À propos
Faits rapides: Twice a year during the equinoxes, the sunset aligns perfectly with the city's grid so that the sun drops directly into the Rio de la Plata horizon as seen from this planetarium. The Planetario Galileo Galilei was the first major public building in Latin America built with a fully computerized projection system for its dome.
Points forts: On March 20 and September 22, the planetarium transforms into a celestial observation deck as hundreds gather to watch the sun sink into the horizontal line of the Rio de la Plata, a phenomenon made possible by Buenos Aires' precise east-west street grid. The planetarium's architects designed the reflecting pool in front specifically to mirror the sunset colors, creating a double horizon effect that doubles the visual drama.
