We have reached the top!
The protective dome of our Extremely Large Telescope (ELT) will have two giant sliding doors, that will open at night to allow the ELT to gaze up at the cosmos.
Their structure is being installed atop the dome, meaning that the ELT has reached its highest point. We recently celebrated this symbolic milestone in a ceremony, known as “Tijerales” in #Chile, raising the ESO and Chilean flags.
