NGC 2903 - Galaxy in Leo

NGC 2903 is a barred spiral galaxy[1] located in the constellation Leo the Lion[1] approximately 30 million light years distant[1].  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].
