"
The arc of the Milky Way seen from a truly dark location is part of our planet's natural heritage," said Connie Walker, and astronomer from the U.S. National Optical Astronomy Observatory in Tucson, Arizona. Yet "more than one fifth of the world population, two thirds of the U.S. population and
one half of the European Union population have already lost naked eye visibility of the
Milky Way." In these areas, people are effectively living in
perennial moonlight. They rarely realize it because they still experience the sky to be brighter under a full moon than under new moon conditions. "
Reducing the number of lights on at night could help conserve energy, protect wildlife and benefit human health," astronomer Malcolm Smith of the Cerro Tololo Inter-American Observatory in Chile. One study found an increased risk of breast cancer for women living in areas with the most light pollution (
abstract). Some communities are
embracing their dark skies, such as
the New Zealand community of Tekapo, possibly home to first "
Starlight Reserve," waiting on UNESCO's official approval. Not sure where to look
in the vast night sky?
Follow some guidelines, or
check the view in Chile,
Queensland, Australia, or
Texas.
