A look at the solar system's largest planet, Jupiter; its formation and composition and its mini-solar system of over 60 moons – some of which may have the potential to support extra-terrestrial life.

Take a tour of the cosmic hot zones--black holes, galaxy mergers, gamma ray bursts and magnetars. Super black holes can literally lasso Earth out of the solar system. A clash between two galaxies can result in a ritual called galactic cannibalism. Magnetars are a cosmic magnetic force so strong it could wipe out data on every credit card.

Have planet hunters finally found proof of other Earth like worlds? Astronomers have now discovered over two hundred alien worlds, beyond our solar system, that were unknown just a decade ago. Discover planets that rage with fiery hurricanes and bizarre planets covered by water so dense that it forms a kind of hot ice. Among these weird worlds, Earth actually seems like the oddball.

Travel from the inner solar system to the Kuiper Belt and explore the moons surrounding the planets of the solar system. Many of these moons that were once unknown are now on the cutting edge of astronomical study. Some burst with volcanic fury another spews icy geysers and others offer the possibility of alien life. Are these strange worlds simply hostile environments unfit for humans or do other possibilities exist? Cutting-edge computer graphics are used to bring the universe down to earth and to imagine what kind of life forms might evolve in alien atmospheres.

Earth’s oceans help make our planet different from every other planet in the solar system. As far as we know, no other place is the right temp for liquid water, the most essential ingredient for life to exist. The oceans are Earth’s primary stabilizing force, and their immense power helps to shape the appearance and behavior of the entire planet and everything living on it. And they are also the planet's great unknown - their deepest points have been visited less than the surface of the moon.

It has taken 4.6 billion years for the Earth to evolve from a barren rock into the world we know today. Explore the forces beyond our planet that have determined Earth’s destiny -- forces of destruction and regeneration in the solar system that created the planet and still protect it. And now the remarkable planet is facing a new challenge: humankind. The question is, how will it survive?
