Cassini captures a high-resolution 60 image mosaic of Saturn's moon Iapetus. The image shows the entire hemisphere of Iapetus (912 miles across) visible from Cassini on its encounter with the two-toned moon in Sept. 2007. The region appears heavily cratered; the most prominent topographic feature being a 280 mile wide impact basin, one of at least nine such large basins on Iapetus. In many places, dark nitrogen-bearing organic compounds called cyanides coat equator-facing slopes and crater floors.

I continue to be amazed by the capabilities of the far-flung NASA cameras, including their ability to radio such images back to Earth. Thanks for showing this.

For God so loved the world that He gave His only begotten Son, that everyone believing into Him should not perish but have eternal life.

Got this one in the VB and didn't know what it was. So I came here to check it out and thanks to your narrative I now know what it is.
Great pic!

It seems to be "un-spheric". Am I right?

Yes you are correct; Iapetus isnít perfectly spherical and is often likened to the appearance of a walnut for want of a better description. This is primarily down to the mountainous ridge that rings the moon and is more apparent on the other image I uploaded from Cassini, Iapetus Approach.

Kind of fascinating to see green organic material on something other than our own planet and at the same time upsetting the golden scientific rules of organics requiring heat & water to exist. The distribution is odd too Ė almost like it has either erupted out of the surface or being scattered from an impact.

as a chemist, i don't know if i would call cyanides "organic". simply having carbon in the structure doesn't make it organic. diamond being one example, carbonates being another. and i am unaware of a rule that states organics need water and heat to occur. i believe simple organic compounds like three carbon aldehydes have been found in gas clouds in space.

A gorgeous image. Must have been one hell of a bang to leave a 450 km crater behind. Such an impact on Earth nowadays would be the end of everything we know.

But it's probably a very old crater, back from when our primary planets and moons were still accreting matter.

To err is human, but if the eraser wears out before the pencil, you're overdoing it a little.
