Since the beginning of civilization, human nature has been facinated with the mysteries of the universe. While admiring its extent and beauty, we feel the challenge to know it and the desire to discover its connection with us. When we investigate the cosmos we are also inquiring about our own origin. Man probably peered into the sky with wonder before looking over the land, seas and rivers that were much closer. The cycle of seasons, the sun's light and heat during the day and the moon and stars at night, the need to orient ourselves in travels from one place to another and to establish a chronology for events, were reason enough for man to try and find his place in the universe. At first the known universe was restricted to the sun, moon and some planets. But as our ideas evolved and astronomical tools were improved, human knowledge expanded, reviling the Cosmos in a surprising and amazing manner.
