    ESO’s Very Large Telescope (VLT) has recently received an upgraded addition to its suite of advanced instruments. On 21 May 2019 the newly modified instrument VISIR (VLT Imager and Spectrometer for mid-Infrared) made its first observations since being modified to aid in the search for potentially habitable planets in the Alpha Centauri system, the closest star system to Earth. This image shows NEAR mounted on UT4, with the telescope inclined at low altitude.

    Newly-built planet-finding instrument installed on Very Large Telescope, Chile, begins 100-hour observation of nearby stars Alpha Centauri A and B, aiming to be first to directly image a habitable exoplanet.

    Breakthrough Watch, the global astronomical program looking for Earth-like planets around nearby stars, and the European Southern Observatory (ESO), Europe’s foremost intergovernmental astronomical organisation, today announced “first light” on a newly-built planet-finding instrument at ESO’s Very Large Telescope in the Atacama Desert, Chile.

    The instrument, called NEAR (Near Earths in the AlphaCen Region), is designed to hunt for exoplanets in our neighbouring star system, Alpha Centauri, within the “habitable zones” of its two Sun-like stars, where water could potentially exist in liquid form. It has been developed over the last three years and was built in collaboration with the University of Uppsala in Sweden, the University of Liège in Belgium, the California Institute of Technology in the US, and Kampf Telescope Optics in Munich, Germany.

    Since 23 May ESO’s astronomers at ESO’s Very Large Telescope (VLT) have been conducting a ten-day observing run to establish the presence or absence of one or more planets in the star system. Observations will conclude tomorrow, 11 June. Planets in the system (twice the size of Earth or bigger), would be detectable with the upgraded instrumentation. The near- to thermal-infrared range is significant as it corresponds to the heat emitted by a candidate planet, and so enables astronomers to determine whether the planet’s temperature allows liquid water.

    Alpha Centauri is the closest star system to our Solar System, at 4.37 light-years (about 25 trillion miles) away. It consists of two Sun-like stars, Alpha Centauri A and B, plus the red dwarf star, Proxima Centauri. Current knowledge of Alpha Centauri’s planetary systems is sparse. In 2016, a team using ESO instruments discovered one Earth-like planet orbiting Proxima Centauri. But Alpha Centauri A and B remain unknown quantities; it is not clear how stable such binary star systems are for Earth-like planets, and the most promising way to establish whether they exist around these nearby stars is to attempt to observe them.

    Imaging such planets, however, is a major technical challenge, since the starlight that reflects off them is generally billions of times dimmer than the light coming to us directly from their host stars; resolving a small planet close to its star at a distance of several light-years has been compared to spotting a moth circling a street lamp dozens of miles away. To solve this problem, in 2016 Breakthrough Watch and ESO launched a collaboration to build a special instrument called a thermal infrared coronagraph, designed to block out most of the light coming from the star and optimised to capture the infrared light emitted by the warm surface of an orbiting planet, rather than the small amount of starlight it reflects. Just as objects near to the Sun (normally hidden by its glare) can be seen during a total eclipse, so the coronagraph creates a kind of artificial eclipse of its target star, blocking its light and allowing much dimmer objects in its vicinity to be detected. This marks a significant advance in observational capabilities.

    The coronagraph has been installed on one of the VLT’s four 8-metre-aperture telescopes, upgrading and modifying an existing instrument, called VISIR, to optimise its sensitivity to infrared wavelengths associated with potentially habitable exoplanets.

    ESO’s Very Large Telescope (VLT) has recently received an upgraded addition to its suite of advanced instruments. On 21 May 2019 the newly modified instrument VISIR (VLT Imager and Spectrometer for mid-Infrared) made its first observations since being modified to aid in the search for potentially habitable planets in the Alpha Centauri system, the closest star system to Earth. This image shows the NEAR experiment being mounted on the Cassegrain focus of the VLT’s UT4.

    It will therefore be able to search for heat signatures similar to that of the Earth, which absorbs energy from the Sun and emits it in the thermal infrared wavelength range. NEAR modifies the existing VISIR instrument in three ways, combining several cutting-edge astronomical engineering achievements. First, it adapts the instrument for coronagraphy, enabling it to drastically reduce the light of the target star and thereby reveal the signatures of potential terrestrial planets. Second, it uses a technique called adaptive optics to strategically deform the telescope’s secondary mirror, compensating for the blur produced by the Earth’s atmosphere. Third, it employs novel chopping strategies that also reduce noise, as well as potentially allowing the instrument to switch rapidly between target stars -— as fast as every 100 milliseconds — maximising the available telescope time.

