Dark skies have been increasingly obscured by the glow of artificial light. This surge in light pollution affects stargazing as well as the delicate balance of nature. Light pollution is caused by inappropriate or excessive use of artificial light and holds environmental consequences for humans, wildlife and our climate. The remedy lies in understanding and curbing light pollution through responsible outdoor lighting practices.

With nearly 10% of Fairfax County covered by parks situated in diverse environments, adopting dark sky-friendly lighting becomes paramount for ecologically sensitive areas. Light trespass and pollution impact wildlife by disrupting migrating bird navigation and hindering nocturnal animals’ ability to hunt and feed.

There are ways to make an impact and reclaim the night in your community:

• Lights Out Fairfax – March 23, 2024, 8:30-9:30 p.m.
  As our region has expanded, excessive light pollution has dimmed the night sky, impacting both our environment and our connection to the natural world. On March 23 from 8:30 to 9:30 p.m., residents are encouraged to join the initiative by turning off outdoor lights for one hour. By enlisting family, friends and neighbors, we can collectively embrace the darkness and rediscover the beauty of the stars. Once the light goes out, be sure to allow up to 15 minutes for your eyes to adjust, revealing the stellar spectacle that lies above.
  
• International Dark Sky Week – April 2-8
  Following Lights Out Fairfax, the Fairfax County Park Authority will continue its commitment to dark sky conservation by participating in International Dark Sky Week from April 2-8. This weeklong awareness campaign aims to increase understanding about the importance of preserving our dark skies and the detrimental effects of light pollution on human health, safety and the environment.
