NGC 4013 is an edge-on barred spiral galaxy about 55 million light-years away in the constellation Ursa Major. The disk of NGC 4013 shows a distinct "peanut"-shaped bulge in long exposure photographs that N-body computer simulations suggest is consistent with a stellar bar seen perpendicular to the line of sight.

A recent deep color image of NGC 4013 revealed a looping tidal stream of stars extending over 80 thousand light-years from the Galactic Center. This structure is thought to be the remnants of a smaller galaxy that was torn apart by tidal forces as it collided with NGC 4013. [5]

Supernova SN 1989Z was discovered on December 30, 1989 at apparent magnitude 12. [6]

NGC 4013 is a member of the Ursa Major Cluster. [7]

<span class="mw-page-title-main">NGC 2903</span> Spiral galaxy in the constellation Leo

NGC 2903 is an isolated barred spiral galaxy in the equatorial constellation of Leo, positioned about 1.5° due south of Lambda Leonis. It was discovered by German-born astronomer William Herschel, who cataloged it on November 16, 1784. He mistook it as a double nebula, as did subsequent observers, and it wasn't until the nineteenth century that the Third Earl of Rosse resolved into a spiral form. J. L. E. Dreyer assigned it the identifiers 2903 and 2905 in his New General Catalogue; NGC 2905 now designates a luminous knot in the northeastern spiral arm.

NGC 2976 is a peculiar dwarf galaxy in the northern circumpolar constellation of Ursa Major. It was discovered by German-born astronomer William Herschel on November 8, 1801, and catalogued as H I.285. J. L. E. Dreyer described it as, "bright, very large, much extended 152°, star involved". It is a member of the M81 Group and lies 1° 20′ to the southwest of Messier 81. The projected separation of this galaxy from the M81 Group is 190 kpc.

NGC 1134 is a spiral galaxy in the Aries constellation. It has a highly inclined disk, with respect to the line of sight from Earth. There is a weak outer extension of the spiral structure in this galaxy. It has been listed in the Arp Atlas of Peculiar Galaxies, under the "Galaxies with material ejected from nuclei" section. NGC 1134 is classified as a galaxy with reduced surface brightness, and it possesses a distinct bulge in its centre, as judged by photometric analysis. It has a small and distant companion about 7' to the south.
