Earth and Moon, from a distance

NASA's MESSENGER mission took this image of the Earth and Moon as seen from 114 million miles away. That's more that the distance between the Earth and the Sun. Notice that they're lit up nicely since they (we!) are being viewed from the inner solar system.The image credit is NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington.

That reminds me of another nice NASA photo, this one from Cassini. In this one, the Earth and Moon are visible through Saturn's rings. This is the view from the outer solar system. The upper left has a blow-up of our home since it's just a small blip in the full image.
