The tenth season of this acclaimed series. A users guide to the cosmos from the big bang to galaxies, stars, planets and moons. Where did it all come from and how does it all fit together. A primer for anyone who has ever looked up at the night sky and wondered.
In the first episode, new astronomical research is beginning to reveal an invisible scaffold of dark matter known as the Cosmic Web, an intergalactic network that transformed the Universe from a chaotic Big Bang into the structured beauty of the present day cosmos.

We are living in a new golden age of exploration. Planet hunters are searching far beyond our solar system and they are actually finding new worlds orbiting other suns. Thousands of these alien worlds have already been found, but this is the story of perhaps the greatest discovery yet, a star 40 light-years away with seven Earth-sized planets: Trappist-1.
This new discovery of seven alien Earth-like planets in a faraway solar system is a major milestone in our hunt for extraterrestrial life, and experts investigate the secrets of Trappist -1's mysterious worlds to reveal if we're truly alone in the universe.

An ancient bronze disk adorned with gold may contain the oldest images of the cosmos ever discovered; using new research and the latest tech, experts investigate if this artefact could be the work of a prehistoric astrologer. Is it just a decorative disc or is there some hidden meaning?
A strange 11,000-year-old deer skull can have links to a British Atlantis.

When Homo sapiens, which means 'wise ones,' discovered and controlled fire hundreds of thousands of years ago, everything changed. Fire allowed us to cook food and heat dwellings, and it served as a focal point for storytelling and sharing cultural identity among community members. We don't yet have established parameters for what it means to be 'distinctly human,' It would seem the only thing that separates us from other animals, Neil deGrasse Tyson ponders, is our neurotic need to feel 'special'. Against the backdrop of the Halls of Extinction, Tyson insists that there must be a clear distinction between ourselves and animals that justifies our eating them, wearing them and even bringing an end to their species.
From the birth of the devil in ancient Persia to a searing story of saintliness among macaque monkeys, this episode is an exploration of human potential for change. It concludes with the story of how one of history's greatest monsters was transformed into one of its shining lights.

A humpback whale mother and calf embark on an epic journey from tropical coral paradises to storm ravaged polar seas. Newly discovered coral reefs in Indonesia reveal head-butting pygmy seahorses, flashing 'electric' clams and bands of sea kraits, 30-strong, which hunt in packs. Elsewhere plagues of sea urchins fell forests of giant kelp. Huge bull fur seals attack king penguins, who despite their weight disadvantage, put up a spirited defence.

In every ocean… just beyond our shores…lives an animal with characteristics we think of as ‘human’ – intelligent, social, curious, gentle, and fierce. They build cities, use tools, and collaborate with other species to hunt. They have personalities – some are bold, while others shy. These animals can change their skin colour, texture, and body shape in a blink of an eye and see in wavelengths beyond our vision. Recent studies reveal octopuses’ consciousness, sophisticated decision-making, and unique personalities. On tropical reefs, in frigid waters, from the shoreline to the deep sea and everywhere in between, the octopus have made a home. Join us as we reveal ‘Secrets of the Octopus’.
In the first chapter, whether transforming their body shape and color to disappear or mimicking their deadliest enemy, Octopus use shape-shifting superpowers to survive.
