Planetário

Lonely Planet review

Gávea's stellar attraction, the Planetário (Planetarium) features a museum, a praça dos telescópios (telescopes' square) and a couple of state-of-the-art operating domes, each capable of projecting over 6000 stars onto its walls (40-minute sessions in the domes take place on weekends and holidays). Visitors can also take a peek at the night sky (R$20) through the telescopes on Tuesday, Wednesday and Thursday from 7:30pm to 8:30pm (6:30pm to 7:30pm June to August). The modern Museu do Universo (Universe Museum) houses sundials, a Foucault's Pendulum and other permanent exhibitions, plus temporary displays.
