Titan-PIA12695.jpgThe strange Atmosphere of Titan (possible True Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)73 visiteCaption NASA:"The Cassini Spacecraft examines the characteristics of Titan's Atmosphere as it peers at Saturn's largest moon using a filter sensitive to Visible Violet Light.
This image shows Atmospheric Banding around Titan's North Pole and reveals hints of the moon's seasonal Hemispheric Dichotomy near the Equator. (to learn more about the Northern Bands, please refer to images PIA08868 and PIA08928).
This view looks toward the anti-Saturn side of Titan. North on Titan is up and rotated 23° to the left.
The image was taken in Visible Violet Light with the Cassini Spacecraft wide-angle camera on June 21, 2010. The view was obtained at a distance of approx. 170.000 Km (about 106.000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 33°.
Image scale is roughly 10 Km (about 6,2 miles) per pixel".MareKromiumAgo 25, 2010

Titan-Lakes-Ontario_Lacus-00-PIA13172.jpgOntario Lacus68 visiteThis image of Ontario Lacus, the largest lake on the Southern Hemisphere of Saturn's moon Titan, was obtained by NASA's Cassini Spacecraft on Jan. 12, 2010.
North is up in this image. Objects appear bright in this radar image when they are tilted toward the Spacecraft or have rough surfaces. The lake surface appears dark because it is smooth. The Northern Shoreline features flooded River Valleys and Hills as high as about 1 Km (3000 feet).
A smooth, wave-sculpted Shoreline, like that seen on the S/Eastern side of Lake Michigan, can here be seen on the N/Eastern side of the lake.
Smooth lines parallel to the current shoreline could be formed by low waves over time, which were likely driven by winds sweeping in from the West or South-West.
The S/Eastern shore features a round-headed Bay intruding into the shore. The liquid-filled depressions appear to be relatively recent.
The middle part of the Western Shoreline shows the first well-developed Delta observed on Titan. The shape of the Delta shows that liquid flowing down from a higher plain has switched Channels on its way into the Lake, forming at least two lobes. Examples of this kind of Channel switching and wave-modified deltas can be found on Earth at the Southern end of Lake Albert between Uganda and the Democratic Republic of Congo in Africa and the remains of an ancient lake known as Megachad in the African country Chad.
Titan is the only other world in our Solar System known to have standing bodies of liquid on its Surface. Because Surface temperatures at the Poles average a chilly 90 Kelvin (about minus 300 degrees Fahrenheit), the liquid is a combination of Methane, Ethane and Propane, rather than water.
Ontario Lacus has a surface area of about 15.000 square Km (approx. 6000 square miles), slightly smaller than its terrestrial namesake, Lake Ontario.MareKromiumLug 16, 2010

Titan-Lakes-Ontario_Lacus-01-PIA13173.jpgOntario Lacus54 visiteThis is Ontario Lacus, the largest lake on the Southern Hemisphere of Saturn's moon Titan. It is based on overlapping radar images obtained by NASA's Cassini Spacecraft on June 22, 2009, July 8, 2009 and Jan. 12, 2010. The images were synthesized into stereoscopic images by the Cassini radar team.
The Northern Shoreline features low Hills, probably about 1 Km (3000 feet) in altitude, and flooded River Valleys. A smooth, wave-sculpted Shoreline, like that seen on the South-Eastern side of Lake Michigan, can be seen on the North-Eastern side of the Lake.
The South-Eastern shore features a round-headed bay intruding into the shore. The middle part of the Western Shoreline shows the first well-developed delta observed on Titan.
Topography has been vertically exaggerated by a factor of roughly 10 times. Titan's solid Surface and Atmosphere are portrayed in shades of brown, approximating their appearance as measured by the descent imager and spectral radiometer on board the Huygens probe, which landed on Titan in 2005. Scientists surmise the liquid Methane, ethane and propane in the lake would look black to the human eye, but this is a hypothesis based on the best available data.
The Sun was placed low on the horizon, at an angle similar to where it was during the Cassini Fly-Bys.MareKromiumLug 16, 2010

Titan-PIA12664.jpgTitanian "Aura" (Natural - but enhanced - Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)53 visiteCaption NASA:"Sunlight scattering through the periphery of Titan's Atmosphere reaches Cassini as the Spacecraft's camera is pointed at the dark side of the Planet. A detached, high-altitude global haze layer encircles the Planet. This view looks toward the Leading Hemisphere of Titan. North on Titan is up.
The image was taken with the Cassini Spacecraft narrow-angle camera on April 2, 2010 using a spectral filter sensitive to wavelengths of UltraViolet Light centered at 338 nanometers. The view was acquired at a distance of approx. 1,5 MKM (about 932.000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 153°.
Image scale is roughly 9 Km (about 5,7 miles) per pixel".MareKromiumGiu 29, 2010
