A users' guide to the cosmos, from the Big Bang to galaxies, stars, planets and moons: where did it all come from and how does it all fit together? A primer for anyone who has ever looked up at the night sky and wondered.
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.
How does light escape from the sun? We take a journey from the centre of the sun, following the path of light. 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.
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.
Huge magnetic bubbles millions of miles wide; strange invisible matter, and a death star tearing through bands of icy comets, flinging them into violent orbits.
