The Cornell Astronomical Society & Fuertes Observatory
The Cornell Astronomical Society (CAS) has conducted public viewing nights at Cornell University's Fuertes Observatory for over 50 years. We open the observatory every Friday night during the academic year from 8 PM until midnight, regardless of weather. During the summer, winter, and other Cornell breaks, we generally try to be open from 8 PM to midnight if the weather is clear. To find out if the observatory is currently open, check our Twitter or join our listserv at the bottom of the page for weekly updates on events!
Visit our Hours & Directions page for directions to the observatory/parking information, the Open House page for what to expect when there, and our Event Calendar for a schedule of upcoming events.
Lectures to the public are given by Cornell astronomy faculty and other researchers several times throughout the semester on Friday nights, prior to the open house. Visit the Lecture Series page for a list of upcoming lectures.
The Cornell Astronomical Society is Cornell's astronomy club. All Cornell students, regardless of prior experience or area of study, are welcome to become members of CAS. Visit About the Club for more information on CAS, including meeting and membership information.
Fuertes Observatory Tours and Group Events
Organizations and informal groups may request an educational observing session at Fuertes Observatory conducted by CAS volunteers. These can be arranged on non-Fridays and any night when the observatory is not reserved for introductory astronomy classes. Private sessions are completely free! Scheduling of events is subject to the availability of CAS officers and to the full discretion of the Cornell Department of Astronomy. Send us an email to arrange an event.
