E-ELT - European Extremely Large Telescope

400 years ago, Galileo Galilei built the first 37-mm lens telescope and went down in history thanks to his discoveries in the astronomical field. Nowadays, both the Italian and the European industries are working together to design the greatest telescope of all times: ELT – Extremely Large Telescope by ESO – European Southern Observatory; which will have a 39m diameter primary mirror.

EIE has been working beside ESO since 2007 in the study and the definition of the biggest telescope of the world. We developed Feasibility studies, Conceptual Design studies for the telescope as well as FEED (Front End Engineering Design) studies for the characterisation of the Dome and Telescope Main Structure; initially for a 42m diameter primary mirror telescope and subsequently for the final version, a 39m diameter telescope. Seven years later, in 2014, ESO opened the invitation to tender for the “Design, Manufacture, Transport, Construction, On-Site Assembly and Verification of the Dome and Main Structure of the European Extremely Large Telescope".

Last February 5th 2016, ESO’s Financial Committee authorized ESO to enter into final discussion with the ACe Consortium, consisting of the industrial companies Astaldi SpA, Cimolai Spa, with EIE GROUP as nominated sub-contractor, the winning bidder, at the end of an extraordinary session, last February 3rd, with the aim of contract signature in May 2016.

ELT will be a revolutionary optical instrument for medium and near infrared observations; the 39m diameter primary mirror will gather up to 13 times more light than the large optical telescopes operating today and it will give images 16 times more clearer than those obtained from the space telescope Hubble. ELT will definitely be the most powerful telescope in the world, equipped with ground-breaking technologies and innovative systems.
The ELT telescope is an extraordinary scientific and technology challenge that will revolutionize our perception of the Universe, as Galileo Galilei’s telescope did 400 years ago.

ELT will be installed in Chile, on the Cerro Armazones, in the central part of the Atacama Desert, 130 km south of Antofagasta, at 3.046 m on the sea level.

The ELT telescope represents an extraordinary set of scientific and technological challenges. In order to have a perception of its greatness, just think that the telescope will be 65m high and will weigh 3500t (including mechanisms), with a 39m in diameter primary mirror made of 798 hexagonal segments of 1.4m in diameter and a thickness of 5 cm. The rotating dome will be 95 m in diameter, 80 m high and will weigh around 4980 t (excluding auxiliary buildings and civil works).

La Scienza con EELT

I telescopi giganti sono considerati, in tutto il mondo, una delle più alte priorità dell’Astronomia da terra contemporanea. E-ELT, col suo occhio da 39m di diametro, rivoluzionerà la nostra percezione dell’Universo, raccogliendo fino a 15 volte più luce rispetto ai più avanzati strumenti ottici oggi attivi. Il telescopio, presenta un innovativo design a 5 specchi e include ottiche adattive in grado di correggere le deformazioni dell’atmosfera, garantendo eccezionale qualità d’immagine.
Con E-ELT la scienza sarà in grado di studiare i pianeti extra-solari, dai dischi protoplanetari attorno a stelle in formazione, fino allo studio delle atmosfere di pianeti già formati, con la possibilità di scoprire se c’è vita su di essi.
E-ELT consentirà di dare risposta a quesiti che da sempre l’uomo si pone circa la formazione dei pianeti e la loro evoluzione. Inoltre sarà possibile studiare le prime galassie seguendone l’evoluzione attraverso il tempo cosmico.
E-ELT sarà uno strumento unico attraverso il quale si potrà creare un inventario degli elementi dell’Universo in continua evoluzione, capire la storia della formazione delle stelle nelle galassie.
