Why is San Pedro de Atacama the best destination to observe the stars?

San Pedro de Atacama, located in northern Chile, is a destination recognized worldwide for its surreal landscapes. The region has been classified as one of the best places in the world for astronomical observation by institutions such as NASA, the European Southern Observatory (ESO), and National Geographic magazine. This has attracted both scientists and travelers seeking an unforgettable experience under the stars. But, what makes this place so special for astrotourism? In this article, we tell you 5 reasons that make San Pedro de Atacama a paradise for astronomy lovers.

1. A sky free of light pollution

San Pedro de Atacama is located in one of the areas with the least light pollution on the planet. Unlike large cities, where artificial light interferes with sky observation, here the stars shine with surprising intensity. Thanks to strict regulations and low population density, this destination remains a sanctuary for astronomy lovers.

2. Altitude favors visibility

With an altitude of over 2,400 meters above sea level, the atmosphere in San Pedro de Atacama is thinner, reducing distortion of starlight and allowing for clearer sky observation. This characteristic makes the observation of celestial bodies such as galaxies, nebulae, and planets much clearer compared to lower altitude locations.

3. Dry and clear weather

The Atacama Desert is the driest place in the world, with over 300 clear nights per year. This means that almost any night is ideal for observing the Milky Way, constellations, planets, and other celestial bodies without the interruption of clouds. The absence of humidity also prevents distortions in starlight, further enhancing the quality of observation.

4. Proximity to astronomical observatories

Chile is home to some of the most important observatories in the world, and San Pedro de Atacama is close to facilities such as ALMA (Atacama Large Millimeter Array), the world's largest radio telescope. This research center confirms the quality of the Atacama skies and has been essential in advanced astronomical research, including the study of protoplanetary disks and the formation of new stellar systems, the exploration of interstellar gas clouds, and the study of galaxy formation.

5. A spiritual connection with the universe

For many ancestral cultures, including the Atacameño people, the night sky has a special meaning. Constellations were used for agriculture, navigation, and spiritual beliefs. Today, that connection remains alive, and several astrotourism tours include stories of Andean cosmology, valuing these tales as an essential part of the experience.
