The Mystery of Chaco Canyon

Blue Peter presenters Helen Skelton and Barney Harwood want to learn more about the solar system so they challenge scientists Helen Czerski and Jem Stansfield to find out more. They look at how to make telescopes and rockets, and use a toilet roll to measure the distances between planets.

In the Bible, God destroys the sinful cities of Sodom and Gomorrah and sides with Joshua to conquer another misbehaving city: Jericho. Are these stories true or simply moral fables? Archaeological and geological evidence holds the answer.

Over the centuries, explorers traded tales of a lost civilization amid the dense Amazonian rainforest. Scientists dismissed the legends as exaggerations, believing that the rainforest could not sustain such a huge population—until now. A new generation of explorers armed with 21st-century technology has uncovered remarkable evidence that could reinvent our understanding of the Amazon and the indigenous peoples who lived there. Using CGI and dramatic re-creations, National Geographic re-imagines the banks of the Amazon 500 years ago, teeming with inhabitants living in the Lost Cities of the Amazon.

Three billion miles away a grand-piano-sized spacecraft is speeding through the outer solar system at nearly 1,000 miles per minute. After nearly a decade in space, the New Horizons space probe will have just 86 seconds to complete its primary mission: Discover the planet Pluto. This time-sensitive special will showcase the first quality pictures of Pluto that the probe will capture.

It is possible that only one per cent of the wonders of ancient Egypt have been discovered, but now, thanks to a pioneering approach to archaeology, that is about to change. Dr. Sarah Parcak uses satellites to probe beneath the sands, where she has found cities, temples and pyramids. Now, with Dallas Campbell and Liz Bonnin, she heads to Egypt to discover if these magnificent buildings are really there.

Looking at how the Creation stories of the Hopi, Nahua and Maya give them a special connection to maize/corn, synthesized in the statement, “We are corn”. There are many songs, displays and ceremonial practices that affirm this connection. Waaki looks deeper into the world community and how it is connected to maize/corn – what are the interrelationships that exist and celebrates the human capacity for tolerance and compassion in a time when people are becoming more intolerant of difference.

Man has always sought to seek further afield. After the seafaring explorers of the 16th century, 21st century cosmologists today navigate more celestial oceans, with each mission providing an ever-broader and more impressive cartography of our surroundings. At the avant garde of modern technology, these strange travellers are actually immobile, and their vessels are powerful and spectacular telescopes, on the Earth or in space, constantly widening the limits of our knowledge and giving form to our dreams of infinity. From Hawaii to Australia, via South Africa and China, we set out on an incredible scientific and human adventure to visit the planet's greatest cosmic exploration centres to discover the new challenges involved in understanding the universe. A journey on Earth and in the heavens that will take your breath away!

A documentary by husband and wife filmmakers, Mario Balibrera and Dana Evans, of the art colonies of Taos, New Mexico in the early part of the 20th century.

Although the mountain volcano Mauna Kea last erupted around 4,000 years ago, it is still hot today, the center of a burning controversy over whether its summit should be used for astronomical observatories or preserved as a cultural landscape sacred to the Hawaiian people. For five years the documentary production team Nā Maka o ka 'Āina ("the eyes of the land") captured on video the seasonal moods of Mauna Kea's unique 14,000-foot summit, the richly varied ecosystems that extend from sea level to alpine zone, the legends and stories that reveal the mountain's geologic and cultural history, and the political turbulence surrounding the efforts to protect the most significant temple in the islands: the mountain itself.
