Yerkes Observatory is partnering with the Geneva Lake Dark Sky Initiative ( for a special August star party. Join us on this summer evening, and gaze upward and see shooting stars streaking across the heavens or view the vivid streak of the Milky Way. Saturn with its many rings will be shining late into the night. Come observe the sky at Yerkes many telescopes!

The Geneva Lake Dark Sky Initiative is a broad-based community movement committed to raising awareness about light pollution in the Geneva Lake area. We will be exploring the effects of light pollution through interactive exhibits on energy, safety, wildlife, and heritage. Also learn about practical lighting solutions to create a more starry sky.

Even if it is too cloudy to observe, there is much to do. Indoors we will be having hands-on activities, presentations, and facility tours. The Yerkes tour features a look at the famous 40-inch Great Refractor within the 90-foot diameter dome.

The cost will be $5 per person, with a maximum of $15 per family. All children must be accompanied by an adult. No pets, please. If you wish, bring your own binoculars, digital cameras on a tripod, or telescope. We can help you to use them.

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