Year 2: In the second year, you’ll start your formal astronomy and astrophysics studies with courses such as AST221H1 – Stars and Planets and AST222H1 – Galaxies and Cosmology. You’ll also take AST320H1 – Introduction to Astrophysics and may begin AST325H1 – Introduction to Practical Astronomy. Physics and mathematics courses continue to support your understanding of the universe’s physical laws.
Year 3: Your third year deepens your expertise with advanced theoretical and practical courses. You’ll study modules like AST326Y1 – Practical Astronomy (which includes hands-on telescope use), AST424H1 – Introduction to Astrophysical Research, and electives in advanced mathematics, physics, or computational methods. This year is designed to give you both theoretical insight and practical research skills.
Year 4: The final year emphasises independent research and advanced topics. You’ll undertake a major research project such as AST425Y1 – Research Topic in Astronomy, working closely with faculty on cutting-edge problems in astrophysics. You can also choose from advanced electives in areas like cosmology, stellar evolution, or planetary science, tailoring your studies to your interests and career goals.
Focus areas: Stellar and planetary science, galaxies, cosmology, observational and theoretical astrophysics, computational methods, and astronomical instrumentation.
