Liquid lakes close to moon's skin
Scientists have found the best evidence yet for water just beneath the surface of Jupiter's icy moon, Europa.
Analysis of the moon's surface suggests plumes of warmer water well up beneath its icy shell, melting and fracturing the outer layers.
The results, published in the journal Nature, predict that small lakes exist only 3km below the crust. Any liquid water could represent a potential habitat for life.
From models of magnetic forces, and images of its surface, scientists have long suspected that a giant ocean, roughly 160km (100 miles) deep, lies somewhere between 10-30km beneath the ice crust.
