Join us for our yearly Perseids Meteor Shower open house on Friday, August 15 from 7:30pm – 9:30pm! We’re thrilled to be joined by our friends at Lake County Astronomical Society and Adler Planetarium, who are volunteering their time to provide observing outside on our South Lawn if clear and hands-on activities inside the building. We’ll also have free face painting on site, a chance to meet astronomer and Y.O. Speaker Series guest Dr. Katie Mack, engaging science demonstrations and activities, and more for your family to enjoy. 

The open house will take place rain or shine. This does not include use of telescopes within the building. Reservations are required, and tickets can be purchased on our ticketing website. Tickets for this event cost $5 per child and $10 for adults and are available online only. There will not be parking onsite at the Observatory. Ticket holders must park at Williams Bay School and board an accessible trolley that will run a continuous shuttle between the school and observatory during the Open House.
