How the Universe Works - Season 3

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.

Examining the ways the unvierse could come to an end.

Beneath Jupiter's clouds lie the solar system's deepest secrets.

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.

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.

Research suggests that a super massive black hole might be the creator of the Milky Way.

Scientists are working on new propulsion systems that would allow travel to distant worlds.

Astronomers search for evidence of another Earth. 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.
