A new study conducted by researchers from Italy, Chile, and Galicia reveals that light pollution is significantly affecting the skies above many of the world's major astronomical observatories. The study, published in Monthly Notices of the Royal Astronomical Society, emphasizes the urgent need for measures to reduce artificial light contamination to preserve the efficacy of ground-based astronomy. The research team examined light pollution levels at nearly 50 observatories globally, including both large professional facilities and smaller amateur observatories. Utilizing a model that simulates light propagation in the Earth's atmosphere and incorporating night-time satellite data, the study provides a comprehensive overview of the current state of light pollution at these sites.
