A group of international astronomers urged Chilean officials this week to reconsider a large renewable-energy project planned near the Paranal Observatory in the Atacama Desert, one of the world’s most valuable locations for space research. Scientists stated that the project could interrupt the stable darkness that allows telescopes to capture clear images of planets, stars, and distant galaxies. They noted that strong winds, new lighting, and additional movement around the site may create conditions that weaken astronomical observations. The warning followed an open letter signed by several leading researchers who explained that the Atacama’s rare environment makes it extremely important for global studies of the universe.

Officials said the energy project is still undergoing environmental review and includes wind farms, solar fields, and hydrogen-fuel facilities. Astronomers explained that these changes may reduce visibility and produce new vibrations that travel through the ground. They added that light pollution could rise more than 30%, which may limit the performance of sensitive telescopes. Experts also described the dispute as part of a larger global issue, as many dark-sky regions face pressure from industrial growth. Astronomy groups argued that protecting these areas is essential because only a few locations on Earth can provide the clarity needed for high-level research. They warned that losing the Atacama’s natural darkness would affect the scientific progress of many countries that rely on data collected in Chile.
