5 juni 2020: METIS, the powerful imager and spectrograph for ESO’s Extremely Large Telescope (ELT), has passed its Preliminary Design Review at ESO’s headquarters in Garching, Germany. METIS, short for Mid-infrared ELT Imager and Spectrograph, will make full use of the giant main mirror of the telescope to study a wide range of science topics, from objects in our Solar System to distant active galaxies. METIS will be extremely well suited to study the life cycle of stars, from infant stars and planet-forming discs to older stars near the end of their lifetime. The ELT will be the largest optical to mid-infrared telescope on Earth when it starts operations towards the middle of this decade. With its 39-metre primary mirror and advanced adaptive-optics systems, it will have six times the resolution of the James Webb Space Telescope. METIS will take full advantage of this remarkable telescope and its adaptive optics to probe the ...

27 maj 2020: ESO:s teleskop är på jakt efter svaren på några av de största och mest fundamentala av universums mysterier. De bidrar ständigt till ökande kunskaper, även om 95 % av universum är omöjligt att nå med direkta observationer. Ju längre ut i universum vi blickar med våra teleskop, desto mer upptäcker vi, och desto bättre blir förståelsen om universums struktur, innehåll och fysiska lagar. Men fortfarande finns många frågor som vi inte har svar på. Genom att jämföra nya observationer med teorier har vi upptäckt underliga och surrealistiska paradoxer om verkligheten omkring oss. De handlar till exempel om vad universum består av, hur många universa det finns, och vad tid egentligen är. I denna ESOcast undersöker vi tio av de mest fascinerande paradoxerna om vårt universum och de frågor de väcker. Du kan prenumerera på ESOcasts på iTunes eller se ytterligare avsnitt på YouTube. Många ESOcasts kan också ses i ESO:s ...

24 april 2020: Ett kontrakt har undertecknats för att påbörja produktionen av den slutliga uppsättningen av de mottagare som ska installeras på Atacama Large Millimeter/submillimeter Array (ALMA). ALMA, där ESO är en partner, observerar universum i radiovåglängder i millimeter- och submillimeterområdet i det elektromagnetiska spektrat. Alla 66 ALMA-antennerna är utrustade med ett antal högkänsliga radiovågsmottagare som var och en är känslig för ett visst våglängdsområde. De nya mottagarna, så kallade Band 2-kasetter, ger ALMA möjlighet att studera våglängder mellan 2,6 och 4,5 mm. Förproduktionsfasen har nu godkänts av ALMA-kommittén efter lyckade tester av en prototyp av de nya kasetterna. Förproduktionsfasen omfattar sex kasetter med målet att producera ett set för var och en av antennerna. Med de nya mottagarkasetterna kommer ALMA att bli en ännu mer allsidig vetenskapsmaskin. De gör det möjligt att studera det kalla interstellära mediet, den tunna blandning av gas och strålning som finns mellan stjärnorna. ALMA kommer också att ...

9 april 2020: De vetenskapliga studierna på ESO:s observatorier i Chile har nyligen tagit en paus, men data som insamlas med teleskopen fortsätter att ge viktiga bidrag till forskningen många år efter de har samlats in. En nyligen publicerad rapport från ESO:s bibliotek visar att ESO fortsätter att vara det mest produktiva markbaserade observatoriet i världen, med över 1 000 publicerade vetenskapliga artiklar under 2019. Det största bidraget kommer från ESO:s Very Large Telescope (VLT) och VLT-interferometern vid ESO:s Paranalobservatorium i Chile. Under 2019 publicerades 519 artiklar med resultat från Paranal. De mest produktiva instrumenten var UVES, MUSE och X-shooter, vilka vardera bidrog med data till över 100 artiklar. Några särskilt intressanta resultat under året producerades med VLT, bland andra den första gasjätteplaneten som kretsar kring en sollik stjärnrest och den första detektionen av ett tungt grundämne som har uppstått i vid en kollision av två neutronstjärnor. ESO:s övriga teleskop vid Paranal, VISTA ...

19 februari 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 februari 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 februari 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 januari 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 januari 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 ...
