30 January 2019: January 2019 marks 50 years since the publication of the first issue of Astronomy & Astrophysics, which ESO played an important role in founding. Since its inception, Astronomy & Astrophysics has become recognised as a prestigious publication counted amongst the top journals in the field. In January 1969 Astronomy & Astrophysics — known as A&A — published its first issue. This debut was achieved within a year of the first meeting of the founders in April 1968. The motivation behind its creation was to unite the individual astronomy publications of the founding European member states into a single larger journal, garnering increased recognition worldwide. In the 50 intervening years, A&A has grown into a highly influential publication. Though itself only a few years older than A&A, ESO played a significant role in its establishment; as an existing European intergovernmental astronomy organisation, ESO was able to lend its legal status to ...

16 January 2019: Work on the elaborate optics of ESO’s 39-metre Extremely Large Telescope (ELT) has taken a major step forwards following the successful casting, annealing, ceramization, machining and acid-etching of the substrate for the ELT’s secondary mirror, M2. This massive 3-ton mirror blank has been successfully machined from a slab of the low-expansion ceramic material ZERODURⓇ into its near-final form by the German company SCHOTT [1]. The creation of this technological masterpiece was a challenging process, requiring state-of-the-art CNC machines to correctly grind the mirror blank. Now, safely stowed in an extra-large transport box, the blank is being shipped to France for final grinding and polishing by Safran Reosc. Despite being the ELT’s secondary mirror, M2 still has an impressive diameter of 4.25 meters — larger than the primary mirror of many astronomical telescopes operating today. Following sixteen months of precision manufacturing at SCHOTT, M2 will now receive its final touches — ...

20 December 2018: Since the ESO Council gave their “green light” to start the construction of the Extremely Large Telescope (ELT) in 2014, the programme has been advancing rapidly. To date, almost 90% (by value) of the external contracts have been awarded for the design and manufacture of the telescope, optics, components and instruments. ESO continuously monitors the performance of ongoing contracts and the schedule of the programme. With the facts available today, ESO has assessed the current situation of the ongoing work and the tight schedule for the products and activities still to be procured. In light of this, ESO has decided to revise the ELT’s baseline schedule. As a result, First Light, previously scheduled for the end of 2024, is currently planned for the end of 2025. Despite the postponement of the First Light, the schedules committed to in all running contracts and agreements with the ELT industrial contractors and institute ...

20 December 2018: HARMONI, one of the first-light instruments for the Extremely Large Telescope (ELT), has successfully completed the Preliminary Design Review process (PDR). During a week of intense discussions with the HARMONI consortium at the end of 2017, ESO and community experts examined whether the instrument could achieve its highly ambitious science goals. They assessed the design of the instrument's optics, mechanics, software, and electronics, as well as its operational concepts — in the process identifying some technical issues which required further work. The HARMONI team has since then completed all the tasks identified by the Review and the instrument has now formally passed its PDR. By completing this vital step, the instrument can progress to the detailed design phase, aiming to be ready for cutting-edge observations when the ELT sees first light. As well as passing this major milestone, HARMONI is also set to gain a powerful new adaptive optics system. ...

11 December 2018: ESO’s fifth Director General, Riccardo Giacconi, passed away on Sunday 9 December 2018 at the age of 87. Riccardo Giacconi led ESO from 1993 to 1999, at a crucial time in the organisation’s history. ESO was constructing what is now its flagship facility, the Very Large Telescope (VLT), on Cerro Paranal, and starting the partnership that would become the Atacama Large Millimeter/submillimeter Array (ALMA). The successes of these years, and in particular the construction of the VLT, put ESO on the path to being the world-leading astronomical organisation that it is today. Riccardo Giacconi was born in Genova, Italy on 6 October 1931. He obtained both a degree in Physics and his PhD from the University of Milan. In 1956, two years after receiving his PhD, Giacconi moved to Indiana University, USA and then on to Princeton University, USA to work at the Princeton Cosmic Ray Laboratory. Following his time ...

7 December 2018: The New Adaptive Optics Module for Interferometry (NAOMI) has seen first light after being installed on all four 1.8-metre Auxiliary Telescopes (ATs) of ESO’s Very Large Telescope Interferometer (VLTI) at the Paranal Observatory in Chile. By introducing state-of-the-art adaptive optics technology, NAOMI has improved the imaging capabilities of the VLTI to unprecedented levels, giving the VLTI’s powerful scientific instruments such as GRAVITY a clearer view of the Universe than ever. The VLTI is a mode of ESO’s Very Large Telescope (VLT) that can combine up to all four ATs or the 8.2-metre Unit Telescopes of the VLT to create a virtual telescope with a diameter of up to 130 metres, allowing incredibly high-resolution observations. Using the VLTI, astronomers can study stellar surfaces, active galactic nuclei, young stars, and a variety of other intriguing astronomical objects. To combat the effects of atmospheric turbulence on the quality of the observations performed by ...
