La Silla Observatory
Coordinates: 29 ° 15 ′ 23 " S , 70 ° 44 ′ 17" W
The La Silla Observatory , located about 600 kilometers north of Santiago de Chile on the 2400 m high mountain La Silla in the municipality of La Higuera , was the first observatory of the European Southern Observatory (ESO) in Chile , to which another observatory has since opened the Cerro Paranal has been added. The asteroid (2187) La Silla was named after the mountain.
history
Even before ESO was officially founded in 1962, the search for a promising location for an astronomical observatory in the southern hemisphere began. After an initial search in South West Africa (now Namibia ), political pressure soon turned interest in more favorable locations near the coast of northern Chile. Finally, the decision was made in favor of the Cinchado , about 160 km north of La Serena , also known as La Silla (Spanish for the saddle) because of its shape, as the location of the ESO observatory. In 1969 the observatory on La Silla was opened.
present
La Silla is home to many telescopes, some of which were and are operated by ESO itself and some by other institutes and universities. Many smaller telescopes have since been shut down, but La Silla plays even in the age of the Very Large Telescope of the Paranal Observatory nor the ESO an important role.
