The department operates an astronomical observatory that is primarily used for teaching observational astronomy, public education in astronomy, and modest research projects.
It is located on the roof of the 22-storey Loyola residence tower and was made possible by an anonymous benefactor who wished to honour Fr. Burke-Gaffney, Saint Mary's University's well-loved astronomer. It was originally installed in 1972 with a 0.4-metre Ealing cassegrain telescope, but was extensively upgraded and renovated in 2013 and now contains a Planewave 0.6-metre CDK24 telescope.
