In the vast expanse of our Solar System, amidst the rings and moons of Saturn, a small celestial body harbors a profound secret: Mimas, one of Saturn’s smallest moons, hides beneath its cratered exterior a vast, global ocean of liquid water. This revelation, spearheaded by Dr. Valéry Lainey of the Observatoire de Paris-PSL and unveiled in the renowned pages of Nature, not only reshapes our understanding of Mimas but also ignites speculation about the potential for life beyond Earth. The discovery of this youthful ocean, believed to have formed a mere 5 to 15 million years ago, casts Mimas in a new light, positioning it as a captivating enigma awaiting further exploration and investigation.
