I wonder if its a result of some interaction between Titan and Hyperion? <div class="Discussion_UserSignature"> </div>

More likely it's made of proto-solar nebula/cometary/Oort material, which can be heavy in ices & organics. <div class="Discussion_UserSignature"> </div>

I wonder if these Hydrocarbons are related to the dark hemisphere of Iapetus, or is<br />similar to the dark material on Phoebe?<br /><br />Thanks brellis.<br /><br />Very interesting.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

hi Andrew<br /><font color="yellow">I wonder if these Hydrocarbons are related to the dark hemisphere of Iapetus, or is<br />similar to the dark material on Phoebe? </font><br /><br />According to this Lunar and Planetary Science abstract, while Iapetus and Phoebe show clear signs of being related,<br /> <font color="orange">Hyperion<br />is spectrally red at visible wavelengths, similar<br />to D-type asteroids, and has been compared with organic<br />material. We find that at FUV wavelengths, Hyperion<br />is not spectrally redder than the Iapetus dark<br />material, but does appear to have more water ice.<br />Even when we attempt to isolate a spectrum of Hyperion<br />dark material, the Hyperion dark material still<br />appears to have more water ice than the Iapetus dark<br />material – no other spectral variations are apparent.</font><br /><br />From an old Harvard abstract<br /><font color="orange">Structures along the bright-dark boundary, visible in Voyager 2 images, are inconsistent with an eruptive origin for the dark material; this zone is probably the region of grazing impacts of dust spiraling from Phoebe and the dark material is probably a minor component of the ice-dominated surface concentrated in the upper regolith produced by Phoebe-dust bombardment.</font> <br /><br />btw, congrats on reaching "solar system" -- you've joined the <i>illuminati</i>! <img src="/images/icons/cool.gif" /> <div class="Discussion_UserSignature"> <p><font size="2" color="#ff0000"><em><strong>I'm a recovering optimist - things could be better.</strong></em></font> </p> </div>

First, we find much more water in the Solar System than anyone ever expected.<br /><br />Now, we're discovering hydrocarbons in surprising places. There's a picture being painted here, although I'm not sure what it will ultimately be interpreted as.<br /><br />All I see right now is a cosmic Jackson Pollock painting, but it sure is interesting to look at. <div class="Discussion_UserSignature"> <em>"2012..

Thanks brellis.<br /><br />Yes I did think that may be so.<br /><br />The dark Hydrocarbons are absorbing sunlight, causing the crater floors to burn down<br />in the ice, giving Hyperion that peculiar sponge like appearance.<br /><br />Also the overall density of Hyperion is so low, just under that of water ice, meaning that<br />there are probably huge fissures & caverns inside this object.<br /><br />Yes I did suspect that the darker material on Hyperion may be similar to type D asteroids.<br />This only confirms it. Phoebe too has a spectra not too unlike D type asteroids in the darker <br />areas.<br /><br />Hi Dragon04.<br /><br />Yes, I can see that pattern emerging too. First water ice & now Hydrocarbons.<br />The building blocks of life are everywhere we look.<br /><br />Talking of Jackson Pollock paintings, this spectral overlay of a region of Hyperion look just so.<br /><br />Once again, Thank you very much brellis for starting this thread.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

I was just looking back through the Iapetus thread - a lot of great discussion in that thread! <div class="Discussion_UserSignature"> <p><font size="2" color="#ff0000"><em><strong>I'm a recovering optimist - things could be better.</strong></em></font> </p> </div>

I think the Approaching Iapetus thread is one of the best threads on these boards.<br /><br />Not too long now until a rather nice close encounter, with that weird & fascinating<br />moon.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

This link to the CICLOPS, reveals new information regarding Hyperion.<br /><br />Below is a close up of Hyperion from only 2,555 KM.<br /><br />The smallest details are approx 14 metres across.<br /><br />Note the boulders in the top right.<br /><br />NASA / JPL.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
