Press ReleaseNew ESO analysis confirms severe damage from industrial complex planned near ParanalAn in-depth technical analysis by the European Southern Observatory (ESO) has evaluated the impact of the INNA megaproject on the facilities at the Paranal Observatory, Chile — and the results are alarming. In that case, our already alarming results would underestimate the potential impact of the INNA project on the Paranal sky brightness,” Kaufer explains. We are more committed than ever to working together to protect the irreplaceable Paranal skies,” concludes Barcons. At Paranal, ESO operates the Very Large Telescope and its Very Large Telescope Interferometer, as well as survey telescopes such as VISTA. Also at Paranal ESO will host and operate the Cherenkov Telescope Array South, the world’s largest and most sensitive gamma-ray observatory.
