Every year, thousands of Antarctica's emperor penguins make an astonishing journey to breed their young. They walk, marching day and night in single file 70 miles into the darkest, driest and coldest continent on Earth. This amazing, true-life tale is touched with humour and alive with thrills. Breathtaking photography captures the transcendent beauty and staggering drama of devoted parent penguins who, in the fierce polar winter, take turns guarding their egg and trekking to the ocean in search of food. Predators hunt them, storms lash them. But the safety of their adorable chicks makes it all worthwhile. So follow the leader... to adventure!!

Part of the original team returns to find out more about this bizarre phenomenon. It's mission impossible to access the crocs world and there's no way of knowing what they might find.

L'Europe à la reconquête de la biodiversité

Fifteen years ago, a handful of African Penguins, normally found only on remote islands off the Southern African coast, stumbled across on of the Cape's most beautiful and popular tourist beaches. They swam, they saw, they conquered. And today, Boulders beach is home to more than 4,000 of these delightful, resourceful and entertaining seabirds who live side by side with their human neighbours -well, most of the time! These knee-high invaders not only share the beach, they dodge traffic, scale fences, and take over gardens, the golf course and even the occasional bedroom! For the two feathered stars, Henry and Margot, it's a tale of romance, the challenges of parenthood, separation and a penguin's worst nightmare, oil.

Geheimnisvolle Eichhörnchen

This is a documentary about the expedition of Sebastien Roubinet et Rodolphe André who have decided to cross the Arctic Ocean from Alaska to the Norwegian islands of Spitsbergen, via the geographic North Pole! For this, Sébastien Roubinet has invented a strange little boat "TiBabouche" capable of sailing on sea and on ice. This boat is a prototype brimming with technology and science, made-up by Hervé Le Goff, a CNRS engineer. It will allow Hervé to calibrate the satellite “Cryosat”, the first one capable of measuring the thickness of ice.

To be the first in history of mankind to take a sailing vessel to the Pole. One of the greatest maritime adventures ever undertaken: to cross the Arctic Ocean from one Land to the Other without assistance.

A group of scientists are thinking outside the box for ways to reverse the effects of global warming. And who better to save the earth than National Geographic Channel's host of the World's Toughest Fixes, Sean Riley? He'll join these experts in the labs and in the field to see what wacky new technologies are being developed, like sending mirrors into space and reducing the greenhouse emissions chickens produce.

In 2009 a team of British cavers went on an expedition deep within the jungle of central Vietnam. To their amazement they discovered an enormous cave which they believe to be the biggest in the world. The team, the first humans ever to enter the cave, traveled 6 kilometers underground until their way was blocked by a gigantic rock face they dubbed 'The Great Wall of Vietnam'. Now they have returned, but this time with the right equipment to climb the wall and with a geologist and zoologist to discover if this is indeed the Biggest Cave in the World and what secrets lie deep within?

It is one of the most controversial issues of our day, jeopardizing the health and smearing the reputations of Olympians, professional sports players and even high school athletes. The government has declared them illegal without a prescription, athletes call them unfair, and some doctors say they are potentially deadly. What are the real dangers of these drugs? We've seen what's happening outside the body; now NGC reveals what's happening inside the body, in the Science of Steroids.

1947. The rush to the poles marked the beginning of an incredible human adventure to discover the last-remaining unknown lands.
