image of a planetarium

A planetarium theater is a special room with a round ceiling (dome) and a special projector at the center which can recreate the night sky up on the dome by projecting the images of the stars, planets, the sun, and the moon. The projector can be set to show the sky for any date, time, and latitude.

Our planetarium is augmented by our 3-screen video system. The planetarium is an excellent tool for exploring various aspects of astronomy and space science.

This planetarium seats 60 and serves approximately 20,000 pre-school through adult visitors each year and has been open since 1966. The 30-foot dome is illuminated by a Spitz A3P Star Projector and an array of auxiliary projectors. Reservations can be made to bring your group to participate in a program at the planetarium.

In addition to program offerings, the planetarium also serves as a resource for teachers, students, and the general public--including monthly public programs. Please feel free to contact the planetarium via phone, fax, or email if you need any astronomical/space science related information or materials.
