This image was brought up in Carolyn Porco's lecture at TED.
She commented, …"You can see it here, next to England, just to show you the size. This is not meant to be a threat. (audience laughter). "
This occurs toward the end, in Carolyn's lecture, at counter 13:08.
At 16:33, she shows the famous image of Saturn, taken from the 'back', with the sun- eclipsed by the planet. We can't see her little laser pointer in the video, but she says that this image includes the distant Earth, which is, …"cradled… in Saturn's rings".
i've looked at a larger photo of this image:
There is a little dot in the rings on the left side. Maybe that is us.
