"Next door is the Shedd Aquarium, where you can meet 32,500 creatures from aquatic habitats around the world including beluga whales, dolphins, sea otters, sea lions and penguins inside the Oceanarium. Just beyond the aquarium is the Adler Planetarium, which when constructed in 1930 became America's first planetarium. The building is more than a museum; it is a laboratory, a classroom, and a community exploring the Universe together. Each year half a million visitors experience the museum's interactive exhibitions, live planetarium shows, hands-on educational programs, and world-class collections."
