24 avril 2020: The contract has been signed for the production of the final set of receivers to be installed on the Atacama Large Millimeter/submillimeter Array (ALMA). ALMA, in which ESO is a partner, observes the Universe at a range of radio wavelengths in the millimetre and submillimetre regions of the electromagnetic spectrum. Each one of ALMA’s 66 antennas is equipped with a number of highly sensitive radio-wave receivers, each receptive to a particular range of wavelengths. The new receivers, called Band 2 receiver cartridges, will allow ALMA to detect wavelengths in the range 2.6 to 4.5 mm. Following successful tests of a prototype Band 2 receiver cartridge, the ALMA board has approved the pre-production phase. This involves a series of six cartridges, with the goal of eventually moving into the production of the full set, one for each of the ALMA antennas. This will depend on the verification of the performance and ...

9 avril 2020: Science observations at ESO’s sites in Chile may have paused last month, but data collected by our telescopes in the past continues to further astronomy years after the observations are conducted. A recently released report by the ESO Library shows that, in 2019 alone, over 1000 publications were published using data from ESO telescopes. The largest contribution to this total comes from ESO’s Very Large Telescope (VLT) and the VLT Interferometer at ESO’s Paranal Observatory in Chile. In 2019, a total of 597 scientific studies were published using data from the facilities. The most productive instruments were UVES, MUSE, and X-shooter with each instrument contributing to over 100 papers individually. A few key results to have come out of ESO’s flagship facility, the VLT, in 2019 included: Finding the first gas giant planet orbiting a Sun-like star remnant and the first detection of a heavy element born in the aftermath ...

19 février 2020: M1, the primary mirror of ESO's Extremely Large Telescope (ELT), is the centrepiece of the revolutionary astronomy machine currently under construction in Chile's Atacama Desert. Too large to be made from a single piece of glass, the 39-metre-diameter mirror will consist of 798 hexagonal segments, each about 5 centimetres thick and measuring 1.4 metres across. Producing 798 segments (plus a few additional pieces) that can work together as a single giant mirror to deliver unprecedented astronomical data is an engineering challenge with milestones worth celebrating. M1 segments begin their life at SCHOTT in Germany as blanks made of Zerodur©, a glass-ceramic material that has very low thermal expansion. After the casting and machining of the blanks to their approximate shape at SCHOTT, the segments are delivered to Safran Reosc, in France. The first 24 segments are currently at Safran Reosc ready to be polished. Polishing facility inaugurated in Poitiers To ...

11 février 2020: Today, the International Day for Women and Girls in Science, we highlight some of the steps ESO has taken towards diversity and inclusion, and how the organisation is celebrating this special day. On 30 January 2020, ESO and UN Women signed a Memorandum of Understanding at ESO’s Vitacura Office in Santiago, Chile, under which ESO stresses its commitment to advancing gender equality, diversity and inclusion. ESO and UN Women Chile will combine forces to promote science and engineering careers among young girls in Chile, as well as to create training opportunities for disadvantaged women who have struggled to finish their formal education. In addition, ESO will use the Women Empowerment Principles as guideposts to structure and measure the progress of its diversity and inclusion actions. The agreement was signed by María Noel Vaeza, UN Women Regional Director for the Americas and the Caribbean, and Xavier Barcons, ESO Director General, in ...

3 février 2020: The French company CILAS has won a multi-million Euro contract with an international organisation thanks in part to technology developed jointly with ESO. “This is a very nice example where ESO invested in technology research and development with a European company and strengthened its capabilities,” says Stefan Ströbele, an expert on deformable mirrors at ESO who worked with CILAS. CILAS, one of ESO's industrial partners and a pioneer in adaptive optics, built deformable mirrors for a number of instruments on ESO telescopes. Many instruments on modern telescopes rely on in-built adaptive optics systems to correct for the effects of atmospheric turbulence. Deformable mirrors are key components of these systems; by means of actuators, their surface can be deformed ever so slightly to compensate for the atmospheric distortion that makes the images fuzzy. To support research and technological development in Europe, and to ensure the availability of necessary technology for ESO ...

31 janvier 2020: ESO’s Extremely Large Telescope (ELT), the world’s biggest eye on the sky, will have a pioneering five-mirror optical system that will allow it to unveil the Universe in unprecedented detail. The tertiary mirror in this system, M3, has completed a key production stage and has now been delivered to French company Safran Reosc for final polishing. Each of the mirrors on the ELT presents a significant technological challenge, with extreme precision required at each production stage to ensure flawless optical quality. The German company SCHOTT produced the mirror blank for M3 — a cast block of a glass-ceramic material known as ZerodurⓇ measuring more than four metres from edge to edge and weighing in at over three tonnes. After casting and machining the M3 blank to its approximate shape, SCHOTT delivered the mirror to Safran Reosc, who will now grind and polish it to a precision of 15 nanometres across ...

21 janvier 2020: MICADO, the first dedicated imaging system for ESO’s Extremely Large Telescope (ELT), has reached an important milestone in its design review. The MICADO consortium, together with a group of external experts from around the world, met at ESO’s Garching headquarters for a week of intense examination of the instrument’s optics, mechanics, software, electronics, and budget plan to identify any areas which needed further design work. After the meeting, the MICADO team addressed all of the major concerns raised during the review and the instrument has now formally passed its preliminary design review. A more detailed design phase is now underway, leading towards the final design review and construction of the instrument’s many components. Equipped for both imaging and spectrographic observations, MICADO — the Multi-Adaptive Optics Imaging Camera for Deep Observations — will focus on near-infrared imaging and spectroscopy with unprecedented combination of sensitivity and accuracy. To compensate for the blurring ...

19 décembre 2019: Several space companies are developing plans for constellations of satellites to put in relatively low Earth orbits, for a variety of communication purposes. The recent launches of multiple batches of satellites for Space X’s Starlink project have drawn public and media attention, particularly as a result of the satellites’ high visibility immediately after launch. The astronomy community has raised concerns about the impact of these constellations on scientific research. In coordination with the International Astronomical Union (IAU), the American Astronomical Society (AAS), and the Royal Astronomical Society (RAS), ESO and other observatories are evaluating the effects that these satellite constellations will have on ground-based optical and infrared astronomical observations. The calculations will soon be made public after undergoing independent peer review. Satellite constellations will have an impact on radio, millimetre and submillimetre observatories, including the Atacama Large Millimeter/submillimeter Array (ALMA) and the Atacama Pathfinder Experiment (APEX). ESO has an observer ...
