Open Houses

Open Houses typically take place on the second Saturday of every month*, at 7:00 from September-April and 8:00pm from May-August, in Ellis Hall on the Queen's Campus (58 University Ave).  Each month, a featured astronomer presents a hot topic in current astrophysics research followed by a tour of the Observatory facilities!

During the tour, visitors have a chance to look at the night sky using Observatory telescopes (weather permitting), learn about astro-particle research at the McDonald Institute and the history of physics at Queen's University.
