NASA's Cassini Discovers Hydrocarbon Dunes On Titan (examiner.com)

Posted by samzenpus on from the different-dunes dept.

MarkWhittington writes: NASA made an announcement that Titan, a moon of Saturn and the largest moon in the solar system, has hydrocarbon dunes. The discovery has highlighted the entirely alien nature of Titan, which has seas, lakes and rains of liquid methane and ethane and a surface comprised on water ice. The fact that it has dunes made of frozen hydrocarbon that acts like sand, blown by the wind on Earth is yet another piece of data that has scientists interested in studying Titan further.

  1. FYI: Titan is second largest in Solar System by Anonymous Coward · · Score: 4, Informative

    > the largest moon in the solar system

    Jupiter's Ganymede has a diameter of 5268 km and Titan has a diameter of 5151 km. Titan is the second largest moon in the Solar System.

      Which is interesting that they are bigger than mercury. So mercury is planet only because of orbiting the sun, while these moons are not.

    So we have to extend the Keystone XL pipeline all the way to Titan, now.

    For the shear amount of hydrocarbons that we find on other planets, moons, etc, it makes me wonder about our oil. I would not be surprised to find out that some of this oil comes from before life.

  4. Oxidizer by coolmoose25 · · Score: 5, Interesting

    On Earth, we refer to hydrocarbons as fuel, and we use the oxygen in our atmosphere to burn them. We call the air an "Oxidizer"

    On Titan, if there were any "natives", would they call oxygen "fuel" and their hydrocarbons "Hydrocarbonizers"?

    They have hydrocarbons? Looks like they need some Freedom!

    The number of posters who seem to think that fossil fuels are the only type of hydrocarbon makes me sad. Sure, some of them are making jokes, but there are more than a handful who appear to be actually serious in this belief.

    Believing that dinosaurs had to exist before hydrocarbons requires the most bizarre self-contradictory theory of Creationism ever conceived.

    There are lots of hydrocarbons which aren't fuels at all, fossil or otherwise. (Or at least would make poorer fuels than non-hydrocarbons.)
