In Defense of Darkness: Protecting the Night Skies of the PNW - Online

When was the last time you stood beneath a truly dark night sky, surrounded by thousands of stars and the shimmering glow of the Milky Way? For much of human history, this was an ordinary experience. Today, increasing light pollution is making it harder to see the stars—and changing the nighttime environment in ways that affect wildlife, ecosystems, and human well-being.

Join astronomy educators and dark sky advocates Linda Kahananui and John Goar for a fascinating exploration of why natural darkness matters and what we can do to protect it. From the remarkable night skies above the Olympic Mountains to the growing glow of cities and towns across the Pacific Northwest, we’ll discover how artificial light is transforming the world after sunset.

Along the way, we’ll explore how light pollution disrupts wildlife behavior, particularly for migrating birds and nocturnal species, while also affecting human health, wasting energy, and contributing to climate change. Linda and John will share practical ways individuals and communities can reduce unnecessary lighting, protect wildlife habitat, and preserve the natural rhythms of night.

Linda is a lifelong amateur astronomer, outdoor educator, and volunteer “Dark Ranger” at Olympic National Park, where she leads night sky programs at Hurricane Ridge. She also chairs DarkSky Olympic Peninsula, a chapter of DarkSky International. John is a retired science and math teacher and lead astronomer at Olympic National Park who has spent more than a decade introducing visitors to the wonders of the night sky through telescope programs and guided full moon hikes.

We’ll also celebrate the cultural heritage and timeless wonder of stargazing, explore what makes the Pacific Northwest’s remaining dark skies so special, and look ahead to notable astronomical events coming in 2027—offering plenty of inspiration to get outside and look up.

Whether you’re an amateur astronomer, naturalist, outdoor enthusiast, or simply someone who appreciates a star-filled sky, you’ll leave with a deeper understanding of the importance of darkness—and practical ways to help protect the wonder of a truly natural night.
