We're transported to Atka Bay on the frigid coast of Antarctica, where a magnificent colony of emperor penguins embarks on a jaw-dropping journey. These remarkable birds, after three months of oceanic feasting, return to the frozen continent as the waters freeze over. What makes their story even more gripping is that they are the last inhabitants of Antarctica, as other wildlife has wisely retreated to the safer sea.
Narrated by David Attenborough, this extraordinary documentary immerses you in an epic saga of survival, fierce parenting, and unwavering tenacity. Join these resilient penguins as they confront the harshest conditions on Earth, embarking on an unforgettable adventure deep within the icy heart of the wilderness.

The magnificent ringed planet Saturn, along with its more than 80 moons, forms the most dynamic planetary system in our neighborhood. With underground oceans and protective magnetic fields, experts are exploring how this collective of satellites has the potential to rewrite the rules of the Solar System.
The closer that we look, the more we see these extraordinary moons like worlds of their own -- so dynamic, so Earth-like. Almost a billion miles from the Sun, these icy worlds could be home for Life 2.0. The moons of Saturn offer possibly the best chance of finding extraterrestrial life in our solar system. With each new mission, we get closer to unraveling the mysteries of Saturn's moons.

A female Phosphorosaurus hunts lanternfish under the ocean's moonlit surface. Hesperornis hunt for fish until they themselves are hunted by Xiphactinus. A Mosasaurus hunts a group of Tuarangisaurus. Nostoceras hatchlings are at the mercy of the tides and juvenile Pyroraptor. The young Nostoceras that survived find themselves among Baculites and Diplomoceras in their new seagrass meadow home.

The Nazis had relentlessly persecuted German and Austrian Jews, reducing their rights, expropriating their property, choking off their livelihoods, declaring them parasites, not citizens and on the evening of November 9, 1938 Kristallnacht, the Night of Broken Glass, Hitler unleashed Nazi mobs on Jews in cities and towns all over the newly expanded Germany, beating, burning, raping, killing, hoping to drive them all out of their country. Hundreds of thousands of German and Austrian Jews were now desperate to escape the Nazis. They knew their only hope lay in flight into friendly European countries or across the ocean to the United States.
As WWII begins, Americans are divided over whether to intervene against Germany. Some individuals and organizations work tirelessly to help refugees escape. Germany invades the USSR and secretly begins the mass murder of European Jews.

Our frozen planet is changing. In this final episode, we meet the scientists and people dedicating their lives to understanding what these changes mean, not just for the animals and people who live there, but for the world as a whole.
Our journey begins in the Arctic, where every summer huge quantities of ice calve from the edges of Greenland’s melting glaciers. On top of the ice cap itself, glaciologist Alun Hubbard descends into a moulin to try to understand the mechanisms that are driving this historic loss of ice.
Elsewhere in the Arctic, it’s not just land ice that is disappearing. In the Gulf of St Lawrence, Canada, biologists are trying to find out how the loss of sea ice will impact the lives of baby harps. In Arctic Russia, with the loss of summer sea ice, more and more polar bears are arriving on the island of Wrangel. Here, a local ranger and scientists are braving the hungry bears to assess their future survival.
Loss of sea ice impacts not just wildlife but people too. In the remote community of Qaanaaq, Greenland, local Inuit hunters are finding the ice too dangerous to travel and hunt on, risking their traditional way of life. And these changes happening in the Arctic have the potential to affect people far beyond. On Alaska’s open tundra, bubbling lakes hint at the gases being released from the previously frozen soil, including the potent greenhouse gas methane.
There is one place where the full scale of a melting Arctic can be best witnessed - from space. Based in the International Space Station, astronaut Jessica Meir looks down at forest fires across Europe and reflects how our changing weather patterns are interconnected.
Rapid ice loss is also happening across the high mountains of the planet’s continents. Glaciologist Hamish Pritchard uses a sophisticated helicopter-strung radar system to try to quantify how much ice is left in the previously uncharted glaciers of the Himalayas. It’s important as, downstream, some 1.2 billion people rely on glacial meltwater as their primary source of fresh water.
Finally, in Antarctica, we meet Bill Fraser, who has dedicated 45 years of his life to studying the Adelie penguin. Over this period, he has witnessed changes in weather conditions and the extinction of entire colonies. These ‘canaries in the coal mine’ are a sign that all is not well, even in the remotest place on earth. And changes here have the potential to affect all of us, so an international group of scientists is on an urgent mission to assess the stability of a huge body of ice known as the Thwaites ice shelf. If this plug of ice melts and slips into the ocean, it will raise global sea levels, impacting coastal communities across the planet.
The unprecedented changes our scientists are witnessing may be profound, but there is hope that, through a combination of technology and willpower, there is still time to save what remains of our frozen planet.

Antarctica is the most hostile of all earth’s frozen worlds. Yet even here, amongst some of the most challenging conditions on the planet, life finds a way not just to survive, but thrive.
Our journey begins at the far edge of the continent, on its far-flung sub-Antarctic islands. Here we meet king penguins that, to feed at sea, must face the danger of ferocious leopard seals lurking in the shallows. On another island, we witness for the first time male Antipodean wandering albatross partnering up with each other as the females in their population are disappearing due to fishing activity.
Heading towards the continent of Antarctica, we traverse the roughest seas on earth - the Southern Ocean - where we find the rarely filmed Antarctic blue whale, the largest animal to have ever lived. At the edge of Antarctica, the sea is so cold that it freezes over, creating a vital ice platform for a mother Weddell seal to raise her precious pup. Still, she needs to protect him from aggressive males.
In spring, the coast of Antarctica is free of snow, drawing in thousands of breeding chinstrap penguins. Stones are at a premium to build their elevated nests and protect chicks from meltwater. But stealing is commonplace, and to make matters worse, with climate change we find chicks today shivering with hypothermia – a warming Antarctica means increased meltwater. Other residents are facing an uncertain future too, including wave-washing killer whales. We discover that their favourite prey, Weddell seals, are now harder to reach, so instead they are resorting to targeting much more feisty prey, including leopard seals, an apex predator in its own right. This dramatic encounter has never been filmed before.
Travelling into the interior of the continent - into the frozen heart of Antarctica - we find great surprises. This is one of the most volcanic regions on earth, and one of the driest. We reveal unexpected sand dunes, hidden in a rare ice-free valley. Then, on the exposed mountain tops, sticking out from the otherwise ice-covered interior, we find tiny snow petrels, which raise their chicks further south than any other bird, and defend their territory by projectile vomiting!
The greatest revelation lies deep in the interior, beneath the surface of an ice-covered lake, where we discover ancient alien-like structures - giant stromatolites - built by primitive lifeforms. If life can make it here, in the extremes of Antarctica, it raises the possibility that life can exist elsewhere, including in the frozen lakes of distant planets.
