For thousands of years humans have looked up at the shadow sky with awe and wonder. As science developed, our geocentric judicial opinion of creations place in the cosmos, changed drastically. In the deep 16th century-- Copernicus, Galileo and Kepler, three great astronomers, found that there was vigor special ab protrude earth, and that it was not the warmheartedness of the universe.

In the late 1970s and the eighties there was to occur a rare geometric arranging of the outermost planets, Jupiter, Saturn, Uranus and Neptune. These four planets would be in line with earth. Scientists and astronomers knowing a mission to take advantage of this occurrence.

In 1977 NASA launched two lieucrafts named Voyager 1 & 2. These two spacecrafts were designed to remain running(a) for 5 years and cond! uct close up studies of Jupiter and Saturn, Saturns rings, and the large moons of the two planets. After ceasing to be operational they would still outride to travel beyond the solar system into outer space eventually passing within 1.6 light years of a star. In the event of their getting intercepted by intelligent beings from approximately other planet, each spacecraft is carrying on board a map of our galaxy showing the location...If you want to get a full essay, order it on our website: OrderCustomPaper.com
