Astronomy from space vehicles is particularly useful because the telescope
A) is in a gravity-free state; the mirror is not distorted by gravitational stress and can therefore produce sharper images.
B) moves smoothly and without vibration in a constant orbit and can therefore produce sharp photographs.
C) is above Earth's absorbing and distorting atmosphere and can measure radiation over a very wide wavelength range.
D) is in a clean, dust-free environment and scattered light is much reduced.

Question

Quizplus · Accepted Answer

Telescopes in space are above Earth's atmosphere, which absorbs and distorts light, allowing them to observe a wider range of wavelengths more clearly than ground-based telescopes.
