Physics and Astronomy

Aim for a career with astronomical possibilities.

Do you look up at night and dream of distant galaxies? Do you wonder about the origin of the universe? Explore your curiosity with a degree in Physics and Astronomy at Waterloo.

Complement your foundational studies in physics and mathematics with additional courses in astronomy.

Interested in research? The program’s strong ties to Waterloo’s Institute for Quantum Computing give you plenty of opportunities to get involved in research. Meanwhile, if you opt for co-op, you’ll gain valuable résumé-building experience on your work terms.

Once you complete your degree, you’ll have what it takes to succeed at graduate school or launch directly into a career in fields like aerospace, remote sensing, or astrophysics.

Award-winning teaching

As well as small class sizes, you’ll enjoy great teaching. This is a department that has racked up an impressive eight Distinguished Teaching Awards.

Meet other astro-nerds

Meet students who share your passions in the rocketry club or the space club, or spend some time in Waterloo’s very own Gustav Bakos Observatory.
