The Ryerson Astronomical Society (RAS) is the University of Chicago's astronomy club. Our club's purpose is to have all humanity (or all University of Chicago students, for starters) observe the celestial luminaries in hushed awe with our antique 6.25" refractor, 10" reflector, and ~60" radio telescope. Our website has information about upcoming club events; details of RAS history; a collection of astrophotographs and RAS photos; the Rchive, a vast index of RAS documents; useful space and astronomy links; and contact information for our members.

Ryerson Wednesdays: Every clear Wednesday night from 7:30 to 10:00 PM we have public observing at our Ryerson rooftop observatory (all the way up the spiral staircase opposite Ryerson 358).

Special events: We usually spend a night at Yerkes Observatory in Wisconsin every quarter to observe on the 24" and 41" reflectors. In spring quarter we have a Friday evening trip open to the public. Over 40 people went on the 2010 trip! We also occasionally visit dark-sky sites such as Willow Slough in Indiana.
