Welcome to the Waterloo Centre for Astrophysics

    ...where the Universe is our laboratory.

 The Waterloo Centre for Astrophysics (WCA) looks to the cosmos to solve the greatest mysteries of the universe. Here, world-class researchers and students come together in an atmosphere of curiosity, creativity and collaboration; exploring our cosmic origin to truly understand the physical processes at work in the Universe. From black holes to cosmology, we aim to understand what lies beyond the Earth. The possibilities for new discovery are limitless.

The Gustav Bakos Observatory houses a twelve-inch telescope, which is located on the roof of the Physics building. The observatory, in operation since 1967, has been used for research on and teaching about visual binary stars.
