SURFACE FEATURES GALORE
Titan has an active surface with
dunes, lakes and even (potentially)
cryovolcanoes. Shown clockwise from
top right are a colourised version of
the pebbled surface Huygens landed
on; a 3D radar map of Doom Mons
(tallest peak) and its nearby pit Sotra
Patera (vertical height exaggerated
by a factor of 10); a slice of the dunes
of Shangri-la; Ligeia Mare and its
channel systems in false colour; and a
global image combining infrared and
visible-light data to reveal the surface:
