This isn't a a lens problem you're seeing as NASA's Cassini spacecraft snaps images of Saturn's moons, Tethys and Titan. It's actually one of Saturn's rings impeding the clear shot, an occurrence that NASA writes is a "welcome disruption".
NASA describes the image as from Saturn's perspective facing Tethys in the background and to the left and Titan in the center. The spacecraft took the image in invisible red light on Dec. 7, 2011, with Tethys 1.4 million miles away and Titan at 1.9 million miles.
The photo was taken as part of the Cassini Solstice Mission, which is underway until 2017 in collaboration with the European Space Agency and the Italian Space Agency.
Here are some other photos from the mission:
