Smashed Icy Moons Cool Too Rapidly to Retain Oceans
A Universe Today report examines how impacts involving icy moons could affect the formation or survival of subsurface oceans. The question is relevant to moons such as Jupiter’s Europa and Ganymede and Saturn’s Enceladus, which are of scientific interest because oceans beneath their icy crusts could potentially support life as we know it.
Some icy moons in the Solar System contain oceans beneath their frozen crusts, including Jupiter’s Europa and Ganymede and Saturn’s Enceladus. These moons are of scientific interest because such environments could potentially host life as we know it.
A report by Universe Today examines processes that may produce subsurface oceans or prevent them from forming. It focuses on the possibility that icy moons disrupted by impacts could cool too quickly to retain oceans.
THE QUESTIONS THIS EVENT LEAVES BEHIND
What impact conditions would determine whether an icy moon retains or loses a subsurface ocean?
How much evidence exists that collisions have affected the interiors of icy moons?
Could rapid cooling change how scientists assess the habitability of icy moons?
What observations would distinguish an ocean that never formed from one that later disappeared?
