Unusual Giant Cloud on Titan

 According to new studies the mystery of a giant cloud on Saturn’s largest moon Titan may now be solved. NASA’s Cassini spacecraft detected the cloud at Titan’s equator in September 2010. The cloud is huge, with each side running about 930 miles (1,500 kilometers) long. Scientist Jonathan Mitchell at the University of California, Los Angeles, and his colleagues simulated the moon’s atmosphere with a three-dimensional global climate model. The enigma was likely caused by a massive wave rippling through the moon’s atmosphere. According to researchers these extraordinary cloud patterns can result in downpours with up to 20 times the average rainfall.  

These  could  be  key  to  shaping Titan’s surface  by  erosion,  explaining   the widespread presence of certain valleys.This discovery could help scientists better understand similar phenomena on Earth, especially in light of changing global climate.
