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.

NASA’s next era will be its greatest yet. That is the clear 'roadmap' painted by Journey To Space. The film absolutely annihilates the perception that the space program died with the end of the Space Shuttle Program by showcasing the exciting plans NASA and the space community are working on, and the challenges they must overcome to carry out audacious missions such as landing astronauts on Mars and capturing asteroids. In the past half century, humans have punched through the stratosphere, walked on the moon, and lived continuously in orbit. In the coming decades, our unquenchable curiosity will take our species beyond the cradle of Earth to touch the face of another world. Strap in for the next giant leap. Next stop ... Mars!

Take a tour through the Art Gallery of the Galaxy and view what are considered the "crown jewels" of the heavens. Nebulas are mysterious clouds of gas that aren't classified as stars, planets, moons or asteroids. Astronomers use the most sophisticated techniques to view them since they are practically invisible to the naked eye. Nothing less than stunning, nebulas glow, reflect or obscure the galaxy's light with amazing swirls of color. Nebulas mark the regions where the nothingness of space first coalesces, where stars are born and where stars die. Cutting-edge computer graphics are used to bring the universe down to earth.

The mission of NASA's Osiris-Rex is to intercept a giant space rock and crack the mysteries of a potential killer asteroid. Can it unlock how asteroids kick-start life on Earth and reveal why they might be our ticket to other worlds? To find out, we take a ride with one of NASA's most ambitious missions to investigate a space rock in more detail than ever before, to reveal how asteroids will rewrite the past and forge the future of our solar system.

Find out what is being done to prevent the end of the world from threats from outer space such as comets and asteroids. Also discussed are apocalyptic scenarios.

Asteroids strike, planets collide, black holes blast out death rays, volcanoes erupt and ice engulfs the planet. These are the universe's weapons of extinction. They've happened before - wiping out entire species, and they will happen again. Are we next?
