Time-lapse by Pete McBride pedromcbride | About 80% of Americans can't see the Milky Way from where they live due to light pollution. Besides obscuring the beauty of the night sky, artificial light can have other adverse effects, such as confusing wildlife as they try to navigate or mate. All the more reason to protect the dark skies that remain—as one of the few places in the country where artificial light doesn't cover up the stars, Grand Canyon National Park has been designated as a "dark sky park" by the International Dark-Sky Association.
