Is this an Ocean? Titan Image
I seriously think this is the first compelling image of an ocean outside of Earth. It may not be Water....but liquid none the less. Guess we will know pretty soon and I for one am excited.
Look for the Dark areas....and tell me what it looks like to you. http://www.rednova.com/news/display/?id=97548 Cassini Eyes Titan's Xanadu Image credit: NASA/JPL Jet Propulsion Lab -- This image taken on Oct. 24, 2004, reveals Titan's bright "continent-sized" terrain known as Xanadu. It was acquired with the narrow angle camera on Cassini's imaging science subsystem through a spectral filter centered at 938 nanometers, a wavelength region at which Titan's surface can be most easily detected. The surface is seen at a higher contrast than in previously released imaging science subsystem images due to a lower phase angle (Sun-Titan-Cassini angle), which minimizes scattering by the haze. The image shows details about 10 times smaller than those seen from Earth. Surface materials with different brightness properties (or albedos) rather than topographic shading are highlighted.

It will be further processed to reduce atmospheric blurring and to optimize mapping of surface features. The origin and geography of Xanadu remain mysteries at this range. Bright features near the south pole (bottom) are clouds. On Oct. 26, Cassini will acquire images of features in the central-left portion of this image from a position about 100 times closer. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

The Cassini mission has done so well, I can't wait to see what else it finds. Who knows what that dark patch could be. If it is an ocean of somekind, that would open up so many possibilities. Very exciting indeed.

I certainly hope it is water, cause that would greatly reduce the support for the idea that earth is the only place capable of supporting life.

That would be unusual for there to be such a visible contrast in albedo without both solid ground and liquid. I know they enhanced the contrast, but that is usually a pretty good indicator that it is liquid. However, I highly doubt that it's water. On the other hand, it might just be that the surface material is more densely packed in the whiter areas. I know that in most active remote sensing they use a fairly high energy beam that often penetrates lower density surface features a bit before getting reflected back. That might make it appear to be a different material.
I'd be interested to see remote images of it in the visible wavelengths to take better guesses at this, but then I guess that kind of thing is unnecessary with the probe and all

i thought they were just a deep impression on the surface like a chasm or something.

Current speculation seems to point to a possible liquid methane....or ammonia ocean/lake, on the surface. If indeed there is a liquid, it would serve as a mixing bowl for chemical reactions regardless of the composition, although not as suitable as water. Still, even the chance of the expected organic rain from the atmosphere interacting to create some form of life is wonderful to consider.

i think pluto, or a moon of it, has water. it was previouslsy thought to be all ice, but the friction of huuuuge blocks of ice creates enough energy to melt some of it. im not too sure on this though |

I think that you would be suprised how little you need to support life, K-Wise. Life on earth started with virtually nil in the way of subsistance. The conditions on our planet when life began were supposedly much much worse than anything that we find in the solar system, perhaps more akin to Venus or Mercury than someplace relatively welcoming like Titan...
Unless you beleive that we all got made in seven days. In that case, no, Titan would not be a suitable place to support life if it had only water. |

If the conditions the earth were in when life began were still the same, and not that of what we have today, we and everything else on earth would probably die. All kinds of elements had to come together before life could inhabit the earth.

I suppose it's pretty possible. Hard to know though. Not a genius

This is really excellent.
I love unknown puzzles like this and our solar system, never mind further afield, is full of them. It is great that we will know fairly soon if this is a liquid or not. Even a methane/ethane ocean has to help prove what is possible in our own little back yard. If we can have oceans of different mixes in this little piece o space, what can be possible in the vast universes? Of course, we will probably never know, but it doesn't stop the imagination running wild! |

Didn't they already say that it had oceans of liquid methane?

The BBC has some info on titan for those of us who don't know much about it (read: me)
That said those images are really cool. Kinda reminds me of Aurthur Clarke's Space oddessey's and Eurpoa...except wrong planet wrong moon, but hey it's close!
