dholmes, Very good comment! I've been fascinated with the point of view thing for some time, Macro, Micro, Albedo, Wavelengths, Resolution. It's amazing what information can be found in seemingly small packages.
Thanks for the pictures! Are there any color pictures available?

That may be true mhovland as in your example of serpentinization, but if you study the history of science and discovery in general you will notice that there are many pieces to the puzzle of "what's out there". Forgive this simple analogy but allow me to mention the following. Say for instance you are at the beach and you are standing on the shore looking out. You see nothing but a flat blue lifeless horizon of ocean. No signs of life anywhere. A friend comes along and invites you to go with him on a plane ride up the coast. Now you are flying over the same beach looking down, and you notice something. Less than 50 yards from where you were standing is a school of mullet being chased by 5 or 6 large Tiger sharks that moments before you never knew were there. That is basically one of the principles of discovery. Its all a matter of changing one's point of view.

So sorry for dissappointing you believers in organisms for the development of the observed gas jets from Enceladus. However, there are many different processes also operating on Earth that produce abundant CO2, H2, or Methane, CH4. These are inorganic substances that are produced by the earth and other underground processes involving water and rock at elevated temperatures. One of the most important such process is serpentinization, that produzes abundant amounts of these common elements.

Dear team,

Congratulations!

Very, very well done!
