19 Dicembre 2022: Forty-eight days after suspending observations due to a cyberattack, the Atacama Large Millimeter/submillimeter Array (ALMA) is observing the sky again. The computing staff has worked diligently to rebuild the affected observatory’s computer system servers and services. This is a crucial milestone in the recovery process. On 29 October, ALMA suffered a cyberattack. The computing staff took immediate countermeasures to avoid loss and damage to scientific data and IT infrastructure. The attack affected various critical operational servers and computers. “The challenge was to securely restore all the communication and computer systems as quickly as possible. We established an aggressive plan that required coordination with the ALMA partnership worldwide,” explains Jorge Ibsen, Head of the ALMA Computing Department. “Thanks to the active engagement of everyone in the collaboration, especially the Computing, Engineering, and Science Operations staff, and the cybersecurity experts from ESO, NAOJ, and NRAO, we managed to be observing as planned.” ...

23 Novembre 2022: ESO’s newest scientific instrument, the Enhanced Resolution Imager and Spectrograph (ERIS) has successfully completed its first test observations. One of them exposed the heart of the galaxy NGC 1097 in mesmerising detail. Installed on ESO’s Very Large Telescope (VLT) at Cerro Paranal in northern Chile, this infrared instrument will be able to see further and in finer detail, leading the way in Solar System, exoplanet and galaxy observations. The versatility of ERIS [1] will lend itself to many fields of astronomical research as it aims to take the sharpest images obtained to date using a single 8.2-metre telescope. It will do so using adaptive optics, a technique that corrects for the blurring effects of Earth’s atmosphere in real time. ERIS will be active for at least ten years and is expected to make significant contributions to a myriad of topics in astronomy, ranging from distant galaxies and black holes through ...

02 Novembre 2022: Update (18 Nov 2022) This event is under investigation by local authorities. The Computing team quickly isolated the Antennas and Correlator systems and the Science Archive data systems. However, communication and other operational clusters were affected, forcing ALMA to stop all observations. Since then, email communication has been restored safely, along with new collaboration tools that enable the staff to continue their regular work. The Crisis Management Team has developed a full-recovery plan in consultation with cyber security officers from ESO/NAOJ/NRAO. Our highest priority is to work hard to resume observations before the end of the year. Last Saturday, 29 October, at 6:14 AM (GMT-3), the ALMA observatory in Chile suffered a cyberattack on its computer systems, forcing the suspension of astronomical observations and the public website. There are limited email services at the observatory. The threat has been contained, and our specialists are working hard to restore affected systems. ...

26 Ottobre 2022: Leiden University has recently announced that a professor at the university has been found by the university’s Complaints Committee to have subjected colleagues to intimidating and unacceptable behaviour, including harassment.

12 Luglio 2022: After nine months of work, ESO and the Saesa Group inaugurated the Paranal-Armazones photovoltaic plant, which will supply renewable energy to ESO's Paranal Observatory and, soon, to the construction and operation of ESO's Extremely Large Telescope (ELT), the largest optical telescope in the world. After its inauguration, the plant became the largest solar complex in Chile supplying renewable energy to an astronomical observatory. With 18 565 panels, distributed over 7.2 hectares of land, it will harvest 9 megawatts of electric power. This will make it possible to cover 100% of the energy needed to operate ESO’s facilities, such as the Very Large Telescope and the ELT, during a day, the period with the greatest energy demand due to the telescopes’ cooling systems. “This milestone is a dream that becomes reality! Today we are closing an endeavour that started more than ten years ago, when the Chilean Ministry of Energy together ...

27 Giugno 2022: The Near InfraRed Planet Searcher (NIRPS) instrument, mounted on ESO’s 3.6-m telescope at the La Silla Observatory in Chile, has successfully performed its first observations. Its mission is to search for new exoplanets around the Milky Way’s coolest stars. “NIRPS has been a long time in the making, and I’m thrilled with how this mission has come together!” says René Doyon, Director of the Institute for Research on Exoplanets, Université de Montréal, and co-Principal Investigator of NIRPS. “This incredible infrared instrument will help us find the closest habitable worlds to our own Solar System.” The instrument will focus its search on rocky worlds, which are key targets for understanding how planets form and evolve, and are the most likely planets where life may develop. NIRPS will search for these rocky exoplanets around small, cool red dwarf stars — the most common type of stars in our Milky Way galaxy, which ...

