Planetario Galileo Galilei, Planetarium in Parque Tres de Febrero, Argentina.
Planetario Galileo Galilei is a planetarium and projection hall in Parque Tres de Febrero, Buenos Aires, Argentina, recognized by its large white dome. The structure rests on three curved concrete arches that rise from the ground and support the main chamber, while gardens and pathways circle the building.
The facility opened on December 20, 1966, to bring astronomy closer to the people of Buenos Aires and encourage scientific interest across the city. Construction took place during a period when several Latin American countries were investing in educational infrastructure for the natural sciences.
The name honors the Italian scientist who used the telescope to observe the heavens and laid the foundation for modern astronomy. Families often visit on weekends to watch the star shows together and learn about the cosmos in a shared experience.
The location sits near several bus lines and the Palermo subway station, making it easy to reach by public transport. Presentations run multiple times each day, and checking the schedule online before visiting is recommended.
The projection chamber holds equipment that casts more than 8,500 stars, constellations, and planetary movements onto the interior of the dome. The technology allows visitors to see the night sky as it appears over Buenos Aires, but also to experience views from other locations on Earth.
