15 juni 2011: The ESO Annual Report 2010 is now available. It presents the many activities of the European Southern Observatory throughout the last year, covering topics including: ESO’s research highlights, with the latest results from the fields of exoplanet detection, the study of massive stars, and the history of star formation. An overview of the activities of ESO’s telescopes. A description of the status of the astronomical instruments at the La Silla and Paranal observatories, detailing new installations and upgrades. The progress of the exciting ALMA and E-ELT projects.

15 juni 2011: With a decision by ESO Council to endorse a revised baseline design for the E-ELT, ESO is one step closer to starting construction of the European Extremely Large Telescope (E-ELT) on 3060-metre-high Cerro Armazones near ESO’s Very Large Telescope site in Chile. After the successful E-ELT Design Review in September 2010 and with Brazil joining ESO (eso1050), the E-ELT project is now not only technically ready to enter the construction phase, but is also backed by a solid funding scenario.Between the end of 2010 and the summer 2011, the E-ELT project extended the detailed design phase in order to consider the recommendations of the E-ELT Design Review. The main goals were the reduction of risk by optimising the cost and constraining the schedule to make sure that ESO can further expand its leading role in astronomy by constructing the world’s first extremely large telescope.In June 2011, the ESO Council endorsed ...

10 juni 2011: The latest issue of Science in School, the European journal for science teachers, is now available online and in print. As with previous issues, number 19 is packed with inspiring science articles, classroom games, and hands-on activities. The science news and educational projects featured in issue 19 cover topics that range from biology and chemistry to the environment, particle physics, and astronomy. An exciting article, about a planet of extragalactic origin that is now within our own galaxy, tells more of the story behind a recent ESO news item. The planet, detected by a European team of astronomers using the MPG/ESO 2.2-metre telescope, orbits a star that originally belonged to a dwarf galaxy that was captured by the Milky Way. Other articles cover topics including space habitats, DNA fingerprinting, the chemistry of amber, and why the famously bright yellows of van Gogh’s paintings are darkening over time.

8 juni 2011: This ESOcast introduces the VLT Survey Telescope (VST), the latest addition to ESO’s Paranal Observatory. This new telescope has just made its first release of impressive images of the southern sky. The VST is a state-of-the-art 2.6-metre telescope, with the huge 268-megapixel camera OmegaCAM at its heart. It is designed to map the sky both quickly and with very fine image quality. It is a visible-light telescope that perfectly complements ESO’s VISTA infrared survey telescope. Strikingly detailed images of the Omega Nebula and the globular cluster Omega Centauri demonstrate the VST’s power.

6 juni 2011: On the nights of 15–17 May 2011, astronomers successfully applied a new observing technique on ESO’s Very Large Telescope Interferometer (VLTI). The new procedure is called “blind observation mode” and will allow interferometric observations to be made of targets significantly fainter than before. It has already produced detailed observations of the spectrum of a quasar, 10 times fainter than the best currently known results. The result was obtained by combining the light from three of the VLT’s 8.2-metre Unit Telescopes in the AMBER [1] beam combiner. The ground-breaking technique, developed by a team of astronomers led by Romain Petrov from the Laboratoire Fizeau (Université de Nice, Observatoire de la Côte d’Azur and CNRS, France), allows them to observe targets that would ordinarily be far too faint to be detected by an interferometer. They do this by first observing a bright star near the faint target, which allows them to calibrate ...

3 juni 2011: On 3 June 2011 in Prague, an agreement was signed committing the Czech Republic to provide its full share of the additional financial contribution required for construction of the European Extremely Large Telescope (E-ELT). The agreement was signed by the Director of the Department of International Cooperation in Research and Development of the Ministry of Education, Youth and Sports of the Czech Republic, Dr Jan Marek — authorised by the Minister of Education, Youth and Sports, Josef Dobeš — and the ESO Director General, Prof. Tim de Zeeuw. The contribution will be made in two equal instalments, in 2012 and 2014, subject to approval of E-ELT construction by the ESO Council, which is currently planned to occur in December of this year. This agreement will help ESO keep its leadership in the field of ground-based astronomy. “This agreement is an important step on the road to building the E-ELT, which ...

