A world with an iron core, rocky mantle and enough water on the surface to create liquid water oceans that could support life. (seeker.com)
Heat generated by the gravitational pull of moons formed from massive collisions could extend the lifetimes of liquid water oceans beneath the surface of large icy worlds in our outer solar system, according to new NASA research. (astrobio.net)
The scientists think hydrogen peroxide is an important factor for the habitability of the global liquid water ocean under Europa's icy crust because hydrogen peroxide decays to oxygen when mixed into liquid water. (keckobservatory.org)
