5 April 2016: ESO Photo Ambassador Petr Horálek is in Chile at the moment, as a member of ESO’s Fulldome Expedition, amassing photographic images to use in planetarium shows. The material will be used in ESO’s Supernova Planetarium & Visitor Centre, currently under construction at ESO’s Headquarters in Garching, Germany. As a warm-up he captured this astonishingly rich image of the skies above ESO’s Paranal Observatory, home of the Very Large Telescope facility. Thanks to the magic of photography, Petr himself also appears in this image, gazing in wonder at the display above him. The Milky Way arches above the illuminated dome of the astronomers’ hotel — La Residencia, as it is called — which has been specially designed so as not to produce any light pollution that would interfere with the operation of the telescopes. Other splendours of the southern sky, including the Magellanic Clouds just above the dome of the Residencia, ...

1 April 2016: The ESO Supernova Planetarium & Visitor Centre, in collaboration with the Haus der Astronomie, Heidelberg, is organising a one day workshop on Kepler’s Laws for secondary school teachers, on Friday 1 July 2016. German speaking teachers from any of the ESO Member States are welcome to attend. The aim of the workshop is to show how important Kepler’s Laws are to modern astronomy. In particular, Kepler’s Third Law allows scientists to estimate the masses of supermassive black holes and of planets orbiting other stars, while deviations from Kepler’s laws exhibited by galaxy rotation curves led to the discovery of dark matter. Through a combination of short introductory talks and interactive workshops, participating teachers will be provided with educational materials they can use directly in the classroom. The ESO Supernova Planetarium & Visitor Centre is currently under construction and as such, the training session will be held at ESO Headquarters in ...

29 March 2016: An agreement has been signed between ESO and the Centre National de la Recherche Scientifique [1], acting on behalf of the Institut de Planétologie et d’Astrophysique de Grenoble, to build a new adaptive optics system for the auxiliary telescopes that form part of ESO’s Very Large Telescope Interferometer (VLTI) array [2] at the Paranal Observatory in Chile. The new system, called the New Adaptive Optics Module for Interferometry (NAOMI) will make a big improvement to the imaging capability of the VLTI. The VLTI is already a remarkable astronomical facility that has made significant contributions to the study of various objects, like young pre-main sequence stars and their protoplanetary discs, post-main sequence mass-losing stars, and active galactic nuclei. A NAOMI module will be installed on each of ESO’s 1.8-metre Auxiliary Telescopes (AT), bringing a more advanced adaptive optics system to the ATs that will allow them, and the VLTI array, to ...

29 March 2016: A survey of peer-reviewed scientific papers published in 2015 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 860 refereed papers last year. There were 550 papers credited to ESO in 2015 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 X-shooter, which featured in 144, 91 and 78 papers, respectively. Data from the VISTA survey telescope on Cerro Paranal led to 73 papers. Facilities located at La Silla provided data for more than 200 papers in total. HARPS remains La Silla’s most productive instrument, with 81 papers to its name, an increase of ten over last year. The number of papers based on European observing time ...

23 March 2016: Scientists and engineers have begun mapping out the detailed specifications of two new instruments that will be part of the instrument suite on ESO’s forthcoming European Extremely Large Telescope (E-ELT). MOS (the Multi-Object Spectrograph) and HIRES (the High Resolution Spectrograph) will be world-leading workhorse instruments on what will be the world’s largest telescope. The contract to begin design studies for MOS was signed on 18 March 2016 by ESO and the CNRS-INSU, the leading institution in the MOSAIC consortium [1]. The instrument will combine high spectral and spatial resolution and will carry out wide-field surveys in the visible and infrared parts of the spectrum. It will allow astronomers to probe some of the deepest mysteries of the Universe: when did the first galaxies form and how did they aggregate into large structures like the Milky Way; how are ordinary matter and dark matter distributed throughout the Universe; and how do ...

21 March 2016: On 26 April 2016 an event will be held at the Paranal Observatory in Chile to mark the first light of a new laser unit on ESO’s Very Large Telescope. Members of the press are invited to attend the event (at their own cost), and those who wish to do so are asked complete this RSVP form. The event will include an optional visit to Cerro Armazones, the future home of the European Extremely Large Telescope. Known as the Four Laser Guide Stars Facility (4LGSF), the new system will use four lasers to create artificial guide stars anywhere in the sky, permitting the adaptive optics systems to compensate for the blurring caused by the Earth’s atmosphere. ESO and industry partners have together built the brightest laser guide stars used on any telescope. They will extend the VLT’s ability to produce some of the sharpest images of celestial objects available from ...

The winners were selected from a total of 322 entrants from 55 countries who responded to the 2015 Open Call. Quadrature will take up a residency at one of ESO’s observatories in Chile, followed by a month at the Ars Electronica Futurelab in Linz, Austria where they will develop and create new work inspired by the visit to ESO. ESO congratulates Quadrature on their receipt of this award and looks forward to an inspiring and ...

