The Saunders Planetarium

Discover the stars and gaze in awe at the Universe as you tour the night sky with a MOSI astronomer!

Lean back as we turn off the lights and use our state-of-the-art star projector to simulate the night sky from any place on Earth, at any time in the past, present, or future!

Take a tour of the night sky, guided by one of MOSI’s expert astronomers, and gaze in awe at the Universe as you discover the stars and planets.
