15. huhtikuuta 2014: ESO’s Paranal–Armazones site in Chile has been shortlisted as one of two potential sites in the southern hemisphere for the international Cherenkov Telescope Array (CTA) — a large array for ground-based gamma-ray astronomy. This is an important step towards the realisation of the project and if the site is selected, this will open up a new frontier for ESO. On 10 April 2014 Government representatives from the 12 of the countries [1] involved in the Cherenkov Telescope Array (CTA) project met in Munich and decided to start negotiations with the two sites — Aar in Namibia and ESO's Paranal–Armazones site in Chile — keeping Leoncito in Argentina as a third option. The CTA project is an initiative to build the next generation of ground-based, very high energy gamma-ray instruments. The CTA project aims to use detection of high-energy gamma-rays to provide a deeper insight into the high-energy Universe. The representatives ...

2. huhtikuuta 2014: A magnitude 8.2 earthquake struck northwest Chile at 20:46 local time (01:46 CEST) on Tuesday 1 April 2014. The epicentre was about 95 kilometres north-west of the city of Iquique. The earthquake has caused significant casualties and damage in coastal regions. Large parts of the Pacific coast were evacuated in response to tsunami warnings. ESO expresses its deepest condolences to the families of the victims, and its sympathy and support for all those affected by the earthquake. The epicentre was about 500 kilometres from both the ALMA/APEX and Paranal sites. No casualties among ESO staff have been reported, and no damage to any ESO facilities, but this is affecting staff with families and friends in the north of Chile. Some of the staff at Paranal come from the most affected regions in Iquique and Arica. To our knowledge all staff currently on site have in the meantime been able to ...

Next, they will drive to ALMA, the Atacama Large Millimeter/submillimeter Array ...

26. maaliskuuta 2014: This episode of the ESOcast presents the recent discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings. Telescopes at seven locations in South America, including the 1.54-metre Danish and TRAPPIST telescopes at ESO’s La Silla Observatory in Chile were used to make this surprise discovery in the outer Solar System. This unique finding has sparked much interest and debate since it is the smallest object by far to have rings and only the fifth body in the Solar System — after the much larger planets Jupiter, Saturn, Uranus and Neptune — to have this feature. Astronomers think that this sort of ring is likely to be formed from debris left over after a collision. The story of this unique and unexpected discovery is told in ESOcast 64: First Ring System Around an Asteroid. More episodes of the ESOcast are also available. Find out how to ...

25. maaliskuuta 2014: An international team of astronomers, led by Felipe Braga-Ribas (Observatório Nacional/MCTI, Rio de Janeiro, Brazil), has used telescopes at seven locations in South America, including the 1.54-metre Danish and TRAPPIST telescopes at ESO’s La Silla Observatory in Chile, to make a surprise discovery in the outer Solar System. This unexpected result raises several unanswered questions and is expected to provoke much debate. A press conference will be held in Brazil to present the new results and allow opportunities for questions. Note that all information regarding these findings is under strict embargo until 19:00 CET (15:00 BRT) on Wednesday 26 March 2014. When: The conference will be held on 26 March 2014 at 14:30 local time (BRT) and will take place in Portuguese with a summary in English.

24. maaliskuuta 2014: A new 22-watt laser has now been accepted from the system supplier TOPTICA and its partner MPB following nearly five years of sustained collaboration and effort (see ann1045, ann1048, ann11039, ann12012 and ESOcast 34). This laser system will form part of the Adaptive Optics Facility at ESO’s Very Large Telescope (VLT) [1]. This laser, and four further similar units (including one spare) that will be delivered later, constitute key elements of the new facility and this acceptance marks a major step forward for the project. Five years ago the options for obtaining high power, reliable lasers in a compact format suitable for the requirements of the Adaptive Optics Facility were very limited. But now new technology and dedicated research and development have changed the landscape. After three months of acceptance testing at ESO, the project team was very happy with the performance of the new hardware, which holds great promise ...

14. maaliskuuta 2014: The civil works for the European Extremely Large Telescope (E-ELT) have begun. The Chilean company, ICAFAL Ingeniería y Construcción S.A. (ICAFAL), has started construction of a road to the summit of Cerro Armazones. Currently there is no paved road from the public highway to the top of the mountain. The road construction work is expected to take 16 months and will provide access to the summit for the future construction work on the giant telescope. Once complete, the road will be 11 metres wide in total, with an asphalt paved driveway of 7 metres width. ICAFAL will also be responsible for the levelling of the top of the mountain later this year and additional civil works. The peak must be modified to create a platform to construct the telescope and other supporting facilities. The start of telescope operations is planned for early in the next decade, when the E-ELT will ...

