How to See a Black Hole: The Universe's Greatest Mystery

For two years BBC cameras have followed, Dr Sheperd Doeleman of the Smithsonian Astrophysical Observatory and the work of the Event Horizon Telescope project team, a collective of the top scientific minds from around the world. The project combines radio observatories and telescope facilities from around the world to make up a virtual telescope with a diameter spanning the entire planet. This mega-telescope’s ultimate mission is to capture the first image ever of a black hole. Although the concept of black holes has been long assumed to be fact, the Event Horizon Telescope’s success would definitively prove the existence of this scientific phenomena for the first time – and provide clear visual evidence. The programme brings viewers into the laboratories, behind the computer screens and beside the telescopes of what may prove to be one of the great astrophysical achievements in human history.

The Visit: An Alien Encounter

"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.
