The 1960s-built planetarium, resembling a UFO, is located in the Parque Tres de Febrero in Palermo. It has a main projection room with a 20-metre dome and reclineable seats for viewing projections of the stars and planets, and a smaller room for exhibitions. It also has a museum, a collection of meteorites from the north of Argentina, and hosts interactive exhibits and audiovisual shows.
Extensively renovated in 2017, the planetarium now boasts 4D and robot technology, simulators and cutting-edge projection equipment.
The planetarium is built on the site of the first recorded football match played in Argentina, contested between the Buenos Aires Cricket Club and the crew of the British warship The Bombay on June 29, 1867.
