Infographic illustrating effects of light pollution on star visibility

This infographic illustrates the effects skyglow, caused by light pollution, has on star-count. An analysis from Globe at Night, a citizen-science program run by the U.S. National Science Foundation’s NOIRLab, found that to the human eye, artificial lighting has dulled the night sky more rapidly than has been indicated by satellite measurements.
