This is the greatest story ever told, the creation of everything us. The programme investigates how the Universe came into existence out of nothing, and how it grew from a miniscule point, smaller than an atomic particle, to the vast cosmos we see today.
Black Holes,the most powerful destroyers in the Universe, the most mysterious phenomena in the heavens. For years they were only speculation, now modern astronomy is proving them frighteningly real and showing that they may well shape everything we see.
Galaxies, home to stars, planets and us, come in all shapes and sizes. Witnesses the evolution of galaxies; from clouds of cold gas floating in the voids of space 13 billion years ago, to the magnificent spirals that fill our night sky.
The story of how stars were made by the Universe and how Stars then went on to engineer everything else in that very universe. They changed the Universe by spawning further generations of stars, then planets and eventually the building blocks of life.
There are just eight planets in our solar system, but there could be a hundred billion planets in our Milky Way galaxy alone. This show follows the journey of planets as they grow from grains of dust to the magnificently diverse worlds we see today.
Stars are not eternal; they are dying in unimaginably large explosions called supernovas. Second only to the Big Bang, these explosions are where creation and destruction meet. Only now have we begun to understand how these wonders in our sky work.
Is our solar system unique? Since the first discovery of a planet orbiting another star, some 280 alien solar systems have been identified. It's only by looking at solar systems far beyond our own, that we can understand how remarkable our universe is.
Moons come in every possible shape and size. Home to incredible natural phenomena like gigantic geysers and colossal volcanoes, moons also offer perhaps the best chance of finding alien life in the Universe - and they probably exist in the billions.
Scientists are discovering volcanoes on worlds we once thought dead. From our nearest planetary neighbour to tiny moons billions of miles away, today we are discovering volcanoes on alien worlds. Are these worlds where, tomorrow, we might find life?
Destructive weather forces are symptoms of Earth's creative energy. In our quest to discover if we are alone in the universe, we shouldn't just look for worlds, we should look for weather; find that megastorm, and maybe we will find alien life.
Over the last twenty years we have discovered an extraordinary zoo of planetary nightmares outside our own solar system, all of them truly wild worlds, a collection of monsters. Now we must face the question: Is every planet out there a planet from hell?
The Universe is a magnetic minefield. Spinning star systems crackle and explode, magnetic monsters rip worlds apart, star-quakes shoot beams of devastating energy, and galactic flamethrowers fire gamma-rays half way across the Universe. Will we find Earth in the firing line?
We owe our existence to the stability of earth's orbit. But we are the freaks: everywhere else we look we find orbits are chaotic, unstable, and violent. Yet on the very largest scale, orbits are also a creative force, even constructing the fabric of the universe itself.
We follow the odyssey of a comet as it sails through space, watching every move as it evolves from a chunk of ice and rock into an active nucleus engulfed in a gaseous haze. What we learn is a revelation; comets are even more mysterious than we imagined.
From icy worlds with more fresh water than Earth to flying mountains of pure metal, asteroids shaped our past and promise much for the future. Could these enigmatic space rocks hold the key to how life in the Universe arises and is extinguished?
The Earth was formed by a series of cataclysms without which we would not exist. Could the same events have created other earth-like planets elsewhere in the Universe inhabited by creatures like us?

How and when will the Universe end? Gravity and dark matter are poised to annihilate the Universe in a big crunch. Expansion and dark energy may tear it apart. Or, a phase transition could kill us tomorrow in a cosmic death bubble.
Beneath Jupiter's clouds lie our solar system's deepest secrets: from its violent youth, through the birth of life to the death of the sun. Scientists are discovering that the solar system, the Earth and every living thing exists because of Jupiter.
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 has rewritten the textbooks. 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, 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?
What built the Milky Way? New research might now have the answer, revealing an unlikely hero. At the heart of our galaxy sits a super massive black hole, one of the most destructive objects in the Universe. Could it be our creator?
One day, a cosmic disaster will make life on Earth impossible. To survive, we must find a new home amongst the stars. Scientists are already developing new propulsion systems to take us to these distant worlds.
Is there another Earth out there with liquid oceans, rocky continents and life like us? Astronomers seek the answer with spectroscopy, direct imaging and telescopes. They hope to find evidence of atmospheres, magnetospheres and signs of life.
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 all 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. To understand how our world will be destroyed we need to look at Earth's evil twin Venus.
A look inside the supermassive black hole in the center of the Milky Way to discover terrifying secrets about parallel universes, wormholes, and space-time.

Discovering how life on Earth came to be; the possibility that 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?
