Cassini 'Tastes' Organic Material at Enceladus 70

Posted by Zonk from the why-does-saturn's-icy-moon-taste-like-ecto-cooler-hi-c dept.
Riding with Robots writes "As previously reported, the robotic spacecraft Cassini recently flew through the mysterious geyser plumes at Saturn's icy moon Enceladus. Today, NASA released the preliminary results of the flyby, including some intriguing findings, such as organic materials 20 times denser than expected and relatively high temperatures along the fissures where the geysers emanate. 'These spectacular new data will really help us understand what powers the geysers. The surprisingly high temperatures make it more likely that there's liquid water not far below the surface,' said one mission scientist."

      "Compounds containing carbon".

      That's all it means, really. Methane is a common one.

        or to be more precise by citing wikipedia:

        Organic chemistry is a specific discipline within chemistry which involves the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of chemical compounds consisting primarily of carbon and hydrogen, which may contain any number of other elements, including nitrogen, oxygen, the halogens as well as phosphorus, silicon and sulfur.

          it should be noted however that otherwise "organic" compounds containing boron or silicon are often not characterized as being organic, usually they are referred to as being part of organometallic chemistry. th is even though boron and silicon are not strictly metallic, they are in fact semiconductors.

        Is CO2 organic?

          Nope. You need both carbon and hydrogen, and CO2 has no H. I believe the simplest organic molecule is methane, CH4. It's also hydrocarbon, which means it contains only carbon and hydrogen. Alternatively formaldehyde, CH2O, could be considered simplest, depending on how you define "simple". Then you get more complex stuff by adding more carbon (and hydrogen as much as that new carbon needs), and by adding other elements, like replacing an H in a hydrocarbon with an OH gives alcohols, most importantly from C2

            Just to be picky, you don't actually need hydrogen. I reckon most chemists would count hexafluorobenzene as organic. Even with just carbon and oxygen, benzene-1,2,3,4,5,6-hexacarboxylic acid trianhydride (C12O9) would be classed as organic.

            A better definition might be, "Contains carbon, does not contain metals (inc. semimetals)", with carbon dioxide and carbonate excluded for historical reasons" :).

      traditionally organic meant that it was produced by life and not synthetic- then we figured out how to synthesize a lot of these chemicals and now it pretty much means contains carbon and usually hydrogen. carbon dioxide for example contains carbon but isn't considered organic and neither is pure carbon. water is a vital component of life as we know it and is almost always associated with organic compounds at least in vivo although it too is not considered organic because it doesn't contain carbon, it does however contain hydrogen and oxygen which are very common in organic compounds.
    • Organic molecules are typically defined as any carbon compound that is not CO2.
      Things such as methane (CH4) are organic molecules.

      Yeah thats an old joke. There is so much methane in the solar system that the real question is where would you find enough oxygen to be able to burn it?

      Its right there, free for the taking, but too expensive to extract and transport.

    ...is that Enceladus has a chemical makeup far and away closer to a comet than to a Saturnian body, but cannot be a captured comet. The speculation I've read suggests it may have been bombarded by so many comets that the overall chemistry may have changed, but we've a name for objects like that -- dust. Being smashed into by objects that must have been many times the mass of the original moon, for there to have been a significant effect, would have reduced the proto-Enceladus into puree-of-moon.

    I'm wondering if that, in fact, happened - that there was one almighty pulverization and the modern Enceladus is the result of the lighter material condensing around a surviving fragment of sufficient size to act as a nucleus. In that case, though, there should be another moon formed from the heavier material condensing around another fragment, showing an abnormally high density, in much the same way that the Earth and its moon unevenly divide the material of the original planet.

    So far, I've not seen anything that suggests that is the case, but since so little is actually known, I guess it's well within the realms of possible at this point.
