Welcome to the Astronomy Home

The Astronomy branch of Macalester’s Physics Department provides a variety of courses as well as edifying facilities for students interested in the study of the universe itself.

The Astronomy Emphasis physics major allows interested students to explore both theoretical and observational astrophysics. These classes build fundamental skills that are suitable for graduate study in exciting areas such as planets, stars, galaxies, and the nature of the cosmos itself.


The Macalester College Observatory will be hosting a Public Observing Nights series on Monday evenings from 8:00 – 11:00,  through December 10th, 2018.
