NGC 5278 is a spiral galaxy in the constellation Ursa Major. It was discovered by German-British astronomer William Herschel in 1789. [1]
NGC 5278 is in gravitational interaction with the galaxy NGC 5279. This pair of galaxies appears in the Halton Arp's Atlas of Peculiar Galaxies under the symbol Arp 239. The luminosity class of NGC 5278 is II. [2] The nucleus of this galaxy presents a burst of star formation (SBNG starburst nucleus galaxies) and it is an active Seyfert 2 type galaxy. In addition, NGC 5278 is possibly a LINER galaxy, a galaxy whose nucleus presents an emission spectrum characterized by broad lines of weakly ionized atoms. [3] NGC 5278 is also a galaxy whose core shines in the ultraviolet spectrum. It is listed in the Markarian catalog under the reference Mrk 271 (MK 271). [4]
Two supernovae have been observed in NGC 5278: SN 2001ai (type Ic, mag. 17.6) [5] and SN 2019cec (type II, mag. 18.26a). [6]
The Antennae Galaxies are a pair of interacting galaxies in the constellation Corvus. They are currently going through a starburst phase, in which the collision of clouds of gas and dust, with entangled magnetic fields, causes rapid star formation. They were discovered by William Herschel in 1785.
NGC 772 is an unbarred spiral galaxy approximately 106 million light-years away in the constellation Aries. It was discovered on 29 November 1785 by German-British astronomer William Herschel.
NGC 2207 and IC 2163 are a pair of colliding spiral galaxies about 80 million light-years away in the constellation Canis Major. Both galaxies were discovered by John Herschel in 1835.
Arp 299 is a pair of colliding galaxies approximately 134 million light-years away in the constellation Ursa Major. Both of the galaxies involved in the collision are barred irregular galaxies. NGC 3690 was discovered on 18 March 1790 by German-British astronomer William Herschel.
NGC 935 and IC 1801 are a pair of interacting galaxies within the Aries constellation. They were discovered on 18 September 1885 by Lewis Swift. NGC 935 is the northern member of the pair, and IC 1801 is the southern. Together, they are listed in Halton Arp's Atlas of Peculiar Galaxies as Arp 276, as an example of interacting galaxies.
Arp 271 is a pair of similarly sized interacting spiral galaxies, NGC 5426 and NGC 5427, in the constellation of Virgo. It is not certain whether the galaxies are going to eventually collide or not. They will continue interacting for tens of millions of years, creating new stars as a result of the mutual gravitational attraction between the galaxies, a pull seen in the bridge of stars already connecting the two. Located about 130 million light-years away, the Arp 271 pair is about 130,000 light-years across. It was originally discovered in 1785 by William Herschel. It is speculated, that the Milky Way will undergo a similar collision in about five billion years with the neighbouring Andromeda Galaxy, which is currently located about 2.6 million light-years away.
NGC 908 is an unbarred spiral galaxy in the constellation Cetus. It was discovered on 20 September 1786 by William Herschel. This galaxy is 56 million light years away from Earth. It is the main galaxy in the NGC 908 group, which also includes NGC 899, NGC 907, and IC 223.
IC 883 is an irregular galaxy that is about 321 million light years away from Earth. It is located in the constellation Canes Venatici. Its largest radius is 1.4, and smallest 0.7 angular minutes .[b] It was discovered by Rudolf Ferdinand Spitaler on May 1 1891.
NGC 213 is a barred spiral galaxy located in the constellation Pisces. It was discovered on October 14, 1784, by William Herschel.
NGC 3147 is a spiral galaxy located in the constellation Draco. It is located at a distance of about 130 million light years from Earth, which, given its apparent dimensions, means that NGC 3147 is about 140,000 light years across. It was discovered by William Herschel on April 3, 1785.
NGC 3313 is a large barred spiral galaxy located about 55 megaparsecs away in the constellation Hydra. It was discovered by astronomer Ormond Stone in 1886 and is an outlying member of the Hydra Cluster.
NGC 5468 is an intermediate spiral galaxy located in the constellation Virgo. It is located at a distance of about 140 million light-years from Earth, which, given its apparent dimensions, means that NGC 5468 is about 110,000 light-years across. It was discovered by William Herschel on March 5, 1785.
NGC 5395 is an interacting spiral galaxy located at a distance of 160 million light years, but receding away from the Earth at 3511 kilometers per second, in the constellation Canes Venatici. It was discovered by William Herschel on May 16, 1787. NGC 5395 and NGC 5394 are included in the Atlas of Peculiar Galaxies as Arp 84 in the category "Spiral galaxies with large high surface brightness companions".
NGC 2300 is a lenticular galaxy in the constellation Cepheus. Its velocity with respect to the cosmic microwave background is 1876 ± 7 km/s, which corresponds to a Hubble distance of 90.2 ± 6.3 Mly (27.67 ± 1.94 Mpc). However, 11 non redshift measurements give a distance of 131.98 ± 21.75 Mly (40.464 ± 6.668 Mpc). The galaxy was discovered in 1871 by French astronomer Alphonse Borrelly using an 18 cm telescope.
NGC 819 is a spiral galaxy approximately 302 million light-years away from Earth in the constellation of Triangulum. It forms a visual pair with the galaxy NGC 816 5.7' WNW.
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 2935 is a large intermediate spiral galaxy located in the constellation Hydra. Its speed relative to the cosmic microwave background is 2,601 ± 23 km/s, which corresponds to a Hubble distance of 38.4 ± 2.7 Mpc. NGC 2935 was discovered by German-British astronomer William Herschel in 1786.
NGC 5876 is a barred spiral galaxy in the constellation of Boötes. Its velocity with respect to the cosmic microwave background is 3325 ± 5 km/s, which corresponds to a Hubble distance of 49.05 ± 3.43 Mpc. However, three non redshift measurements give a distance of 65.6 ± 0.346 Mpc. The galaxy was discovered by American astronomer Lewis Swift on 11 June 1885. Swift observed the galaxy again on August 27, 1888, and not realizing that he had already observed it, entered the galaxy into the Index Catalogue as IC 1111.
NGC 3362 is a intermediate spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 8676 ± 25 km/s, which corresponds to a Hubble distance of 127.97 ± 8.97 Mpc. However, three non redshift measurements give a distance of 95.8 ± 3.984 Mpc. The galaxy was discovered by German astronomer Albert Marth on 22 March 1865.
NGC 5605 is an intermediate spiral galaxy in the constellation of Libra. Its velocity with respect to the cosmic microwave background is 3635 ± 18 km/s, which corresponds to a Hubble distance of 174.9 ± 12.3 Mly (53.61 ± 3.76 Mpc). In addition, three non redshift measurements give a distance of 194.72 ± 0.68 Mly (59.700 ± 0.208 Mpc). The galaxy was discovered by German-British astronomer William Herschel on 11 May 1784.
