The Cullman Hall of the Universe focuses on topics ranging from planets to stars, life on other worlds to current cosmology. The Scales of the Universe exhibit makes comparisons between the size of the Hayden Sphere that hangs over the hall and other objects in the universe presented at appropriate relative scale.

The Hayden Planetarium (often called "The Hayden Sphere" or "The Great Sphere") has, since 2000, been one of the two main attractions within the Rose Center, at the American Museum of National History in New York. The Rose Center for Earth and Space was designed by Polshek and Todd Schliemann, the building consists of a six-story high glass cube enclosing the 87-foot (27 m) illuminated Hayden Sphere, which appears to float, although it is actually supported by truss work. Polshek has referred to this work as a "cosmic cathedral". [Wikipedia]
