A filmmaker forges an unusual friendship with an octopus living in a South African kelp forest, learning as the animal shares the mysteries of her world.
After years of swimming every day in the freezing ocean at the tip of Africa, Craig Foster meets an unlikely teacher: a young octopus who displays remarkable curiosity. Visiting her den and tracking her movements for months on end he eventually wins the animal's trust and they develop a never before seen bond between human and wild animal.

In the National Geographic tradition of powerful natural-history images and storytelling, this film reveals once-invisible dimensions of nature that are filled with beauty and wonder-and hold secrets crucial to our survival. It shines a fascinating spotlight on objects and events that escape the naked eye every minute of every day. Visually stunning and rooted in cutting-edge research, the film blends high-speed and time-lapse photography, electron microscopy and nanotechnology.

The film explores the eye-opening realm of these creatures to better understand how they evolved. Travelling from the rain forests of French Guiana to the Arctic Ocean, scientists use traditional and cutting edge techniques to examine both modern insects and the fossil record in their search for a single common insect ancestor. Insects are vital to life on our planet, yet almost 40% of known species are in danger of extinction.
Insects are the most diverse group of organisms on Earth. The true number of species is unknown, but some estimates suggest that only a fraction have been identified. They have successfully adapted to every ecosystem on our planet. But insects still harbour many mysteries. Where do they come from? When did they first appear on Earth? How and why have they diversified and multiplied so successfully? At a time when certain insect species are in danger of extinction and there is greater interest in their role within ecosystems, this is the fascinating story of their origins.

When a mysterious cigar-shaped object is spotted tumbling through our solar system, experts race to uncover it's true nature. The object, nicknamed Oumuamua, meaning 'a messenger that reaches out from the distant past' in Hawaiian, was discovered by the Pan-STARRS 1 telescope in Hawaii. Since its discovery, scientists have been at odds to explain its unusual features and precise origins, with researchers first calling it a comet and then an asteroid before finally deeming it the first of its kind: a new class of 'interstellar objects.'
A recent paper by researchers at the Harvard Smithsonian Center for Astrophysics raises the possibility that the elongated dark-red object, which is 10 times as long as it is wide and travelling at speeds of 196,000 mph, might have an 'artificial origin.' The theory is based on the object's 'excess acceleration,' or its unexpected boost in speed as it travelled through and ultimately out of our solar system.

The season 8 of Space Deepest Secrets shares the stories of deep-space explorers who are risking their careers, and even their lives, to lead humanity to worlds yet to be seen.
In the first episode, astronomers are laying the groundwork to locate a new planet for the human race to inhabit, and the more alien worlds they discover and encounter, the more they unmask the mysterious and truly destructive nature of the cosmos.

The film tells the true story of a baby elephant born into a rescue camp in the Botswana wilderness. When she’s suddenly orphaned at one month, the keepers and scientist looking after the herd become tireless surrogate mothers while they fight to save the entire species.
