In addition to being a scourge for astronomers, light pollution also affects nocturnal organisms and the ecosystems in which they live. This new atlas shows that more than 80 percent of the world and more than 99 percent of U.S. and European populations live under light-polluted skies. The Milky Way is hidden from more than one-third of humanity.
Those of us living in cities, towns and villages are subject to varying degrees of light pollution — the inappropriate use of artificial light at night. But we don’t have to lose our stars as there are ways to mitigate the skyglow. Learn what you can do to help during International Dark Sky Week, 4—10 April.