3 juni 2011: As people see no connection between their everyday experience and the concepts of quantum mechanics, they usually perceive the subject as strange and complicated. Quantum mechanics is the theme of the next Café & Kosmos discussion on Tuesday, 7 June 2011: Dr Stefan Kluth, from the Max-Planck Institute for Physics, will show that quantum mechanics has much more impact on our daily life than it appears. He will also discuss how important the principles of quantum mechanics are for our understanding of astronomical observations. The Café & Kosmos series of discussions is organised jointly by ESO, the Excellence Cluster Universe and the Max-Planck Institutes for Physics, Astrophysics and Extraterrestrial Physics. The discussions take place on the second Tuesday of each month at the Vereinsheim, in Munich (please note the change of day and venue, as of May 2011). After a brief introduction the scientists take questions from the audience and ...

20 mei 2011: A special event has been held in London on 19 May 2011, at which officials from the European Southern Observatory (ESO) briefed UK companies on what they need to do to get involved in the European Extremely Large Telescope (E-ELT) project. Around 60 UK businesses attended the event. As with companies from the other ESO Member States, British companies are being urged to bid for a share of a billion Euros that will be available in contracts for the E-ELT, which will be the biggest optical and infrared telescope in the world. The E-ELT will be a 42 metre telescope that will be a revolutionary tool in astronomy. Among other goals, it will have the task of tracking down Earth-like planets, capable of harbouring life, that orbit distant stars. Building the E-ELT will take more than just its state-of-the-art optics. The telescope is a major civil engineering project and will ...

12 mei 2011: The Cerro Paranal site was chosen to host ESO’s flagship telescope, the VLT, because it is one of the driest and most remote places on Earth. This may make for excellent observing conditions, but the desert is a hostile environment. Water and vegetation are virtually non-existent, not to mention the lack of modern amenities such as power.How is it possible to run such advanced technology in this barren environment? And how does the site manage to support the staff and visitors at the Paranal Residencia?This episode of the ESOcast takes us behind the scenes of the Paranal Observatory and shows us how they overcome the immense challenges of life in the Atacama Desert.Watch more ESOcast episodes here.

11 mei 2011: Public information officers, educators, science communicators, journalists, bloggers and professional and amateur astronomers are invited to attend or give talks at the 2011 Communicating Astronomy with the Public (CAP2011) conference, to take place between 10 and 14 October 2011 at the Xiyuan Hotel in Beijing, China. With online platforms boosting popularity and traffic, there is a whole new world building up in the social media and elsewhere online, a world where individuals become opinion leaders by owning and sharing information. For this new audience, traditional ways of communicating science are no longer enough. If science wants to keep up, it needs to learn how to communicate through the social media and online as well as continuing to come up with innovative and unconventional approaches in the offline world. CAP2011 will focus directly on how to bring science to the people of today and tomorrow. The major themes of the conference ...

3 mei 2011: Black holes are probably the most exotic objects in astronomy: they are the most compact objects the Universe has to offer, they bend space and time and they hurl jets of matter out into the vastness of space at almost the speed of light. It is also interesting to consider the celestial objects associated with black holes: X-ray binaries, gamma-ray bursts, quasars and blazars. It is no wonder that they haunt the imaginations of science fiction authors. Black holes also play an important role in astrophysics; their influence on the formation and evolution of stars and galaxies has only become clear in recent decades. But can the existence of these extraordinary objects be explained? This and other fascinating questions will be addressed during the next Café & Kosmos on Tuesday, 10 May 2011, at 19:00, by the astrophysicist Andreas Müller (Excellence Cluster Universe, & TUM), who has been studying black ...

