More episodes from this season
Episode 1: Big Bang
The programme investigates how the Universe came into existence out of nothing, and how it grew from a minuscule point, smaller than an atomic particle, to the vast cosmos we see today.
Episode 5: Supernovas
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.
Episode 6: Planets
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.
Episode 7: Solar Systems
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.
Episode 8: Moons
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.
