Birds eye view of the elaborate 3-dimensional model of the European Extremely Large Telescope developed to determine expected performance during observing conditions. With a 40-metre-class diameter primary mirror, the present baseline, its total rotating

A full-sized mock-up of the E-ELT primary mirror built by participants at ESOs Open House Day 2011.

Several test segments of the giant primary mirror of the E-ELT are currently undergoing testing close to ESO’s headquarters in Garching, Germany. This picture shows an engineer adjusting the complex support mechanisms that control the shape and posit

On 26 April 2010, the ESO Council selected Cerro Armazones as the site for the planned 40-metre-class European Extremely Large Telescope. Cerro Armazones is an isolated mountain at 3060 metres altitude in the central part of Chiles Atacama Desert, some 13
