The Year in Pictures 2009


Another World
The planet Saturn is captured in a photograph taken by the Cassini orbiter. Carolyn Porco, the leader of the Imaging Team on the Cassini mission to Saturn, comments, "This year we had the thrill of observing the Saturn equinox. That's the moment when the sun, seen from Saturn, crosses the equator going from south to north. The sun sets on the rings, illuminating them edge-on. The geometry revealed structures and phenomena in the rings we had never seen before. We saw this famous adornment spring from two dimensions into three, with some ring structures soaring as high as the Rocky Mountains. It made me feel blessed."
