18 juni 2012: World renowned astrophotographer and ESO Photo Ambassador, Serge Brunier, has returned to ESO’s observatory sites in Chile and this time he is sharing his experiences on a live blog hosted by the Skypix Science et Vie website. The blog posts are available in English and in French. You can also follow Serge’s adventures on Twitter by searching for the hashtag #ESOlive. Serge was at the La Silla Observatory, located on the outskirts of the Atacama Desert, 600 km north of Santiago de Chile at an altitude of 2400 metres. On this site ESO operates some of the most productive 4-metre-class telescopes in the world. After La Silla, Serge is heading further north in Chile to the Paranal Observatory, home of the Very Large Telescope and nearby Cerro Armazones, where ESO will be building the European Extremely Large Telescope — the world’s biggest eye on the sky.

11 juni 2012: On 11 June 2012 at 18:00, a ceremony took place at ESO’s Headquarters in Garching bei München, Germany, to mark the laying of the foundation stone of a major new extension to the ESO building. A time capsule containing a scroll listing the names of the ESO Council delegates, the latest issue of The ESO Messenger and a copy of a local newspaper for the day was also sealed and placed in the foundations during the ceremony. The Headquarters extension will feature an office building, a technical building and a covered bridge that will connect the new buildings to the original Headquarters. The buildings will make extensive use of natural light sources and there will be two inner courtyards. This striking and innovative design is in keeping with the current building and retains the same curved shapes. Further details about the building are available here: eso1215. The new office building, ...

11 juni 2012: with Dr. Anita Winter (Max Planck Institute for Extraterrestrial Physics, MPE) Cosmic X-rays give us important information about high-energy events happening in the Universe. But to observe this type of energetic radiation astronomers need to work with satellites equipped with powerful telescopes, whose mirrors consist of numerous concentric shells. Traditional methods for manufacturing these shells led to heavy mirrors, which is a major restriction as they need to be launched into space. The Max Planck Institute for Extraterrestrial Physics (MPE) has developed a new, special technique using glass panes, which results in significantly lighter mirrors and thus enables the construction of telescopes with larger collecting surfaces. On 12 June, Dr. Anita Winter (MPE) will discuss the opportunities and challenges that these new technologies are bringing. Please note that the Café & Kosmos events take place in German. What: Technology of the future for new X-ray telescopesWhen: Wednesday, 12 June 2012, ...

5 juni 2012: De nieuwe ALMA-telescoop - the Atacama Large Millimeter/submillimeter Array – krijgt al voordat hij klaar is een ‘upgrade’. Daarmee kunnen astronomen de vroegste sterrenstelsels onderzoeken en zoeken naar water in andere planeetstelsels. De Raad van Toezicht van ALMA heeft het ontwerp en de bouw goedgekeurd van een extra set ontvangers van topkwaliteit, die de telescoop toegang geeft tot een deel van het spectrum dat nu niet met ALMA kan worden bestudeerd. ALMA is ’s werelds grootste sterrenkundige project. De nieuwe, krachtige faciliteit op de Chajnantor-hoogvlakte in Chili geeft astronomen inzicht in de manier waarop het heelal en zijn sterrenstelsels zijn geëvolueerd sinds de oerknal, en in de manier waarop sterren en planeten in ons eigen melkwegstelsels zijn gevormd. Hoewel pas de helft van de 66 antennes op de hoogvlakte in Noord-Chili staan (zie ann12035), is ALMA al operationeel en worden nu met een gedeeltelijke opstelling wetenschappelijke waarnemingen gedaan (zie eso1137). ...

5 juni 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. ESOcast 44 — entitled Changing Views — is the fourth special episode of this series. Since its birth, fifty years ago, ESO has helped to improve our knowledge of the Universe by means of successive generations of powerful optical ground-based telescopes. But there are other ways to collect the light from distant objects. In this episode, we discover how ESO has helped astronomers to explore the Universe at longer wavelengths, such as the infrared and radio regimes. The human eye is only sensitive to a small part of the electromagnetic spectrum. We are not able to see light with wavelengths longer than red, or shorter than violet. But by observing the sky at longer wavelengths, ...

4 juni 2012: On Wednesday 6 June, the Presidents of four Latin-American countries will gather at ESO’s Paranal Observatory in Chile’s Atacama Desert, where the Fourth Summit of the Pacific Alliance is due to take place. Paranal is the home of ESO’s Very Large Telescope (VLT), the world's most advanced visible-light astronomical observatory. Presidents Sebastián Piñera of Chile, Ollanta Humala of Peru, Juan Manuel Santos of Colombia, and Felipe Calderón of Mexico will hold a meeting to ratify the Framework Agreement of the Pacific Alliance, to promote regional integration and higher growth, development and competitiveness between the Member Countries of the Alliance, with the aim to move progressively towards the goal of achieving free movement of goods, services, capital and persons. Representatives from Costa Rica and Panama were invited as observers, and officials from Canada, Japan and Australia were also invited as guests. The President of the ESO Council, Xavier Barcons, the Director ...

