Icy & Fluvial Features

The strange, dimpled surface of Neptune's moon Triton, resembling the skin of a cantaloupe — a young, resurfaced landscape unlike anywhere else, imaged by Voyager 2.

A region of Europa where the icy crust has broken into a jumble of tilted blocks 'rafts' set in refrozen slush — evidence that the surface interacts with the ocean below.

The largest known sea of liquid methane and ethane on Titan, near the north pole — the largest body of surface liquid in the Solar System beyond Earth.

The largest lake in Titan's southern hemisphere, a shallow methane-ethane lake whose shoreline changes with the moon's seasons.

The vast nitrogen-ice plain that forms the western lobe of Pluto's bright 'heart'. Its ice slowly churns in convection cells and flows like a glacier, keeping the surface young.

A crater that once held a lake, with a well-preserved river delta at its rim. The Perseverance rover is caching samples here in the search for signs of ancient life.

One of the largest outflow channels on Mars, carved by catastrophic floods of water that burst from the Tharsis region billions of years ago.
