E-ELT (European Extremely Large Telescope)

The E-ELT (European Extremely Large Telescope) project aims to provide European astronomers with the largest optical-infrared telescope in the world. With a diameter of 40m and incorporating a large deformable mirror, the E-ELT is expected to 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. It will also perform “stellar archaeology” in nearby galaxies, as well as make fundamental contributions to cosmology by measuring the properties of the first stars and galaxies and probing the nature of dark matter and dark energy.

The telescope will gather 15 times more light than the largest optical telescopes operating today. The telescope has an innovative five-mirror design that includes advanced adaptive optics to correct for the turbulent atmosphere, giving exceptional image quality. The main mirror will be made up from almost 1000 hexagonal segments.

ESO To Build World’s Biggest Eye On The Sky

June 13, 2012 Leave a comment

ESO is to build the largest optical/infrared telescope in the world. At its meeting in Garching today, the ESO Council approved the European Extremely Large Telescope (E-ELT) Programme, pending confirmation of four so-called ad referendum [1] votes. The E-ELT will start operations early in the next decade.

ESO’s governing body, the Council, met today, at the ESO Headquarters in Garching, Germany. The main topic on the agenda was the start of the European Extremely Large Telescope (E-ELT) Programme — the world’s biggest eye on the sky. The E-ELT will be a 39.3-metre segmented-mirror telescope sited on Cerro Armazones in northern Chile, close to ESO’s Paranal Observatory.

All of ESO’s Member States have already expressed very strong support for the E-ELT project (see eso1150). The Council has today voted in favour of a resolution for the approval of the E-ELT and its first suite of powerful instruments, pending confirmation of the so-called ad referendum votes.

To approve the start of the programme, two-thirds of the Member States (at least ten) had to vote in favour. At the Council meeting Austria, the Czech Republic, Germany, the Netherlands, Sweden and Switzerland voted in favour of the start of the E-ELT programme. Four further countries voted in favour ad referendum: Belgium, Finland, Italy, and the United Kingdom. The remaining four Member States are actively working towards joining the programme in the near future.

The governing body of the European Southern Observatory, the ESO Council, has approved ESO’s budget for 2012. This includes preparatory work on the road to the European Extremely Large Telescope (E-ELT) site at Cerro Armazones and the start of development of some very challenging optical components for the telescope. With several ESO Member States now having committed their part of the required additional funding, the final approval for the whole E-ELT programme is expected in mid-2012.

At its 124th meeting, at ESO’s headquarters, on 7–8 December 2011 the ESO Council approved the budget for 2012, which contains funding for some of the first elements of the E-ELT. These include the preparatory work on the access roads to the telescope site on Cerro Armazones and the start of work on the challenging adaptive optics mirror (M4 — i.e. the fourth mirror out of five in the telescope). Work will start in early 2012. Final approval of the whole E-ELT project by Council is expected in mid-2012.
