La Silla Observatory
La Silla Observatory is an astronomical observatory in Chile with three telescopes built and operated by the European Southern Observatory (ESO). Several other telescopes are also located at the site and are partly maintained by ESO. The observatory is one of the largest in the Southern Hemisphere and was the first in Chile to be used by ESO. The La Silla telescopes and instruments are located in the North of the Coquimbo region, 150 km northeast of La Serena, on the outskirts of the Atacama Desert, one of the driest and most remote areas in the world.
