Why Dark Skies?

Humans are creatures of light; however, in our modern society, we have lit up the night excessively.  We all know of circadian rhythm and how important light and dark cycles are to our mental and physical health.  The sights, sounds, and smells of night and dark skies also connect us spiritually to the universe and the natural world, inspiring introspection.  Artificial light in our communities also affects wildlife movement, behavior and proper function of natural ecosystems.

What changed?

Many residents move to West Newbury to enjoy its rural and natural landscape.  An important part of this natural landscape is natural light and darkness.  As more people move to Town, we need to be intentional in preserving our dark skies as much as our Open Spaces. While LED technology has advanced energy conservation, it also increased brightness and glare in overall outdoor lighting. 

Both LED, and metal halide fixtures contain large amounts of blue light in their spectrum. Because blue light brightens the night sky more than any other color of light, it’s important to minimize the amount emitted. Exposure to blue light at night has also been shown to harm human health and endanger wildlife.
