How the Universe Works - Season 4

The history of the Universe lies beneath the hood of your car. 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.

Discovering how life on Earth came to be; the possibility that life on Earth came 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? The incredible secrets of the moon are revealed; the moon might be responsible for life on Earth.

For years, scientists suspected that the oceans came from molecules delivered to Earth from distant stars by asteroids, but a new discovery suggests that their true origins may be more exotic.

Scientists attempt to understand how this strange force of magnetism works.
