Celestial Navigation and Stargazing 101

Thursday, September 29 at 6:30 p.m. Johnson Community Room.

Celestial navigation is the science of finding your way by the sun, moon, stars, and planets; it was frequently used in coastal towns like Madison by sailors going to sea. Brian Kohler of Mystic Seaport’s Treworgy Planetarium will teach program participants how to chart a course on the open seas using the vintage tools and instruments that formed the basis for our modern GPS system. Afterward, he will take the audience outside for a stargazing session with one of the Planetarium’s powerful telescopes to experience the highlights of the autumn sky!
