The Cornell Astronomical Society

Open every Friday 8 PM - midnight.
The last open house before winter break closure is Dec. 15!

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 clouds.

 

During Cornell winter and summer breaks, check this page to see if we're open. Join our listserv at the bottom of this page for weekly updates on events!

 

Visit our Hours & Directions page for directions and parking information, the Open House and Accessibility 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.
