Opening in 1989, the planetarium was named for T.C. Hooper who was instrumental for the early fund raising of monies for many of the facilities now at Roper Mountain, including the planetarium.

The Hooper Planetarium features a Spitz SciDome HD. Visitors will enjoy full-dome, full-color, full-video, surround sound and dynamic programs. Programming includes entertaining, inspiring, and educational classes in astronomy and other sciences for students and the public.
