Welcome to CUAS
Founded in 1942, the Cambridge University Astronomical Society brings together students and university members passionate about the cosmos. We offer regular talks from leading astronomers, observation nights with historic telescopes, equipment training, and social events throughout the academic year.

What we do

Talks
We invite a variety of people working in astronomy to give talks to the society. The topics are taken from a wide range of areas, from pure astrophysics to the history of astronomy, observing, and much more. Talks are generally about an hour long, including questions to the speaker, and are followed by casual conversation over refreshments. Talks cost £2 or are free to members.

ObsNights (weather permitting) are held at the Institute of Astronomy and combine both tips on practical astronomy with observing at the telescopes.
We also train people to use the telescopes in their own time through Obs demos.
There is also lots of fantastic equipment available for member use.

Social events
The main social events are the Annual Dinner in Lent and the Garden Party in Easter. There is also a squash at the beginning of the academic year and quiz nights throughout the year. Depending on the level of interest, we organise pub meets and/or lunches.
