On November 11, billions of miles from Earth, a spacecraft orbiter and lander will do what no other has dared to attempt: land on the volatile surface of a comet as it flies around the sun at 41,000 mph. If successful, it could help peer into our past and unlock secrets from our very origins. The stakes couldn't be higher.

Scientists are only now beginning to understand the most complex machine in the known universe--the brain. Go on a voyage of discovery into the evolutionary history of our last biological frontier. From early civilizations' attempts at neurosurgery to today's robotic laser surgery, revolutionary new techniques are finally unlocking the story of the brain. As a result, we've learned more in the last five years than in the past 100.

Scientists are on the verge of answering one of the greatest questions in history: Are we alone? Finding Life Beyond Earth immerses audiences in the sights and sounds of alien worlds, while top astrobiologists explain how these places are changing how we think about the potential for life in our solar system.

Stephen Hawking unfolds his personal, compelling vision of the biggest question of all: Who or what created the universe in which we live? The groundbreaking series into the Universe with Stephen Hawking combined cutting-edge computer graphics with Hawking's witty, distinctive and incisive world view. Now, the journey is taken a step further, as physics and cosmology become tools to answer questions that philosophers have struggled with for thousands...

"On December 26, 2004, the world's deadliest tsunami hit the coast of Thailand. Nearly a year later, a team of dedicated scientists has come together to determine the exact cause of the catastrophe, where the next tsunami may strike and how it can be prevented. Join divers as they head to the ocean floor to investigate a critical seabed, one larger than the entire Alps mountain range and likely a key component in the development of Asian tsunamis....

The eruption of Iceland's Eyjafjallajökull volcano in 2010 turned much of the northern hemisphere into an ash-strewn no-fly zone. Katla, an Icelandic volcano 10 times bigger, has begun to swell and grumble, and Hekla and Laki, could erupt without warning. Iceland is a ticking time bomb: When it blows, the consequences will be global. What can we do to prepare for the coming disaster?

The film features exclusive access to Hawking's life story, told largely in his own words. It includes dramatic accounts of his life from childhood through university, intimate footage of Hawking today, including his home routine and his work life at the University of Cambridge, archival footage and candid insights from family members, friends and colleagues.

Unearths the stories behind three of the world's greatest engineering marvels - the Colosseum, Chartres Cathedral, and the Great Pyramid of Giza.

Is the apparent 'grand design' of our universe evidence of a benevolent creator who set things in motion, or does science offer another explanation? Delve into the mind of Stephen Hawking as he attempts to answer some of life's biggest questions: Is there a god? What is the meaning of life? And why does the universe exist?
