The night sky is a vast ocean of celestial objects such as the moon, the bright lights of our closest stars, and the warm glow of neighboring galaxies. Located at the University of Wisconsin Fox Valley, Barlow Planetarium helps uncover the vastness of the universe through a 3-D-capable Digistar projector, which—combined with 10,000 watts of digital sound and a 48-foot projection screen—transports guests into the deepest trenches of space. The facility's star shows include family programs that make astronomy easy to understand as well as feature shows that tickle the minds of more hardened astronomy buffs. Along with celestial exploration, the planetarium transforms with dancing lights and rich sounds during laser shows. These programs add visual touches to music from the likes of The Beatles or Isaac Newton's little-known punk band.

The planetarium also hosts academic programs for grade-school children. These include the Wisconsin Space Academy, in which students build and launch rockets, and the Wisconsin Astronomy Academy, which lets pupils peer through telescopes and discover vending machines floating through space.
