It seems strangely appropriate that my next post after White Christmas should also involve frozen water. I first saw this photo on El Pais and thought: how cool! Then I did a little research to figure out the story behind the picture (because my Spanish, as we all know, sucks: all I got from El Pais was "a moon of Saturn exhales columns of water vapor"). I find here that Enceladus, one of Saturn's moons that I didn't even know existed, is supplying ice to the A-ring around the giant planet. Scientists had been observing water in the ring since the 1990s but didn't know the source of it. Now they do.It seems that things in space operate pretty much the same as here on earth: finding the puddle is easy—finding the leak ain't.
