The Las Campanas Observatory (LCO) welcomed the first-place winners of the XIII School Astronomy Congress, who took part in a two-day, one-night immersive experience at its facilities in the Atacama Region. The congress was held on November 21, 2025, at the University of Concepción, organized by the Millennium Nucleus TITANS and the Department of Astronomy…
The Carnegie Science Las Campanas Observatory (LCO), located in Chile’s Atacama Desert, is one of the world’s premier astronomical observing sites, renowned for its exceptionally dark skies, stable atmosphere, and outstanding seeing. LCO enables cutting-edge research across a wide range of astrophysical fields using a suite of powerful, state-of-the-art telescopes, including the twin Magellan Telescopes…

A record-setting pristine star provides a window into the dawn of stars and galaxies in the universe. This groundbreaking find connects the work of two telescopes at Carnegie Science’s Las Campanas Observatory—the du Pont, where spectra for the Sloan Digital Sky Survey-V are taken, and the state-of-the-art Magellan Clay. An unusual team of astronomers used…
The Swope telescope at Carnegie Science’s Las Campanas Observatory in Chile—one of the world’s leading centers for astronomical observation—has witnessed significant scientific and technological advances since it saw first light in 1971. But it has also been the setting for human stories that accompany that evolution, including many career highlights for the observatory’s Resident Astronomer…
The development of MACO enables real-time optimization of the Magellan telescopes’ performance, strengthening scientific operations from Chile. Carnegie Science Las Campanas Observatory (LCO) has taken a key step in modernizing its operations with the implementation of MACO (Magellan Active Optics), a new active optics system designed to improve the quality of observations with the Magellan…
With a large turnout and a diverse scientific program, the city of Vallenar hosted the first edition of the Astronomy Festival 2026, a public event that brought together families, students, and astronomy enthusiasts to explore and learn about the Universe. The event was organized by Las Campanas Observatory (LCO), the Giant Magellan Telescope (GMTO), and…
A team of astronomers, including Carnegie Science’s Jeff Rich and other former Carnegie Observatories astronomers, have for the first time traced the history of a galaxy outside our own Milky way by studying chemical fingerprints in deep space, a new approach they are calling “extragalactic archeology.” Their findings are published in Nature Astronomy. “This is…
The Henrietta Infrared Spectrograph will study alien atmospheres in unprecedented detail, transforming how we understand worlds beyond our Solar System. For centuries, people have looked at the night sky and wondered what worlds might orbit other stars. In the past few decades, that question has shifted from imagination to discovery. Thousands of planets have now…
