The view from Saturn

This amazing image was taken by NASA's Cassini space probe, and has been labelled with each of the notable features in view. Not only can we see Saturn and a host of its moons (Enceladus, Epimetheus, Prometheus,Tethys, Janus, Mimas and Pandora), we can also see three of the inner planets: Mars, Venus and our own Earth, under the ring on the lower right.

If you can't make this image out well, I pinched it from io9 which goes into more detail about the process of the image capture, and has a higher-res copy. For the very best experience, though, visit CICLOPS, the Cassini Imaging Central Laboratory, and open up the full-res file. Astonishing.
