Club mission

The Ryerson Astronomical Society (RAS) is the University of Chicago's astronomy club. Our club's purpose is to observe the celestial luminaries in hushed awe in our observation dome on the roof of Ryerson Hall, and to spread the love of astronomy and astrophysics through talks and events.

What we do

The RAS holds a Monday evening talk series during the UChicago academic year, as well as public observation on Wednesday nights. No experience or prior interest is necessary for either event, and we encourage everyone to come and participate. Beyond our weekly events, the RAS conducts many other activities in the astronomy and astrophysics realm, which are open to our members. Periodically, we run trips out to dark sky sites in the vicinity of Chicago for better observing. We also run longer (weekend) trpis to Yerkes Observatory in Wisconsin, where participate in workshops and observe the skies through world-class optics.