    Pete Worden, Executive Director of the Breakthrough Initiatives, said: “We’re delighted to collaborate with the ESO in designing, building, installing and now using this innovative new instrument. If there are Earth-like planets around Alpha Centauri A and B, that’s huge news for everyone on our planet.”

    “ESO is glad to bring its expertise, existing infrastructure, and observing time on the Very Large Telescope to the NEAR project,” commented ESO project manager Robin Arsenault.

    “This is a valuable opportunity, as — in addition to its own science goals — the NEAR experiment is also a pathfinder for future planet-hunting instruments for the upcoming Extremely Large Telescope,” says Markus Kasper, ESO’s lead scientist for NEAR.

    “NEAR is the first and (currently) only project that could directly image a habitable exoplanet. It marks an important milestone. Fingers crossed — we are hoping a large habitable planet is orbiting Alpha Cen A or B” commented Olivier Guyon, lead scientist for Breakthrough Watch.

    “Human beings are natural explorers,” said Yuri Milner, founder of the Breakthrough Initiatives, “It is time we found out what lies beyond the next valley. This telescope will let us gaze across.”

    Notes

    The data from the NEAR experiment are publicly available from the ESO archive under programme ID 2102.C-5011. A pre-processed and condensed package of all the data will be made available shortly after the campaign concludes. In addition, the Python-based high-contrast imaging data reduction tool PynPoint has been adapted to process NEAR data, and will be provided to members of the astronomical community who would like to use the data but do not have their own data reduction tools. https://pynpoint.readthedocs.io/en/latest/near.html

    Breakthrough Watch is a global astronomical programme aiming to identify and characterise planets around nearby stars. The programme is run by an international team of experts in exoplanet detection and imaging. https://breakthroughinitiatives.org/initiative/4

    The Breakthrough Initiatives are a suite of scientific and technological programmes, founded by Yuri Milner, investigating life in the Universe. Along with Breakthrough Watch, they include Breakthrough Listen, the largest ever astronomical search for signs of intelligent life beyond Earth, and Breakthrough Starshot, the first significant attempt to design and develop a space probe capable of reaching another star.

    ESO is the foremost intergovernmental astronomy organisation in Europe and the world’s most productive ground-based astronomical observatory by far. It is supported by 16 countries: Austria, Belgium, Brazil, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom, along with the host state of Chile. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. ESO also plays a leading role in promoting and organising cooperation in astronomical research. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope, the world’s most advanced visible-light astronomical observatory and two survey telescopes. VISTA works in the infrared and is the world’s largest survey telescope and the VLT Survey Telescope is the largest telescope designed to exclusively survey the skies in visible light. ESO is a major partner in ALMA, the largest astronomical project in existence. And on Cerro Armazones, close to Paranal, ESO is building the 39-metre EEuropean Extremely Large Telescope, the E-ELT, which will become “the world’s biggest eye on the sky”.

    From European Southern Observatory: “ESO contributes to protecting Earth from dangerous asteroids”

    VLT observes a passing double asteroid hurtling by Earth at 70 000 km/h.

    1
    The unique capabilities of the SPHERE instrument on ESO’s Very Large Telescope have enabled it to obtain the sharpest images of a double asteroid as it flew by Earth on 25 May. While this double asteroid was not itself a threatening object, scientists used the opportunity to rehearse the response to a hazardous Near-Earth Object (NEO), proving that ESO’s front-line technology could be critical in planetary defence.

    ESO SPHERE extreme adaptive optics system and coronagraphic facility on the extreme adaptive optics system and coronagraphic facility on the VLT MELIPAL UT3, Cerro Paranal, Chile, with an elevation of 2,635 metres (8,645 ft) above sea level

    The International Asteroid Warning Network (IAWN) coordinated a cross-organisational observing campaign of the asteroid 1999 KW4 as it flew by Earth, reaching a minimum distance of 5.2 million km [1] on 25 May 2019. 1999 KW4 is about 1.3 km wide, and does not pose any risk to Earth. Since its orbit is well known, scientists were able to predict this fly-by and prepare the observing campaign.

