Taking into account the dwarf planet's size and interior heat flow, which is around two percent that of Earth's, the team discovered that the temperatures and pressures at play below Sputnik Planitia could give rise to a viscous, slushy subsurface ocean of water ice.

If this is the case, we might also find Europan planets with an abundance of subsurface oxygenated water, which could bubble out to form habitable caves in the ice above a cold ocean.
