Light Pollution News
Ever wonder why migrating birds crash into buildings? Or why you can't sleep at night? What about where you can still see the Milky Way?
Light Pollution News explores how our 24/7 lit world affects everything from wildlife and human health to our understanding of the stars, travel, and the future of our cities. Host Bill McGeeney brings on rotating guests to help dig into the latest research, policy activity, and real-world solutions - from how irresponsible lighting degrades our health to the best dark sky destinations for your next trip. Whether you're a birder, conservationist, astrophotographer, or just someone who misses sleeping in darkness, this is the show that connects the dots between your disappearing nighttime environment and the world around you.
