Plans for the world’s largest telescope just took a major step forward. Researchers have selected a site for the European Extremely Large Telescope (E-ELT): It will sit on the Cerro Armazones mountain in central Chile’s Atacama Desert. This site beat out other contenders, including other sites in Chile and La Palma in Spain, due to its excellent conditions for astronomy.<\/p>\n
On this desert mountain, researchers will enjoy near-perfect observing conditions – at least 320 nights a year when the sky is cloudless. The Atacama’s famous aridity means the amount of water vapour in the atmosphere is very limited, reducing further the perturbation starlight experiences as it passes through the Earth’s atmosphere [BBC<\/a>].<\/span> With such clear skies, astronomer Diego Mardones from the University of Chile remarked, \u201cIf you want to find another [observation area] like Chile, your options are Antarctica or space\u201d [Merco Press<\/a>].<\/span><\/p>\n The telescope’s primary mirror will measure 138 in diameter. The mirror will be made up of 984 segments and will gather 15 times more light than the largest optical telescope\u00a0while\u00a0returning images 15 times sharper than those beamed back\u00a0from the Hubble Space Telescope [Wired<\/em><\/a>]<\/span>. Astronomers say the telescope will provide new information on the nature of black holes, galaxy formation, dark matter, and dark energy.<\/p>\n The E-ELT, which is estimated to cost almost a billion euros, is expected to be operational by 2018. The final go-ahead for the telescope’s construction is expected later this year.<\/p>\n Related Content: Plans for the world’s largest telescope just took a major step forward.
