After a 10 year, $488 million renovation the California Academy of Sciences in San Francisco’s Golden Gate Park will open its doors to the public on September 27th as the greenest museum in the world. The transformation combined 12 separate buildings into one structure, insulated with old blue jeans and a “living roof” covered with plants and wildflowers. Inside, guests can visit the largest all digital planetarium using real-time data from NASA, a rainforest habitat complete with macaws, butterflies and tropical fish, an aquarium featuring the deepest interior coral reef ecosystem and a penguin colony. There’s also a cafe and a restaurant serving local and organic foods.
