A three-panel image of a supernova remnant. The left panel is labeled “NIRCam” while the two right panels are labeled “MIRI M R S Argon two” (at top) and “NIRSpec I F U Argon six” (at bottom). 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 center of the supernova remnant is surrounded by a white box with lines leading to the upper and lower right of the image, where two stacked panels show a bright orange ring with an orange dot in the middle. The upper panel is fuzzier and more blobby, while the bottom panel has more clearly defined edges around the ring and central dot.

A trail of dark, dim dust stretches from below the galaxy up and off to the left, where there are three more bright patches. The background around the galaxy is quite dark. It holds a few small background galaxies and one bright, foreground star.
