More planets could host alien life
LONDON: There could be many more habitable planets in the universe than previously thought, suggest new computer models. It is believed that for water to exist in its life-giving liquid form, a planet had to be at the right distance from its sun - in the habitable zone. But a new model allows scientists to identify planets with underground water kept liquid by planetary heat, the BBC reported. "It's the idea of a range of distances from a star within which the surface of an Earth-like planet is not too hot or too cold for water to be liquid," explained Sean McMahon, the PhD student from Aberdeen University who is carrying out the work.
