|A diagram of Saturn's rings illustrating the paths taken by the star Omicron Ceti during four recent occulatations observed by the Cassini spacecraft. Bars at each path show the amount of light that filtered through the rings at points along the occultation. Inset boxes illustrate the orientation of gravitational wakes relative to the direction from the spacecraft to the star at select points in the A ring.
