Annonces 2017

22 mai 2017: ESO has awarded a multi-million euro contract to the international company Teledyne e2v to design and produce a set of Large Visible Sensor Modules for use on the Extremely Large Telescope (ELT). Scheduled to see first light in 2024, the ELT is at the forefront of telescope technology. In order for the telescope to capture the Universe in exquisite detail, the ELT will use highly sophisticated adaptive optics systems which will enable it to adjust for changes in the atmosphere above it. These systems will require sensors of the highest quality. Each sensor, with a size of 800 x 800 pixels, will employ Teledyne e2v’s renowned CMOS technology. Their extreme sensitivity and fast response will permit the ELT’s adaptive optics systems to make tiny adjustments around 700 times a second to compensate for variations in Earth’s atmosphere. This will ensure that the resulting astronomical images — of exoplanets, distant galaxies ...

12 mai 2017: An extension of the agreement between the partners of the Atacama Pathfinder Experiment (APEX) has been signed, ensuring that this very productive collaboration will continue until the end of 2022. The 12-metre APEX telescope saw first light in 2005 and has provided astronomers with detailed views of the coldest objects and processes in the Universe. APEX is a collaborative effort between the Max-Planck-Institute for Radio Astronomy (MPIfR) in Bonn, Germany, ESO and the Onsala Space Observatory (OSO) in Onsala, Sweden, and the agreement was signed by ESO’s Director General, Tim de Zeeuw, Karl Menten, Director at the Max-Planck-Institut für Radioastronomie and John Conway, Director of the Onsala Space Observatory. The ceremony took place at Chalmers University of Technology in Gothenburg, Sweden. Under the APEX extension agreement, the telescope will be upgraded to significantly improve the overall observing efficiency, and the suite of instruments will be upgraded to a new generation. ...

11 mai 2017: CNRS Images, in partnership with ESO, has produced a documentary about MUSE, the Multi Unit Spectroscopic Explorer. Directed by Christophe Gombert and Claude Delhaye, MUSE, The Cosmic Time Machine takes a detailed look at one of the latest — and in fact, the biggest — second-generation instruments installed on Yepun (UT4), the fourth Unit Telescope of ESO’s Very Large Telescope at the Paranal Observatory in Chile. The 35-minute documentary explores the inspiration and the story behind MUSE, why it was needed, and how it came into life over a nine year development phase. It highlights the international European cooperation necessary to realise the project, as well as the participation of many of the hundreds of researchers, technicians and engineers involved. The innovative technology of MUSE and the front-line science performed with it are also discussed, braided with a gripping storyline of the delicate installation process leading up to the moment ...

10 mai 2017: Astronomers from around the world have submitted a record 1712 proposals to observe with the Atacama Large Millimeter/submillimeter Array (ALMA) during its next observing cycle (Cycle 5). Cycle 5 runs between October 2017 and September 2018. The deadline for submitting a proposal was 15:00 UT on 20 April 2017. A preliminary filtering process showed that 48 proposals were duplications, reducing the number of unique ones to 1665. All complete proposals will be evaluated and ranked at a meeting in Antwerp, Belgium, to be held between 18 and 23 June 2017. During Cycle 5, it is expected that 56 ALMA antennas will be available at any one time for observations (46 12-metre antennas and 10 7-metre antennas). All ALMA receiver bands from 3 to 10 will also be available. The maximum baseline — distance between the antennas — will be 16 kilometres, giving ALMA, at its highest operating frequencies, an angular ...

9 mai 2017: The Australian Minister for Industry, Innovation and Science, Senator the Hon Arthur Sinodinos, has announced his Government’s intention to open negotiations with ESO on a strategic partnership that would see Australia participate in all activities related to the La Silla Paranal Observatory.

3 mars 2017: A survey of peer-reviewed scientific papers published in 2016 and 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 an all-time high of 936 refereed papers last year. There were 565 papers credited to ESO in 2016 that used data acquired with either the Very Large Telescope (VLT) or the VLT Interferometer facilities on Cerro Paranal. The three most productive VLT instruments in terms of papers are UVES, FORS2 and VIMOS, which featured in 123, 109 and 75 papers, respectively. The MUSE and SPHERE instruments also saw large increases from the previous year. Data from the VISTA and VST survey telescopes on Cerro Paranal led to 93 and 18 papers, respectively. Facilities located at La Silla provided data for almost 200 papers in total. HARPS remains La Silla’s most productive instrument, with ...

22 février 2017: A total of seven Earth-like, potentially habitable worlds have been discovered orbiting a nearby star known as TRAPPIST-1. Just 40 light-years away, the star’s diminutive size and dim light output mean it is known as an ultracool dwarf. ESOcast 96 explores this important discovery, from how the astronomers made the incredibly intricate measurements required to find and study the planets — including observations with ESO’s Very Large Telescope — to each world’s potential to support life as we know it. Excitingly, three of the planets in the system orbit in the habitable zone around TRAPPIST-1, and could harbour oceans of water on their surfaces. Dwarf stars like TRAPPIST-1 are very common in our galaxy, making rich planetary systems like this some of the best targets in humanity’s search for life elsewhere in the Universe. This ESOcast takes you on a journey through one such system, which contains both the largest ...
