This book covers the topic of Telescopes in Space. Observation of the night sky's started way before Civilization. Early humans looked at all the lights in the sky, saw that some moved, and some were fixed. What did it all mean?

The initial assumption was that the Earth was the center of the Universe, and everything traveled around it. But, by observations, some “heavenly bodies” wander about in the sky, and increasingly complex theories were developed to address this. Later, when the Earth was dethroned as the center of the universe, it was understood that other planets and the Earth were in orbit around the Sun. And, the Sun was just another star, like those that could be seen in the night sky.
