Photo of the planetarium


The Southwest Minnesota State University Planetarium is a theater of the universe. It can surround you with an accurate image of the sparkling night sky as well as display the complex motions and cycles that take place around us. State-of-the-art technologies create a fully immersive multi-media experience.

The three primary projection systems include a laser phosphor digital fulldome system, an LED driven optical-mechanical star projector offering the most pristine look at the night sky, as well as a full-color laser light show system that can fill the entire dome with mesmerizing laser light. To augment this experience a powerful audio system enhances the impact of the experience as you take in the wonders of the cosmos. This unique experience will interpret the universe in a way that appeals to both the mind and eye. The Planetarium will introduce you to a life-long acquaintance with the sky and the dynamic universe we are a part of.
