5 november 2019: ESO is taking important steps to make its revolutionary new ground-based telescope greener. Next year, a power conditioning system and a photovoltaic plant will be installed at the site of ESO’s Extremely Large Telescope (ELT) with operations of both systems starting 2 years later. One of the biggest challenges in the construction of ESO’s ELT in Cerro Armazones, Antofagasta, Chile, is to ensure access to a clean and highly reliable electrical supply. Since the telescope is located close to areas that receive some of the highest amounts of solar radiation in the world, this goal can be achieved by installing and operating a power conditioning system to the grid supply and a photovoltaic plant, independent from the grid generator. Today, ESO signed a contract with the company SAESA to install and operate both facilities. The electrical power conditioning system will provide highly reliable electricity, will have full backup capacity, and ...

23 oktober 2019: Recent developments in Chile have led to disruptions of some services, including transportation and flight cancellations, affecting the normal function of some Chilean cities. ESO is monitoring the situation closely and has implemented measures to continue to ensure the well-being of its staff and visitors. ESO travel to and within Chile has been limited, and this may have an impact on ESO operations in Vitacura, La Silla, Paranal and APEX.

22 oktober 2019: Den 2 juli 2019 var en total solförmörkelse synlig från ESO:s La Sillaobservatorium i Chiles Atacamaöknen. Totala solförmörkelser är ovanliga fenomen som sker på en given plats med omkring 360 års mellanrum och som starkt påverkar dem som ser den. Ännu ovanligare är det att en total solförmörkelse passerar rakt över ett astronomiskt observatorium där dedikerade vetenskapliga experiment kan genomföras. Av denna anledning bjöd ESO in 25 forskare, kommunikatörer och pedagoger för att observera och dokumentera händelsen. Med de experiment som genomfördes kunde bland annat solkoronans polarisation mätas och spektra av solkoronan tas. Som ett minne av denna speciella händelse har ESO producerat en ny video, ESOcast 209. I denna kan du återuppleva den totala solförmörkelsen på La Silla och se hur astronomerna använde denna händelse för att lära sig mer om vår närmaste stjärna. Läs The Messenger no. 177 för mer information om de experiment som genomfördes. Du kan ...

30 september 2019: The newest addition to the ESO Supernova Planetarium & Visitor Centre’s programme, the show Out There — The Quest for Extrasolar Worlds, invites you to discover humanity’s quest for life on other planets, as we try to understand whether life in the Universe is the norm or the exception. Are you curious to learn how science caught up with fiction, what planets we first explored and how we discover new extrasolar planets nowadays? Then book your place at a show starting on 28 October 2019, in either German or English. For thousands of years, mankind thought that the Earth was the centre of the Universe. Thanks to our curiosity, imagination and urge to explore, we now know that planets around stars are nothing special in the cosmos. The Sun is just one ordinary star among hundreds of billions in our galaxy, the Milky Way. With the world’s most powerful telescopes ...

27 september 2019: Construction is now underway of the foundation of ESO’s Extremely Large Telescope (ELT) in the remote Chilean Atacama Desert. Once complete, the telescope will be the largest ground-based telescope in operation, weighing in at 3400 tonnes. The ELT is a reflecting, fully-steerable telescope. The design includes a segmented primary mirror measuring 39.3 metres in diameter, a secondary mirror (4.2 metres in diameter) and a tertiary mirror (3.75 metres in diameter). The telescope will also feature groundbreaking adaptive optics technology that will help correct the distortions in Earth’s atmosphere, making the images sharper than those taken from space. The enclosure itself will be a classic dome shape and will be the telescope’s first defence against the elements. The dome height comes in at nearly 74 metres from the ground and it will span 86 metres in diameter. Since the ELT is the largest telescope ever built to date — the question ...

Competition judge Ed Robinson said: “For a single multiple-exposure image to capture this event with such positional precision, creative innovation and beauty is nothing short ...

9 september 2019: The Event Horizon Telescope (EHT) Collaboration, the team who captured an image of a black hole for the first time, has been awarded the 2020 Breakthrough Prize in Fundamental Physics in recognition of this achievement. The feat used an Earth-scale array of eight ground-based radio telescopes, including two in which ESO is a major partner: the Atacama Large Millimeter/submillimeter Array (ALMA) and the Atacama Pathfinder Experiment (APEX). Three current and recent ESO employees are among the scientists who will share in the prize. The ALMA and APEX telescopes [1][2] location in Chile were indispensable in achieving the unprecedented resolution required for this breakthrough. The large combined collecting area of ALMA's antennas also made it the most sensitive facility in the EHT by far, and a key part of the entire network, enabling the EHT to capture ten times fainter signals. The Breakthrough Prize Foundation and its founding sponsors — Sergey ...

27 augusti 2019: ESO’s longest-serving Director General, Lodewijk Woltjer, passed away on Sunday 25 August 2019 at the age of 89. Lodewijk Woltjer, known to many as Lo, was ESO’s third and longest-serving Director General, from 1975 to 1987. He had a strong vision for ESO’s future before he even took up the position as Director General, and one of the most significant imprints he left on ESO was the establishment of a science group, which transformed it from a purely functional observatory into an active scientific research organisation. In addition to this fundamental shift and expansion of ESO’s work, Prof. Woltjer oversaw many important developments during his tenure. These included the inauguration of the Garching Headquarters and addition of two new member states, Italy and Switzerland, in 1982. He signed an agreement with the director of the Max Planck Institute for Astronomy to install what is now known as the MPG/ESO 2.2-metre ...
