A fantastic collection of new images of the northern lakes has just arrived: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=298704

Fascinating that ethane is being framed as a salt analogue in the seas. The chemistry of Titan is astonishingly alien.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

QUOTE Fascinating that ethane is being framed as a salt analogue in the seas. The chemistry of Titan is astonishingly alien. I wondered about that as well. I suspect they're using that term to mean it creates a denser fluid like saltwater in contrast to lower density freshwater. The changes in visibility could akin to the vertical salt line in rivers and estuaries where freshwater meets sea water but doesn't mix much because of density differentials. This makes sense, ethane mixed with methane will be significantly denser to pure methane. If the flow is slow enough, lakes look something like a 1960s layered-cocktail e.g. Tequila Sunrise, with methane-ethane on the bottom and methane on the surface. https://www.adn.com/science/article/mythbus...a/2013/02/05/#_ |
