New research suggests icy moons in the outer solar system could retain their subsurface oceans even if they are shattered by large impacts, with fragments potentially holding on to liquid water. The finding has implications for the search for life, as it widens the range of places where habitable conditions might survive dramatic collisions and reassembling events over billions of years.
