ESO and Chile sign agreement on E-ELT
The European Extremely Large Telescope (E-ELT), with its 40-metre-class primary mirror, has been dubbed the world's biggest eye on the sky. In March 2010, the mountain Cerro Armazones in the region of Antofagasta in Chile was selected by ESO (http://www.eso.org/public/announcements/ann1013/) as the future site for the E-ELT. The new telescope will be integrated into the Paranal Observatory, already comprising the Very Large Telescope (VLT), the VLT interferometer and the Survey Telescopes. Cerro Paranal is only 20 kilometres from Cerro Armazones and much of the infrastructure can be shared between the two sites.
This agreement represents another significant contribution to the scientific and technological cooperation between Chile and ESO, which began in 1963 with the signature of the first agreement. ESO and Chile have cooperated in many joint astronomy-related projects in instrumentation and technology, as well as the training of scientists, engineers and technicians, with the goal of further developing astronomical competence and awareness in Chile, which is one of the world's leading astronomical regions.
"This agreement makes it possible to construct the E-ELT as part of the VLT system. It also greatly increases our involvement and cooperation with Chilean society and will open up further possibilities for great discoveries and technological progress," said Tim de Zeeuw, Director General of ESO.
The agreement includes the donation of 189 km2 of land around Cerro Armazones for the installation of the E-ELT as well as a concession for 50 years relating to the surrounding area, representing an additional 362 km2 , which will protect the E-ELT from light pollution and mining operations. With the current 719 km2 of land around Cerro Paranal the total protected area around the Paranal-Armazones complex will thus reach 1270 km2 .
The Chilean Minister of Foreign Affairs Alfredo Moreno said: "Chile has the clearest skies on Earth and hosts the most important centres for astronomical observation. It is part of our assets and also part of our contribution to humanity. The presence of ESO and the E-ELT project in our country are an important demonstration of the interest of Chile in promoting technology and science".
The Chilean government also expressed its commitment to provide infrastructure support, such as maintaining the road system connecting the observatories to Antofagasta, assistance in connecting the Paranal Observatory to the national power grid, as well as assistance in studying possible renewable power supply solutions.
In exchange, ESO extends the agreed 10% share of observing time for proposals from Chilean astronomers to the E-ELT. At least three quarter of these proposals will be allocated to Chilean astronomers cooperating with astronomers from ESO Member States. This will help foster international collaborations — a fundamental ingredient in a mega-science project of this dimension.
The E-ELT is ESO's most ambitious project so far. With the start of operations planned for early in the next decade, the E-ELT will tackle the biggest scientific challenges of our time, and aim for a number of notable firsts, including tracking down Earth-like planets around other stars in the "habitable zones" where life could exist.
