| Notes | This galaxy is a fine example of an edge-on spiral type. Although previously classified as a Sb spiral, current research would indicate that it is actually a SBb barred spiral based on studies of the kinematics of molecular gas in its inner regions. It's one of the closer galaxies to us at an estimated distance of about 10 million light years. Close investigation of the above image will reveal several small, faint background galaxies across the field of view. |
