The first map showing the global geology of Saturn's largest moon, Titan, has been completed and fully reveals a dynamic world of dunes, lakes, plains, craters and other terrains. The first map showing the global geology of Saturn's largest moon, Titan, has been completed and fully reveals a dynamic world of dunes, lakes, plains, craters and other terrains. Faculae (bright spots) are named after islands on Earth that are not politically independent. The term "fluctus" refers to flow terrain. In most cases, indications of brightness and darkness refer not to visible light, but to the infrared images used to look through Titan's obscuring haze. [45], Undae are dune fields. On Titan they are named after Greek deities of wind. Titan has an active methane-based hydrologic cycle that has shaped a complex geologic landscape, making its surface one of most geologically diverse in the solar system. You have already liked this page, you can only like it once! The flows represent episodes of activity on the volcano. While Titan’s geology has been mapped before, this is the most comprehensive map of its kind. Note that some features with a physical size given by "diameter" may not be circular and actually refers to its length. Titan, the largest and most complex satellite in the solar system exhibits an organic dominated surface chemistry and shares surface features with other large icy satellites as well as the terrestrial planets. The map indicates that Titan is dominated by sedimentary or depositional processes, ultimately resulting in the large regions of dunes and plains. The new map of Titan highlights relationships between the major geological units, allowing researchers to better understand the processes that have shaped Titan’s surface and how the landscape of has evolved over time. The presence of an atmosphere, initially suggested based on limb darkening by Sola (1904) and later by the presence of methane spectral lines by Kuiper (1944), has long given Titan a special place in the minds of planetary geologists. With a size comparable to that of Mercury, this moon is the only planetary body in our Solar System – besides Earth – known to have stable liquid on its surface. They are named after characters from the Foundation series of science fiction novels by Isaac Asimov. [9], A flumen is a feature that looks like a channel carved by liquid. [16][33], Regiones (regions distinctly different from their surroundings) are named after deities of peace and happiness. The first map of the global geology of Saturn's largest moon, Titan, has been completed, revealing a dynamic world with dunes, lakes, plains, craters and other terrains. [note 1], Albedo features on Titan are named after sacred or enchanted places in world mythologies and literature. [42], Sinus (bays) within seas or lakes are named after terrestrial bays, coves, fjords or inlets. [5], Colles are small hills or knobs which are named after characters in J. R. R. Tolkien's Middle-earth. [43], Terrae are extensive landmasses. But instead of water raining down from clouds and filling lakes and seas as on Earth, what rains down on Titan and fills its liquid pools is methane and ethane. They are named after mythical or imaginary rivers.

The map is in Mollweide projection and has a scale of 1:20,000,000. The first global geologic map of Saturn's largest moon, Titan, is based on radar and visible and infrared images from NASA's Cassini mission, which orbited Saturn from 2004 to 2017.