    ESO joined the campaign with its flagship facility, the Very Large Telescope (VLT). The VLT is equipped with SPHERE [above] — one of the very few instruments in the world capable of obtaining images sharp enough to distinguish the two components of the asteroid, which are separated by around 2.6 km.

    SPHERE was designed to observe exoplanets; its state-of-the-art adaptive optics (AO) system corrects for the turbulence of the atmosphere, delivering images as sharp as if the telescope were in space. It is also equipped with coronagraphs to dim the glare of bright stars, exposing faint orbiting exoplanets.

    Taking a break from its usual night job hunting exoplanets, SPHERE data helped astronomers characterise the double asteroid. In particular, it is now possible to measure whether the smaller satellite has the same composition as the larger object.

    “These data, combined with all those that are obtained on other telescopes through the IAWN campaign, will be essential for evaluating effective deflection strategies in the event that an asteroid was found to be on a collision course with Earth,” explained ESO astronomer Olivier Hainaut. “In the worst possible case, this knowledge is also essential to predict how an asteroid could interact with the atmosphere and Earth’s surface, allowing us to mitigate damage in the event of a collision.”

    “The double asteroid was hurtling by the Earth at more than 70 000 km/h, making observing it with the VLT challenging,” said Diego Parraguez, who was piloting the telescope. He had to use all his expertise to lock on to the fast asteroid and capture it with SPHERE.

    Bin Yang, VLT astronomer, declared “When we saw the satellite in the AO-corrected images, we were extremely thrilled. At that moment, we felt that all the pain, all the efforts were worth it.” Mathias Jones, another VLT astronomer involved in these observations, elaborated on the difficulties. “During the observations the atmospheric conditions were a bit unstable. In addition, the asteroid was relatively faint and moving very fast in the sky, making these observations particularly challenging, and causing the AO system to crash several times. It was great to see our hard work pay off despite the difficulties!”

    While 1999 KW4 is not an impact threat, it bears a striking resemblance to another binary asteroid system called Didymos which could pose a threat to Earth sometime in the distant future.

    Didymos and its companion called “Didymoon” are the target of a future pioneering planetary defence experiment. NASA’s DART spacecraft will impact Didymoon in an attempt to change its orbit around its larger twin, in a test of the feasibility of deflecting asteroids.

    After the impact, ESA’s Hera mission will survey the Didymos asteroids in 2026 to gather key information, including Didymoon’s mass, its surface properties and the shape of the DART crater.

    ESA’s proposed Hera spaceraft

    The success of such missions depends on collaborations between organisations, and tracking Near-Earth Objects is a major focus for the collaboration between ESO and ESA. This cooperative effort has been ongoing since their first successful tracking of a potentially hazardous NEO in early 2014.

    “We are delighted to be playing a role in keeping Earth safe from asteroids,” said Xavier Barcons, ESO’s Director General. “As well as employing the sophisticated capabilities of the VLT, we are working with ESA to create prototypes for a large network to take asteroid detection, tracking and characterization to the next level.”

    This recent close encounter with 1999 KW4 comes just a month before Asteroid Day, an official United Nations day of education and awareness about asteroids, to be celebrated on 30 June. Events will be held on five continents, and ESO will be among the major astronomical organisations taking part. The ESO Supernova Planetarium & Visitor Centre will host a range of activities on the theme of asteroids on the day, and members of the public are invited to join in the celebrations.
    Notes

    [1] This distance is about 14 times the distance to the Moon — close enough to study, but not close enough to be threatening! Many small asteroids fly past the Earth much closer than 1999 KW4, occasionally closer than the Moon. Earth’s most recent encounter with an asteroid took place on 15 February 2013, when a previously unknown asteroid 18 metres across exploded as it entered Earth’s atmosphere over the Russian city of Chelyabinsk. The damage produced by the subsequent shockwave caused injuries to about 1,500 people.

    Successful proposals include projects highlighting societal benefits of ESO technology.

