Ever since the planetarium opened in the spring of 1968, our mission has been to bring the joy of discovering the cosmos to people of all ages. 

New planetarium shows are offered every month, tickets for these shows can purchased online or at the door. Free telescope viewing is also available once a month at the Mt. SAC Observatory (weather permitting). Please view our online calendar for more information on these events. 

We offer field trips for school and scout groups that include a planetarium show and rocket building and launching. You can see a list of the dates we currently have available and submit a reservation request for your group online by clicking here.
