How does light pollution affect stargazing?
In astronomy, light pollution is a real and pressing problem. It diminishes the contrast between the dark sky and celestial sources of light, which makes it harder to see the stars. For the amateur astronomer, it is a major problem because access to a truly dark sky is increasingly difficult to find.
