... In the nuclear area of the galaxy within the ring, the nucleus appears elongated, and a fainter 3rd star-like component is discernable. ... The 'yellowy' halo about the off-centre nucleus of the ring galaxy is likely composed of redder stars, while the color-neutral nucleus doesn't appear distinctly different in color than either of the ring 'impactor' candidates at bottom center and top right of the picture. ... If so then why are the bright regions within the ring apparently color neutral? ...
