What appears as a pair of bright dashes at the center of this image is one of the features rings scientists have dubbed "propellers."
This particular propeller, named Bleriot, marks the presence of a body that is much larger than the particles that surround it, yet
too small to clear out a complete gap in the rings (like Pan and Daphnis) and become a moon in its own right. Although the moonlet
at the core of the propeller is itself too small to see, the disturbances in the rings caused by its gravity betray its presence.
This view looks toward the sunlit side of the rings from about 59 degrees above the ring plane. The image was taken in visible light
with the Cassini spacecraft narrow-angle camera on Jan. 9, 2017. The view was acquired at a distance of approximately 359 000
kilometers from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 73 degrees. Image scale is 2 kilometers per pixel
