Questions are raised about the search for intelligent life beyond the Earth, with UFOs and other close encounters refuted in favor of communications through SETI and radio telescope such as the Arecibo Observatory. The probability of technically advanced civilizations existing elsewhere in the Milky Way is interpreted using the Drake equation and a future hypothetical Encyclopedia Galactica is discussed as a repository of information about other worlds in the galaxy. The Cosmos Update notes that there have been fewer sightings of UFOs and more stories of abductions, while mentioning the META scanning the skies for signals.

Sagan reflects on the future of humanity and the question of 'who speaks for Earth?' when meeting extraterrestrials. He discusses the very different meetings of the Tlingit people and explorer Jean-François de La Perouse with the destruction of the Aztecs by Spanish conquistadors, the looming threat of nuclear warfare, and the threats shown by destruction of the Library of Alexandria and the murder of Hypatia. The episode ends with an overview of the beginning of the universe, the evolution of life, and the accomplishments of humanity and makes a plea to mankind to cherish life and continue its journey in the cosmos. The Cosmos Update notes the preliminary reconnaissance of planets with spacecraft, the fall of the Berlin Wall and the end of apartheid in South Africa, and measures towards the reduction of nuclear weapons.

Having explained the science behind global warming, and addressed the arguments of the climate change sceptics earlier in the series, Dr Iain Stewart concludes the series by looking at the biggest challenge now facing climate scientists - Just how can they predict exactly what changes global warming will bring?
It's a journey that takes him from early attempts to model the climate system with dishpans, to supercomputers, and to the frontline of climate research today: Greenland. Most worryingly he discovers that scientists are becoming increasingly concerned that their models are actually underestimating the speed of changes already underway.

The film looks at the concept of the corporation throughout recent history up to its present-day dominance. Since the late 18th century American legal decision that the business corporation organizational model is legally a person, it has become a dominant economic, political and social force around the globe.
This documentary takes an in-depth psychological examination of the organization model through various case studies. What the study illustrates is that in the its behaviour, this type of 'person' typically acts like a dangerously destructive psychopath without conscience. Furthermore, we see the profound threat this psychopath has for our world and our future, but also how the people with courage, intelligence and determination can do to stop it.

The film explores the growth of exponential technology and where it is taking us. It focuses on how future technology could significantly change the two inevitable features of the human experience; punching the clock and fading away. 'The Future of Work and Death' explores how advanced automation, AI and technological singularity could be achievable in the next 30 years.
How job obsolescence and technological unemployment could consequently occur and how digital immortality can occur may not be a thing of science fiction. But what are the socio-political repercussions of these innovations and are we ready for them? Does working less mean living more and is ending ageing incumbent on us? Worldwide experts in the fields of futurology, anthropology, neuroscience and philosophy share their thoughts on these future advancements.

From executive producers Tony Scott and Ridley Scott comes a special about the battle that changed the course of the Civil War and the future of the Nation. ‘The world will little note, nor long remember, what we say here, but it can never forget what they did here.’ Abraham Lincoln's iconic Gettysburg Address frames this epic, feature-length History special.
‘Gettysburg’ looks at this battle from a visceral new perspective, not the generals who commanded from behind the frontlines, but that of the everyday soldiers who fought there, in a confrontation that changed the fate of the nation. Stripping away the romanticized veneer of past treatments, this special conveys new information and honors the sacrifice of those, both North and South, who fought and died there.
Compelling CGI and powerful action footage place viewers in the midst of the fighting, delivering both an emotional cinematic experience and an information packed look at the turning points, technology, and little known facts of perhaps America's greatest battle. Raw, immersive and emotional, this groundbreaking event puts viewers inside the three-day battle where over 50,000 men paid the ultimate price.
