The inset in this image obtained with the Hubble Space Telescope shows that the brightest galaxy in group 3 has also a double nucleus. Thus, these galaxies are currently in the process of merging. This discovery provides unique and powerful validation of hierarchical formation as manifested in both galaxy and cluster assembly.Credit:
