Open houses are free, inclusive opportunities to learn more about astronomy and experience the universe firsthand. At each open house, members of SAS operate the telescopes and the planetarium of the Angell Hall Observatory. Visitors can view astronomical objects through the 8" and 0.4m telescopes (weather permitting), watch a planetarium show on a number of interesting topics, or learn about the cosmos from a presentation.

The Angell Hall Observatory is located on the roof of Angell Hall.

The Angell Hall Planetarium is located on the third floor of Angell Hall, in room 3118.
