soon realised the importance of the southern sky. For instance, the centre of the Milky Way, our home galaxy, can hardly be seen from the northern hemisphere but in the south it passes high overhead. Other important objects are the Magellanic Clouds — two small companion galaxies to the Milky Way — which cannot be observed from Europe, but which are very conspicuous south ...

ESO Images in a Universal Context
9 March 2012: The European Southern Observatory has launched an initiative to attach extra information about context (metadata) to the images in its huge collection. The Astronomy Visualization Metadata standard that is now implemented has been developed in collaboration with many other major observatories, including partners from NASA, ESA, the California Academy of Sciences and the University of Arizona. It is now easier than ever to learn more about the fantastic imagery of the Universe, including the archives of ESO. The Astronomy Visualization Metadata (AVM) standard was created to make access to astronomical images easier by collecting extra information in a standard way [1]. This extra information — known as metadata — includes details similar to those included with every digital snapshot picture coming from cameras today — who took the picture, when was it taken, where in the sky was the camera pointed and so on. It is, however, specifically designed for ...

Café & Kosmos 14 March 2012
9 March 2012: with Dr. Henk Spruit (Max-Planck-Institut für Astrophysik) Global warming and the greenhouse effect of carbon dioxide affect us all. The Sun brings us the warmth that we need to live. But could part of global warming be caused by changes in the Sun, and not by our greenhouse gases? In other words, are we the main culprits after all? In the news, we hear regularly about destructive tropical storms, extreme cold, or unusually warm winters. Are these caused by the global warming? Insurance companies have gathered a lot of statistics. Dr. Henk Spruit (Max-Planck-Institute für Astrophysik) will debate these critical issues with Café & Kosmos guests on 14 March. He will also discuss recent changes in the Sun, and explain how we understand our star and what is happening inside it. Please note that the Café & Kosmos events take place in German.

BMW and Paranal
6 March 2012: The iconic Bavarian car-maker BMW chose ESO’s Paranal Observatory, home of the Very Large Telescope (VLT), for the global campaign featuring the brand’s latest high-end model, the 6 Series Gran Coupé, which will have its world debut at the Geneva International Motor Show on 6 March 2012. The exclusive car can be seen parked in front of some of the VLT’s Unit Telescopes and Auxiliary Telescopes. People who know the real observatory will no doubt notice that a new building was added. The revised site, with its prominent metallic and earth colours and BMW’s new coupé could seem straight out of a James Bond movie. In fact, the Paranal Observatory’s award-winning Residencia is just that. Another unusual element of the image is the presence of clouds. While clouds are common in most places on Earth, Paranal enjoys 330 clear days per year, so to get a balanced composition clouds had to ...

Super-thin Mirror for Sharper Star Images
2 March 2012: A remarkable thin-shell mirror for ESO’s Very Large Telescope has been delivered by the French company SAGEM. It is 1120 millimetres across but just 2 millimetres thick, making this mirror much thinner than most glass windows. This mirror has to be thin enough to act almost like a flexible film. When installed in the telescope the shape of its reflective surface will be constantly changed by tiny amounts to correct for the blurring effects of the Earth’s atmosphere and create much sharper images. The shell mirror is a sheet of ceramic material that has been polished to a very accurate shape. The manufacturing process starts with a block of Zerodur ceramic, provided by Schott Glass (Germany) that is more than 70 millimetres thick. Most of this material is ground away to create the final thin shell. The challenge is to apply very little pressure and low levels of stress to ...

Multiple E-ELT Mirror Segments Tested Together for the First Time
24 February 2012: The next pieces of the jigsaw for the European Extremely Large Telescope (E-ELT) — the world’s biggest eye on the sky — are coming together. At ESO’s Garching facility in Germany, a full-size mock-up of a small section of the E-ELT primary mirror and its support structures provides a first test of multiple segments of the E-ELT’s main mirror. Four of the 1.45-metre segments — the final mirror will have 798 — are being put through their paces to see how these hexagonal mirrors and their complex support units behave in real conditions, and whether they match the exacting requirements needed for the telescope. The mirror segments are made from different types of material from different manufacturers and are not yet coated to make them reflective. The current tests focus on the mechanical support systems, whose advanced sensors and actuators are used to keep the separate segments in the right ...

VLT's New Laser Launchers Arrive at ESO
22 February 2012: Four special telescopes to fire laser beams high into the atmosphere to create artificial stars have been delivered to ESO. These are vital components of the Four Laser Guide Star Facility (4LGSF) for ESO’s Very Large Telescope (VLT) that were developed by the Netherlands Organisation for Applied Scientific Research (TNO). The 4LGSF is part of a next-generation adaptive optics system, the Adaptive Optics Facility (AOF), that will make the VLT’s 4th Unit Telescope Yepun a fully adaptive telescope in 2013. Composed of four powerful 20-watt lasers, the 4LGSF will help the VLT correct the image distortion caused by turbulence in the air. Telescopes usually collect light coming from the sky and focus it into an instrument. However, the new components send light in the opposite direction. These “launchers”, are used to project the lasers into the sky to create brilliant points of light. The laser beams excite a layer of ...
