Mount Paranal, perched at 2,600 meters above sea level in the Atacama Desert, is a haven for astronomers.Shielded by the Andes Mountains and located 120 kilometers from the nearest city, it offers unparalleled conditions for stargazing.The site hosts the Very Large Telescope (VLT) and the under-construction Extremely Large Telescope (ELT), both of which rely on the region’s pristine skies for groundbreaking discoveries.
“It is indeed not without reason that this place is plunged into darkness,” notes the original report. The VLT, for instance, has been instrumental in capturing the first image of an exoplanet in 2004 and contributed to Nobel Prize-winning research in 2011 and 2020.
The Threat of Light Pollution
The INNA project’s potential impact on the observatory’s operations cannot be overstated.Light pollution from the industrial complex could disrupt the delicate balance of darkness that makes Paranal a global hub for astronomy. “What worries astronomers even more is its location: between 5 and 12 kilometers from the purest sky in the world,” the report emphasizes.
The stakes are high. The VLT and ELT are not just scientific instruments; they are windows to the universe, enabling discoveries that reshape our understanding of space. The ELT, in particular, is designed to push the boundaries of astronomy, offering insights into the formation of galaxies and the search for extraterrestrial life.
A Clash of Priorities
The conflict between industrial progress and scientific preservation is not new, but the scale of this project makes it especially contentious.While AES Andes has submitted an Environmental Impact Assessment, astronomers warn that the project could irreversibly damage one of the last untouched skies on Earth.
