Europan lenticulae
Europan lenticulae Jason Perry's version of the Galileo mosaic "19ESRHADAM01," captured on Europa on February 1, 1999. NASA / JPL / UA / Jason Perry

The mosaic had been intended to cover Rhadamanthys Linea, but the frames fell slightly off target so that only their southern corners overlapped the linear feature. Instead, the mosaic covered a region covered with lenticulae, features that are interpreted to result from convection within Europa's solid ice shell.
