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.
Journal ArticleDOI

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.
Journal ArticleDOI

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.
Journal ArticleDOI
Subsurface properties and early activity of comet 67P/Churyumov-Gerasimenko
Samuel Gulkis,Mark Allen,Paul von Allmen,Gerard Beaudin,Nicolas Biver,Dominique Bockelée-Morvan,Mathieu Choukroun,Jacques Crovisier,Björn Davidsson,Pierre Encrenaz,Thérèse Encrenaz,Margaret A.

TL;DR: Subsurface temperatures showed seasonal and diurnal variations, which indicated that the submillimeter radiation originated at depths comparable to the diurnal thermal skin depth of comet 67P/Churyumov-Gerasimenko.
Journal ArticleDOI

TL;DR: The Cassini Titan Radar Mapper obtained Synthetic Aperture Radar images of Titan's surface during four fly-bys during the mission's first year as mentioned in this paper, showing evidence of major planetary geologic processes, including cryovolcanism.
