Earth expected to be habitable for another 1.75 billion years

Habitable conditions on Earth will be possible for at least another 1.75 billion years – according to astrobiologists. "If we ever needed to move to another planet, Mars is probably our best bet. It's very close and will remain in the habitable zone until the end of the Sun's lifetime -- six billion years from now," one of the researchers said.
