A massive mountain range lying just south of TitanтАЩs equator runs northwest-southeast through this newly released image from the Cassini spacecraft. The range, called by scientists тАЬTitanтАЩs Sierra,тАЭ extends 93 miles (150 km) long by 19 mi (30 km) wide. Cryogenic lava, a soup of ammonia and water, welling up from below as TitanтАЩs crust was pulled apart tectonically probably created it. The image was created on October 25, 2006, during a flyby that returned CasssiniтАЩs highest-yet resolution views of the saturnian moon. The picture reveals features as small as 1,300 feet (400 meters) across.
