Light Pollution Throughout The Continental United States
If you’re an outdoor lover who enjoys star gazing at night, we recommend venturing to middle and northwest America, where the light pollution is substantially less than the coastal states east of the Mississippi River. Sadly, according to a 2016 study, scientists estimate that around 80 percent of North Americans can’t see the Milky Way.

But, as geographer Tim Wallace has mentioned, a majority of the states with random light output, such as North Dakota, are due to shale oil extractions and huge commercial buildings, such as airports and power stations.
