Protecting the Night

The night sky has inspired us for generations. Nighttime views and environments are among the critical park features the National Park Service (NPS) protects. Night sky protection enhances qualities of solitude and undeveloped wilderness character that animals depend on for survival, park visitors seek for connections, and many cultural-historical parks require for preservation. In this regard, the NPS recognizes a naturally dark night sky as more than a scenic canvas; it is part of a complex ecosystem that supports both natural and cultural resources.
