An article published in the journal “Nature Astronomy” describes a research that presents a possible explanation for the long-term existence of hydrothermal activities and an underground ocean of liquid water on Enceladus, one of Saturn’s moons. A team of researchers led by GaĆ«l Choblet of the University of Nantes in France analyzed data collected by the Cassini space probe concluding that a porous core can be a key factor in generating heat for billions of years supporting an environment potentially favorable to life.
