Question

Quizplus · Accepted Answer

The equivalent problem for optical telescopes is light pollution. Light pollution is caused by the presence of artificial light sources such as streetlights, building lights, and illuminated signs, which result in a brightening of the night sky and a reduction in the visibility of stars and other celestial objects. This can interfere with optical telescopes, making it difficult to observe faint objects or study their properties in detail.
