If We Had No Moon:
Without the moon, we wouldn't exist. Life, if it had started at all, would be in the earliest stages of evolution. Days would last four hours, winds would blow at hurricane-force and there'd be a dense and toxic atmosphere resembling the runaway greenhouse effect of hell-like Venus. What luck that 50 million years after the formation of the solar system, our proto-planet is smacked by a planetesimals more than twice the size of Mars. From that mother-of-all impacts is born the Moon. It is born in less than a year from debris blasted into orbit — an enormous object in the sky, just 14 thousand miles away, 17 times closer than today. What was the earth like before this? What would the earth be like if the moon went away? What would it be like, "If We Had No Moon?"
What Lies Below:
"What Lies Below" centers around a young female team of cave explorers that will travel to any location on the planet Earth to passionately explore and document the millions of uncharted miles of caves that rest beneath our feet, much of which has never been seen or tread on by mankind. Each member of our team comes with a specialty that will be used to make scientific discoveries, map uncharted territories, discover new species of animal life, and uncover fantastic wonders never before seen. Our team leader and expert caver is Nancy Aulenbach, who says her first caving experience was in-utero, while still in her mother's womb and has not stopped since. She will lead biologist Dr. Jean Krejca, and geologist Andrea Croskrey MSc, who are all renowned experts in the field of cave exploration.
The team will travel to the most magical and dramatic environments in the world. They will uncover the history, the lore, and dangers of the location as well as the indigenous cultures of each country they visit. Together they will then descend the dangerous deep, cold, and dark world of subterranean Earth where endless mysteries abound. From deep ocean grottos, lava tubes, glacier caves, thermal oven-like caverns, edible cave walls, bottomless ice crevasses, and endless mile deep maze like corridors, that push every primal fear and phobia we've come to dread. This is a world that with one wrong move, the pitch black and silent labyrinth will swallow even the most experienced caver, sometimes never to be seen again.
The team will encounter millions of bats, bugs, and animal life, 60 ft tall redwood sized crystals, prehistoric cave paintings and bones, massive underground lakes, rivers, and more. Viewers will watch as these women venture through horizontal, vertical and terrestrial caves; weave their way through tiny passages, swim through flooded underground vaults, drop into amazing blue labyrinths of ice and enter a whole new world that most people don't know about and have never seen — until now. These finds are just the starting point in this breathtaking and crisply shot HD series, where our female team will bond, live together, explore, discover, and deliver viewers a world yet unseen and as mysterious as a journey into the far reaches of space.
4.56 billion years ago, a planet the size of Mars collided with our Earth. It set off a chain of events that would transform the Earth from a lifeless wasteland into the fertile, blue planet we know today. This is that story. Our intrepid team of scientists gets hands-on with the evidence to find out how volcanic eruptions, collisions with comets and the unstoppable drift of the continents across the globe have combined to push up some of the most spectacular landscapes in the world. In this epic tale, we shall learn how life has survived catastrophe after catastrophe to emerge ever stronger in a constantly changing world.
Inside Planet Earth:
Humans have explored the moon a quarter million miles away, yet more than 99 percent of Earth remains unexplored. But this final frontier isn't on the surface of the Earth. Below the rain forests and the mountains are thousands of miles of inaccessible rock and metal, searing heat, and crushing pressure. But what if a crack could be opened all the way to the center of the Earth? The Earth is like an onion, divided into layers. Each layer plays a vital role in making the world a place where life can survive. Above Ground: The outermost layer, the atmosphere, is painfully thin. It makes up just one percent of the volume of the planet. The journey begins by discovering what it's like to free-fall through 19 miles of atmosphere — a feat accomplished by American legend Joe Kittinger in the 1960s.
- Ground Level: Plunging through the crust, discover how the Earth's inner heat breaks up this layer into multiple continental rafts, the tectonic plates.
- 1000 Feet Inside Earth: Broken strata and faulted layers created by the process of mountain building. See the awe inspiring effect of underground erosion inside the spectacular Carlsbad Caverns.
- 1.5 Miles Inside Earth: Float past seams of coal to understand the role the crust plays in conserving life on Earth. The crust is a vast reservoir of carbon. At Georgia's Okefenokee Swamp discover how coal is made.
- 2.5 Miles Inside Earth: Find gold in the deep-level mines of South Africa and discover life that can exist up to 7 miles inside Earth, surviving radiation and 130 degree heat, and living on nothing more than iron.
- 20 Miles Inside Earth: Glowing seams of red rock, pure iron ore, laid down in massive volumes by early photosynthesizing bacteria.
- 30 Miles Inside Earth: Cross the Moho, the boundary layer between crust and mantle. Discover the significance of this bizarre fudge-like layer and how it acts like a lubrication layer for plate tectonics. Walk along a beach made of Moho in Cornwall, England.
- 100 Miles Inside Earth: Dive deep into the mantle, full of convecting magma and diamond caverns.
- 1500 Miles Inside Earth: Find a place populated by awesome chemical horizons and magnificent mantle plumes 2000 mile high.
- 2000 Miles Inside Earth: Cross into the Core to discover how this moon-sized sphere of molten iron is the Earth's Great Magnet, generating a magnetic field that keeps humans safe from the lethal radiation of space...or is it? Evidence suggests the magnetic field is experiencing a significant wobble and could even be in the early stages of shut down. Mars and its history suggest what Earth would be like if the magnetosphere vanished.
- 3100 Miles Inside Earth: Underground metallic forests growing on the Inner Core, potted divots, and vast subterranean mountains.
- 3981 Miles Inside Earth: The Center of the Earth, where gravity is absent...
Nothing less than all life on earth gets its energy from the rays of the sun. Our very existence relies on the Sun's unique size, temperature, and location. Yet, with so much depending on it, you'd think we'd have a better understanding of this, our planet nearest star. The truth is that the Sun is still a mystery — one that has always driven, and continues to drive, scientific inquiry and ingenuity. Why, against logic, is the sun atmosphere hotter than its surface? Why does its magnetic field reverse every 11 years? Why do the thousands of violent eruptions on its surface virtually and suddenly stop like clockwork every 70 years? And what will happen to Earth in 5 billion years when the sun consumes all its fuel, and burns out?
In this hour, we'll take a journey to the Sun using the latest technology, advances in astronomy, and cutting edge CGI. We'll ask scientists and experts to explain its mysteries and help us to understand the massive opposing forces of nature that hold it together. We'll see how it was born, exists today and finally, how our world will end when THE SUN consumes us all.
Faces of Earth (Building The Planet):
From the Pacific Northwest to the shores of the Atlantic seaboard, the breadth and scope of America is like no other place on Earth. The land we see today was shaped over hundreds of millions of years. Guided by leading geoscientists, and with the aid of dramatic special effects and animations, we unravel the mysteries of continent-building and the almost unimaginable span of geologic time. Using high tech science tools and even Ultralight aircraft, viewers will travel with geoscientists as we discover America's prominent geologic features and how they formed.
Sunrise Earth (Ep. 18: Edge of the Atlantic):
Coast Guard Beach, Cape Cod National Seashore, Massachusetts. From the place where the Mayflower made her first landfall in the New World, we stand at the beginning of what Henry David Thoreau called "The Great Beach." Here along the backside of Cape Cod, the sun's orb rises directly over an endless Atlantic Ocean swell. But not today, a day when the vestige of a fierce Atlantic storm sends a crashing surf onto the beach. Waves, wind, and sand dance together, alternately eroding the coastline and building the dunes back up. Shorebirds, seals, a lone surfer, and distant surfcasting fishermen search frigid waters for fish, as waves pound the shoreline slope.
