This picture between Saturn's rings was taken on April 12. Saturn's disk blocked the Sun so Cassini was looking
toward the inner Solar System and the gas giant's backlit rings. At the top of the mosaicked view is the A ring with its broader Encke and narrower Keeler gaps visible. At the bottom is the F ring, bright due to the viewing geometry. The point of light between the rings is Earth, 1.4 billion kilometers in the distance. Look carefully and you can even spot Earth's large moon, a pinprick of light to the planet's left.
I clicked to enlarge the image and was just able to see our Moon. (Or maybe I need to clean my laptop screen.)
