Have you looked up lately and counted the stars? Chances are, if you live in or near a big city, you can only see a few of the millions of stars and planets that fill the night sky. Light pollution can obscure all but the very brightest stars, and most cities do not control excess or unnecessary night lighting. When you venture out into more uninhabited areas, the night sky comes alive with an uncountable number of stars. The Chiricahua Mountains are in an area of spectacular, dark night skies. Some of the world's largest telescopes are located on nearby mountains for just this reason.
People have always looked to the stars - whether to navigate, to worship, or to mark the passage of time or season - it seems a timeless way to dream about and ponder at the vastness of the universe. A visit to the monument is not complete without looking skyward into the dark night sky!
Natural night skies, unhampered by light pollution, are an important resource the National Park Service strives to protect. Plants and animals (and humans) have evolved over millions of years to life with dark nights and bright days. When our eyes are exposed to bright lights at night, especially LED lights with a blue hue, our normal rhythms are disrupted. Exposure to light at night for humans can cause health problems. Light at night for animals turns night into day, with consequences for migratory birds, predator/prey relationships, and population sizes. Luckily, light pollution is completely reversible, unlike some of the other human-caused pollutions. See how you can limit light pollution today!
