(Phys.org) —In 2 billion years' time, life on Earth will be confined to pockets of liquid water deep underground, according to PhD astrobiologist Jack O'Malley James of the University of St Andrews. The new research also suggests that though the hardiest forms of life may have a foothold on similar worlds in orbit around other stars, evidence for it may be very subtle. O' Malley- James will present the findings at the National Astronomy Meeting in St Andrews, Scotland.
