X-ray, Optical & Lensing Map Images of Abell 2744
These images feature one of the most complicated and dramatic collisions between galaxy clusters ever seen. Known officially as Abell 2744, this system has been dubbed "Pandora's Cluster" because of the wide variety of different structures found. Data from Chandra show gas with temperatures of millions of degrees. Next is a map showing the total mass concentration (mostly dark matter) based on data from the Hubble Space Telescope, the Very Large Telescope (VLT), and the Subaru telescope. Optical data from HST and VLT also show the constituent galaxies of the clusters. Astronomers think at least four galaxy clusters coming from a variety of directions are involved with this collision.
