| Description | The long axis of this galaxy is oriented from SE (upper left) to NW (lower right). I suppose you could describe it as a barred spiral, but in a "normal" barred galaxy you'd expect a single, central bright nucleus, whereas Arp 210 exhibits 5 bright spots within the "bar". Three are in a line close to the SE end. The fourth is rotated SSE from the third spot. The fifty, final bright spot is close to the NW end, continuing the line of the first three after a long gap. The central bulge appears slightly bent on the z axis, with a slight kink -- down and up -- at the second bright spot, and a distinct bend between the third and the final spot. The NW (lower right) hemisphere disk appears thick and intact. The SE hemisphere appears to have been disrupted. Irregular indeed! It certainly gives the impression of a spiral galaxy that has incompletely absorbed a number of smaller galaxies. |
