Even if we avoid destruction by asteroids, we face eventual melt-down, as our Sun is getting progressively hotter. New Worlds looks at where we could go to escape this fate and talks to scientists who are already exploring how we could turn a planet like Mars into a Noah's ark for the earth's animal and plant life. It may even be that humans have to change themselves genetically to survive.
