On this moonless night you can see Mars before it sets in the western sky, learn the late fall constellations, and, with the help of our volunteers, observe many celestial objects through telescopes. See marvels such as star clusters M15, M13, and the Double Cluster. View the Ring Nebula and the Dumbbell Nebula, and, see the Andromeda Galaxy, M31.

Activities are designed for school age children accompanied by a parent or teacher. If skies are cloudy, there will be indoor family activities, including a presentation in the library.

All children must be in the company of an adult. Dress warmly as autumn evenings can be chilly. Hats, mittens, winter coats and sturdy shoes are essential! The cost is $5.00 per teacher or adult, and $15.00 for families.

Yerkes Observatory is located at 373 W. Geneva Street in Williams Bay, Wisconsin. Throughout the year, they offer a variety of programs.
