From icy worlds with more fresh water than Earth to flying mountains of pure metal, asteroids shaped our past and could shape our future. Could these enigmatic space rocks hold the key to how life arises and is extinguished?

The Earth was formed by a series of cosmic cataclysms, including the most powerful blast in the universe. Could the same chain of events have created other earths elsewhere, inhabited by creatures like us?

How does light escape from the sun? Take a journey from the center of the sun. We witness its fiery birth from in the core, its 430,000 mile battle against gravity and magnetism, and its escape from the solar surface.

The first second of the Universe, the creation of everything when space, time, matter and energy burst into existence. It is the most important second in history, which seals the Universe’s fate and defines everything that comes after - including us.

Saturn’s secrets are out: the ferocious weather, the evolving ring system and the discovery of active geology on Saturn’s moons. Scientists are looking for life on Saturn’s moons -- and they may have found it on Titan.

Asteroids strike, planets collide, black holes blast out death rays, and volcanoes erupt. These are the universe’s weapons of extinction. They’ve happened before, wiping out entire species, and they will happen again.

Beneath the hood of your car lies the history of the universe. The iron in your chassis, the gold in your stereo and the copper in your electronics owe their existence to violent cosmic events that took place billions of years ago.

There is a hellish planet in our solar system, covered in thick dense clouds and roasted by colossal temperatures. Incredibly this is a vision of Earth's future. It's Earth's twin, Venus.

Giant magnetic bubbles millions of miles wide, bizarre invisible matter, and a death star tearing through bands of icy comets, flinging them into violent orbits. All this and more could be inside our cosmic backyard, and effecting our lives on Earth.

We're on the verge of uncovering the how life on Earth came to be. Our origin is a hotly contested scientific debate. Did we come from strange volcanic hatcheries deep under the sea? Or did life on Earth come from another planet?

Our Moon is stranger than you think, and we reveal its incredible secrets. Can we thank the Moon for life on Earth? What explains the mysterious tunnels beneath its surface? Is a lunar base the key to humanity’s future in space?

Where did the Earth's oceans come from? For years, scientists suspected they came from molecules delivered to Earth from distant stars by asteroids, but an exciting new discovery suggests that its true origins are be more exotic than anyone imagined.

There’s a mysterious force you can’t see or touch, but it affects everything in the universe. Magnetism has shaped our cosmos, and without it, Creation would simply disintegrate. We follow scientists trying to understand how this strange force works.

Scientists have discovered a mysterious ninth planet on the very edge of our solar system. Ten times the size of Earth, this strange world could have moons with extraterrestrial life.

Recent discoveries could explain the mystery of how supermassive black holes grow so big. Neither dark matter nor cannibalism can fully explain these monsters, but the latest science might finally provide an answer.

The first close-up images of Pluto revealed unimaginable secrets of the mysterious frozen world. Now, scientists investigate the possibility of a warm ocean of sub-surface water on Pluto, and whether this it could harbor life.
