... Credit Copyright: Robert Gendler Explanation: Big, bright, and beautiful, spiral galaxy M83 lies a mere twelve million light-years away, near the southeastern tip of the very long constellation Hydra . Prominent spiral arms traced by dark dust lanes and blue star clusters lend this galaxy its popular name, The Southern Pinwheel. But reddish star forming regions that dot the sweeping arms highlighted in this sparkling color composite also suggest another nickname, The Thousand-Ruby Galaxy. ...

... 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? ...
