The Astronomy Union (AU) is the official course union for all full-time undergraduate students in the Faculty of Arts & Science (St. George campus) enrolled in an astronomy course and/or program of study (POSt). We facilitate communications between students and the David A. Dunlap Department of Astronomy & Astrophysics and strive to maintain a lively and enriching community of undergraduate astronomy students at UofT via our shared love for the subject.

Events we commonly organize and run include: academic seminars, observation nights using UofT’s observatories, themed movie nights, workshops, and information sessions about graduate schools and internships in the field, as well as other joint social collaborations with the Physics Students’ Union (PhySU), the Mathematics Union (MU), or the Astronomy and Space Exploration Association (ASX). One of our most long-lived events is the monthly “tAUlks” that we organize to provide undergraduate students with a safe space to discover and share scientific articles, including their own research.

You do not need to be a member of the union to participate in our events, but membership is required in order to hold an executive position or vote in elections and referenda.
