VLT, led by researchers in Portugal, shows the star cluster RCW 38 in all its glory. Credit: ESO/K. Muzic</small></p> <p>Portugal joined ESO as a Member State on 7 May 2001. The country’s community of scientists and engineers has contributed to many ESO projects in key ways, such as conducting research using ESO infrastructure, development of advanced instrumentation and telescopes, training of scientists, engineers and communicators, and with contracts awarded to Portuguese industry.&nbsp;&nbsp;</p> <p>Portugal currently contributes 1.19% of ESO’s annual revenue, with a value of 2 285 000 EUR.&nbsp;</p> <p>As of mid 2022, there are 10 Portuguese employees at ESO, nine in Germany and one in Chile. Furthermore, ESO has awarded six studentships,11 fellowships, and eight internships to Portuguese nationals since 2004.&nbsp;</p> <p>Portugal is represented in the various ESO governing and advisory bodies by astronomers and policy experts; the current Portuguese representatives of ESO’s various committees with national representation can be found <a href="https://www.eso.org/public/about-eso/committees.html" target="_blank" rel="noreferrer noopener">here</a>.&nbsp;</p> <p>The ESO Science Outreach Network (ESON) includes Portuguese <a href="https://www.eso.org/public/outreach/partnerships/eson/" target="_blank" rel="noreferrer noopener">representatives</a> who act as ESO’s media and outreach local contacts.&nbsp;</p> <p>Here follows some information about Portugal’s involvement with ESO.&nbsp;</p> <h2>Discoveries by Portugal-based astronomers using ESO telescopes&nbsp;</h2> <p>Portuguese researchers and those based at Portuguese institutions have been involved in important discoveries using ESO facilities, including many of the <a href="https://www.eso.org/public/science/top10/" target="_blank" rel="noreferrer noopener">ESO top 10 discoveries</a>. Scientific discoveries from the past few years include&nbsp;</p> <ul> <li>A study led by João Faria, a researcher at the Instituto de Astrofísica e Ciências do Espaço (IA/UPorto), and including many more Portuguese researchers from various institutions, a team discovered <a style="background-color: #ffffff;" href="https://www.eso.org/public/news/eso2202/" target="_blank" rel="noreferrer noopener">a new planet around Proxima Centauri</a>, the closest star to the Sun. Using one of ESO’s foremost planet hunters, <a style="background-color: #ffffff;" href="https://www.eso.org/public/teles-instr/paranal-observatory/vlt/vlt-instr/espresso/" target="_blank" rel="noreferrer noopener">ESPRESSO</a> on ESO’s <a style="background-color: #ffffff;" href="https://www.eso.org/public/teles-instr/paranal-observatory/vlt/" target="_blank" rel="noreferrer noopener">Very Large Telescope</a> (VLT), they could detect the signal of the planet, a thrilling discovery.&nbsp;</li> <li>Another recent, key exoplanet discovery which was led by researchers in Portugal was the <a href="https://www.eso.org/public/news/eso2112/" target="_blank" rel="noreferrer noopener">finding of a warm terrestrial planet with half the mass of Venus orbiting a nearby star</a>. Olivier D. S. Demangeon of the IA/UPorto, Centro de Astrofísica da Universidade do Porto [CAUP], Portugal and Departamento de Física e Astronomia, Faculdade de Ciências, Universidade do Porto) led the study.</li> <li>Portuguese researchers, including Susana Barros (IA/UPorto), Alexandre Correia (University of Coimbra) and Nuno Santos (IA/UPorto) were part of the team who discovered and studied a <a href="https://www.eso.org/public/news/eso2102/">puzzling six-exoplanet system</a> with the help of ESO’s VLT.</li> <li>Key discoveries related to the black hole at the centre of our galaxy by António Amorim (CENTRA, University of Lisbon) and Paulo Garcia, a researcher at Portugal’s Centre for Astrophysics and Gravitation (CENTRA) and the University of Porto, who are both members of the GRAVITY collaboration. Recent results include finding that a star moving close to a black hole follows an orbit that is <a href="https://www.eso.org/public/news/eso2006/" target="_blank" rel="noreferrer noopener">exactly as predicted</a> by Einstein’s Theory of General Relativity, and <a href="https://www.eso.org/public/news/eso2119/" target="_blank" rel="noreferrer noopener">making the most precise measurement yet of the black hole’s mass by tracking the orbits of stars</a> at the centre of our Milky Way.</li> <li>Using the <a href="https://www.eso.org/public/teles-instr/paranal-observatory/vlt/vlt-instr/hawk-i/" target="_blank" rel="noreferrer noopener">HAWK-I</a> camera on the VLT, a team of astronomers led by Koraljka Muzic (CENTRA, University of Lisbon) and Joana Ascenso (then at CENTRA &amp; University of Porto) obtained one of <a href="https://www.eso.org/public/news/eso1823/" target="_blank" rel="noreferrer noopener">the most stunning images ever</a> of the star cluster RCW 38. As seen in the image at the top of this page, the clouds of the cluster glow in exquisite detail, with dark tendrils of dust threading through the bright core of this young gathering of stars.</li> <li>David Sobral from the University of Lisbon, and Leiden Observatory in the Netherlands, who led a team of astronomers that discovered the brightest galaxy found in the young Universe, with strong evidence that <a href="https://www.eso.org/public/news/eso1524/" target="_blank" rel="noreferrer noopener">the first generation of stars</a> lurks within it.&nbsp;&nbsp;</li> </ul> <h2>Portuguese involvement in ESO instruments and telescopes at ESO sites&nbsp;</h2> <p>Portugal is contributing to many aspects of ESO, with Portuguese institutions behind already existing and upcoming instruments based at telescopes on ESO sites. These include:&nbsp;</p> <ul> <li><a href="https://www.eso.org/public/teles-instr/paranal-observatory/vlt/vlt-instr/espresso/" target="_blank" rel="noreferrer noopener">ESPRESSO</a>, a high-resolution spectrograph on the VLT, with the main scientific aim of detecting and characterising Earth twins in the habitable zone of solar-like stars. The universities of Porto and Lisbon are part of the consortium.&nbsp;</li> <li><a href="https://www.eso.org/public/teles-instr/paranal-observatory/vlt/vlt-instr/gravity/" target="_blank" rel="noreferrer noopener">GRAVITY</a>, a K-band beam combiner and spectrograph on the VLTI, with the main scientific aim of characterising the Galactic Centre supermassive black hole.
