CAA Public Events 2019

Young Observer at C16

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

PUBLIC EVENTS

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.

Nancy Atkinson, contributing editor for Universe Today- www.universetoday.com

Eight Years to the Moon: The History of the Apollo Missions

"The stories of 45 engineers and scientists who worked behind the scenes to make it possible to land on the Moon. Many of these people have gone unheralded for their work, but their contributions were vital to meeting the challenges of such an audacious project. These are stories from the 1960's that you won't find anywhere else."

This presentation will be virtual on Zoom:

Lost Siblings of the Sun

Can we find some of the stars that were formed in the same Star Formation Region as the Sun, 4.5 billion years ago? Incredibly, some sober astronomers think the answer is yes, and published a paper to this effect in the Astrophysical Journal. The star is visible to binoculars and should be up at the time of the March public night.
