Major or Minor in Astronomy

Astronomy majors and minors learn problem-solving skills and how to apply physics to understanding the Universe around them. Many of our Astronomy Undergraduates do research in the group during the semester or over the summer. Our graduates often go on to graduate school and find jobs at National Laboratories, observatories, industry, and academia.