31 mei 2012: The 12th issue of the free peer-reviewed journal for science communicators, Communicating Astronomy with the Public (CAPjournal), is now available for download. One of the highlights of the issue discusses the different tools science communication specialists use to gauge how well they reach their target audiences — in other words, how they know what actually works. Another article is focused on the Mars Crowdsourcing Experiment, a crowdsourcing project that investigates whether the players of a computer game can support scientific research by tagging surface features on Mars. Also in this issue, there is an article on the project Multiverso, a cultural initiative in which an astronomer and a rock musician team up, combining their passions to create awareness about astronomy. Since late 2009, the project has reached tens of thousands people in Spain through various events such as the release of an album and a set of concert-talks.

31 mei 2012: On 11 June 2012 at 18:00, a ceremony will be held at ESO’s Headquarters in Garching bei München, Germany, to mark the laying of the foundation stone of a major new extension to the ESO building. The innovatively styled new office building, designed by architects Auer+Weber+Assoziierte, will allow ESO to bring all its Garching staff, some of whom are currently in temporary offices or other buildings on the Garching campus, back together on a single site. The building will be the cradle of the technological innovations needed for ESO’s ambitious projects such as the European Extremely Large Telescope (further details are available here: eso1215). The event will coincide with the meeting in Garching of ESO’s governing body, the ESO Council. Representatives of the ESO Member States will be present, as well as the ESO Director General, and representatives of the local authorities and the town of Garching. Members of the ...

30 mei 2012: The new technology of laser frequency combs (eso0826) [1] has now been tested with the HARPS [2] planet-finder on the ESO 3.6-metre telescope at the La Silla Observatory in Chile. Frequency combs provide reference light sources of extraordinary stability and have the potential to allow HARPS and similar instruments to make much more precise measurements than is currently possible [3]. This novel technique is expected to become a revolutionary tool for the astronomical community and help astronomers to find Earth-like planets in the habitable zones around nearby stars. The results are being presented in a paper to appear in the 31 May 2012 edition of the journal Nature.A team of scientists from ESO, the Max Planck Institute of Quantum Optics (MPQ, Garching, Germany) and the Instituto de Astrofisica de Canarias (IAC, Tenerife, Spain) — led by Tobias Wilken, a researcher at MPQ — has used a laser frequency comb to ...

30 mei 2012: The European Astronomical Society [1] has announced that the 2012 Tycho Brahe Prize has been awarded to Professor Reinhard Genzel, in recognition of his outstanding contributions to European near-infrared instrumentation and for groundbreaking work in galactic and extragalactic astronomy. German astronomer Reinhard Genzel — director of the Max Planck Institute for Extraterrestrial Physics — and his team were responsible for building SINFONI, a near-infrared integral-field spectrograph attached to the ESO Very Large Telescope. Since its first light in 2005, SINFONI has become a key instrument for the study of the structure and dynamics of distant galaxies and, in particular, of the dynamics of our home galaxy, the Milky Way. His team has been involved in an unprecedented 20-year-long study of the movement of stars around the galactic centre, which is based on observations made with ESO’s New Technology Telescope at La Silla Observatory as well as ESO’s Very Large Telescope ...

22 mei 2012: ESO has taken a further step towards the construction of the European Extremely Large Telescope (E-ELT) by awarding the preliminary design study contract for the adaptive fourth mirror (M4) of the E-ELT to the AdOptica consortium made up of ADS International (Italy) and Microgate (Italy) [1]. This mirror will be a major milestone in adaptive optics technology, becoming the largest adaptive mirror ever made for a telescope. It will be crucial for exploiting the E-ELT’s unprecedented potential, allowing astronomers to achieve major scientific breakthroughs during the next decades. The M4 mirror is part of the E-ELT’s adaptive optics system, which will be responsible for correcting the blurring effects produced both by turbulence in the atmosphere, and the effects of wind on the telescope structure. When installed this remarkable deformable mirror will allow the E-ELT to reach the theoretical maximum resolution possible in its observations [2].The M4 flat mirror will be ...

15 mei 2012: On the Chajnantor plateau in northern Chile, construction of the Atacama Large Millimeter/submillimeter Array (ALMA), the most complex ground-based astronomy observatory in the world, continues apace. On 12 May 2012, another ALMA antenna was carried up to Chajnantor, bringing the total on the plateau to 33. This marks a half-way point for ALMA, as the telescope will have a total of 66 antennas when completed in 2013. The giant antennas, fifty-four of them with 12-metre-diameter dishes, and twelve with 7-metre-diameter dishes, use sensitive receivers to detect millimetre- and submillimetre-wavelength light from the cosmos. The first of the antennas made the trip up to the 5000-metre-altitude Array Operations Site in September 2009 (see eso0935). Now, as ALMA approaches completion, antennas are arriving at an increasing rate. The state-of-the-art ALMA antennas, which weigh about 100 tonnes each, need a custom-constructed transporter vehicle to move them between the Operations Support Facility and the ...

