Titan-PIA09846-PCF-LXTT-IPF.jpgTitanian Clouds and Surface Features (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)66 visiteA bright streak of whitish Clouds graces the Northern Skies of the Saturnian moon Titan and this was the second time that the NASA - Cassini Spacecraft's imaging cameras spotted clouds at apporx. 60° of North Latitude (the previous occasion occurred during the observations that were carried out in the month of February of the AD 2007: observations which also led the cameras of the Spacecraft to spot the Dark Lakes - likely filled by Liquid Hydrocarbons - that cover much of the Northern Regions of this fascinating moon). The almost circular, and approx. 400-Kilometer wide Impact Crater Menrva can be seen near center, a little to the left of the Terminator. North on Titan (which, we remind you, is approx. 5150 Km - such about 3200 miles across) is up and rotated 26° to the right.
The image was taken with the NASA - Cassini Spacecraft Narrow-Angle Camera on January 20, 2008, using a combination of Spectral Filters sensitive to Wavelengths of Polarized InfraRed Light centered at 938 and 746 nanometers. The view was acquired at a distance of approximately 1,3 MKM (---> Million KiloMeters), such as about 800.000 miles from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 58°. Image scale is roughly 8 Km (a little more than 5 miles) per pixel. However, it has to be noted that, due to the scattering of light that is caused by the Titanian Hazy Atmosphere, the size of the Surface Features that can be seen and resolved, is a few times larger than the actual (and aforementioned) pixel scale.
This frame (which is an Original NASA - Cassini Spacecraft image published on the NASA - Planetary Photojournal with the ID n. PIA 09846) has been additionally processed and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Cassini Spacecraft and then looked outside, towards the Saturnian moon Titan), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among others, the existence of different Elements present in the Atmosphere and Surface - where visible - of Titan, each having a different Albedo (---> Reflectivity) and Chemical Composition.

Titan-PIA09846.jpgAlien Weather (False Colors; credits: Lunexit)102 visiteA bright streak of cloud graces the Northern Skies of Titan.
This is the second time the Cassini spacecraft's imaging cameras have spotted clouds at 60° North Latitude on Titan - the previous occasion being the Feb. 2007 observations during which the cameras saw the dark, hydrocarbon lakes that cover much of the North.
That cloud feature is visible at the bottom of the still image in Exploring the Wetlands of Titan. The circular, 400-Km wide impact feature Menrva can be seen near center.
North on Titan is up and rotated 26° to the right.
The image was taken with the Cassini spacecraft narrow-angle camera on Jan. 20, 2008 using a combination of spectral filters sensitive to wavelengths of polarized infrared light centered at 938 and 746 nanometers. The view was acquired at a distance of approx. 1,3 MKM (800.000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 58°. Image scale is roughly 8 Km per pixel. Due to scattering of light by Titan's hazy atmosphere, the sizes of surface features that can be resolved are a few times larger than the actual pixel scale".MareKromium

Titan-PIA10243.jpgUnder the Fog...103 visiteCaption NASA:"This graphic depicts a cross-section of the Saturnian moon Titan. Cassini scientists speculate there may be a layer of liquid water mixed with ammonia about 100 Km (approx. 62 miles) below the surface of Titan.
The assumption that Titan contains an internal ocean was generated from data gleaned from Cassini's Synthetic Aperture Radar during 19 separate passes over Titan between October 2005 and May 2007. Using data from the radar’s early observations, the scientists and radar engineers established the locations of 50 unique landmarks on Titan's surface. They then searched for these same lakes, canyons and mountains in the reams of data returned by Cassini in its later flybys of Titan. What they found was prominent surface features seemed to shift from their expected positions by up to 31 Km (about 19 miles). Since the features could not have really moved, the apparent shift told the scientists and engineers that Titan was spinning about its axis in a previously unsuspected manner. The pre-Cassini model of Titan's spin accounted for the gravitational fields of Saturn and other nearby planets and moons but omitted other smaller less well understood effects. Since the observed spin of Titan does not fit this model, other influences, such as the seasonal changes in the motion of its atmosphere must also be important. It is difficult to explain how such relatively low energy phenomena could have such a pronounced influence on Titan's spin unless the moon's icy crust was decoupled from its core by an internal ocean. If the crust were decoupled from the core, atmospheric fluctuation alone could account the observed spin".MareKromium

Titan-PIA10418.jpg"Banded" Planet83 visiteCaption NASA:"This Cassini Spacecraft view of Titan shows banding in the Atmosphere of the moon's Northern Hemisphere. Like the planet Venus, Titan's atmosphere rotates faster than its surface, a characteristic called "Super-Rotation."
North on Titan is up.
White specks seen on Titan are artifacts of the process used to enhance features in the moon's Atmosphere. The image was taken in visible blue light with the Cassini Spacecraft wide-angle camera on May 28, 2008. The view was obtained at a distance of approx. 185.000 Km (such as about 115000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, angle of 89°.
Image scale is roughly 11 Km (about 7 miles) per pixel".MareKromium

Titan-PIA10503.jpgLooking for Clouds... (IR - natural - but enhanced - colors; credits: Lunexit)90 visiteCaption NASA:"The Cassini Spacecraft peeks through the murk of Titan's thick atmosphere in a search for clouds. Although there are no obvious cloud features in this view, bright cloud streaks have occasionally been seen by Cassini and Earth-based telescopes in the region seen here toward the bottom of Titan's disk. Repeated monitoring observations like this one help scientists build an understanding of Titan's weather and the various climate processes operating on this frigid, but remarkably Earth-like moon.
This view looks toward the Saturn-facing Side of Titan (5150 kilometers, or 3200 miles across). North is up and rotated 35° to the left.
The image was taken with the Cassini Spacecraft narrow-angle camera on Sept. 25, 2008 using a spectral filter sensitive to wavelengths of Infrared Light centered at 938 nanometers. The view was acquired at a distance of approx. 1,7 MKM (such as about 1 MMs) from Titan.

Titan-PIA10546.jpgNorth Polar Haze (Saturated Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)54 visiteCaption NASA:"Titan's globally distributed detached haze layer and the moon's North Polar hood, both notable details of its thick atmosphere, are clearly seen in this image from the Cassini Spacecraft.
Titan is about 5150 Km (approx. 3200 miles) across, and therefore slightly larger than Mercury.
The image was taken with the Cassini Spacecraft narrow-angle camera using a combination of spectral filters sensitive to wavelengths of polarized ultraviolet light centered at 338 nanometers. The view was obtained at a distance of approx. 1,7 MKM (about 1,08 MMs) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 50°.

Titan-PIA11468.jpgFrom the Dark Side... (Natural - but enhanced - Colors; credits: NASA/JPL/Space Science Institute)54 visiteCaption NASA:"From the Dark Side of Titan, the Cassini Spacecraft profiles the moon's Atmosphere as sunlight filters through its upper Hazes.
An airless satellite would appear in this viewing geometry only as a lit crescent. But Titan's thick Atmosphere scatters light around all edges of the Planet to create a ring of light.
Images taken using red, green and blue spectral filters were combined to create this full color view of Titan at high phase. The color in the image on the right has been computer enhanced to bring out the outer haze layer, and the contrast in both images has been enhanced.
This view looks toward the Saturn-facing Side of Titan. North on Titan is up and rotated 45° to the left. The images were acquired at a distance of approx. 1,8 MKM (1,1 MMs) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 157°.
