(PhysOrg.com) -- A team of scientists has studied the galaxy cluster Abell 2744, nicknamed Pandoras Cluster. They have pieced together the clusters complex and violent history using telescopes in space and on the ground, including ESOs Very Large Telescope and the Hubble Space Telescope. Abell 2744 seems to be the result of a simultaneous pile-up of at least four separate galaxy clusters and this complex collision has produced strange effects that have never been seen together before.
