Even if the surface has ice, there could be liquid water and living organisms underneath.
We might not be alone in the universe. Actually, it may be confirmed as a very crowded place by new computer models developed to help identify habitable planets.
Estimates of places that can sustain life have been based on the likelihood of them having surface water. But software recently developed by the Aberdeen University allows researchers to identify planets with underground water kept liquid by planetary heat.
Water is fundamental for life and planets too close to the sun lose water to the atmosphere through evaporation. On the other hand, planets located in distant reaches from their star have their surface water locked away as ice.
