Cassini spacecraft natural colour image of a portion of the inner-central part of Saturn's B ring. The narrow ringlets at centre measure around 40 kilometres wide, the bands at right measure 300 to 500 kilometres wide. The rings, which consist of particles of nearly pure water ice, have become contaminated with meteoritic dust over time. It is this dust that causes differences in the rings' colours. Image obtained by the spacecraft's narrow-angle camera on the 6th July 2017, at a distance of approximately 76,000 kilometres from the area pictured.
