The giant ELT dome will house the telescope and its interior structure, providing protection from the extreme environment of Chile’s Atacama Desert. The main structure of the telescope will hold its five mirrors and optics, including the enormous 39-metre primary mirror.

An extremely large telescope (ELT) is an astronomical observatory featuring an optical telescope with an aperture for its primary mirror from 20 metres up to 100 metres across, [1] [2] when discussing reflecting telescopes of optical wavelengths including ultraviolet (UV), visible, and near infrared wavelengths.
