ESO analysis confirms that the INNA industrial megaproject would have a devastating and irreversible impact on the facilities at Paranal Observatory in #Chile.
Light #pollution would increase by at least 35% above ESO's Very Large Telescope, by a minimum of 5% above ESO’s Extremely Large Telescope and by at least 55% above the south site of the Cherenkov Telescope Array Observatory
Air turbulence would also increase, degrading seeing conditions by up to 40%
Vibrations from the project could seriously impair the functioning of the ELT and the VLT Interferometer, which are both extremely sensitive to micro-seismic noise.
Dust during construction is also problematic as it settles on the telescope mirrors and obstructs their view.
