New research suggests liquid water is present beneath the south polar ice cap of Mars. Now, a new study argues there needs to be an underground source of heat for liquid water to exist underneath the polar ice cap. The new research does not take sides as to whether the liquid water exists. Instead, the authors suggest recent magmatic activity – the formation of a magma chamber within the past few hundred thousand years – must have occurred underneath the surface of Mars for there to be enough heat to produce liquid water underneath the kilometer-and-a-half thick ice cap...