14. maaliskuuta 2014: A survey of the number of peer-reviewed scientific papers published in 2013 using data from ESO’s telescopes and instruments has shown that ESO remains the world’s most productive ground-based observatory. Astronomers used observational data from ESO facilities to produce 840 refereed papers last year. The number of papers published from ESO data in 2013 has even remained slightly higher than the number of papers using data from the NASA/ESA Hubble Space Telescope. Nearly 70% of all papers credited to ESO in 2013 used data acquired using the Very Large Telescope (VLT) or VLT Interferometer facilities. The most productive VLT instruments in terms of papers remain FORS2 and UVES. X-shooter also showed a steep increase in the number of publications and has produced a total of almost 170 papers from 2010 to 2013. Other facilities at the La Silla Paranal Observatory — including the survey telescope VISTA at Paranal, as well ...

12. maaliskuuta 2014: The ESO Director General, Tim de Zeeuw, together with ESO Council President Xavier Barcons, ESO Representative in Chile Fernando Comerón, and Director of Operations Andreas Kaufer met Michelle Bachelet, the incoming President of Chile, on 10 March 2014, the day before her inauguration. The delegation passed on their congratulations, and looked forward to a fruitful and productive collaboration between ESO and its host nation. This meeting took place at the Academia Diplomática de Chile (Diplomatic Academy of Chile) where Michelle Bachelet also held meetings with several high level organisations and delegations from all over the world who had been invited to the ceremonies marking the handover of power in Chile. Later in the afternoon, Fernando Comerón and Tim de Zeeuw attended an official reception with the outgoing President of Chile, Sebastián Piñera, at the Palacio de La Moneda in Santiago, where they had the opportunity of personally thanking him for ...

4. maaliskuuta 2014: Award-winning French actress Juliette Binoche and Irish actor Gabriel Byrne visited ESO’s Paranal Observatory in northern Chile on 22 February 2014. Juliette Binoche then travelled on to visit ALMA on 24 February. Famed for their performances in many successful films, Juliette Binoche and Gabriel Byrne expressed an interest in visiting the most prominent observatories during their free time in northern Chile. They are currently shooting an upcoming film named The 33 — based on the dramatic true story of the miners who were successfully rescued after many weeks trapped underground following an accident at the San José mine in 2010. The actress and actor were hosted at Paranal by ESO's Director of Administration Patrick Geeraert and ESO's Representative in Chile Fernando Comerón. Arriving in time to watch the sunset at Cerro Paranal on 22 February, they saw the opening of the VLT domes as they prepared for the night ahead. ...

19. helmikuuta 2014: In our latest episode of the ESOcast, we delve into the history of telescope mirrors and their evolution over time. Enormous telescope mirrors allow astronomers to peer much deeper into the night sky than the tiny light-collecting area of the human eye permits. In this episode, the reason for the ever-growing size of telescopes is explored as the story behind these flexible giants is told. The challenges of building larger yet lighter mirrors have paved the way for innovative thinking and have consequently led to telescope designs such as ESO’s New Technology Telescope (NTT) and the future European Extremely Large Telescope (E-ELT). To find out how and why such designs revolutionised telescope mirror design, explore the past, present and future of telescope mirror design in ESOcast 63: Flexible Giants — The Evolution of Telescope Mirrors. More Information The ESOcast is a video podcast series dedicated to bringing you the latest ...

18. helmikuuta 2014: SPHERE — the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument — is a powerful new facility for finding and studying exoplanets. The instrument has recently successfully completed testing in France, passed preliminary acceptance by ESO, and has now been shipped to Chile. It will then be installed on ESO’s Very Large Telescope (VLT) and first light is foreseen for May 2014. SPHERE was built by a consortium of astronomers and engineers in many ESO states in conjunction with industry [1]. The consortium is led by the Institut de Planétologie et d'Astrophysique de Grenoble, France. SPHERE’s main goal is to find and characterise giant exoplanets orbiting nearby stars by direct imaging [2]. This is an extremely challenging task as such planets are both very close to their parent stars in the sky and also very much fainter. In a normal image, even in the best conditions, the light from the star totally swamps ...

13. helmikuuta 2014: As part of the Austrian contribution when it joined ESO, a specialist team from institutes in Linz [1] has developed adaptive optics algorithms and software methods that are much faster than those using more traditional approaches. These methods are used for the correction of images that are degraded due to atmospheric turbulence — and are in particular intended for use with the future 39-metre European Extremely Large Telescope (E-ELT). The challenging goal was to invent a new and different approach to this problem that is as effective as current techniques while, at the same time, greatly reducing the computing load on the computer that performs the calculations. This four-year project has just completed a very successful final review. The new adaptive optics algorithms are very fast and provide excellent quality results. This leads to enormous savings in computing power required to handle adaptive optics data from the E-ELT. But probably ...
