Possible Cryovolcano Discovered on Titan 116
Rei writes "NASA's Jet Propulsion Laboratory is reporting that the Cassini spacecraft has observed what appears to be a cryovolcano on Saturn's moon Titan. Given the absense of a global methane sea on Titan, the snail-shaped structure with what appears to be a caldera on top could explain how Titan's methane stays replenished. It could further explain the dry drainage channels discovered by the Huygens lander as being formed by heavy methane rainfall after eruptions."

I don't know why this hasn't received more coverage: Iapetus [enterprisemission.com]
Maybe you've all seen this already, so I don't know if anyone cares. Basically, Iapetus is not spherical! It is an enormous Buckmister-Fuller skeletal structure! It has also been observed from earth (with radio telescopes) to have a dull, uniform radar signature despite its obvious surface features - but consistent with its unusual, non-spherical geometry. ie: it's stealthy!
There is a 60 000 foot high 'wall' around its equator - perfectly around its equator. This is an impossibly coincidental geological feature. But again, it is empirically consistent with a gradual surface erosion which will reveal an underlying bucky-fuller skeleton.
What could very possibly be an alien artefact has been hushed up. NASA continually draws more attention to Titan, but it's the outermost Iapetus that is far more intriguing. If it wasn't so, how come NASA has scheduled an originally unplanned second flyby?! No, I am not wearing a tin-foil hat!
Don't be fooled by the "Titan smokescreen" (my term for it). Iapetus ('eye-app-e-tis') is the truly significant Cassini investigation.

Titan's atmosphere is much, much thicker than the atmosphere on Triton, Ganymede, or Enceladus. These other moons have atmospheres but they are much thinner than even Mars' atmosphere. Hence the 'substantial' qualifier about Titan's atmosphere (which is thicker than Earth's).
