Light pollution over the US
Light pollution happens when outside lights, such as a streetlight or a security light, points light upwards into the night sky.

This light gets scattered in the sky and makes an orange foggy glow to appear above a town.

What can happen?

It is likely that we won't be able to see the stars in the night sky if the amount of light pollution isn't closely controlled.
