IMAX at the Smithsonian
The Smithsonian's 3 IMAX® theaters have the largest screens in the Washington, DC region and measure up to 6 stories tall! Our giant-screen films offer an immersive experience that complements the museum exhibits.
The Planetarium's 77-foot digital dome theater is the only full-dome cinema in DC. Audiences can journey through time and space to view some of the most extraordinary images not viewable to the naked eye.
