The Comet

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.

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.

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!

Some 220 miles above Earth lies the International Space Station, a one-of-a-kind outer space laboratory that 16 nations came together to build. Get a behind-the-scenes look at the making of this extraordinary structure in this spectacular IMAX film. Viewers will blast off from Florida's Kennedy Space Center and the Baikonur Cosmodrome in Russia for this incredible journey -- IMAX's first-ever space film. Tom Cruise narrates.

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.

Based on more than two decades of systematic research and cross-cultural comparison by comparative mythologist David Talbott, Remembering the End of the World reconstructs a cosmic drama when planets hung in the sky close to the earth–an epoch of celestial wonder giving way to overwhelming terror. This highly visual presentation offers new answers to enigmas that have baffled experts for centuries. Why did every ancient civilization celebrate a former “Age of the Gods”, an age claimed to have ended in earth threatening disaster? What was meant by the lost “Golden Age?” Why did ancient sky worshipers refer to Saturn as “the sun?” Why was Venus worshiped as the “Mother Goddess?” And why did both Old and New World astronomers celebrate the planet Mars as a great warrior whose battles shook the heavens?

How's it all gonna end? This experience takes us on a journey to the end of time, trillions of years into the future, to discover what the fate of our planet and our universe may ultimately be. We start in 2019 and travel exponentially through time, witnessing the future of Earth, the death of the sun, the end of all stars, proton decay, zombie galaxies, possible future civilizations, exploding black holes, the effects of dark energy, alternate universes, the final fate of the cosmos - to name a few.

This documentary examines theories behind the creation of gamma ray bursts, destructive explosions in space that can wipe out entire star systems.

Discover how the big, bold ideas of Silicon Valley are helping launch a new era of private space exploration in this half-hour KQED Science documentary. From space tourism to mining the moon to companies ferrying NASA astronauts into space, a new wave of commercialization is shaking up the $300-billion global space industry. Meet a new generation of entrepreneurs, sprung from the high-tech culture of Silicon Valley, who are venturing into the new "wild west" of space exploration in search of their space gold. But are there new risks when space is no longer the exclusive domain of big governments?

Kate Humble and Helen Czerski reveal the inner workings of the sun and investigate why scientists think changes in the sun's behaviour may have powerful effects on our climate.

A look at the Sun, the star that revolves at the center of the Solar System, and its representation in art throughout history.

In an age when misinformation, alternative facts, and conspiracy theories have become mainstream, UFOs have risen to become one of the most-talked about pop culture phenomena. With all of this noise, how can we expect anyone to know how much of this is true? What is in our skies? What do we know, and how do we know it? And most importantly: Are we being visited?

Cave paintings and lunar calendars exist in the caves and remains of prehistoric hunters studied recently. What if Prehistoric Man were clever enough to develop in depth scientific knowledge? As unlikely as it may seem, new data tend to prove that Prehistoric Man actually invented Astronomy!

Chaco Canyon, located in northwest New Mexico, is perhaps the only site in the world constructed in an elaborate pattern that mirrors the yearly cycle of the sun and the 19-year cycle of the moon. How did an ancient civilization, with no known written language, arrange its buildings into a virtual celestial calendar, spanning an area roughly the size of Ireland?

The Future of the Planet is at stake by biblical brophecy to spaceborn calamity.
