MPEG This is a sequence of images of the galaxy cluster 1E 0657-56, also known as the bullet cluster. The optical image from the Magellan and the Hubble Space Telescope shows galaxies in orange and white. Hot gas, which contains the bulk of the normal matter in the cluster, is shown by the Chandra X-ray image (pink). Gravitational lensing, the distortion of background images by mass in the cluster, reveals the mass of the cluster is dominated by dark matter (blue). This is the first clear separation between normal and dark matter. [Runtime: 0:15]
