Observatory Open House

NOTE: The Edelman Planetarium is closed effective March 16 - April 30 to protect the health of our visitors amid the outbreak of COVID-19. These events will not be rescheduled.


Observe the evening sky through telescopes during our Observatory Open House nights. Astronomy faculty and club members are on-hand to operate the telescopes and guide visitors as they view objects in the night sky. Our Open Houses are free and open to everyone!

Observatory Open Houses are offered once a month during each semester. They begin in the planetarium with a brief virtual preview of the night sky. Visitors are then escorted to the 4th floor observatory, where they will participate in observations of the night sky.

Attendees observe through telescopes on the observing deck, so be sure to dress for the weather! Weather calls are posted by 2:00 pm.
