Astro-Bubble

Welcome to the Astro-Bubble!

The Astro-Bubble is a portable, inflatable planetarium, operated by the Waterloo Centre for Astrophysics. Step inside and explore the Universe!

Inside our planetarium you'll learn how to find the stars, planets and galaxies in our sky, how astronomers have been studying the night sky for thousands of years, and about beautiful and strange objects in our Universe like nebulae and black holes. 

The Astro-Bubble is available for public events, school visits, and for groups of Guides/Scouts -- we will be booking in events for 2024 in the next few months. Please contact wca.outreach@uwaterloo.ca for any general enquiries.
