Webb near-infrared data combined with Chandra X-ray data of the Bullet Cluster show many overlapping objects, including foreground stars, galaxies in galaxy clusters, and distorted background galaxies behind the galaxy clusters. The objects are all at various distances set against the black background of space. Most galaxies appear as tiny fuzzy ovals in white, orange, or red. A slightly larger, very bright, light blue spiral galaxy is at center. To its immediate left and right are two large bright pink splotches representing X-rays. The right pink area has a rounded nose facing right, where it is darker pink, and fades to the left as a triangular shape. This is referred to as the Bullet. To the far left and far right, next to the pink regions, are two blue regions representing dark matter mass. The left blue region is a large, long oval at an angle. The blue region at right is a far smaller oval.
