Springtime on Saturn

4987_11355_1[Cross posted from the Kentucky Space blog] Having toured the Saturn system for four years now, the intrepid craft Cassini has snapped 150,000 images, discovered organics venting from Enceladus and dispatched Huygens to the surface of Titan, which, as we now know, is an organic chemistry factory with a complex hydrology that suggests something about the possibility of life.

That length of time has also enabled scientists to observe a very slow change in the northern pole. The blues and grays are are gradually diminishing in intensity as "winter gives way to spring."
