The NASA Cassini spacecraft has been looking at Saturn's moon Titan a little more closely of late, especially at the lakes and seas that occur on mainly just one small area of the Moon (or the visible face of Titan). These appear to be located in the north – see www.jpl.nasa.gov/news/news.php?release=2013-304&utm
The same story is at http://phys.org/print306088467.html … and we learn that the lakes are liquid methane and ethane, distinctly diffrerent, from the situation on Earth – or is it? Methane seeps are known to exist and lots of it is supposed to be locked up in the permafrost zone. It also gets into the atmosphere – and everyone one knows all those nasty ruminants belch methane from eating too much grass. Its all part of the vegan dream of our future – a world without abbatoirs. Well, it seems they have lakes of the stuff on Titan – and not a cow in sight.
