Learn Our History

The first efforts by professional astronomers in Chile to protect the country's night skies began in the mid-1990s at the Interamerican Observatory of Cerro Tololo and were realized with the establishment of the Office for the Protection of Sky Quality in Northern Chile (OPCC) in the year 2000.

In 2019, a group of astronomers and people concerned about dark skies, with the support of the European Southern Observatory, Las Campanas Observatory, and the Magellan Telescope, came together to create the Cielos de Chile Foundation, with the purpose of deepening the articulation between communities, universities, and public and private institutions, to halt the advance of light pollution.
