"This is our Universe, our museum of wonder and beauty, our cathedral."

– John Archibald Wheeler

Young Observer at C16

A young observer peers through the CAA's vintage Celestron 16 telescope.


The CAA hosts at least 12 Saturday Public Observing events featuring a guest speaker that is followed—weather permitting—by celestial viewings through telescopes at the facility. During viewing hours, society members will be available to answer questions and provide everyone with an opportunity to look through the Society's telescopes and those of our members.

This site will be updated through out the year as we assemble our speakers and events.

Here Be Dragons. Unsolved Mysteries in Astronomy

We are living in the midst of a Golden Age in astronomy. From our vantage point in the Milky Way, astronomers have surveyed billions of light-years of space and peered billions of years back in time. Despite the many triumphant discoveries and successful theories, there remains much that is unexplained. This presentation will discuss the unsolved mysteries of what makes up the universe, are we likely to find more planets in the outer solar system, and can we find life beyond Earth.
