Lakes of methane and ethane on Saturnís moon Titan

Lakes of methane and ethane on Saturnís moon Titan

Fig. 10.26 . A radar image shows a bright, central island in a dark, smooth lake, surrounded by a bright shoreline with numerous inlets. The island is about 90 kilometers across. This is one of many large lakes formed at high latitudes on Titan, with more in the northern polar regions than the southern ones. Seasonal rains of liquid methane and ethane probably fill these lakes. The radar instrument aboard Cassini obtained this image during a close south polar flyby on 22 February 2007.
