Surface of Triton

This beautiful image of Triton reveals many interesting features of its surface. The surface of Triton is halfway between Ganymede's and Europa's (two of Jupiter's moons).

Ancient portions of the surface have many craters, and newer portions smooth, or have grooves. The different ages may indicate the presence of active processes in the inside.

Fancy image processing has revealed what it may look like to practically be standing on the surface of Triton.
