The Galileo Galilei Planetarium, commonly known as Planetario, is located in Parque Tres de Febrero in the Palermo district of Buenos Aires, Argentina. This building looks like a spaceship, and is home to one of the most sophisticated planetariums in the world. The idea that Buenos Aires should have a planetarium began to take shape in 1958 by an agreement between Socialist Councilman Jose Luis Peña and the municipal Secretary of Culture, Dr. Aldo Cocca. Construction began under the direction of architect Enrique Jan in 1962, and it was inaugurated on December 20, 1966. The museum has a piece of lunar rock which was brought back to Earth by the Apollo XI mission and gifted to the planetarium by Richard Nixon. A metallic meteorite from Chaco Province is displayed on the entrance terrace. The Galileo Galilei Planetarium has a Zeiss projector manufactured by the Carl Zeiss Company. Full HD.