11 mei 2012: with Dr. Martin Gorbahn (Excellence Cluster Universe)While the Standard Model of particle physics explains many details of the building blocks of matter and their interactions, many questions still remain unanswered. Several on-going experiments, including CERN’s Large Hadron Collider, will help to clarify things. With these new tools, we can now study the forces of nature down to a scale of 10-19 metres, which is about one ten thousandth of the diameter of a proton! During the next Café & Kosmos, Dr. Martin Gorbahn will discuss what physicists expect to see at that scale. Please note that the Café & Kosmos events take place in German. What: Digging down into the quantum worldWhen: Tuesday, 15 May 2012, 19:00 until approximately 20:30Where: Vereinsheim, Occamstr. 8, 80802 München, near Münchener FreiheitAdmission is free.

10 mei 2012: Voorafgaand aan ESO’s vijftigste verjaardag in oktober 2012, publiceren we acht speciale ESOcasts. Elke ESOcast is een hoofdstuk uit de film Europe to the Stars – ESO’s First 50 Years of Exploring the Southern Sky. De derde bijzondere aflevering van de serie - ESOcast 43 - presenteert het vlaggenschip van alle ESO-faciliteiten: de Very Large Telescope (VLT). In deze aflevering ontdekken we de state-of-the-art technologie die achter deze telescoop schuilgaat en astronomen een ongeëvenaarde kijk op het universum gunt. Om de scherpste afbeeldingen van de hemel te vergaren, moet de VLT rekening houden met twee belangrijke effecten die een vertekend beeld van de hemellichamen veroorzaken. Het eerste is een vervorming van de spiegel, omdat deze zo groot is. Dit probleem wordt gecorrigeerd met een computergestuurd controlesysteem - actieve optica - dat ervoor zorgt dat de spiegels hun gewenste vormen onder alle omstandigheden behouden. Het tweede effect wordt veroorzaakt door de ...

27 april 2012: Event organisers are invited to join an international series of coordinated public events on 5 October 2012 marking the 50th anniversary of the founding of the European Southern Observatory. The events will celebrate Europe’s quest to explore the southern sky, with unique and exciting activities. ESO invites venues such as public observatories, planetariums, science centres, museums, art galleries, and other public spaces, as well as organisers working with these venues, to apply to host one of these events. The centrepiece of the coordinated events will be a live connection to ESO’s Paranal Observatory, in Chile, home of the world’s most advanced visible light astronomical observatory — the Very Large Telescope (VLT). A never-before-seen stunning astronomical image from ESO will also be unveiled. In addition to the live streaming and never-before-seen image, ESO representatives will visit venues to talk about ESO’s state-of-the-art observatories, and the latest scientific and technological results. Organisers ...

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 (www.opticks.info) is the one who first put forward the idea to Moonbounce images and continues to apply her professional experience in this ...

26 april 2012: De Europese Zuidelijke Sterrenwacht (ESO) nodigt publieksssterrenwachten, planetaria, wetenschapscentra, musea, galerieën en andere openbare ruimten - maar ook organisatoren die samenwerken met deze locaties -, uit om deel te nemen aan de tentoonstellingscampagne 2012/2013, die in het teken staat van het onderzoek van de zuidelijke sterrenhemel. 'Spectaculair Heelal - de kosmos gezien door de ogen van de Europese Zuidelijke Sterrenwacht' markeert de vijftigste verjaardag van ESO. Er zijn subsidies voor financiële ondersteuning beschikbaar. De tentoonstelling is gericht op het grote publiek. Bezoekers krijgen 50 verbluffende beelden te zien van hemellichamen zoals sterrenstelsels, nevels en sterrenhopen, die zijn vastgelegd door de ESO-observatoria - de thuisbasis van de meest geavanceerde telescopen ter wereld - maar ook prachtige beelden van de sterrenwachten zelf, die zich op een aantal zeer bijzondere locaties op aarde bevinden. Extra tentoonstelllingspanelen geven informatie over ESO en tonen de hoogtepunten van de eerste 50 jaar van deze sterrenwachten. De ...

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 ...

4 april 2012: with Dr Frank Simon (Max Planck Institute for Physics) The study of the early Universe requires the most modern particle accelerators in order to explore the behaviour of the smallest building blocks of the cosmos. During the next Café & Kosmos, we will take a look at the evolution of the earliest stages of the Universe, and also on the future projects that will influence our understanding of physics. On 10 April 2012, Dr Frank Simon (Max Planck Institute for Physics) will discuss the moments just after the Big Bang, when the Universe was filled with elementary particles. To understand this period of the cosmos better, new and even more powerful instruments will be required. Future particle accelerators, including global projects like the International Linear Collider (ILC) and the Compact Linear Collider (CLiC), will serve as huge particle microscopes to look deep into the history of the Universe. Please note ...
