Explore the night sky with cutting-edge astronomical presentations in the awe-inspiring Fels Planetarium.

Look up and see what the actual night sky would look like without the interference of weather, pollution, or city lights. The immensity and clarity of the view create a sense of wonder and stimulate the imagination. Engaging shows and immersive visuals and sound educate young and old alike about astronomy and our place in the universe. Whether you’re learning about the constellations in our night sky tonight or traveling to the inner reaches of the human body or the outer reaches of the solar system, a visit to the Fels Planetarium will be an experience that you won’t soon forget!
