Why can we see hundreds of stars in one part of the world and barely any in another?

Question

Why can we see hundreds of stars in one part of the world and barely any in another?

In: Biology

Answer 1

Light pollution. In more inhabited parts of the world there tends to be more light generated by humans (street lights, buildings, etc.). This light is from our perspective stronger than the star’s light, thus over-brighting the star. You can think of it as you wouldn’t see small flashlight’s light in a sunny day.

And on the other hand, you have parts of the world with less light generated by human, thus you can see more stars
