Watch as a diver plunges into the deepest living coral reef exhibit in the world. Explore the layers of a rainforest canopy and the creatures that call it home. Investigate the great mysteries of the cosmos in our all-digital planetarium dome. As an Academy member, there's always something new to learn—and all the time in the world to explore. Join us and rediscover the wonders of the natural world under our Living Roof while supporting world-changing science around the globe.

Please note that the following exhibits will be closed this week for regular maintenance: Morrison Planetarium (Feb. 24-26); Naturalist Center (Feb. 25); Curiosity Grove (Feb. 26). We apologize for any inconvenience.