    1
    ATTRACT, a Horizon 2020 research and innovation project funded by the European Union and backed by a consortium of 9 partners including ESO, has announced 170 breakthrough ideas which will each receive €100,000 to develop technologies that have the potential to change society. The selected proposals include projects which highlight the societal benefits of ESO’s astronomical expertise.

    The projects selected for funding were drawn from a pool of more than 1200 proposals from researchers and entrepreneurs in scientific and industrial organisations across the world. An independent Research, Development and Innovation (R&D&I) Committee used a rigorous evaluation process to determine which of these proposals should receive €100,000 of funding.

    “170 breakthrough ideas were selected based on a combination of scientific merit, innovation readiness and potential societal impact,” explained Sergio Bertolucci, chair of ATTRACT’s R&D&I Committee. “The idea is to speed up the process of developing breakthrough technologies and applying them to address society’s key challenges.”

    ESO’s role as a partner in the ATTRACT consortium reflects its ongoing commitment to using astronomical technology to address societal challenges. The following selected ATTRACT projects highlight some of the societal applications of ESO’s astronomical technology and expertise:

    3D-CANCER-SPEC will bring astronomical technology to bear against cancer, one of the leading cause of death worldwide. This project — coordinated by Martin Roth of innoFSPEC at the Leibniz-Institut für Astrophysik Potsdam — will combine the expertise of two partners involved in the development of the innovative MUSE instrument on ESO’s Very Large Telescope. By doing so, the team will carry out a design study for an imaging spectrograph suitable for clinical cancer studies.

    Spectroscopy is a powerful technique that can be used to determine the composition of an object from the light it emits, whether that light comes from an object in space or a person’s body on Earth. Cancerous tissue differs enough from healthy tissue that it can be distinguished using Raman Spectroscopy — providing a promising way to avoid taking invasive tissue samples. While this has previously been shown to work in principle, the imaging process took hours, which is far too long to be practically useful. To make this process fast enough in a clinical setting, the team plans to apply a special technique of integral-field spectroscopy — as used by MUSE — developed to solve a particular challenge of astronomical imaging.

    ESO MUSE on the VLT on Yepun (UT4)

    Single Photon Visible Light Image Sensors for Science and Technology seeks to lay the foundations for transformational changes in low-light imaging. This project, coordinated by Konstantin Stefanov of the Open University in partnership with ESO detector specialist Mark Downing, aims to develop single-photon visible-light imagers, suitable for adaptive optics systems and low-light level spectroscopic and imaging applications. The imaging performance of such sensors would be limited only by the photon absorption in the semiconductor and the quantum nature of light. By detecting and counting each and every photon without registering any additional noise, these sensors could offer the ultimate imaging performance — helping us see and discover the unknown.

    “It’s wonderful to see how this technology used in ESO’s telescope instruments can be applied in a completely different field,” commented Andrew Williams, ESO’s representative on the ATTRACT Executive Board. “This is a key goal of the ATTRACT project, which provides seed funding to enable such ideas and continues the long tradition of fundamental research leading to innovative technologies that benefit society.”

    From augmented reality to smart sensors and devices, many of the 170 ideas chosen will develop disruptive technologies that could help improve clinical diagnosis, health monitoring and personalised treatments for diseases such as cancer, Alzheimer’s, or malaria, as well as heart and neurological conditions.

    Interdisciplinary teams of researchers, entrepreneurs and companies from across the globe will also develop novel sensors and devices that will enable radical innovations in many other sectors with high market potential. New technologies will include smart devices for environmental monitoring, green solutions to fight climate change, advanced applications for citizens, smart systems for manufacturing processes, and disruptive technologies to expand our scientific knowledge.

    Details of the 170 funded projects are being released today, and are grouped into four broad categories: data acquisition systems and computing; front-end and back-end electronics; sensors; and software and integration.

    Most of the breakthrough ideas — 64% — will develop next-generation technologies involving sensors, 16% will focus on data-acquisition systems and computing, 12% are software and integration projects, and 8% will develop the front and back-end electronics needed for the interfaces of sensors and imaging technology.