14 March 2016: In 2014, Dutch astronomer Frans Snik designed a model of ESO’s European Extremely Large Telescope (E-ELT) using LEGO® components. Following on from the success of that design (more than ten models have been built by enthusiastic individuals worldwide since it was published), Snik has now dedicated some of his spare time to designing a LEGO® model of one of the Unit Telescopes that make up ESO’s Very Large Telescope (VLT). For almost 20 years now, the VLT has been amazing astronomers with its extraordinary capabilities. One of the largest telescope facilities in the world, the VLT consists of four independent telescopes that can be operated together to make a very powerful facility. Now ESO is building its big brother, the ELT, that will extend our reach even further into the heavens. You may not be able to build your own full-size versions of these telescopes, but the models are a ...

The journal addresses science teaching across Europe and across disciplines, highlighting the best in teaching and cutting-edge research. Numerous articles, as well as ...

4 March 2016: ESO’s observatories in Chile are located at such incredibly dark sites that normally the only thing illuminating them on a moonless night is the faint light from the billions of stars in the Milky Way. But even the darkest sky is not completely dark. This ESOcast describes the magnificent natural light phenomenon known as Zodiacal light, that sometimes casts a ghostly glow in the skies above ESO’s telescopes. It is the glow of sunlight as it is reflected towards us by dust in the plane of the Solar System, dust that is created by collisions between asteroids and the evaporation of comets. Yet another of the natural wonders that astronomers at ESO’s observatories are lucky enough to witness for themselves; we hope that you too will enjoy the Zodiacal light show! You can subscribe to the ESOcasts in iTunes, receive future episodes on YouTube or follow us on Vimeo. Many ...

15 February 2016: ESO is organising its first social media gathering at its sites in Chile to coincide with the 2016 transit of Mercury. #MeetESO will be a meeting dedicated exclusively to keen social media users from ESON countries who enjoy sharing information about astronomy. Selected participants should travel to Chile between 7 and 12 May 2016. #MeetESO will take participants to the Very Large Telescope (VLT) — the world's most advanced visible-light astronomical observatory, and the Atacama Large Millimeter/submillimeter Array (ALMA), the largest ground-based astronomical project in existence. Participants will travel to the most arid desert in the world and climb to 5000 metres above sea level. They will be accommodated at ESO’s Residencia, the astronomers’ hotel and the building apparently blown up in one of the James Bond movies. The programme also includes: night-time observations from one of the best spots on Earth, day-time observations of the transit of Mercury, a ...

10 February 2016: A celebration was held at the APEX [1] base station in Sequitor, San Pedro de Atacama, to mark ten years of astronomical research with the APEX telescope, which resides on Chile’s Chajnantor Plateau, 5100 metres above sea level. From there, the telescope observes the sky in submillimetre wavelengths, giving astronomers access to the coldest regions of the Universe, which cannot be seen in visible light. As it looks forward to further discoveries at the forefront of observational astronomy, the APEX 12-metre telescope has already made significant contributions across a variety of astronomical fields, including the discovery of new interstellar molecules and deep imaging of the submillimetre sky, leading to new insights into star formation in the Milky Way and distant starburst galaxies in the early Universe. The Sequitor base station was chosen for the celebration, as it is at the more comfortable altitude of 2500 metres above sea level. But ...

4 February 2016: At an extraordinary meeting in Garching bei München, Germany on 3 February 2016, ESO’s Finance Committee authorised ESO to enter into final discussions with the winning bidder of the tender process for the design, manufacture, transport, construction, on-site assembly and verification of the Dome and Main Structure of the European Extremely Large Telescope (E-ELT). The discussion between ESO and the ACe Consortium, consisting of Astaldi, Cimolai and the nominated sub-contractor EIE Group will start soon, with the aim of contract signature in May 2016. This major milestone for the project is the culmination of the extensive and intense work of many people. This contract will be the largest ever approved by ESO and the largest ever placed for a ground-based telescope. When the contract is signed, ESO will issue a press release with more details, along with extensive information about the design of the dome and telescope structure. No further ...

1 February 2016: On 28 April 2016, ESO will participate in Germany’s Girls’ Day activities, in which technical enterprises, universities and research organisations open their doors to female school students to give them an insight into science and technology professions and to encourage more of them to choose careers in STEM fields (Science, Technology, Engineering and Mathematics). The ESO Girls’ Day will introduce the work of ESO and highlight many of our daily activities, such as astrophysical research, mechanical and opto-mechanical design and integration, operations, and much more. The programme includes an introductory talk, a tour of the main ESO laboratories, and hands-on workshops on astronomy and engineering. The students will learn how astronomical instruments are built, tested and operated. They will also learn how data are collected and used in astronomical research to answer the big questions about the Universe. This will provide the students with an insight into the kinds of ...

1 February 2016: One of ESO’s Photo Ambassadors has joined a select band of people who have photographed a strange phenomenon in the sky, known as Red Sprites. These are not astronomical objects, but occur in the Earth’s atmosphere and are associated with thunderstorms. They are hard to spot, as the conditions need to be right, and they are only visible for a few seconds. But Petr Horálek was in the right place at the right time when he visited ESO’s observatories at La Silla and Paranal in Chile. This ESOcast explores the extraordinary images that result and describes how this ghostly phenomenon comes about. You can subscribe to the ESOcasts in iTunes, receive future episodes on YouTube or follow us on Vimeo. Many other ESOcast episodes are also available.
