Droplets of star formation and two merging galaxies in SDSS J1531+3414
This new NASA/ESA Hubble Space Telescope image shows two galaxies from the cluster SDSS J1531+3414.
The two galaxies have been found to be merging into one and a "chain" of young stellar superclusters are seen winding around the galaxies’ nuclei. The galaxies are surrounded by an egg-shaped blue ring caused by the immense gravity of the cluster bending light from other galaxies beyond it.
