An extremely large telescope (ELT) is an astronomical observatory featuring a telescope with an aperture for its primary mirror from 20 metres up to 100 metres across, when discussing reflecting telescopes of optical wavelengths including ultraviolet (UV), visible, and near infrared wavelengths. Among many planned capabilities, ELTs are planned to increase the chance of finding Earth-like planets around other stars. Telescopes for radio wavelengths can be much bigger physically, such as the 300 metres (330 yards) aperture fixed focus radio telescope of the Arecibo Observatory. Freely steerable radio telescopes with diameters up to 100 metres (110 yards) have been in operation since the 1970s.
These telescopes have a number of features in common, in particular the use of a segmented primary mirror (similar to the existing Keck telescopes), and the use of high-order adaptive optics systems. See also the List of largest optical reflecting telescopes for other large finished telescopes.
The European Extremely Large Telescope (E-ELT) is an astronomical observatory and the world's largest optical/near-infrared extremely large telescope now under construction. Part of the European Southern Observatory (ESO), it is located on top of Cerro Armazones in the Atacama Desert of northern Chile. The design comprises a reflecting telescope with a 39.3-metre-diameter segmented primary mirror and a 4.2-metre-diameter secondary mirror, and will be supported by adaptive optics, six laser guide star units and multiple large science instruments. The observatory aims to gather 13 times more light than the largest optical telescopes existing today, be able to correct for atmospheric distortions and provide images 16 times sharper than those from the Hubble Space Telescope.
The E-ELT is intended to vastly advance astrophysical knowledge by enabling detailed studies of planets around other stars, the first galaxies in the Universe, super-massive black holes, and the nature of the Universe's dark sector, and to detect water and organic molecules in protoplanetary disks around other stars. The facility is expected to take 11 years to construct.
Cerro Armazones is a mountain located in the Sierra Vicuña Mackenna of the Chilean Coast Range, approximately 130 km (81 mi) south-east of Antofagasta in the Antofagasta Region, Chile. Before the construction of the European Extremely Large Telescope started the summit was a horizontal control point with an elevation of 3,064 metres (10,052 ft). It is located in a privileged zone for optical astronomy because it has 89% cloudless nights a year. It currently hosts the 1.5 m (5 ft) Hexapod-Telescope and other telescopes at the Cerro Armazones Observatory.
On 26 April 2010, the European Southern Observatory Council selected Cerro Armazones as the site for the planned European Extremely Large Telescope.

The European Southern Observatory (ESO, formally: European Organisation for Astronomical Research in the Southern Hemisphere; French: Observatoire européen austral) is a 16-nation intergovernmental research organisation for astronomy. Created in 1962, ESO has provided astronomers with state-of-the-art research facilities and access to the southern sky. The organisation employs about 730 staff members and receives annual member state contributions of approximately €131 million. Its observatories are located in northern Chile.
ESO has built and operated some of the largest and most technologically advanced telescopes. These include the New Technology Telescope, an early pioneer in the use of active optics, and the Very Large Telescope (VLT), which consists of four individual telescopes, each with a primary mirror 8.2 metre across, and four smaller auxiliary telescopes. The Atacama Large Millimeter Array observes the universe in the millimetre and submillimetre wavelength ranges, and is the world's largest ground-based astronomy project to date. It was completed in March 2013 in an international collaboration by Europe (represented by ESO), North America, East Asia and Chile.
ESO has awarded the biggest contract in ground-based astronomy — to build the E-ELT dome and telescope structure. So it’s a good time to take a look at what the E-ELT will be. Credit: ESO.

The Atacama desert in Chile is famous for nothing: no water, no plants, no animals. That makes it a perfect place for astronomy, and the ideal location to build the European Extremely Large Telescope, or E-ELT, the world's largest ever optical and infrared telescope. The first stage of construction is destruction, namely blowing up the top of a mountain.

ESO’s 39-metre Extremely Large Telescope (ELT) will be the largest telescope of its kind ever built when it achieves first light in 2024. A new milestone has now been reached with the casting of the telescope’s secondary mirror (M2), which is larger than the primary mirror of many of today’s research telescopes. The mirror blank is the cast block of material — in this case Zerodur® glass-ceramic — that will then be ground and polished to produce the finished mirror. In January 2017, ESO awarded SCHOTT the contract to manufacture the M2 mirror blank. ESO has enjoyed a fruitful collaboration with SCHOTT, who also produced the 8.2-metre meniscus main mirrors for the Very Large Telescope at ESO’s Paranal Observatory. A manufacturer of exceptional astronomical products to a very high standard, ...

The European Extremely Large Telescope, or E-ELT for short, will be by far the largest optical and near-infrared telescope in the world. In early December 2014 the ESO Council gave the go-ahead for the first construction phase of the telescope.

A primeira pedra do Extremely Large Telescope do ESO (ELT) foi hoje colocada pela Presidente da República do Chile, Michelle Bachelet Jeria, durante uma cerimónia que decorreu no Cerro Armazones, 3046 metros acima do nível do mar, no norte do Chile perto do Observatório do Paranal do ESO. Este marco assinalou o início da construção da cúpula e da estrutura principal daquele que será o maior telescópio óptico do mundo e anunciou o despertar de uma nova era na astronomia. A cerimónia marcou também a ligação do observatório à rede eléctrica nacional chilena. A Presidente Bachelet foi recebida por Tim de Zeeuw, Diretor Geral do ESO, Roberto Tamai, Gestor de Programa do ELT, e Andreas Kaufer, Diretor do Observatório La Silla Paranal.

Die chilenische Atacamawüste ist bekannt für gar nichts: kein Wasser, keine Pflanzen, keine Tiere. Das macht es zum perfekten Ort für ein bahnbrechendes Projekt, für den Bau des E-ELT, das European Extremely Large Telescope. Zur Vorbereitung des Baus wurde ein Teil des Berggipfels des Cerro Armazones gesprengt, um ihn einzuebnen. "Wir sprengen die Spitze des Berges, um Platz für eine Konstruktion zu schaffen, die alles in den Schatten stellt, was wir bisher gebaut haben", so Rob Ivison von der ...

É lei la donna mia, é lei
che non potró lasciare mai
perché ora lo so
per l'eternitá il nostro amore durerá.
É lei la donna mia, é lei
e a tutto il mondo grideró
che tutta la mia vita, la mia felicitá
é lei, é lei, é lei . . .
To you, I give my heart completely,
To you, my love, forevermore,
All that I possess,
My life and nothin' less,
I offer humbly at your door!
To me, you bring a glimpse of heaven,
The world I really never knew,
And in return I'll give,
As long as I may live,
Devotion, only to you!