    The 170 breakthrough projects funded by ATTRACT [1] will have one year to show that their disruptive ideas are worth further investment, and will present their results at a conference in autumn 2020 in Brussels. During the one-year development phase, business and innovation experts from the ATTRACT Project Consortium’s Aalto University, EIRMA, and ESADE Business School will help the project teams explore how their breakthrough technologies can be transformed into innovations with strong market potential.
    Notes

    [1] The ATTRACT initiative involves the European Organization for Nuclear Research (CERN), the European Molecular Biology Laboratory (EMBL), the European Southern Observatory (ESO), the European Synchrotron Radiation Facility (ESRF), the European XFEL, Institut Laue-Langevin (ILL), Aalto University, the European Industrial Research Management Association (EIRMA) and ESADE. The initiative is led by CERN and is funded by the European Union’s Horizon 2020 research and innovation programme.

    ESO is the foremost intergovernmental astronomy organisation in Europe and the world’s most productive ground-based astronomical observatory by far. It is supported by 16 countries: Austria, Belgium, Brazil, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom, along with the host state of Chile. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. ESO also plays a leading role in promoting and organising cooperation in astronomical research. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope, the world’s most advanced visible-light astronomical observatory and two survey telescopes. VISTA works in the infrared and is the world’s largest survey telescope and the VLT Survey Telescope is the largest telescope designed to exclusively survey the skies in visible light. ESO is a major partner in ALMA, the largest astronomical project in existence. And on Cerro Armazones, close to Paranal, ESO is building the 39-metre EEuropean Extremely Large Telescope, the E-ELT, which will become “the world’s biggest eye on the sky”.

    Cherenkov Telescope Array rendering

    ESO today officially became a shareholder of the Cherenkov Telescope Array Observatory gGmbH (CTAO). The necessary formal steps were concluded during the meeting of the CTA Council on 7–8 March at ESO’s headquarters in Garching bei München, Germany after ESO participating in the project for some time as an observer. The Cherenkov Telescope Array (CTA) is the next-generation ground-based observatory designed to detect very high energy gamma-rays. When completed, the array will comprise 118 telescopes shared between sites in the northern and southern hemispheres.

    ESO already signed an agreement on 19 December 2018 to host the southern site of the CTA in the Atacama desert near the ESO Paranal Observatory in Chile. The Paranal site, home of the Very Large Telescope, offers excellent viewing conditions and well-established infrastructure, making it an attractive location for new facilities such as CTA–South. The northern site of the CTA will be based on La Palma in the Canary Islands.

    As a shareholder, ESO will be represented at the CTA Council, which shall govern the observatory, joining shareholders from 11 countries and associate members from another two. The current legal entity is the CTAO gGmbH, a German non-profit limited liability company. The participating countries are currently in the process of establishing the CTAO European Research Infrastructure Consortium (CTAO ERIC) which will construct, commission and operate the immense observatory.

    The CTA is a huge international project, benefitting from the input of over 1400 scientists and engineers from across five continents. It will be the world’s largest high energy gamma-ray observatory and, with its unique sensitivity at these wavelengths, aims to probe the extreme environments that are the sources of gamma-rays, including pulsars and supernova remnants. It will provide unprecedented insights into the origin and role of relativistic cosmic particles.

    ESO’s observatories operate a suite of the most advanced ground-based astronomical telescopes in the world, providing researchers with state-of-the-art facilities to study the Universe. Observing time on the telescopes is highly sought-after due to the remarkable detail in which they can capture the sky.

    Every year, ESO receives thousands of observing proposals from researchers across the globe – up to ten times more hours of observations than are actually available. ESO therefore has to decide which cutting-edge astronomical questions should be awarded valuable telescope time .

    In this ESOcast, six of the astronomers who help to make these decisions tell us about the hottest topics in contemporary astronomy. Covering topics ranging from dark matter to exoplanets, these astronomers make the case for why these cutting-edge fields deserve time at ESO’s telescopes.

    From European Southern Observatory: “NGC 6902 Caught by SPECULOOS” First Light 

    ESO 50 Large

    From European Southern Observatory

    1
    This Picture of the Week is a special treat: a first-light image from the newest resident of ESO’s Paranal Observatory, the SPECULOOS Southern Observatory. This planet-hunting machine aims to observe nearby but dim stars to locate exoplanets for other telescopes — such as ESO’s forthcoming Extremely Large Telescope (ELT) — to study in detail. Comprising four one-metre telescopes, each named after one of Jupiter’s Galilean moons, SPECULOOS promises to open up new frontiers in exoplanet research.

