One hundred years after Columbus' arrival in the Caribbean, Spanish Conquistadors and Priests, push into North America in search of gold and to spread Catholicism. With the arrival of the British in North America, the two colonial systems produce contrasting societies that come in conflict as Manifest Destiny pushes the U.S into the Mexican territories of the South West. As the Gold Rush floods California with settlers, complex and vital communities are overwhelmed. The elites, including Mariano Vallejo and Apolinaria Lorenzana lose their land. Mexicans and Mexican Americans are treated as second-class citizens, facing discrimination and racial violence. Resistance to this injustice appears in New Mexico as Las Gorras Blancas (The White Caps), burn Anglo ranches and cut through barbed wire to prevent Anglo encroachment. At the same time, New Mexicans manage to transform themselves through education, managing to preserve Hispano culture in New Mexico and their standing in the midst of an era of conquest and dispossession.

Carl Sagan opens the program with a description of the cosmos and the Spaceship of the Imagination. The ship journeys through the universe's hundred billion galaxies, the Local Group, the Andromeda Galaxy, the Milky Way, the Orion Nebula, our Solar System, and finally the planet Earth.

Finally, the Ages of Science are described, before pulling back to the full span of the Cosmic Calendar.

Where did we come from? What makes us human? Groundbreaking investigation explores how new discoveries are transforming views of our earliest ancestors. Featuring interviews with world-renowned scientists, footage shot in the trenches as fossils were unearthed, and stunning computer-generated animation, Becoming Human brings early hominids to life, examining how they lived and how we became the creative and adaptable modern humans of today. In the first episode Selam, the amazingly complete remains of a 3 million year-old child, packed with clues to why we split from the apes, came down from the trees, and started walking upright.

From east to west, via mountains, volcanoes, deserts, lakes and Arctic ice, this breathtaking series uses stunning cinematography to chart the dazzling natural wonders of this vast country. Accounting for around 10 per cent of the world’s dry land, Siberia is famous as a brutally cold place. Yet it is home to a diverse range of habitats and animal life – including musk deer, camels, gazelles and the extraordinary Siberian salamander, which can spend years encased in -40°C ice and still survive.

Famed astrophysicist Neil deGrasse Tyson takes a tour of the Solar System and the known universe establishing the components of Earth's "address" within the Virgo Supercluster. He then shares the story of the person who championed an expansive understanding of Earth's place in the universe by presenting Renaissance Italian Giordano Bruno's vision of the universe as a limitless expanse of space and time. He then makes an exploration into the Cosmic Calendar, which dates back to the dawn of the Big Bang (similar to the presentation from episode 1 of the original series). The episode ends with deGrasse Tyson narrating how he met his mentor Carl Sagan, who hosted the first Cosmos series.
