Light pollution caused by cities’ usage of artificial light creates a halo in the night sky that can be visible for miles to come. In 2016, 80% of the world — and 99% of the United States and Europe — lived under skyglow, an artificially brightened night sky. The bright glow of manmade lighting washes out the Milky Way, posing a dilemma for photographers who travel far distances to photograph the natural sky. Night sky photographers said the trek pays off — the resulting photographs give city-dwellers a glimpse of the natural night sky, aiding their understanding of the very visible impacts of light pollution.
