The first outdoor lights were installed around 150 years ago, and our night sky has never been the same. With brighter lights at night, it is harder to see dim stars. As a result, only around 20 percent of Americans can actually see the Milky Way Galaxy with their naked eyes.
Even in the smaller towns of the Greater Danbury area, where I live, it is difficult to observe the night sky. Lights at night increase the brightness of the sky, making light pollution an issue predominantly in urban and suburban areas. While artificial lighting can be beneficial for us at night, it is important that we take the appropriate steps to use it in a way that protects our night sky.
