Where to Book The Cosmic Light Show at Clark Planetarium:

Viator

On Friday and Saturday nights, head out to the Clark Planetarium to experience their cosmic light show, Rock the Dome. This amazing light show is set to songs from the 60s, 70s, 80s, and 90s. With creative laser choreography, you’ll thoroughly enjoy the kaleidoscope of light and sound and rock the night away.

You’ll need to purchase the tickets early as they do sell out. No two shows are the same so you can come back for fun again and again.

In addition to the Cosmic Light Show, Clark Planetarium has three floors of interactive exhibits on Earth, space, and beyond. Entry to the planetarium’s museum is free, and your family can spend hours being entertained about space, planets, and our solar system every day of the week.

Some cool things to do in the museum are to step inside a giant tornado, see one of the largest moon rocks from Apollo 11, control plasma, be a black hole and collect stars in the Gravity Floor interactive digital exhibit, and build and fly a rocket. Check out the IMAX theater to watch shows on moon landings, volcanos, and the cosmic light show.

The Clark Planetarium website has a schedule of events, from reading sessions to art classes and light shows, that take place in the building. Pick the day of your preferred activity and visit the planetarium so you can attend the event at no cost.