20 Maggio 2022: ESO’s observatory sites in Chile are once again opening their doors to the public, after two years of pandemic-related closures.

11 Marzo 2022: Due to the war in Ukraine, to support our colleagues in the scientific community and their families, ESO is announcing a Special Visitor Programme for Scientists working in the country to visit one of the ESO premises (Garching, Germany or Vitacura, Chile) to conduct scientific or technical projects. Grants will be provided in support of these scientific visits, and travel and accommodation will be covered for the full duration of the project. More information can be found on the ESO science pages. All ESO Member States have condemned the military invasion of Ukraine ordered by the Russian leadership, which blatantly violates the most fundamental human rights and is entirely incompatible with our values at ESO. ESO does not have and does not intend to have any official relationship with institutions and companies from Russia and Belarus under the current circumstances.

24 Febbraio 2022: Last year proved to be a record-breaking year for research based on observations conducted at ESO observatories. A recent report by the ESO Library and Information Centre shows that, in 2021 alone, over 1100 papers including ESO data were released, the highest annual number of publications from ESO telescope data to date. The most significant contribution to these publications comes from ESO’s Very Large Telescope (VLT), and the VLT Interferometer (VLTI), which yielded data included in over 600 studies. The Multi Unit Spectroscopic Explorer (MUSE) continues to be one of the most productive VLT instruments, providing data for over 160 articles in 2021. There has also been a steep increase in papers using data from the VLTI instrument GRAVITY this year. Highlights from these facilities include the discovery, using MUSE, of the closest pair of supermassive black holes to date and investigations into the causes of Betelgeuse’s great dimming, which ...

11 Febbraio 2022: Today marks the United Nations’ International Day of Women and Girls in Science. The day aims to promote equal access to science for women and girls, serving as a reminder that they play a critical role in science and technology communities, and that their participation in them should be promoted. ESO has taken important steps towards diversity and inclusion of all genders, including over the past year, and will be hosting a week of activities to celebrate this day. In October 2021, as part of the agreement between ESO and UN Women signed in 2020, ESO started participating in the Second Chance programme (Tu Oportunidad) in Chile. In partnership with UN Women, ESO began to train seven Chile-based women in key astronomical technical skills, such as the coating of large telescope mirrors, which will allow them to expand their job opportunities and gain the skills to work in top astronomical ...

10 Febbraio 2022: On 9 February, ESO and Australia signed an amendment to broaden the scope of their strategic partnership. By virtue of this expanded agreement, Australia will join ESO’s Technology Development Programme, meaning Australian companies and institutions will be eligible to work with ESO in developing future technologies for ground-based telescopes. Australia has been a Strategic Partner of ESO since 2017. The partnership has granted Australian astronomers and industry access to ESO’s state-of-the-art research infrastructure at the La Silla and Paranal observatories, including telescopes such as ESO’s Very Large Telescope or ESO’s 3.6m Telescope [1]. They also have the opportunity to collaborate with ESO Member State institutions on developing instruments for these observatories. The amendment signed today will further strengthen this partnership by allowing Australia to participate in ESO’s Technology Development Programme. Launched in 2014, this programme brings ESO’s engineers and industry together to develop future technologies for ground-based astronomy in areas ...

07 Febbraio 2022: Una collaborazione internazionale che coinvolge l'ESO ha presentato un nuovo documento al Comitato delle Nazioni Unite per gli usi pacifici dello spazio esterno (COPUOS) alla ricerca di una migliore protezione dei cieli bui e quieti della Terra. Il documento è stato accettato per la discussione oggi durante la sessione in corso della sottocommissione scientifica e tecnica del COPUOS, segnando la prima volta in cui il problema del cielo buio e quieto è stato presentato formalmente all'ordine del giorno dalle Nazioni Unite. Il documento, che è stato approvato da Cile, Spagna e Slovacchia, incoraggia la comunità internazionale a proteggere le capacità di osservazione astronomica globale da interferenze artificiali dannose e dirompenti. Il cielo notturno offre al fortunato spettatore un ricco arazzo di stelle, ma negli ultimi decenni la sua qualità è diminuita a causa dell'aumento incontrolato dell'inquinamento luminoso a terra. Ora sta emergendo una nuova minaccia: il gran numero di satelliti ...
