Titan-Seas-Kraken_Mare-PIA11626-01.jpgKraken Mare (the Map)58 visiteKraken Mare is - so far - the largest known body of liquid on the Surface of Titan.
It was discovered in 2007 by the Cassini Probe and was so named in 2008 after the Kraken, a legendary sea monster. Kraken Mare is believed to be the largest of numerous seas and lakes in Titan's North Polar Region.
It should be a sea of Hydrocarbons whose discovery was further confirmed by Radar Imagery. Only a portion of the Kraken Sea has been imaged by radar, but its wider extent is indicated in Visible Light images that indicate a larger expanse. Kraken Mare is believed to be similar in size to the Caspian Sea. An island in the sea is named Mayda Insula.
As part of the proposed "Titan/Saturn System Mission", a probe would splash down on Kraken Mare in order to study and scrutinize its composition, depth and numerous other properties.
Nota Lunexit: "...and numerous other properties...". Quali??? Lifeforms living into it, maybe???...MareKromiumNov 19, 2009

Titan-Seas-Kraken_Mare-PIA11626-00.jpgKraken Mare (Natural Colors; credits: Lunexit)58 visiteCaption NASA:"In the top right of this Cassini image, the Southern end of Titan's huge lake of liquid hydrocarbons called Kraken Mare is visible near the moon's North Pole.
See PIA11146 to learn more about Titan's lake districts and to see a map.
Near the moon's Equator are the albedo features Senkyo on the right and Aztlan on the left. This view looks toward the Saturn-Facing Side of Titan. North is up and rotated 31° to the right.
The image was taken with the Cassini Spacecraft wide-angle camera on Oct. 12, 2009 using a spectral filter sensitive to wavelengths of Near-InfraRed Light centered at 939 nanometers.
The view was acquired at a distance of approx. 252.000 Km (about 157.000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 11°.
Image scale is roughly 15 Km (a little more than 9 miles) per pixel".MareKromiumNov 19, 2009

Titan-PIA11622.jpgTitan's Atmospheric Layers55 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".MareKromiumNov 12, 2009

Titan-PIA11610.jpgEclipsed Titan (Natural Colors; credits: Lunexit)66 visiteCaption NASA:"Titan becomes obscured as it moves into eclipse by Saturn. Using a camera filter sensitive to Near-InfraRed light, this image manages to show albedo features on the moon. For a view of Titan in eclipse taken in visible light, see PIA11508.
As it moves into Saturn's shadow, Titan is lit by two sources. Most of the light comes from refracted Sunlight passing through the edge of Saturn's Atmosphere, but Sunlight reflected off the Planet's Rings also reaches the moon.
This view looks toward the Trailing Hemisphere of Titan. North on Titan is up and rotated 28° to the left.
The image was taken with the Cassini Spacecraft narrow-angle camera on Sept. 11, 2009 using a spectral filter sensitive to wavelengths of Near-InfraRed light centered at 938 nanometers. The view was acquired at a distance of approx. 2,5 MKM (such as about 1,6 MMs) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 85°.
Image scale is roughly 15 Km (a little more than 9 miles) per pixel".MareKromiumOtt 30, 2009

Titan-PIA12320.jpgCrescent Titan (Natural Colors; credits: NASA/JPL/Space Science Institute & Lunexit)105 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".MareKromiumOtt 23, 2009

Titan-PIA11603.jpgSeasonal Changes on Titan (Natural Colors; credits: NASA/JPL/Space Science Institute)55 visiteSeasonal changes in the Atmosphere of Saturn's largest moon are captured in this Natural Color image, which shows Titan with a slightly darker top half and a slightly lighter bottom half.
Titan's Atmosphere has a seasonal hemispheric dichotomy, and this image was taken shortly after Saturn's August 2009 Equinox.
Images taken using red, green and blue spectral filters were combined to create this Natural Color view.
Scientists have found that the Winter Hemisphere typically appears to have more high-altitude haze, making it darker at shorter wavelengths (UltraViolet through blue) and brighter at InfraRed wavelengths.
The switch between dark and bright occurred over the course of a year or two around the last Equinox. Scientists are studying the mechanism responsible for this change, and will monitor the dark-light difference as it flip-flops now that the 2009 Equinox has signaled the coming of Spring and then Summer in the Northern Hemisphere.
Although this hemispheric boundary appears to run directly East-West near the Equator, its position is not level with latitude and is actually offset from the Equator by about 10° of Latitude.
This view looks toward the Saturn-facing side of Titan. North on Titan is up.
The images were obtained with the Cassini Spacecraft wide-angle camera on Aug. 25, 2009 at a distance of approx. 174.000 Km (such as about 108.000 miles) from Titan.
Image scale is roughly 10 Km (a little more than 6 miles) per pixel.MareKromiumOtt 18, 2009

Titan-PIA11567.jpgTitan's Atmosphere... (Natural Colors; credits: Lunar Explorer Italia)73 visiteCaption NASA:"The Cassini Spacecraft looks at Saturn's largest moon, Titan, revealing its halo-like ring formed in the upper hazes of the moon's extensive Atmosphere.
This view looks toward the darkened Leading Hemisphere of Titan, but lit terrain seen here is on on the Trailing Hemisphere and anti-Saturn side of the moon.
The moon's North Pole lies on the Terminator between the illuminated and unilluminated parts of the moon. The Pole is rotated 11° to the right in this image.
