Mirror mirror on the wall... err, sorry: on ESO's Extremely Large Telescope! The first segments of the primary mirror of the ELT now have a shiny layer of protected silver.
Once fully assembled, the primary mirror will be 39 m wide. It will consist of 798 of these hexagonal segments, working together as a single mirror thanks to a complex system of sensors and positioning actuators with nanometric accuracy.
