The Exploring the Universe series is a detailed guide to the exploration of space, covering subjects from the birth of the universe and the formation of black holes to astronaut training and space telescopes. Each book includes clear explanations of scientific concepts and theories and informative annotated diagrams. Pioneers such as Galileo and Newton developed and used the earliest optical telescopes, leading to remarkable and controversial discoveries about the stars, planets, and the nature of the solar system. Telescopes based on their designs are still in use today, while powerful radio receivers and orbiting telescopes can detect light and radiation from unimaginably distant galaxies.
