A two-panel image of a supernova remnant. At left, a mottled light pinkish-orange oval whose inner edge resembles a string of pearls. Within the oval is a dense blue-green cloud, shaped like a keyhole. Three stars with six-point diffraction patterns surround the oval. Above and below these structures, are very faint orange rings, which form a figure eight pattern. The inner portion of the supernova remnant is surrounded by a white box whose edges correspond to the border of the second image. At right, a bright orange ring with an orange dot in the middle.
