FROM JULY 26, 2022, REMOTE OBSERVATIONS ARE RESUMED
Welcome to our Website!
As of 19 April 2022 the observatory is entering a new Phase of Operation Ops_3 (for more details on phases read here). While the majority of observations will continue to be carried out remotely, requests for on site observations will be considered provided the observer can meet the other guidelines outlined below for either those in Chile or foreign visitors. We remind observers that they should read the Remote Observing Guidelines well in advance of their Magellan run to make sure they are properly prepared for remote observing. Due to ongoing infrastructure renovations, the duPont telescope will remain without nighttime operations until further notice.

Las Campanas Observatory
The Las Campanas Observatory is located at a superb site high in the southern reaches of Chile’s Atacama Desert, and was established in 1969 to be home to both 40-inch and 100-inch reflecting telescopes. The newest additions here, twin 6.5-meter reflectors, are remarkable members of the latest generation of giant telescopes. The future of Las Campanas Observatory will be marked by the construction of the Giant Magellan Telescope (GMT), an extremely large telescope that, with seven segmented mirrors, will be 80 feet in diameter. LCO is part of the Astronomy & Astrophysics division of the Carnegie Institution for Science.
Carnegie Astronomy & Astrophysics
The history of 20th century astronomy is inextricably linked to the Carnegie Observatories. From the revelation of the universe’s expansion to the discovery of dark energy, Carnegie Observatories scientists have transformed humankind’s understanding of the cosmos. The groundbreaking work continues today at our world-famous Las Campanas Observatory in Chile, home to the twin Magellan telescopes, and site of the future Giant Magellan Telescope. Carnegie scientists are still at the vanguard of research on galaxy formation and evolution, the chemical evolution of stars and planets, stellar variability, supernovae, and more.
