The Planetarium is open to the public for free shows on selected Friday evenings: see <link>. No reservations necessary.
Groups who would like an evening program should request an outreach event from our outreach program at http://lsa.umich.edu/astro/public-outreach/custom-events.html.
Sorry, but we are unable to do school programs or daytime public shows. For daytime shows or school groups, you should contact the Planetarium in the U-M Museum of Natural History at http://www.lsa.umich.edu/exhibitmuseum.
