Twinkle, twinkle...is that a star?Night sky not as bright as it was once

According to HuffPost, about 2,500 stars should be visible to us at night. But thanks to light pollution, only a few hundred can be spotted with the naked eye in most suburbs.

Light pollution is defined as where the sky is 8% brighter than it naturally would be. From 2012 to 2016, the amount of artificially lighted areas around the world grew a total of 11%.

Now, the majority of Europe (88%) and nearly half of the United States (47%) lives with light pollution each night. Some research suggests the pace of growth in light pollution matches the rates of urbanization.
