The result: magnesium-rich phyllosilicates \u2013 clay minerals that only form on contact with liquid water. Surprisingly, no water ice is detectable on the moons themselves. And such minerals had never before been found in the outer solar system beyond Jupiter.<\/p><div id=\"netgu-2131281072\" class=\"netgu-content netgu-entity-placement\"><aside class=\"deals-top
