Floating Silver Coin
Known as Sculptor Galaxy, and catalogued as NGC 253, this galaxy is home of very massive star clusters: the biggest of them of about 1.4e7 solar masses. I like this galaxy not only because of its looks, but also because it hosts a lot of Wolf-Rayet stars, my favorite kind of star.
