The author concludes that there must be a lake of liquid water between Enceladus’s rocky core and icy surface. This is because a space probe discovered something denser than ice between the core and the surface, and that denser substance can only be liquid water.
The conclusion is the assertion that there’s a lake of liquid water between Enceladus’s rocky core and icy surface: “Between these two layers, there must be a lake of liquid water.”
