Adjacent to Parque Explora (separate entry ticket required), there’s no lack of ingenuity at this well-conceived planetarium that packs a lot into a quite small space. Dynamic, child-friendly exhibits encourage visitors to explore space, scientific concepts and phenomena—black holes, gravity, holograms, sedimentation, and sand dunes—through interactive exhibits (with accessible information in English). As well as experiencing what it’s like to be caught in an earthquake, children can simulate controlling a space craft as it hovers over Mars, spin marbles into a “black hole” to explore concepts of gravity, and take their own picture orbiting the moon or on Mars. The shows here are well worth it; book in advance, they sell out fast.
