Chile: The largest optical telescope on the planet begins to build



Construction telescope The world's largest optical telescope, the Extreme Large Telescope (ELT) of the European Southern Observatory (ESO), has already begun and is expected to gather more light when it operates more than 200 space telescopes such as Hubble.

It is a telescope intended for acquiring the first images in 2024. Works began in the Chilean Andes, in the Atacama Desert, where the most powerful eyes are centered on the sky. It was not easy to find a suitable place for such a structure, the ESO confirmed today. In addition to the need for dry conditions and the absence of air pollution at high altitudes, necessary for the success of astronomical observations, a large space for the expansion of the bases is also needed.

When the ELT telescope is ready, it will weigh 3 tons, with a dome of 90 meters high, as high as a 30-story building and with a large base as a football field. Thus began the era of large new generations of telescopes, which promise to revolutionize the understanding of the universe. ELT will have a 39.3 meter diameter mirror, compared to 8.3 meters of the four telescopes that make up another great astronomer: the Large Telescope (VLT), always in the Atacama Desert and is always operated by THAT.

Because it is impossible to build a 39-meter mirror, the primary ELT mirror will consist of a complex structure of the 798 hexagonal mirror structure of 1.4 meters that perfectly fits between them. One of his main tasks will be to search for the possible depths of the earth and see the atmosphere to analyze it in search of elements of life.
