In this free planetarium show, join Big Bird and Elmo as they explore the night sky with Hu Hu Zhu, a Muppet from "Zhima Jie," the Chinese co-production of Sesame Street. Together they take an imaginary trip from Sesame Street to the moon, where they discover how different it is from Earth. They also journey to Zhima Jie to learn about the similarities in our view of the sky.

This program runs 25 minutes and is appropriate for families with young children. Tickets are free and only available in person at the planetarium box office.

One World, One Sky is shown on Thursdays and Sundays at 10:30 am.
