Those who study space, the planets and stars, and the infinite realms beyond our own solar system are astronomers. They play an important role in understanding our Earth, and its place in a universe so vast, it can sometimes defy our understanding. Modern astronomy allows people to see places no human can ever expect to touch, at distances no human could ever expect to travel. It also begs the question: could there be life on another planet? Learn all about the early astronomers and the techniques and tools they used to further the science of astronomy. This title will allow students to understand that natural objects exist from the very small to the immensely large.
