This NASA Hubble Space Telescope image showcases the galaxy cluster CL0016+1609, also known as MACS J0018.5+1626, which is very bright at X-ray wavelengths and has been extensively studied in X-ray and radio wavelengths. The X-ray observations indicate that this cluster is composed of two merging clusters along our line of sight.

This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensively studied clusters at X-ray and radio wavelengths. The X-ray observations of this cluster revealed that it is two clusters merging along our line of sight.
