Las Campanas Observatory

Observatorio Las Campanas is an astronomical research facility located high in the Atacama Desert at an elevation of about 2,500 meters. The station operates multiple telescopes dedicated to optical observation and solar research.

The Carnegie Institution for Science established this observatory in 1969 after light pollution affected observations at its previous location in California. The relocation to Chile provided ideal conditions in one of Earth's driest regions.

The facility contributes to global astronomical research through international collaborations, enabling scientists to study galaxy formation, stellar variability, and supernovae.

The facility sits in a remote mountain location and typically requires advance permission or an organized visit to access. Visitors should prepare for the high altitude and bring warm clothing, as nighttime temperatures drop significantly.

The site will host one of the world's most powerful telescopes: the Giant Magellan Telescope with seven mirror segments, expected to begin operations in the coming years. This instrument will enable deep insights into galaxy formation.
