Titanian Northern Lakes (6)

Caption NASA originale:"This Cassini radar image shows two lakes "kissing" each other on the surface of Saturn's moon Titan.
The image has been taken from a fly-by occurred on Sept. 23, 2006, and covers an area of about 60 Km (approx. 37 miles) wide by 40 Km (approx. 25 miles) high.
This pass was primarily dedicated to the ion and neutral mass spectrometer instrument, so although, the volume of radar data was small, scientists were amazed to see Earth-like lakes. With Titan's colder temperatures and hydrocarbon-rich atmosphere, however, the lakes likely contain a combination of methane and ethane, not water.
In this image, near 73° North Latitude and 46° West Longitude, two lakes are seen, each 20 to 25 Km (approx. 12 to 16 miles) across. They are joined by a relatively narrow channel. The lake on the right has lighter patches within it, indicating that it may be slowly drying out as the Northern Summer approaches".
