Tues. Sept. 8, 2026

5:30 - 6:15 p.m.
​One World, One Sky
​Pre K - Early Elementary Audiences​

​

​One World, One Sky is a fulldome planetarium show that follows Sesame Street's 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.

​7:00 - 8:00 p.m.
​Seeing! A Photons Journey Across Space, Time and Mind
​General Audiences

Stunning 360° visuals of landscapes, skyscapes, wildlife, humanity and space are used to tell the story of light, sight and vision.

We begin with a photon’s creation inside a distant star and follow its immense journey across the galaxy into the eye of a young stargazer. As the photon enters, we learn about the structures of the eye, their functions and we ride along the optic nerve. The photon's energy is converted into electrochemical impulses that travel the neurochemical pathways of our brain, resulting in an image in our mind.

Also addressed are the ways technology enables us to restore vision and prevent various diseases that affect sight.
