First segments of the world's largest telescope mirror shipped to Chile

The construction of the European Southern Observatory's Extremely Large Telescope (ESO's ELT) has reached an important milestone with the delivery to ESO and shipment to Chile of the first 18 segments of the telescope's main mirror (M1). Once they arrive in Chile, the segments will be transported to the ELT Technical Facility at ESO's Paranal Observatory in the country's Atacama Desert, where they will be coated in preparation for their future installation on the telescope's main structure.
