The Planetarium’s Zeiss projector reproduces the sky as seen by the naked eye and other celestial phenomena. Star gazers of all ages can explore the splendour of the universe under the vast hemispherical dome of the Star-Theatre.

Since it first opened in 1992, some 13 million visitors have travelled through this "house of life", dazzled by the discoveries that await them along a path reflecting a concept unique in the world. Here, plants and animals by the thousands, cliffs and waterways, even the climate itself recreate with stunning realism the four finest ecosystems of the Americas. Guides are experienced biologists who can answer visitors' questions.
