Paper day! REASONS ALMA and SMA survey results: the largest sample of 74 resolved exocomet belts revealing the structure and evolution of extrasolar Kuiper-belt analogs, the ice reservoirs of planetary systems! 🧊 See @eso.org blog below, paper here: tinyurl.com/reas25 + associated press releases! 🔭

The Kuiper Belt contains the frozen leftovers of the formation of our Solar System. Using ALMA astronomers can observe similar belts around other stars, and they come in all shapes and sizes! What do they tell us about the formation of planetary systems? Find out: ➡️ www.eso.org/public/blog/... 🔭 🧪

The skies above Paranal are at risk from a proposed industrial megaproject.  This would be located in the vicinity of ESO's Observatory. If constructed, it would irreparably impact astronomical observations. Read more: https://www.eso.org/public/news/eso2501/ 🔭  📷 ESO/P. Horálek

World's darkest and clearest skies at risk from industrial megaproject

On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical observatory in the world [1]. The industrial megaproject is planned to be located just 5 to 11 kilometres from telescopes at Paranal, which would cause irreparable damage to astronomical observations, in particular due to light pollution emitted throughout the project’s operational life. Relocating the complex would save one of Earth's last truly pristine dark skies.
