NGC 701 is a spiral galaxy with a high star formation rate in the constellation Cetus. It is estimated to be 86 million light years from the Milky Way and has a diameter of approximately 65,000 light years. The object was discovered on January 10, 1785 by the German-British astronomer William Herschel. [6] [7] [8]
NGC 2715 is an intermediate spiral galaxy in the constellation Camelopardalis. It was discovered in 1871 by Alphonse Borrelly. It is an intermediate spiral galaxy that is 4.9 arcminutes wide.
NGC 2787 is a barred lenticular galaxy approximately 24 million light-years away in the northern constellation of Ursa Major. It was discovered on December 3, 1788 by German-born astronomer William Herschel. J. L. E. Dreyer described it as, "bright, pretty large, a little extended 90°, much brighter middle, mottled but not resolved, very small (faint) star involved to the southeast". The visible galaxy has an angular size of 2′.5 × 1′.5 and an apparent visual magnitude of 11.8.
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 4605 is a dwarf barred spiral galaxy in the constellation Ursa Major, located at a distance of 18.1 ± 0.3 megalight-years from the Milky Way. Physically it is similar in size and in B-band absolute magnitude to the Large Magellanic Cloud. It is a member of the M81 Galaxy Group, along with Messier 81 and Messier 101.
NGC 6263 is an elliptical galaxy in the constellation Hercules. It was discovered by Albert Marth on June 28, 1864.
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.
NGC 5665 is a spiral galaxy in the constellation of Boötes.
NGC 5490 is a radio galaxy in the constellation Boötes.
NGC 3539 is a lenticular galaxy in the constellation Ursa Major. It was discovered in April 1831 by John Herschel. It is a member of the galaxy cluster Abell 1185.
NGC 41 is a spiral galaxy located in the constellation Pegasus. It is located about 290 million light-years away from the Sun. It was discovered on October 30, 1864, by the astronomer Albert Marth.
NGC 4866 is an unbarred lenticular galaxy located roughly 100 million light-years away in the constellation Virgo. It was first observed by British astronomer Sir William Herschel on January 14, 1787. It is a member of the Virgo Cluster.
NGC 100 is a galaxy located approximately 60 million light-years from the Solar System in the constellation Pisces. It has an apparent magnitude of 13.2. It was first discovered on 10 November 1885 by American astronomer Lewis Swift.
NGC 79 is an elliptical galaxy estimated to be about 270 million light-years away in the constellation of Andromeda. NGC 79 is its New General Catalogue designation. Its apparent magnitude is 14.9. It was discovered on 14 November 1884 by Guillaume Bigourdan.
NGC 4138 is the New General Catalogue identifier for a lenticular galaxy in the northern constellation of Canes Venatici. Located around 52 million light years from Earth, it spans some 2.1 × 1.3 arc minutes and has an apparent visual magnitude of 11.3. The morphological classification of NGC 4138 is SA0+(r), indicating it lacks a bar formation and has tightly wound spiral arms with a ring-like structure around the nucleus. It has no nearby companion galaxies.
NGC 4178 is the New General Catalogue identifier for a barred spiral galaxy in the equatorial constellation of Virgo. It was discovered April 11, 1825 by English astronomer John Herschel. Located some 43.8 million light years away, this galaxy spans 2.3 × 0.4 arc minutes and is seen at a low angle, being inclined by 77° to the line of sight from the Earth. The morphological classification of NGC 4178 is SB(rs)dm, indicating that it has a bar feature at the core, and, per the '(rs)', has traces of a ring-like structure surrounding the bar. The 'dm' suffix indicates the spiral arms are diffuse, broken, and irregular in appearance with no bulge at the nucleus. This galaxy is a member of the Virgo Cluster, which is the richest nearby group of galaxies outside the Local Group and forms the core of the Virgo Supercluster.
NGC 4203 is the New General Catalogue identifier for a lenticular galaxy in the northern constellation of Coma Berenices. It was discovered on March 20, 1787 by English astronomer William Herschel, and is situated 5.5° to the northwest of the 4th magnitude star Gamma Comae Berenices and can be viewed with a small telescope. The morphological classification of NGC 4203 is SAB0−, indicating that it has a lenticular form with tightly wound spiral arms and a weak bar structure at the nucleus.
NGC 5470 is an edge-on spiral galaxy located between 43 and 68 million light-years away in the constellation Virgo. It was discovered by astronomer John Herschel in 1830. It is a member of the Virgo III Groups, a series of galaxies and galaxy clusters strung out to the east of the Virgo Supercluster of galaxies.
NGC 770 is an elliptical galaxy in the constellation Aries. It is around 120 million light years from the Milky Way and has a diameter of around 36,000 ly. NGC 770 is gravitationally linked to NGC 772. The galaxy was discovered on November 3, 1855 by RJ Mitchell.
NGC 2227 is a barred spiral galaxy with a morphological type of SB(rs)c located in the direction of the Canis Major constellation. It was discovered on January 27, 1835, by John Herschel.
NGC 546 is a barred spiral galaxy about 270 million light years away from Earth and located in the constellation Sculptor. The largest diameter is 1.40 and the smallest is 0.5 angular minutes. The first discovery was made by John Frederick William Herschel on 23 October 1835.
