Planetario Galileo Galilei
Palermo
One of the city's most iconic buildings, the Planetario Galileo Galilei is a great orb positioned on a massive concrete tripod in the middle of Palermo's Parque Tres de Febrero. Built in the early 1960s, it looks like something out of Close Encounters of the Third Kind—especially at night, when the dome glows with eerie blue and red lighting. Tickets for the twice-daily sky shows (five times on weekends), narrated in Spanish, go on sale at 9:30 am Tuesday through Friday and at noon on weekends; note that they usually sell out fast. Three meteorites that landed in northern Argentina 4,000 years ago guard the entrance. The nearby pond with swans, geese, and ducks (also lit up at night) is always a hit with kids.
