Titanian Northern Lakes (5)
|
Caption NASA originale:"This lake is part of a larger image taken by the Cassini radar instrument during a flyby of Saturn's moon Titan on Sept. 23, 2006.
It shows clear shorelines that are reminiscent of terrestrial lakes. With Titan's colder temperatures and hydrocarbon-rich atmosphere, however, the lake likely contain a combination of methane and ethane, not water.
Centered near 74° North Latitude and 65° West Longitude, this lake is roughly 20 by 25 Km (about 12 to 16 miles) across. It features several narrow or angular bays, including a broad peninsula that on Earth would be evidence that the surrounding terrain is higher and confines the liquid. Broader bays, such as the one seen at right, might result when the terrain is gentler, as for example on a beach".
