Space - Episode Guide

Sam Neill explores the wonders and terrors of the Universe - and discovers that human beings may all come from outer space. Every atom that we are made of was created billions of years ago in the hearts of exploding stars - and even the spark of life may have been carried to Earth inside a comet. On a journey from the Big Bang to the living things we see around us today, Sam shows how we came to be here - because of what happened out in space.

Sam Neill takes us on a rollercoaster ride through the galaxy to discover how disasters in space regularly threaten our entire world. We go back to the very earliest days of our planet to see why we are lucky life ever got started, and we learn just what will happen if a massive asteroid ends up on a collision course with Earth.

Sam Neill transports us into the murky and terrifying world of the universe's ultimate monster - the black hole. They are only ten miles across, but they can rip apart a star of a million miles or more. Black holes are gravity gone mad. There should be ten million of them in our galaxy - but we have only found two hundred of them. So are black holes any threat to us here on Earth? Sam's voyage of discovery ends with a look at what would happen if our planet even encountered one of these interstellar destroyers.

Mars is the favourite when it comes to deciding where humans might live once the earth becomes uninhabitable.
