Lake Asymmetry on Titan
NASA/JPL/Caltech/University of Arizona/Cassini Imaging Team · Download full size image
This image shows the northern and southern hemispheres of Titan, showing the disparity between the abundance of lakes in the north and their paucity in the South. The hypothesis presented favors long-term flux of volatile hydrocarbons, predominantly methane, from hemisphere to hemisphere. Recently the direction of transport has been from south to north, but the effect would have reversed tens of thousands of years ago. Posted on: 30 Nov, 2009
