Bullet Cluster Hubble to Webb Fade

Video fades between images of the Bullet Cluster taken by NASA’s Hubble Space Telescope and NASA’s James Webb Space Telescope. More distant galaxies pop into view with Webb’s near-infrared observation.

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, set against the black background of space. A large blue oval, two pink areas, and a smaller blue area are layered on top.

Bullet Cluster (Webb and Chandra Image)

The Bullet Cluster is made up of two massive galaxy clusters. Webb shows a vast number of galaxies and foreground stars in near-infrared light. Glowing, hot X-rays captured by NASA’s Chandra X-ray Observatory appear in pink. Blue represents mapped dark matter.

Webb observation of the Bullet Cluster shows many overlapping objects, including foreground stars, galaxies in galaxy clusters, and distorted background galaxies behind the galaxy clusters, set against the black background of space.

Bullet Cluster (NIRCam Image)

Webb captured the central region of the Bullet Cluster with its NIRCam (Near-Infrared Camera), revealing many more distant galaxies and faint objects, allowing a research team to refine the amount of mass in the two galaxy clusters.

A graphic labeled “James Webb Space Telescope; The Bullet Cluster, IE 0657-56.” Overlapping objects, including foreground stars, galaxies in galaxy clusters, and distorted background galaxies, are set against the black background of space. Two large blobs appear blue and pink at left and right.

Bullet Cluster (Webb and Chandra Compass Image)

Composite image of the Bullet Cluster combines near-infrared light from NASA’s James Webb Space Telescope, X-rays from NASA’s Chandra X-Ray Observatory in pink, and the inferred distribution of dark matter in blue). The two galaxy clusters appear within dashed circles.
