Description

At first glance, this galaxy looks unimpressive in this photograph. (Its that bright elongated blob near the center.) The galaxy is quite bright, with a nearly (but not-quite) star-like drop in brightness at its outer edge. However, it clearly has a double nucleus, causing the elongation. Both nuclei appear to be truly galactic in nature as opposed to a star masquerading as a second nucleus. There is only the slightest hint of faint, asymmetric extensions to the north and south, and perhaps a small detached segment to the lower right (which could perhaps be a separate, fainter galaxy?). The double nuclei and faint asymmetric extensions seems indicative of colliding galaxies. Further digging reveals that this galaxy may be a polar-ring galaxy. I really want to see a Hubble Space Telescope image of this! Just to the north of this galaxy lies the edge-on galaxy PGC 1514392 (which was the unintended target of the image I took just before this one).
