The Search for Other Worlds
Dennis Fradin tells us the story of those men and women throughout history who have been part of an extraordinary hunt - the hunt for other planets. We learn about the ancient Copernicus and Galileo, who realized that the planets, including Earth, orbit the sun; John C. Adams and Urbain Levarrier, who battled over the discovery of Neptune in the 19th century; ninety-year-old Clyde Tombaugh, who found Pluto in 1930; and the astronomers of today who are making plans to travel to Mars in the 21st century and who are finding new galaxies and planets every day.
