The Boulder Astronomy & Space Society is dedicated to the interests of the observers and space enthusiasts of all types in Boulder, Colorado. It is our goal to provide common ground for Boulder's amateur, professional, and academic communities to share their enthusiasm about the universe around us. Our meetings are generously hosted on the University of Colorado campus at Fiske Planetarium and Sommers - Bausch Observatory and are open to students and the public alike. See the Events page for more details.
