Dallas Campbell looks back through almost 50 years of the Horizon archives to chart the scientific breakthroughs that have transformed our understanding of the universe. From Einstein's concept of spacetime to alien planets and extra dimensions, science has revealed a cosmos that is more bizarre and more spectacular than could have ever been imagined. But with every breakthrough, even more intriguing mysteries that lie beyond are found. This great journey of discovery is only just beginning.
For centuries the giant planets floated on the fringes of the solar system as distant objects in the eyepieces of astronomers. But in December 1973 mankind had its first close encounter with Jupiter. We chart the story of our discovery of these massive planets, Jupiter, Saturn, Uranus and Neptune.
