The Bachelor of Arts in Astronomy at Boston University is your gateway to exploring the universe—from planets and exoplanets to galaxies and black holes—while building a strong foundation in physics, mathematics, and scientific communication. This program is perfect for students who are curious about the cosmos and want to develop the analytical and technical skills needed for exciting careers in science, technology, or education.
Curriculum Structure:
Year 1: You’ll start with the essentials: CAS AS 202 Principles of Astronomy I introduces you to the fundamentals of astronomy, while CAS MA 123 Calculus I and CAS PY 211 General Physics (or PY 251 Principles of Physics 1) build your math and physics skills. These courses ensure you have the scientific background to understand how the universe works.
Year 2: Your second year deepens your understanding with CAS AS 203 Principles of Astronomy II, where you’ll explore more advanced astronomical concepts, and CAS MA 124 Calculus II and CAS PY 212 General Physics (or PY 252 Principles of Physics 2), which further develop your quantitative and experimental abilities. You’ll also begin to see how astronomy connects with other scientific disciplines.
Year 3: Now you’ll dive into specialised topics like CAS AS 311 Planetary Physics and CAS AS 312 Stellar and Galactic Astrophysics, where you’ll study the physics of planets, stars, and galaxies. CAS MA 225 Multivariate Calculus supports your ability to tackle complex problems, while CAS PY 313 Waves and Modern Physics (or PY 351 Modern Physics I) introduces you to the modern physics underlying astronomical phenomena.
Year 4: Your final year is all about hands-on experience and advanced study. CAS AS 441 Observational Astronomy lets you work directly with telescopes and data, while electives such as CAS AS 413 Extragalactic Astrophysics and Cosmology or CAS AS 414 Solar and Space Physics allow you to tailor your studies to your interests. You can also pursue independent research through CAS AS 491/492 Directed Studies in Astronomy.
