Permanent Exhibits

The museum's exhibitions are housed in 16 permanent galleries. There is also a changing exhibition hall, an outdoor science garden, nature trails, a state-of-the-art planetarium, and an observatory. The major overarching theme to the exhibitions is the interconnectedness in nature. This idea is introduced to visitors in a unique, multi-media theater called the Connections Theater.


Galileo Galilei was an Italian astronomer, physicist and engineer who has been called the “father” of observational astronomy, physics, the scientific method and modern science.

The Galileo special exhibition is a hands-on, interactive exhibition engaging visitors by revealing the secrets of Galileo’s groundbreaking science through interactive experiments and exhibits.

This exhibit runs October 1, 2023 - June 2, 2024.
