Debris disks around stars naturally form complex structures without the presence of a planet. This image shows the dust density and the growth of structure in a simulated disk, which extends about 100 times farther from its star than Earth's orbit around the sun. At left, the disk is seen from a 24-degree angle; at right, it's face-on. Lighter colors show greater dust concentrations.
