Question

Quizplus · Accepted Answer

Placing astronomical telescopes and detectors on satellites allows them to get above the absorption in Earth's atmosphere, which can distort or block the wavelengths of light they are trying to observe. This also helps to avoid the effects of dust and haze in Earth's atmosphere on observations. Light pollution is not a major concern for satellites since they are already located far from city and built-up areas. Getting closer to the objects being viewed may not be necessary or even possible for some astronomical observations.
