NGC 5455 is an emission nebula (HII region) located in Messier 101 (the Pinwheel Galaxy) [1] towards the constellation Ursa Major. Eight other regions of Messier 101 are listed in the New General Catalogue, namely NGC 5447, NGC 5449, NGC 5450, NGC 5451, NGC 5453, NGC 5458, NGC 5461 and NGC 5462. [2] Three of these regions were discovered by William Herschel (NGC 5447, NGC 5461 and NGC 5462) and the other six by Bindon Stoney. [3]
NGC 7012 is a large, bright elliptical galaxy located about 380 million light-years away from Earth in the constellation Microscopium. NGC 7012 was discovered by astronomer John Herschel on July 1, 1834.
NGC 7014 is an elliptical galaxy located about 210 million light-years away from Earth in the constellation Indus. NGC 7014 was discovered by English astronomer John Herschel on October 2, 1834.
NGC 7059 is a nearby spiral galaxy located about 70 million light-years away in the constellation of Pavo. NGC 7059 was discovered by astronomer John Herschel on July 22, 1835.
NGC 7060 is an intermediate spiral galaxy located about 200 million light-years away in the constellation of Microscopium. The spiral arms of NGC 7060 appear to overlap. NGC 7060 was discovered by astronomer John Herschel on September 2, 1836.
NGC 4489 is a dwarf elliptical galaxy located about 60 million light-years away in the constellation of Coma Berenices. It was discovered by astronomer William Herschel on March 21, 1784. NGC 4489 is a member of the Virgo Cluster.
NGC 4467 is an elliptical galaxy located about 78 million light-years away in the constellation of Virgo. NGC 4467 was discovered by astronomer Otto Struve on April 28, 1851. NGC 4467 is a companion of Messier 49 and is a member of the Virgo Cluster.
NGC 4476 is a lenticular galaxy located about 55 million light-years away in the constellation Virgo. NGC 4476 was discovered by astronomer William Herschel on April 12, 1784. The galaxy is a member of the Virgo Cluster.
NGC 4478 is an elliptical galaxy located about 50 million light-years away in the constellation Virgo. NGC 4478 was discovered by astronomer William Herschel on April 12, 1784. NGC 4478 is a member of the Virgo Cluster.
NGC 4482 is a dwarf elliptical galaxy located about 60 million light-years away in the constellation Virgo. NGC 4482 was discovered by astronomer William Herschel on March 15, 1784. It was rediscovered by astronomer Arnold Schwassmann on September 6, 1900 and was listed as IC 3427. It is a member of the Virgo Cluster.
NGC 4503 is a barred lenticular galaxy located around 41 to 74 million light-years away in the constellation Virgo. NGC 4503 was discovered by astronomer William Herschel on March 15, 1784. NGC 4503 is a member of the Virgo Cluster.
NGC 4544 is an edge-on spiral galaxy located about 52 million light-years away in the constellation Virgo. NGC 4544 was discovered by astronomer Edward Swift on April 27, 1887. NGC 4544 is a member of the Virgo Cluster.
NGC 6041 is a giant elliptical galaxy located about 470 million light-years away in the constellation Hercules. NGC 6041 has an extended envelope that is distorted towards the galaxy pair Arp 122. NGC 6041 is the brightest galaxy (BCG) in the Hercules Cluster. The galaxy was discovered by astronomer Édouard Stephan on June 27, 1870.
NGC 3312 is a large and highly inclined spiral galaxy located about 194 million light-years away in the constellation Hydra. The galaxy was discovered by astronomer John Herschel on March 26, 1835. It was later rediscovered by astronomer Guillaume Bigourdan on February 26, 1887. NGC 3312 was later listed and equated with IC 629 because the two objects share essentially the same celestial coordinates. NGC 3312 is the largest spiral galaxy in the Hydra Cluster and is also classified as a LINER galaxy.
NGC 997 is an interacting galaxy in the constellation of Cetus. The galaxy was discovered by Albert Marth on 10 November 1863. It has a regularly rotating central molecular gas disk, containing a black hole of between 4 x 107 and 1.8 x 109 solar masses. Its speed relative to the cosmological background is 6,270 ± 45 km/s, corresponding to a Hubble distance of 92.5 ± 6.5 Mpc (~302 million ly).
NGC 4999 is a barred spiral galaxy located in the constellation Virgo, first discovered February 24, 1786 by astronomer William Herschel. The galaxy is noted as a particularly bright ultraviolet light source – it is believed that its notable bar structure suppresses star formation, indicating this ultraviolet light may possibly be due to a quasi-stellar object.
NGC 855 is a star-forming dwarf elliptical galaxy located in the Triangulum constellation. The discovery and a first description was realized by William Herschel on 26th October 1786 and the findings made public through his Catalogue of Nebulae and Clusters of Stars, published the same year.
NGC 6365 is a pair of spiral galaxies in the constellation Draco. It consists of two galaxies, PGC 60174 to the south, and PGC 60171 to the north. These two galaxies are also designated respectively by the NASA/IPAC database as NGC 6365A and NGC 6365B. This pair of galaxies was discovered by German astronomer Lewis Swift in 1884.
NGC 5885 is an intermediate barred spiral galaxy located in the constellation Libra. Its speed relative to the cosmic microwave background is 2,185 ± 13 km/s, which corresponds to a Hubble distance of 32.3 ± 2.3 Mpc. NGC 5885 was discovered by German-British astronomer William Herschel in 1784.
