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 Observatory will host Observatory Nights during the fall semester of 2023.

All campus buildings remain secure and can only be accessed by MacPass card access. This means that these Observatory Nights are open to the Macalester community only, and are not available to the general public at this time.
