Abell 2255 (often shortened to A2255) is a rich galaxy cluster located at a relatively nearby distance of redshift z=0.0806 in the Constellation of Draco. It contains some 300-500 galaxies. It has a radius that spans 16.3 million light years. The cluster contains a dense environment with a chaotic intracluster medium (ICM) that contains shocks, turbulent filaments, intense magnetic fields and other phenomenon. X-ray observations of the temperature asymmetries of the clusters intracluster medium (ICM) from XMM-newton indicate that it had recently gone through a merger event with another galaxy cluster around 0.15 billion years ago.
