This bizarre galaxy has an almost liquified appearance because it’s a terrific example of an Einstein ring, which is due to a phenomenon called gravitational lensing. The galaxy is not actually deformed, though. It just looks that way.
What we’re really seeing is a unique, lucky view of distant GAL-CLUS-022058s, which is far beyond the elliptical galaxy at the center of this shot. As the light from GAL-CLUS-02258s streams past the closer elliptical, the latter galaxy’s gravity bends in the path of the passing light, amplifying and distorting it into the view we see here.
