Earth, from Saturn

Gotta love earth from space, on any scale. My favorite recent image is taken by Cassini in orbit around Saturn. In this image, Saturn has eclipsed the Sun. And in this view there's a four-pixel sized speck to the left of the ball, outside the ring, barely visible without a zoom. That's Earth.
