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) trips to Yerkes Observatory in Wisconsin, where participate in workshops and observe the skies through world-class optics. In the 2020-2021 school year, we will be holding all events virtually. See the next sections and join our listhost for more information.

Wednesday observation schedule

On Wednesday night every odd-numbered week, weather permitting, we will be hosting virtual observing using the SEO telescope. Because the telescope is currently undergoing repairs, observations may not begin until later in fall quarter. Links, cancellation info, and other announcements are distributed via the listhost. Observations run from 9:30 to 11:00 PM, and you can come and go as you please.

Monday talk schedule

We will be having virtual talks on Zoom roughly biweekly. Join our listhost for links and more information. If you are interested in giving a talk, contact an officer either electronically or during a RAS event.
