Extremely Large Telescope, Ground telescope in Cerro Armazones, Chile
The Extremely Large Telescope features a primary mirror measuring 39.3 meters in diameter, situated at an elevation of 3,046 meters in the Atacama Desert.
The European Southern Observatory initiated the telescope construction in 2014 after selecting Cerro Armazones as the optimal location due to its atmospheric conditions.
Scientists from multiple nations collaborate at this astronomical facility to study distant galaxies, exoplanets, and the fundamental properties of the universe.
The telescope structure includes 798 hexagonal mirror segments, advanced instruments for spectroscopy, and a rotating dome weighing over 5,000 metric tons.
The facility contains specialized adaptive optics technology that corrects atmospheric distortions, enabling observations with unprecedented clarity and precision.
