Content last reviewed: August 2026

Astronomy studies celestial objects and phenomena, planets, stars, galaxies, and the universe's structure and history, applying physics and math to observations gathered through telescopes and increasingly large datasets. Many programs are offered jointly with or as a track within physics.

Coursework blends physics theory with observational technique, using telescopes, analyzing astronomical data, and often programming to process large datasets from surveys or simulations.

Typical courses you might take

  • Introduction to Astronomy
  • Classical Mechanics
  • Electricity & Magnetism
  • Astrophysics
  • Observational Astronomy
  • Stellar & Galactic Astronomy
  • Mathematical Methods for Physicists
  • Research Project
