1 00:00:07,960 --> 00:00:11,840 Building the Biggest Optical Telescope in the World 2 00:00:13,220 --> 00:00:20,960 Construction is underway at Cerro Armazones — the future home of the Extremely Large Telescope (ELT). 3 00:00:22,720 --> 00:00:31,740 When construction is done the ELT will be the largest optical telescope ever built — a dome the size of a cathedral. 4 00:00:32,980 --> 00:00:39,900 It will dwarf all existing optical telescopes and usher in a new era of ground-based astronomy. 5 00:00:42,300 --> 00:00:53,920 With the ELT, we will search for signs of life on distant worlds, study the nature of dark energy and dark matter, and explore the origins of the Universe. 6 00:00:55,140 --> 00:01:01,780 Once complete, the ELT will give us a view of the Universe that we cannot yet imagine. 7 00:01:06,780 --> 00:01:10,720 Transcribed by ESO; Translated by —
