Longway Planetarium

Featuring 129 seats under an impressive 52 1/2-foot dome, the Longway Planetarium is Michigan’s largest planetarium. For more than half a century, Flint’s Longway Planetarium has been a major resource of science education for students and families. The largest planetarium in the state, it has brought the stars to more than 2.5 million people since its opening on June 26, 1958.

Longway is a prime destination for school field trips and is a popular place for public shows, family science workshops, and community events. With the recent renovation of the planetarium theater, a new Digital Full Dome Theater, Longway Planetarium has become Michigan’s premier astronomy education facility, as well as a multimedia theater for science, technology, engineering and math (STEM) education, lectures, live music, and digital art performances. With the help of its friends, the Longway Planetarium has expanded its role in Sloan*Longway’s Mission: creating engaging experiences for everyone that inspire a lifelong curiosity in history, science, and technology.

Incorporating a new 16 meter dome, new epicentric seating, barrier-free access, and a digital 15,000 watt Dolby 7.1 surround sound system, the Full Dome Theater is capable of accommodating a wide range of programs – from lectures to film series to live performances. But first and foremost, the planetarium is a remarkable education resource, allowing visitors to explore their universe and study history and science through traditional live discussions and immersive virtual journeys – from exploring the far reaches of the cosmos to traveling through the human body inside a cell.
