In her remarks on Saturday, Professor Jani Radebaugh indicated that earth can be seen, barely, in the background of the picture of Saturn that I appended to this blog entry on Saturday night.
The photo was taken from a satellite that had passed beyond Saturn and that was, accordingly, aiming its camera back toward the center of the solar system.
Earth was very, very far away. Can you find it? Feel free to enlarge the photo. In fact, you may need to do so.
(Hint: There are, I think, two possibilities. I believe I know which one is the right one, and will be happy to reveal the answer at some not-too-distant time.)
