" The actual HZ lifetime of any given planet is unlikely to be controlled solely by planetary surface temperatures, and individual worlds may experience a variety of divergent (bio)geochemical evolutionary histories, possibly resulting in markedly different planetary environments to that of Earth." First step it may be, it's still a fascinating one. As the models for habitability get further defined, that may help astronomers find another planet with life that much sooner. Additionally, this research reminds us that though the end may be billions of years away, the ability of the Earth to remain home for human beings won't last forever. But if humans are still around when the Earth begins to move out of the habitable zone, we can always move next door. "If we ever needed to move to another planet, Mars is probably our best bet," lead researcher Andrew Rushby said in a statement. " It’s very close and will remain in the habitable zone until the end of the Sun’s lifetime - six billion years from now." Follow me on Twitter or Facebook. Read my Forbes blog here.
