The image above was beamed back to Earth (as you can see, from not all that far away) some time last week, but I was too busy to post it at the time. This mysterious planet was photographed by our comet-chasing robot friend Rosetta, who was borrowing a tiny bit of momentum from it.

I recommend viewing the high resolution version to appreciate the full beauty of that thin crescent of daylight at the bottom of the image.
