From the explanation

“Seen to the left of Saturn’s banded planetary disk, small icy moons Dione and Rhea are caught passing in front of the gas giant’s extensive ring system in this sharp telescopic snapshot. The remarkable image was recorded on November 20 , when Saturn’s rings were nearly edge-on when viewed from planet Earth.”
