Surface, ocean and core of Saturn’s moon Enceladus. The illustration shows the ice shell, which is thinner at the polar regions, with the ocean underneath. The core of Enceladus is assumed to be porous and thus permeable to ocean water. The graphic is based on a new model used to produce a three-dimensional simulation of these processes under the influence of Saturn’s tidal forces. The orange “glowing” parts of the core represent the areas that reach temperatures of at least 90 degrees Celsius.

Structure of the hollow Eu(III)-benzoate nanotubes. a) SEM image; scale bar = 400 nm. b) TEM image; scale bar = 100 nm. A magnified image is given in Figure S2 in the Supporting Information. c) PXRD data. (‘) indicates signals corresponding to the lamellar substructure. Black curve = experiment pattern obtained from the hybrid material. Blue curve = simulated pattern with the structure model presented in (d). Blue = Eu; red = oxygen; dark gray = carbon; light gray = hydrogen; yellow = cell edges of monoclinic Eu2O3.
