The California Academy of Sciences is the only institution in the world to combine a museum, aquarium, planetarium, and world-class research and education programs under one roof. This unique combination allows visitors to explore the depths of a Philippine coral reef, climb into the canopy of a Costa Rican rainforest, and fly to the outer reaches of the Universe—all in a single visit. Located in San Francisco’s Golden Gate Park, the building sets a new standard for sustainable architecture and received the highest possible rating from the U.S. Green Building Council. It also provides a home for research scientists, who launch dozens of expeditions each year to document biodiversity around the world, as well as the museum’s 26 million research specimens—essential tools for comparative studies on the history and future of life on Earth.
