The image's organization is similar to that of a cat's eye. A bright almost pinpoint white circle in the center depicts the central star. The central star is encapsulated by a purple and red irregularly edged, elliptically shaped area that suggests a three dimensional shell. This is surrounded by a pair of superimposed circular regions of red with yellow and green edges, suggesting another three dimensional shell.
