The maps of visible light show concentrated human habitation on Earth. Here’s another great picture of the entire planet at night showing visible light. It’s a very interesting topic, if you like to read and be informed on new things, anyway.Īside from detriments to astronomy and health, light pollution is also a tremendous waste of energy to send unused and unnecessary light into the sky.

This is not a “NASA” term, though I agree that pollution is negative in all forms. Isn’t science cool?Īnd if you want additional nice wallpapers, check out some other night shots of the planet or browse our many wallpaper posts here.Īlan, it sounds like you have never heard of the term “light pollution” before.
