And in a completely different scale…

In Huygens Sends Images of Titan, from National Geographic News, one can read: Titan is sitting up there perking away as kind of a planet-scale chemistry lab doing a lot of the stuff that was going on in the Earth’s atmosphere four billion years ago. In the previous post we have a “lab-on-a-chip”, here we have a “planet-scale-chemistry-lab”. It is really a matter of scale… Ah, the article is excellent and is a valuable reading.