    This image, however, is obviously not of a faint star, but of a galaxy called NGC 6902. Before a telescope starts its primary mission it must successfully undertake an event called “first light”: the first time it is used for a scientific observation. Astronomers typically pick well-known objects for this initial test of a telescope’s capabilities, which is half demonstration and half celebration. In this case, the team settled on NGC 6902 as the first-light target for the Ganymede telescope.

    The result was this stunning image of the spiral galaxy, which is found about 120 million light-years from Earth in the constellation of Sagittarius (The Archer). The galaxy’s spiral arms swirl outwards from a bright centre until they dissolve into streams of blue haze at the galaxy’s edge. If this is what Ganymede can produce as its first observation of something it wasn’t even designed to image, we have a lot to look forward to. Watch this space!

    Distant lights from Las Campanas Observatory by Ricardo García

    Fifty years ago, when the first international observatories were installed in Chile, light pollution seemed unthinkable due to the low population density and small size of villages and mining sites in the Atacama Desert. A few decades later, Chile’s economic growth has brought it to the brink of becoming a developed country. This is great for our operations at Las Campanas Observatory (LCO) because of improved communications, energy, and transportation infrastructure, as well as a better prepared local workforce. But with this development comes the threat of light pollution.

    Carnegie Las Campanas Observatory in the southern Atacama Desert of Chile in the Atacama Region approximately 100 kilometres (62 mi) northeast of the city of La Serena,near the southern end and over 2,500 m (8,200 ft) high

    Carnegie 6.5 meter Magellan Baade and Clay Telescopes located at Carnegie’s Las Campanas Observatory, Chile. over 2,500 m (8,200 ft) high

    While 50 years ago the main astronomical sites in Chile all had virgin skies, the luminous haloes of growing cities, highways, and mining sites, are starting to have an impact on the sky’s brightness. Currently the Las Campanas sky towards the zenith (that’s looking straight up) is two percent brighter than natural levels. According to simulations based on nighttime satellite imagery, half of this artificial brightness comes from a single source near the observatory: the new lighting system of the Pan-American Highway between La Serena and Vallenar.

    Don’t get me wrong! LCO is still one of the darkest and best sites on the planet for astronomy, but the evolution of light pollution, and the fact that single large projects can have a measurable effect is a bit worrisome and must be addressed. Imagine you are hiking a trail in Yosemite and you find a plastic bag with trash. That doesn’t make Yosemite a polluted park, but a place where action should taken to prevent littering to preserve its beauty. That is exactly what a team of Carnegie astronomers with representatives from other U.S. and European observatories in Chile are doing: raising awareness in the communities and helping the Chilean government in preservation efforts to allow us to have dark skies above the Atacama Desert for generations to come.

    The Carnegie Observatories in a collaboration with the European Southern Observatory (ESO), the Association of Universities for Research in Astronomy (AURA), the Giant Magellan Telescope Organization (GMTO), and the Chilean Government, fund and run the Office for the Protection of the Dark Skies of Chile (OPCC for its acronym in Spanish).

    Via the OPCC, we have helped Chile to be in the forefront of light pollution regulation and dark skies preservation. Since 1998, Chile has one of the world’s most stringent regulations controlling outdoor lighting in regions of astronomical interest. In 2014, these regulations were updated to properly address the use of new technologies like LED lighting. The OPCC also runs education and public outreach projects to raise awareness about light pollution and sustainable illumination practices, and organizes scientific workshops bringing together expertise on light pollution across different areas such as astronomy, medicine, biology, energy efficiency, public policy, etc.

    Chilean authorities can advance the protection of these natural laboratories, which are unique in the world. This requires an increase in the levels of compliance with current light pollution regulations and promoting new initiatives, such as the declaration of protected areas in the lands that surround astronomical observatories. It is also essential to establish a requirement to address light pollution in the environmental impact assessments, which are required for the approval of large construction and infrastructure projects like the Pan-American Highway.

