NASA’s James Webb Space Telescope captured the central region of the Bullet Cluster with its NIRCam (Near-Infrared Camera). The scene contains two massive galaxy clusters that sit on either side of the large, light blue spiral galaxy at the center. Webb’s extremely precise images revealed many more distant galaxies and faint objects, allowing a research team to refine the amount of mass in the two galaxy clusters.
