At 4.6 billion years old, the Solar System is our solid, secure home in the Universe. But how did it come to be? In this episode we trace the system's birth from a thin cloud of dust and gas. Shocked by a nearby supernova, the pull of gravity and natural rotation spun it into a flat disc from which the Sun and planets coalesced. It all happened in the space of 700 million years, during which the planets jockeyed for position, dodging the Late Heavy Bombardment of deadly asteroids and setting into the neat, stable system that we now realize might be a rarity in the universe.

The computer animated drama takes place on Darwin IV, a planet 6.5 light years from earth, with 2 suns and 60% of Earth's gravity. Earth sends a pilot mission with three probes. This robotic fleet is responsible for finding and assessing any life forms on Darwin IV. The probes soon find themselves in the middle of a developed ecosystem teeming with diversity of life of all sizes. "Alien Planet" is motivated by real science missions, such as the NASA Origins Program and the NASA / JPL Planet-Finder Mission, as well as the European Space Agency's Darwin Project. It is a cosmic expedition along side Stephen Hawking, Michio Kaku, Jack Horner, Craig Venter, and George Lucas, and NASA's Chief Scientist Jim Garvin. No longer just the domain of science fiction, "Alien Planet" dramatizes an exciting and possible answer to what alien life really looks like and when we'll find it.

It was 1985. Guns N' Roses were soon to be known as the last mammoth rock entity to come out of LA after selling over 100 million albums. Jon Brewer brings alive never-before-seen video footage of Guns N' Roses in their earliest days as a fledgling band, filmed and meticulously archived over the years by their close friend. They became known as 'the most dangerous band in the world' and retained the title for reasons this film portrays, via interviews with band members and those who were there on, and off, tour. Venture down seedy Sunset Strip to the Whiskey, the Rainbow and the Roxy, all known as 'the Jungle'.

Head beyond the Asteroid Belt for an out of this world experience. Welcome to Jupiter, home of high adrenaline adventure. Plunge into its mysterious depths. When you drop through the clouds it would get darker and hotter. At the center the temperatures are hotter than the surface of the sun and the pressures are unimaginably high.

The most famous – and perhaps most misunderstood – episodes in the epic history of the Holy Wars that are known to history as The Crusades – the clash between Richard the Lionheart and Saladin. In July 1192, Richard the Lionheart stood poised for a strike on Jerusalem, while Saladin – mighty sultan of Islam – readied his troops inside the city, preparing for the inevitable attack. During a year-long campaign across Palestine, these two legendary leaders had fought each other to a stand-still. Thousands had perished, appalling atrocities had been perpetrated on both sides. And now they faced each other in a battle for their sacred objective.

Scientists investigate the way the Sun builds its power -- through fusion -- hoping to find a way to use fusion as a less dangerous and less radioactive waste-producing path to energy than fission. But there are some major difficulties along the way. Fusion really is the perfect way to make energy. We have millions of years worth of fuel. It produces no long-lived radioactive waste. If we can solve the engineering challenges, energy will become cheaper, more available for everybody.
