Astronomy and astrophysics explore celestial bodies like planets, stars, and galaxies, along with the entire cosmos, examining their origins and development over time. Astronomers primarily aim to deepen our knowledge of the universe's physical properties and share these insights with students and the public. Those pursuing an astronomy and astrophysics major should be prepared to take calculus and physics classes early in their college career. This requires completing high school math courses up to analytical geometry and trigonometry, along with physics and chemistry classes. Computer skills are also beneficial. Once enrolled at the university, students can officially choose astronomy and astrophysics as their major through the College of Arts and Sciences.
