Star trails streak across the rings of Uranus in this dramatic image captured by Voyager 2. The combination of unique geometry (it was taken from the highest phase angle at which Voyager imaged the rings) and a 96-second-long exposure reveals lanes of fine dust particles not visible from other viewing angles. These images and others captured by Voyager 2 in 1986 allowed scientists to identify 11 known rings around Uranus.
