Las Campanas Observatory
The Magellan telescopes at Las Campanas Observatory.
Las Campanas Observatory is an observatory at an altitude of 2,300 meters on Cerro Las Campanas, 100 kilometers northeast of La Serena, Chile, which was founded in 1971 and is owned and operated by the Carnegie Institution of Washington, DC. It is home to the twin 6.5-meter Magellan Telescopes, the 2.5-meter Ir�n�e du Pont Telescope, opened in 1976, and the 1-meter Swope Telescope, opened in 1971. The clear, dark skies here, and at the neighboring La Silla Observatory and Cerro Tololo Inter-American Observatory, offer excellent seeing unsurpassed anywhere on Earth.
