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.


We are happy to announce that, for the first time since Fall 2019 we are once again able to offer Public Nights at the Macalester Observatory for the Macalester community! We welcome all Macalester students, faculty and staff to attend these events.

As part of Macalester’s continued response to COVID-19, all campus buildings remain secure, and can only be accessed by MacPass card access. Unfortunately, this means that our Public Observing Nights are not available to the general public at this time.

For more information, as well as any announcements about when we are able to open our Public Nights to the general public, please check the Public Observing Nights page.
