TL;DR: These northern-hemisphere lakes constitute the strongest evidence yet that a condensable-liquid hydrological cycle is active in Titan’s surface and atmosphere, in which the lakes are filled through rainfall and/or intersection with the subsurface ‘liquid methane’ table.

TL;DR: The most recent Cassini RADAR images of Titan show widespread regions that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth, and the distribution and orientation of the dunes support a model of fluctuating surface winds.

TL;DR: Hayes et al. as discussed by the authors used Huygens probe observations to derive the timescales for flow into and out of observed lakes, similar to seasonal cycles, and compared the time between collocated SAR observations in order to considertheroleofsubsurfacetransportinTitan’shydrologic cycle.

TL;DR: The Cassini Titan Radar Mapper imaged about 1% of Titan's surface at a resolution of ∼0.5 kilometer, and larger areas of the globe in lower resolution modes, revealing a complex surface, with areas of low relief and a variety of geologic features suggestive of dome-like volcanic constructs, flows, and sinuous channels.

TL;DR: In this article, a large number of longitudinal dunes have been discovered by the Titan Radar Mapper on the surface of Titan and they are found mainly within ±30° of the equator in optically-, near-infrared-, and radar-dark regions, indicating a strong proportion of organics.
