Titan-PIA11622.jpgTitan's Atmospheric Layers54 visiteCaption NASA:"Saturn's moon Titan displays a detached, high-altitude global Haze Layer which is often its most prominent feature in UltraViolet views such as this one.
In this image, Cassini looks down on the North Pole of Titan and, although this view is centered on the Leading Hemisphere of the moon, the Lit Terrain seen here is mostly on the opposite, Trailing Hemisphere of the moon.
The image was taken with the Cassini Spacecraft narrow-angle camera on June 19, 2009 using a spectral filter sensitive to wavelengths of UltraViolet Light centered at 338 nanometers. The view was obtained at a distance of approx. 1,3 MKM (about 808.000 miles) from Titan and at a Phase Angle of 141°.
Image scale is 8 Km (about 5 miles) per pixel".MareKromium

Titan-PIA12320.jpgCrescent Titan (Natural Colors; credits: NASA/JPL/Space Science Institute & Lunexit)103 visiteCaption NASA:"Titan's golden, smog-like atmosphere and complex layered hazes appear to Cassini as a luminous ring around the planet-sized moon. The world beneath that haze has become slightly less mysterious under the gaze of Cassini and its Huygens probe, but many new discoveries await.
This mosaic view of Titan represents "Target 3" in the fall 2009 edition of the Cassini Scientist for a Day contest. (See http://saturn.jpl.nasa.gov/education/scientistforaday8thedition/.) The contest is designed to give students a taste of life as a scientist by challenging them to write an essay describing the value of one target choice among three for Cassini to image.
Images taken using red, blue and green spectral filters were combined to create this color view. Six images -- two sets of three colors -- were combined to create the mosaic. The images were acquired with the Cassini wide-angle camera on Oct. 12, 2009 at a distance of approx. 145.000 Km (such as about 90.000 miles) from Titan".MareKromium

Titan-PIA12817-PCF-LXTT.jpgTitanian "Arrow-shaped Storm" (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)194 visiteCaption NASA:"A huge arrow-shaped Storm blows across the Equatorial Regions of Titan in this image from NASA's Cassini Spacecraft, chronicling the Seasonal Weather Changes on Saturn's largest moon.
This Storm created large effects in the form of dark -- likely wet -- areas on the Surface of Titan, as better visible in later images. After this Storm dissipated, Cassini observed significant changes on Titan's Surface at the Southern Boundary of the Dunefield named Belet.
Those changes covered an area of approx. 500.000 square Km (310.500 square miles), or roughly the combined area of Arizona and Utah in the United States.
The part of the Storm that is visible here measures approx. 1200 Km (745,2 miles) in length East-to-West. The wings of the Storm that trail off to the North/West and South/West from the Easternmost point of the storm are each approx. 1500 Km (931,5 miles) long.
Titan's weather has been changing since the August 2009 Equinox, when the Sun lays directly over the Equators of Saturn and its moons, and Storms at low Latitudes are now more common.
This image is a mosaic of two Cassini images. Most of this view is from an image of the storm captured on Sept. 27, 2010. However, because that image's framing cut off the South Polar Region of the Planet, a second image of Titan, taken on July 9, 2010, was used to fill in that portion of the celestial body. This second image was re-projected to the same Viewing Geometry as the first.
Lit Terrain seen here is in the area between the Trailing Hemisphere, which is the side of Titan that faces backward in its orbit around Saturn, and the side of Titan that always faces away from Saturn. North on Titan is up.
The images were taken with the Cassini Spacecraft narrow-angle camera using a spectral filter of Near-InfraRed Light centered at 938 nanometers. The view was acquired at a distance of approx. 1,3 MKM (807.300 miles) from Titan and at a sun-Titan-Spacecraft, or Phase, Angle of 44°.
Image scale is roghly 8 Km (4,968 miles) per pixel".MareKromium

Titan-PIA12843.jpgWhat's inside Titan?55 visiteCaption NASA:"This artist's illustration shows the likely interior structure of Saturn's moon Titan, as deduced from gravity field data collected by the Cassini Spacecraft. The investigation by Cassini's radio science team suggests that Titan's interior is a cool mix of ice studded with rock, though the outermost 500 Km (approx. 300 miles) appear to be ice essentially devoid of any rock.
Many planets and moons, including the Earth, evolve into a body with a clearly distinct rocky core. This radio science investigation suggests Titan's interior, cool and sluggish, failed to allow the interior to separate into completely differentiated layers of ice and rock.
In addition to the Hazy Surface of Titan (yellow), the layers in the cutaway show an ice layer starting near the Surface (light gray), an internal ocean hypothesized from other Cassini data (blue), another layer of ice (light gray) and the mix of rock and ice in the interior (dark gray). In the background are the Cassini Spacecraft and Saturn, not to scale".MareKromium

Titan-PIA14115.jpgTitan's Haze is going down...80 visiteCaption NASA:"The change in Titan's Haze Layer is illustrated in this figure, derived from data obtained by NASA's Cassini Spacecraft. The picture of Titan in panel "a" was taken on May, 3, 2006, while the picture in panel "b" was taken on April, 2, 2010, several months after Titan's Equinox in August of 2009.
The geometries and Solar Illumination in both images are similar, though Titan's North Pole is at about the one o'clock position (32°) from vertical in panel "a" and nearly vertical in panel "b".
Pictures "c" and "d" magnify the outer regions and show the difference in altitude of the Haze Layer (near 500 Km in "c" and near 380 Km in "d")".MareKromium
