Southern Observatory (ESO) has become a partner in a new project, launched last week, that has formed Europe’s largest ground-based astronomy network — the Opticon-RadioNet Pilot (ORP). This network fosters the collaboration of 37 institutions, including ESO, from Europe, Australia and South Africa. Within the ORP, ESO will drive knowledge transfer by organising a broad suite of training programmes for the European astronomy community, which will include observing schools across European observatories, as well as archival, instrumentation, and proposal writing workshops. In the long term, ESO will also help the ORP develop strategies to promote equal-opportunity policies and actions in the astronomy community. With 15 million EUR of funding from the European Union’s Horizon 2020 research and innovation programme, the ORP merges two existing astronomy networks (Opticon and RadioNet) to bring together several telescopes and arrays from around the world, providing European astronomers access to a wide range ...</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/web/20210512093034/https://www.eso.org/public/announcements/ann21004/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210512093034im_/https://cdn.eso.org/images/thumb350x/ann21004a.jpg"> </div> <div class="news-description"> <div class="news-id">ann21004 — Announcement</div> <div class="news-title">The Messenger No. 182 Now Available</div> <div class="news-teaser"><strong>2 March 2021</strong>: The latest edition of ESO's journal, The Messenger, is now available online. This is a special issue dedicated to the instrumentation programme for ESO’s Extremely Large Telescope (ELT). Selecting instruments for any telescope is a crucial step, making sure that the astronomical community it serves can undertake the scientific projects for which the telescope was designed. ESO has been working with its community of astronomers and instrument builders to establish the sequence in which the instruments planned for the ELT will be built and delivered to the observatory. This edition of The Messenger provides a status overview of the ELT instrumentation programme.

The new and improved CRIRES+, which has now seen first light, will develop the work of its predecessor and search for potentially habitable super-Earth exoplanets. CRIRES+, an instrument built by ESO in collaboration with a consortium of European institutes, will search the sky for super-Earths located within the habitable zones of nearby low-mass stars, the range of planetary orbits within which scientists believe a planet can support life. These types of planets are difficult to detect due to their relatively low masses. With CRIRES+, scientists will be better equipped to search for these super-Earths as they will be able to survey most stars in our stellar neighbourhood. Other science goals of CRIRES+ include studying the atmosphere of transiting exoplanets and the origin and evolution of ...</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/web/20210512093034/https://www.eso.org/public/announcements/ann21002/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210512093034im_/https://cdn.eso.org/images/thumb350x/ann21002a.jpg"> </div> <div class="news-description"> <div class="news-id">ann21002 — Announcement</div> <div class="news-title">How ESO Impacts Society: New publication highlights ESO’s benefits to its Member States</div> <div class="news-teaser"><strong>22 January 2021</strong>: The European Southern Observatory (ESO) is a testament to research, innovation, and collaboration in Europe with a far reaching and invaluable impact on society. The new publication “ESO’s Benefits to Society” explores ESO’s contributions to its Member States across five areas: science and engineering, economy and innovation, talent development, education and outreach, and international collaboration and policy. In science and engineering, ESO and its telescopes have been instrumental in several ground-breaking discoveries. In 2020, for example, a Physics Nobel Prize was awarded for research on the Milky Way’s black hole done with ESO telescopes. ESO enables discoveries such as this by constructing and operating world-leading observatories, which push the boundaries of engineering.

The report concludes that large constellations of bright satellites in low Earth orbit will fundamentally change ground-based optical and infrared astronomy and could impact the appearance of the night sky for stargazers worldwide. It also offers a roadmap for observatories and satellite operators to work together to lessen these impacts. The report offers two main findings. First, low-Earth-orbiting satellites disproportionately affect science programmes that require twilight observations, such as searches for Earth-threatening asteroids or for the visible-light counterparts of fleeting gravitational-wave sources. Satellites orbiting below 600 kilometres have limited interference with astronomical observations during the night’s darkest hours.
