Question

Few people today know that the Milky Way is a spiral arm of our galaxy, which contains such a dense cluster of stars that in the past it appeared not as individual points of light but as a splash of light across the night sky. Why is it no longer visible this way?

Answer 1

The correct answer is : Light pollution

Step-by-step explanation:

This kind of pollution refers to an excessive obtrusive artificial light usually coming from outdoor. Now it is seen as individual points of light because this environmental problem washes out our view of outer space. It can confuse the sight of humans and animals affecting how we perceive things.
