The ghostly features in Saturn's B ring called spokes are making an appearance again as the Cassini spacecraft continues its tour of the Saturn system. These dusty features on the rings are often wedge-shaped, as this one is, with the inner portions of the spoke being wider than the outer portions due to electromagnetic effects on the dust particles.
