Question

Quizplus · Accepted Answer

X-rays cannot pass through the Earth's atmosphere and reach the surface, so X-ray telescopes must be placed in orbit around the Earth to detect X-ray signals from space. X-rays are absorbed by the Earth's atmosphere, so X-ray telescopes must be placed in orbit above the atmosphere to detect incoming X-rays.
