X-ray and Optical Image of Bullet Cluster

Caption

This view of the Bullet Cluster is a combination of X-rays from Chandra (red) and optical data from the Hubble and Magellan telescopes (yellow). Scientists have examined this system with Chandra and Compton to look for evidence of antimatter that may be found in X-ray and gamma ray emission. The results did not reveal the signature for antimatter, meaning that if it is there, antimatter is less than 3 parts per million in this system.
