If life on Earth isn't doing it for you, then there's good news - an alternative may be around the corner. As German scientists announce that theoretical "Super-Earths" - planets 10 times the size of Earth with similar atmospheres - could support life for 35 per cent longer than our home planet, NASA scientists have discovered 55 Cancri f - a planet 45 times the size of Earth in a distant solar system that

spend[s] its entire orbit within what astronomers call the "habitable zone". The zone marks a "Goldilocks" band of space where the heat from a star leaves a planet neither too hot nor too cold to support liquid water, which is believed to be crucial for life.
