When there is less light pollution, you can see loads of stars, but when there is a lot of light pollution, you see much less stars. What is the science behind this?
In: 3
If the air were perfectly clear, light pollution wouldn’t affect you. But since air isn’t perfectly clear, the nearby light reflects off of the particles in the air, creating that “glow” you see around light sources or over cities. That glow drowns out the distant stars, because the glow is brighter than the tiny amount of starlight that manages to make its way to Earth from that far away.
