Professor Stephen Hawking believes that the Earth is under threat… and that the only way to safeguard the future of the human species is to make a new home on another planet.  

In LEAVING EARTH: OR HOW TO COLONIZE A PLANET we travel the globe and interrogate the latest science to investigate whether we really have what it takes to colonise another world. Is there another planet out there that would support us? How will we get there? And how will we set up a new human civilization on an alien world?
