Rio's planetarium is a great escape if your vacation gets rained on, or if you simply have a passion for astronomy. The adjoining interactive Museu do Universo (Museum of the Universe) illustrates the history of space exploration and travel in a futuristic exhibition area. The planetarium has two projection domes: a 23-meter-diameter Carl Zeiss Universarium VIII as well as a 12.5-meter-diameter Galileu Galilei Spacemaster. The larger dome, projecting around 9,000 stars, is among the most modern in Latin America. The planetarium frequently updates its programming, which consists of a mixture of fictitious adventures in space (recommended for kids) and nonfiction shows about the constellations and our solar system. If your aim is stargazing without the voice-over and music, the Praça dos Telescópios is open for sky observation from Tuesday to Friday, between 7:30 pm and 9:30 pm.
