How the Universe Works

Life & Death On The Red Planet. Once there was life on Mars - but scientists believe a series of devastating mass extinctions transformed a watery planet into a desert.

About the programme: How the Universe Works 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.
