Planetarium Theater

Join Us to Celebrate our 50th Anniversary

This summer marks the Planetarium's 50th year and to celebrate we're hosting a special anniversary event.

On Saturday, June 10, 2017, we are hosting a 5:30 p.m. social followed by a 6:30 p.m. dinner and program at UMD's Kirby Ballroom. The cost is $30 per person and pre-registration is required. It promises to be a fun evening of connecting with fellow astronomy lovers, learning about the accomplishments of UMD students and their experiences working in the Planetarium and sharing a vision for the future of the Planetarium.

Simply visit, or call 218-726-6086 to register by Tuesday, May 30 and find out more about the event.

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.
