Question

Quizplus · Accepted Answer

Large optical telescopes on Earth's surface are built to collect more light from faint objects, allowing astronomers to observe and study them in more detail. This is important as many astronomical objects emit very little light and are difficult to observe without the use of large telescopes. While reducing the effects of Earth's atmosphere is also a consideration, the primary reason for building large telescopes is to increase their light-collecting power. National prestige is not a scientific reason for building telescopes.
