Question

Quizplus · Accepted Answer

Light pollution refers to the interference of artificial light with astronomical observations, making it more difficult to see stars, planets, and other celestial bodies clearly. This is caused by the use of excessive and poorly directed outdoor lighting, which creates a bright glow in the night sky and reduces the contrast between stars and the background, making it difficult for astronomers to observe the cosmos.
