Fiske Planetarium is located on the campus of the University of Colorado, in Boulder, Colorado. First opened in 1975 with a generous donation from Wallace Franz Fiske (class of 1917), Boulder's Fiske Planetarium hosts a diverse range of shows, star talks, LASER shows, and special live events.
Our planetarium's 65-foot diameter dome (the largest between Chicago and Los Angeles!) was for many years home to one of the few Zeiss Mark VI Star Projectors, affectionately known as "Fritz," after the German engineer who oversaw its installation. In 2013, Fiske completed a major systems upgrade with an 8K Sky-Skan projection system that allows us to show the most cutting-edge content in a truly immersive environment that fully surrounds audiences with a huge screen, dazzling visuals, and fantastic sound. The new star machine, which looks like R2-D2, shows 10 million stars and the Milky Way, the most beautiful indoor sky ever.
Fiske Planetarium works to serve CU faculty and students, local schools, and the general public. We host special talks and educational events, and often host large crowds during astronomical and NASA-related events.
Fiske is open weekdays for select shows and events, and hosts weekend shows and matinées. On weekend evenings and late nights Fiske often hosts laser shows, "Liquid Sky" psychedelic music shows and a topical discussion of the night sky on Thursday evenings.
Our sister facility next door and up the hill, CU's Sommers-Bausch Observatory, hosts free telescope viewing on Friday evenings, weather permitting.