28 april 2011: Three unique and remarkably perfect toric mirrors, which are a vital component for SPHERE, a new instrument at the VLT, have been successfully completed and tested. SPHERE is one of the second generation of VLT instruments and it will search for giant Jupiter-sized exoplanets orbiting nearby stars, using direct imaging. The mirrors were manufactured for SPHERE at the Laboratoire d’Astrophysique de Marseille (LAM) in France. The mirrors are called toric because their surfaces have slightly different curvatures in different directions — like the surface of a large torus, or doughnut. Directly detecting exoplanets is one of the most exciting areas of modern astronomy, but it is also undoubtedly one of the most challenging. Sometimes likened to trying to spot a firefly against the overwhelming light of the Moon; the enormous contrast in brightness between the host star and the orbiting planets means that an extraordinarily sensitive and precise instrument is ...

27 april 2011: By studying some of the oldest stars in our galaxy, an international team of astronomers led by Cristina Chiappini [1] has used data from ESO’s Very Large Telescope to show that the first massive stars in the Universe were probably very fast rotators, which they have dubbed spinstars. Their findings will be published in an article in Nature on 28 April 2011. Massive stars live fast and die young, so the first generation of massive stars in the Universe is already dead. However, their chemical imprint, left behind like an incriminating fingerprint, can still be found today in the oldest stars in the Milky Way. These fossil records provide valuable clues about the mysterious first stellar generation to enrich the pristine early Universe. Soon after the Big Bang, the Universe was made almost entirely of hydrogen and helium. It was only enriched with other elements around 300 million years later ...

21 april 2011: The first European antenna for the Atacama Large Millimeter/submillimeter Array (ALMA) project has just been handed over to the Joint ALMA Observatory. The antenna, which has a dish 12 metres in diameter and weighs about 95 tonnes, was moved from the Site Erection Facility where it was assembled and tested, to the observatory’s Operations Support Facility (OSF). Although this was only a short trip between two adjacent sites at an altitude of 2900 metres in the foothills of the Chilean Andes, the move is nevertheless very important. “This move was just a short trip for this antenna, but it marks a big step for the project. This milestone is the result of many years of hard work by the engineering teams of the AEM Consortium [1] and by the ESO staff involved in following up the design, and the construction and testing activities in Chile,” says Stefano Stanghellini, the ALMA ...

20 april 2011: On 17 March 2011 light collected by all four of the 8-metre Unit Telescopes of ESO’s Very Large Telescope was successfully combined for the first time using PIONIER [1], a new generation instrument in the VLT Interferometer. To have all four Unit Telescopes (UTs) finally working together as a single telescope is a major step in the development of the VLT — the original design always anticipated that the four 8-metre telescopes would be able to work either independently or together as part of the giant VLT Interferometer (VLTI). Coincidentally, the new observations took place on the 10th anniversary of the first successful combination of two beams within the VLTI. Among the main science goals for the four UTs, working together with PIONIER, are to try to reveal the signatures of planets in the making, to explore the natures and fates of stars by providing images of their surfaces and ...

13 april 2011: Life has just become much easier for parents and educators dealing with enthusiastic children curious about astronomy! ESO has teamed up with the educational project Universe Awareness (UNAWE) [1] to produce Space Scoop — versions of its latest Science and Photo Releases that are written specifically for children aged between 7 and 11 years old. In a world where children are sometimes more technically savvy than grown-ups, Space Scoop is meant to feed their curiosity about the Universe, by allowing them to access ESO releases in their own language. “Astronomy is an incredibly dynamic subject; ESO astronomers continue to uncover new clues about how the Universe works, and we want to share the excitement of this journey of discovery with a younger audience,” says Lars Lindberg Christensen, Head of ESO’s education and Public Outreach Department. Parents can also use the service to read about the latest discoveries in astronomy and ...

5 april 2011: The European Southern Observatory (ESO) operates some of the most powerful ground-based telescopes in the world. Building and maintaining such grand instruments requires external help, and ESO has forged many strong working relationships with industry to secure the necessary technical expertise. Since 2005, ESO has awarded contracts worldwide totalling more than 600 million euros, the vast majority of which have been placed with companies in the ESO Member States and Chile. You can find out more about ESO’s relationship with industry, as well as the opportunities that are available for the ESO Extremely Large Telescope (E-ELT), for which construction is due to begin by the end of this year, in the new printed flyer, ESO and Industry.
