Light Pollution shown on 3D globe

An online atlas of artificial sky brightness is now available from the Cooperative Institute for Research in Environmental Sciences, in a 3D globe version.  The source site says that it will not work in all browsers (particularly Chrome), but I was able to view/navigate/change basemaps successfully with my Chrome interface.    Light pollution is the bane of astronomers, obscuring fainter objects and interfering with observations. As the article in Science Advances puts it, “This atlas shows that more than 80% of the world and more than 99% of the U.S. and European populations live under light-polluted skies. The Milky Way is hidden from more than one-third of humanity, including 60% of Europeans and nearly 80% of North Americans.”