    Last October, Carnegie astronomers and our OPCC partners met with the Chilean Minister of the Environment, Carolina Schmidt, in Cerro Paranal. LCO Director, Leopoldo Infante, and myself had the opportunity to talk personally with Minister Schmidt and present the need for Chile to protect the scientific, cultural, and environmental heritage that the dark skies of the Atacama Desert represent. This was just the latest in a series of activities and initiatives involving Carnegie astronomers in Chile, aimed at advocating for the protection of these magical and valuable sites. Protecting the skies above astronomical observatories will ensure that humanity can continue discovering and understanding the universe for generations to come. We were pleased that the minister stated a strong commitment to help us move forward on these issues. In the meantime, we will remain active and vigilant in the protection of our starry nights.

    Andrew Carnegie established a unique organization dedicated to scientific discovery “to encourage, in the broadest and most liberal manner, investigation, research, and discovery and the application of knowledge to the improvement of mankind…” The philosophy was and is to devote the institution’s resources to “exceptional” individuals so that they can explore the most intriguing scientific questions in an atmosphere of complete freedom. Carnegie and his trustees realized that flexibility and freedom were essential to the institution’s success and that tradition is the foundation of the institution today as it supports research in the Earth, space, and life sciences.

    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 the VLTI, ESO has developed the new adaptive optics system named NAOMI. The system was constructed to improve the sensitivity and performance of the VLT’s ATs in collaboration with the Institut de Planétologie et d’Astrophysique de Grenoble (Centre National de la Recherche Scientifique/Université Grenoble Alpes).

    Developing NAOMI was a tremendously technically challenging endeavour. “The newly installed modules have to concentrate light into optical fibres only a few microns wide — barely a tenth of the width of a human hair!” explained Jean-Philippe Berger of the IPAG. “We also faced the formidable challenge of installing the four adaptive optics systems as quickly as possible in order not to disturb VLTI observations.”

    Previously, the ATs were equipped with the less sophisticated STRAP system (System for Tip/tilt Removal with Avalanche Photodiodes), which observed the effects of atmospheric turbulence and corrected the tilt of the received wavefronts by rapidly adjusting a steering mirror. Despite the valuable corrections it provided under good atmospheric conditions, image quality decreased significantly when conditions were poor.

    “Observing with the VLTI on the ATs was heavily dependent on atmospheric conditions and after every sunset we would anxiously wait to see if it would be a lucky night,” explained Julien Woillez, the VLTI Project Scientist. “NAOMI is changing all this — we can now observe efficiently even in less good seeing conditions.”

    By using an advanced adaptive optics system [1], NAOMI will improve the precision of the measurements performed by the VLTI and achieve a better and more stable image quality. The VLTI’s razor-sharp new adaptive optics will enable efficient, long integrations even in degraded seeing — bringing out the best of the VLTI instruments under all atmospheric conditions.

    “On some nights it looks like the atmosphere is virtually gone! We can now observe much fainter objects,” concluded Woillez. “With NAOMI, we can now use cutting-edge second-generation instruments like PIONIER, GRAVITY, and MATISSE to their full potential.”
    Notes

    [1] A key component of the NAOMI module is a deformable mirror from the company ALPAO — in a feat of optical engineering, the shape of this mirror is updated 500 times per second, ensuring that the VLTI’s view is almost free of atmospheric turbulence.

    ESO is the foremost intergovernmental astronomy organisation in Europe and the world’s most productive ground-based astronomical observatory by far. It is supported by 16 countries: Austria, Belgium, Brazil, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom, along with the host state of Chile. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. ESO also plays a leading role in promoting and organising cooperation in astronomical research. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope, the world’s most advanced visible-light astronomical observatory and two survey telescopes. VISTA works in the infrared and is the world’s largest survey telescope and the VLT Survey Telescope is the largest telescope designed to exclusively survey the skies in visible light. ESO is a major partner in ALMA, the largest astronomical project in existence. And on Cerro Armazones, close to Paranal, ESO is building the 39-metre EEuropean Extremely Large Telescope, the E-ELT, which will become “the world’s biggest eye on the sky”.

    The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth — a so-called super-Earth. One of the largest observing campaigns to date using data from a world-wide array of telescopes, including ESO’s planet-hunting HARPS instrument [below], have revealed this frozen, dimly lit world. The newly discovered planet is the second-closest known exoplanet to the Earth. Barnard’s star is the fastest moving star in the night sky.

