Saturn’s Moon Enceladus Transiting in Front of Rhea

Saturn’s moon Enceladus transiting in front of its larger moon Rhea, as seen from a couple million miles away by the Cassini spacecraft, in photographs that span about one minute’s worth of time. That we can know to point cameras at this kind of event and get images this nice is a bit of a wonder to me.
