Europa is a natural satellite of Jupiter, notable for its extremely smooth, icy surface, which is evidence of intense geological processes and potential subsurface liquid water. The physical characteristics suggest a thick, fractured ice crust overlying a global, salty ocean. Tidal forces exerted by Jupiter are thought to generate significant internal heat, maintaining liquid water beneath the icy shell. The interactions between the liquid water and the silicate rock mantle at the bottom of the ocean could potentially facilitate chemical exchanges necessary for the existence of biogenic energy gradients. The body’s composition and extreme tidal environment make it a primary target for the study of habitable extraterrestrial environments.
