A spectacular journey into the depths of space: In August 1977, NASA launches one of its most daring missions in space flights. The Deep Space orbiters Voyager 1 and Voyager 2 are shot into space. The task of the two orbiters: exploring the outer gas planets in our solar system. More than 30 years later, the two orbiters have traveled a distance of 15 billion miles and still send unique data to Earth. Countless recordings of these orbiters still serve as the only footage of the two planets Uranus and Neptune, and their moons. After more than 30 years of flight Voyager 1 is the farthest from Earth object that mankind has ever created. THE VOYAGER SHOW: ACROSS THE UNIVERSE demonstrates all the technical, historical and astronomical details of the fascinating Voyager missions that continue to this day.

To determine the true age of the Earth, geochemist Clair Patterson developed the uranium-lead dating method to make an unprecedented discovery - calculating Earth's age of 4.5 billion years. But Patterson's groundbreaking discoveries were just beginning. Patterson made it his mission to draw public attention to the detrimental effects of lead in the environment and dedicated his career to fighting against the petroleum and chemical industry, eventually achieving public health's biggest victory of the 20th century.
