All of our programming is free and open to the general public. Seating is on a first-come basis. Our regularly scheduled planetarium shows occur at 8 PM on the first and third Saturdays of each month, except when they fall on Chrismas Eve, Christmas Day, or New Years Eve or Day. Directly after each show, if the skies are clear, the public is invited up to the roof to view the night sky through a variety of telescopes and other instruments. We also offer free planetarium shows, observing sessions, and hands-on astronomy workshops to school and public groups as our schedule allows. To book a special group event, use the mail link in the menu bar on the righthand side of this page.
