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 for Earth and Space, at the American Museum of National History in New York. The top half of the Hayden Sphere houses the Star Theater, which uses high-resolution fulldome video to project “space shows” based on scientific visualization of current astrophysical data, in addition to a customized Zeiss Star Projector system replicating an accurate night sky as seen from Earth.

The Big Bang Theater occupies the bottom half of the Hayden Sphere. Utilizing a screen that measures 36 feet (11 m) in diameter over an 8-foot-deep (2.4 m) bowl, a four-minute program depicts the birth of the universe, with narration by Liam Neeson. The Big Bang Theater serves as an introduction to the Heilbrun Cosmic Pathway, a spiral which wraps around the sphere, connecting the second and first floors of the Rose Center. The cosmic pathway provides a timeline of the universe's history from the Big Bang to the present day. The Heilbrun Cosmic Pathway is one of the most popular exhibits in the Rose Center, which opened February 19, 2000.

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]
