The structure of this remarkable spiral galaxy closely resembles our own Milky Way[2]. Although Charles Messier cataloged most of the bright galaxies visible from northern latitudes, he evidently missed this spectacular object[3]. The French astronomer De Vaucouleurs, and his associates, assigned the galaxy a classification of SAB(rs)be indicating a weaker bar (SAB) with a partial ring (rs)[2]. The Hubble Space Telescope has been used to study this bar structure and how it feeds material to form new stars near the center of the galaxy[2].
