Lights Out: Discover the Hidden Impacts of Light Pollution

Join us for an eye-opening presentation, “Lights Out,” exploring how the glow of artificial light at night affects everything from migrating birds to our view of the Milky Way.

Light pollution—sometimes called “ALAN,” or artificial light at night—disrupts the natural rhythms of wildlife, adds unnecessary CO₂ to our atmosphere, and dims the stars that once guided travelers and songbirds alike. But the good news is that it’s a problem we can all help solve. In this one-hour program, DarkSky Board Member and OPAS Member Patty Griffin looks at how light pollution interferes with the delicate balance of ecosystems, especially for birds navigating by starlight during migration. You’ll also learn simple, practical steps you can take at home and in your community to help bring back the night. The evening will close with a friendly Q&A session.

Come curious, leave inspired—and see how protecting the night sky protects life on Earth.
