Bringing the Universe to You

The Marshall W. Alworth Planetarium offers live, interactive shows and full-dome theater presentations. From traditional star displays and cultural shows that show the importance of astronomy around the world, to feature presentations that whisk you through the depths of outer space, the planetarium has something for curious stargazers of all ages.

Located on the main UMD campus, the planetarium has served Duluth for 50 years as a fun and educational resource for school groups from preschool to college.

The planetarium is also home to the Arrowhead Astronomical Society, one of the largest amateur astronomy societies in the Upper Midwest.

We invite you to an unforgettable evening — to experience the fascinating world of astronomy.
