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.
PLEASE NOTE: We're sorry. There are no solar eclipse glasses left. We have sold out. All our sources for more glasses have also sold out. Please join us for our Eclipse Party on August 21. We will have telescopes with solar filters visitors can view the eclipse.
