Well, even U.S. scientists are very careful about the potential for organic contamination. Hopefully the satellite isn't simply detecting something deposited onto the detectors or nearby areas on the spacecraft. Carbon and oxygen are all over the universe, so even if contamination isn't a problem, detection of organics on the moon is not a surprise. To give an idea about the abundance of carbon, very large stars may end up in a carbon-nitrogen-oxygen (CNO) burning phase once they're used up all their heavier elements. What is really of interest is what organic molecules have been found. Amines would be exciting; particularly if they are amino acids.

I'm no geologist (yet) and I have only looked superficially at this but the feature reminds me of what can be seen with columnar jointing. Nature can be amazingly precise and geometric sometimes. Normally it's basalt, and the ocean is pretty much basalt at the top-most levels of the ophiolite. If the basalt cools from the exterior, this can happen. I don't know if this can occur in the ocean as we tend to get pillow lavas as the basalt cools INCREDIBLY FAST and kinda oozes out. Also, with the extent of this feature, this would have to have been some sort of flood of basalt.

It's a pretty neat feature, real or unreal. Although I have to wonder what these people think about the very long linear feature called the Ninetyeast Ridge in the Indian ocean. Anyhow, got to love the masters of pattern: humans. Never fail to see things where there's really nothing.
