Punga Mare (240 miles, or 390 kilometers, across) is seen simply inward a higher house the oculus of the mosaic, amongst Ligeia Mare (300 miles, or 500 kilometers, wide) below oculus in addition to the vast Kraken Mare stretching off 730 miles (1,200 kilometers) to the left of the mosaic. Titan's numerous smaller lakes tin move seen about the seas in addition to scattered about the correct side of the mosaic. Among the ongoing mysteries most Titan is how these lakes are formed.
Another mystery at Titan has been the weather. With its dense atmosphere, Titan has a marsh gas wheel much similar Earth's H2O wheel of evaporation, cloud formation, rainfall, surface runoff into rivers, in addition to collection inward lakes in addition to seas. During Titan's southern summer, Cassini observed cloud action over the southward pole.
However, typical of observations taken during northern jump in addition to summer, the persuasion hither reveals solely a few pocket-sized clouds. They appear equally vivid features simply below the oculus of the mosaic, including a few inward a higher house Ligeia Mare.
"We expected to a greater extent than symmetry betwixt the southern in addition to northern summer," said Elizabeth ("Zibi") Turtle of the Johns Hopkins Applied Physics Lab in addition to the Cassini Imaging Science Subsystem (ISS) squad that captured the image. "In fact, atmospheric models predicted summertime clouds over the northern latitudes several years ago. So, the fact that they yet hadn't appeared earlier the cease of the mission is telling us something interesting most Titan's marsh gas wheel in addition to weather."
"Titan is a fascinating house that actually teases us amongst some of its mysteries," said Turtle.
The images inward this mosaic were taken amongst the ISS narrow-angle camera, using a spectral filter sensitive to wavelengths of near-infrared low-cal centered at 938 nanometers.
The persuasion was obtained at a distance of around 87,000 miles (140,000 kilometers) from Titan. Image scale is most 0.5 miles (800 meters) per pixel. The icon is an orthographic projection centered on 67.19 degrees N latitude, 212.67 degrees due west longitude. An orthographic persuasion is most similar the persuasion seen past times a distant observer looking through a telescope.