    A planet has been detected orbiting Barnard’s Star, a mere 6 light-years away. This breakthrough — announced in a paper published today in the journal Nature — is a result of the Red Dots and CARMENES projects, whose search for local rocky planets has already uncovered a new world orbiting our nearest neighbour, Proxima Centauri.

    The planet, designated Barnard’s Star b, now steps in as the second-closest known exoplanet to Earth [1]. The gathered data indicate that the planet could be a super-Earth, having a mass at least 3.2 times that of the Earth, which orbits its host star in roughly 233 days. Barnard’s Star, the planet’s host star, is a red dwarf, a cool, low-mass star, which only dimly illuminates this newly-discovered world. Light from Barnard’s Star provides its planet with only 2% of the energy the Earth receives from the Sun.

    Despite being relatively close to its parent star — at a distance only 0.4 times that between Earth and the Sun — the exoplanet lies close to the snow line, the region where volatile compounds such as water can condense into solid ice. This freezing, shadowy world could have a temperature of –170 ℃, making it inhospitable for life as we know it.

    Named for astronomer E. E. Barnard, Barnard’s Star is the closest single star to the Sun. While the star itself is ancient — probably twice the age of our Sun — and relatively inactive, it also has the fastest apparent motion of any star in the night sky [2]. Super-Earths are the most common type of planet to form around low-mass stars such as Barnard’s Star, lending credibility to this newly discovered planetary candidate. Furthermore, current theories of planetary formation predict that the snow line is the ideal location for such planets to form.

    Previous searches for a planet around Barnard’s Star have had disappointing results — this recent breakthrough was possible only by combining measurements from several high-precision instruments mounted on telescopes all over the world [3].

    “After a very careful analysis, we are 99% confident that the planet is there,” stated the team’s lead scientist, Ignasi Ribas (Institute of Space Studies of Catalonia and the Institute of Space Sciences, CSIC in Spain). “However, we’ll continue to observe this fast-moving star to exclude possible, but improbable, natural variations of the stellar brightness which could masquerade as a planet.”

    Among the instruments used were ESO’s famous planet-hunting HARPS and UVES spectrographs.

    “HARPS played a vital part in this project. We combined archival data from other teams with new, overlapping, measurements of Barnard’s star from different facilities,” commented Guillem Anglada Escudé (Queen Mary University of London), co-lead scientist of the team behind this result [4]. “The combination of instruments was key to allowing us to cross-check our result.”

    The astronomers used the Doppler effect to find the exoplanet candidate. While the planet orbits the star, its gravitational pull causes the star to wobble. When the star moves away from the Earth, its spectrum redshifts; that is, it moves towards longer wavelengths. Similarly, starlight is shifted towards shorter, bluer, wavelengths when the star moves towards Earth.

    Astronomers take advantage of this effect to measure the changes in a star’s velocity due to an orbiting exoplanet — with astounding accuracy. HARPS can detect changes in the star’s velocity as small as 3.5 km/h — about walking pace. This approach to exoplanet hunting is known as the radial velocity method, and has never before been used to detect a similar super-Earth type exoplanet in such a large orbit around its star.

    “We used observations from seven different instruments, spanning 20 years of measurements, making this one of the largest and most extensive datasets ever used for precise radial velocity studies.” explained Ribas. ”The combination of all data led to a total of 771 measurements — a huge amount of information!”

    “We have all worked very hard on this breakthrough,” concluded Anglada-Escudé. “This discovery is the result of a large collaboration organised in the context of the Red Dots project, that included contributions from teams all over the world.

    Follow-up observations are already underway at different observatories worldwide.”

    Notes

    In 2016, astronomers using ESO telescopes and other facilities found clear evidence of a planet orbiting the closest star to Earth in this system, Proxima Centauri. That planet lies just over 4 light-years from Earth, and was discovered by a team led by Guillem Anglada Escudé.

    [2] The total velocity of Barnard’s Star with respect to the Sun is about 500 000 km/h. Despite this blistering pace, it is not the fastest known star. What makes the star’s motion noteworthy is how fast it appears to move across the night sky as seen from the Earth, known as its apparent motion. Barnard’s Star travels a distance equivalent to the Moon’s diameter across the sky every 180 years — while this may not seem like much, it is by far the fastest apparent motion of any star.
