Want to Know What's Happening Here?

As Yerkes has become a space at the confluence of culture, art, and science, we have so much going on. From our speaker series to our roster of tours to our star parties, keep up to date by getting on our email list, following us on social media, and visiting us in person. We're forever evolving into a place of diverse programs for kids and adults alike. Writers, artists, sculptors, photographers, musicians, engineers, chemists, tech innovators, and astronomers are collaborating to understand how science inspires the arts and how the arts inspire cosmic discovery. We're eager to work together at this epicenter of BIG IDEAS. What was a dormant institution a couple years ago and a construction site under full restoration just last year is now a vibrant place filled with enthusiasm, focus, and new voices in conversation. Discover what’s happening in Cobb & Hale's three domes and the junction of Olmsted ellipses. More importantly, discover how you can tap into the energy.
