Welcome to our Website!

We are currently in Phase of Operation Ops_1 (for more details on phases read here). All observations will be taken remotely. More information here.

We are extending the closure of the Clay telescope through March 15, 2021. We will continue to operate the Baade telescope during this period. 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.

If you have any comments or feedback about our website, please send an email to contacto@lco.cl.

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.

The second stage of the APOGEE project comes to an end

After almost 4 years of operations, last January, 2021 was the last night of the APOGEE-2 project, whose first light occurred in March 2017, with regular operations since April of the same year. The second stage of this project operated at the duPont telescope at Las Campanas Observatory since its inception, but due to the spread of Coronavirus around the world, it was halted between March and mid-October 2020.

Astrophysicists discover the most metal-poor globular cluster in the Milky Way’s interior

The study was led by astronomers from the SDSS IV and identified stars very poor in iron content in a globular cluster located in a region of the galactic bulge that is heavily obscured by interstellar dust, making it virtually invisible in the optical. They used one of the twin spectrographs of the APOGEE-2 survey, installed on the du Pont telescope.

Youtube: International Day of Women and Girls in Science

The low presence of women in science is an issue of international concern and the questions we ask ourselves are: Why don’t women choose scientific disciplines? What is behind their preferences and choices? On the International Day of Women and Girls in Science, we invite you to watch this video documentary, in which women scientists from Las Campanas Observatory tell us about their work and analyze the gender gap in science.
This video documentary has interpretation in Chilean sign language.
