Gioiello (galaxy cluster)

The XDCPJ0044.0-2033 (Gioello) galaxy cluster at redshift z=1.579 was discovered in the archive of the XMM-Newton mission, as part of the XMM-Newton Distant Cluster Project (XDCP) and first published by Santos et al. 2011.^[1] Gioiello is the most distant massive galaxy cluster that has been found and studied today. This massive galaxy cluster contains 400 trillion times the mass of the Sun and is located 9.6 billion light years away from Earth. The name Gioiello, meaning "jewel" in Italian, was given to this massive galaxy cluster because an image of the cluster contains many beautiful pink, purple, and red sparkling colors from the hot X-ray–emitting gas and other star-forming galaxies within the cluster.
