Friday Galactic Blogging

Another beautiful example of the effect of close gravitational interactions and the seemingly infinite variations in galactic structure that can result. This is AM 0644-741 (the "AM" designation is new to me.) One of a class of "ring galaxies," it is officially a lenticular galaxy. It is about 300 million light away in the southern constellation Dorado. It's an APOD image, and, as always, clicking through is rewarded with additional information and higher resolution views.
