"This film documents an event that has never taken place – man's first encounter with intelligent life from space". We've been fantasizing about an extraterrestrial visit for decades, but what would happen if it actually took place? How would we cope? Should we be afraid? These and many other questions are addressed in this philosophical film about a hypothetical initial contact with aliens. Scientists and space affairs specialists at the UN and NASA and in the British government cooperate in this cinematic simulation of the undoubtedly exciting meeting between extraterrestrial life and humanity. The interviewees speak directly to the unknown entities as if they've already arrived. From their own fields – politics, theology, sociology, biology or space science – they ask probing questions. What are you doing here? Do you have a sense of right and wrong? Do you carry bacteria that could make us sick? Are we hazardous to your immune system? Information specialists in the British government show how a first summit in this situation could go. How do you inform the public? Will countries work together? Is there a danger involved? Above all, the alien visit raises questions about the relation between our own history of exploration, colonization and warfare, and the expectations with which we approach the unknown. This is a journey beyond terrestrial perspective, revealing the fears, hopes, and rituals of a species forced not only to confront alien life forms, but also its own self image.

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.

Lunar days are about 14 Earth days long, and when night comes, temperatures plummet. But there are other issues to deal with as well. For instance, how can we overcome the moon's lack of atmosphere; difficult terrain with abrasive particles, and the effects of cosmic background radiation?

On Earth and in the Universe, size matters, but it matters in different ways. In Space, bigger is not necessarily better.

Sagan discusses comets and asteroids as planetary impactors, giving recent examples of the Tunguska event and a lunar impact described by Canterbury monks in 1178. It moves to a description of the environment of Venus, from the previous fantastic theories of people such as Immanuel Velikovsky to the information gained by the Venera landers and its implications for Earth's greenhouse effect. The Cosmos Update highlights the connection to global warming.
