NGC 6285 is an interacting spiral galaxy located in the constellation Draco. It is classified as S0-a in the galaxy morphological classification scheme and was discovered by the American astronomer Lewis A. Swift in 1886. [3] NGC 6285 is located at about 262 million light years away from Earth. NGC 6285 and NGC 6286 form a pair of interacting galaxies, with tidal distortions, categorized as Arp 293 in the Arp Atlas of Peculiar Galaxies [1] [2] [4]
NGC 520 is a pair of colliding spiral galaxies about 105 million light-years away in the constellation Pisces. They were discovered by astronomer William Herschel on 13 December 1784.
NGC 772 is an unbarred spiral galaxy approximately 130 million light-years away in the constellation Aries.
The Atlas of Peculiar Galaxies is a catalog of peculiar galaxies produced by Halton Arp in 1966. A total of 338 galaxies are presented in the atlas, which was originally published in 1966 by the California Institute of Technology. The primary goal of the catalog was to present photographs of examples of the different kinds of peculiar structures found among galaxies.
Arp 87 is a pair of interacting galaxies, NGC 3808A and NGC 3808B. They are situated in the Leo constellation. NGC 3808A, the brighter, is a peculiar spiral galaxy, while NGC 3808B is an irregular galaxy.
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 6286 is an interacting spiral galaxy located in the constellation Draco. It is designated as Sb/P in the galaxy morphological classification scheme and was discovered by the American astronomer Lewis A. Swift on 13 August 1885. NGC 6286 is located at about 252 million light years away from Earth. NGC 6286 and NGC 6285 form a pair of interacting galaxies, with tidal distortions, categorized as Arp 293 in the Arp Atlas of Peculiar Galaxies.
NGC 169 is a barred spiral galaxy located in the constellation Andromeda. It was discovered on September 18, 1857 by R. J. Mitchell.
NGC 191 is a spiral galaxy located in the constellation Cetus. It was discovered on November 28, 1785 by William Herschel.
NGC 523, also known as Arp 158, from the ARP catalog is a spiral galaxy located in the constellation Andromeda. It was discovered separately by William Herschel on 13 September 1784, and by Heinrich d'Arrest on 13 August 1862. d'Arrest's discovery was listed as NGC 523, while Herschel's was listed as NGC 537; the two are one and the same. John Dreyer noted in the New General Catalogue that NGC 523 is a double nebula.
NGC 7035 and NGC 7035A are a pair of interacting lenticular galaxies located around 400 to 430 million light-years away in the constellation of Capricornus. The main galaxy, NGC 7035 was discovered by astronomer Frank Muller in 1886.
NGC 7603 is a spiral Seyfert galaxy in the constellation Pisces. It is listed in the Atlas of Peculiar Galaxies. It is interacting with the smaller elliptical galaxy PGC 71041 nearby.
NGC 4647 is an intermediate spiral galaxy estimated to be around 63 million light-years away in the constellation of Virgo. It was discovered by astronomer William Herschel on March 15, 1784. NGC 4647 is listed along with Messier 60 as being part of a pair of galaxies called Arp 116; their designation in Halton Arp's Atlas of Peculiar Galaxies. The galaxy is located on the outskirts of the Virgo Cluster.
NGC 4633 is a spiral galaxy located about 70 million light-years away in the constellation of Coma Berenices. It is interacting with the nearby galaxy NGC 4634. NGC 4633 was discovered by astronomer Edward D. Swift on April 27, 1887. It was rediscovered on November 23, 1900, by astronomer Arnold Schwassmann and was later listed as IC 3688. NGC 4633 is a member of the Virgo Cluster.
NGC 6040 is a spiral galaxy located about 550 million light-years away in the constellation Hercules. NGC 6040 was discovered by astronomer Édouard Stephan on June 27, 1870. NGC 6040 is interacting with the lenticular galaxy PGC 56942. As a result of this interaction, NGC 6040's southern spiral arm has been warped in the direction toward PGC 56942. NGC 6040 and PGC 56942 are both members of the Hercules Cluster.
NGC 2936 is an interacting spiral galaxy located at a distance of 326 million light years, in the constellation Hydra. NGC 2936 is interacting with elliptical galaxy NGC 2937, located just beneath it. They were both discovered by Albert Marth on Mar 3, 1864. To some astronomers, the galaxy looks like a penguin or a porpoise. NGC 2936, NGC 2937, and PGC 1237172 are included in the Atlas of Peculiar Galaxies as Arp 142 in the category "Galaxy triplet".
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".
Arp 166 is a pair of interacting elliptical galaxies approximately 225 million light-years away from Earth in the constellation of Triangulum. The two galaxies, NGC 750 and NGC 751, are listed together as Arp 166 in the Atlas of Peculiar Galaxies.
NGC 750 is an elliptical galaxy approximately 225 million light-years away from Earth in the constellation of Triangulum. It forms a close pair of interacting galaxies together with the nearby NGC 751 galaxy. The pair is listed as Arp 166 in the Atlas of Peculiar Galaxies.
NGC 751 is an elliptical galaxy approximately 225 million light-years away from Earth in the constellation of Triangulum. It forms a close pair of interacting galaxies together with the nearby NGC 750 galaxy. The pair is listed as Arp 166 in the Atlas of Peculiar Galaxies.
NGC 7838 is a spiral or lenticular galaxy located about 500 million light-years away in the constellation of Pisces. The galaxy was discovered by astronomer Albert Marth on November 29, 1864. NGC 7838 appears to interact with NGC 7837 forming Arp 246.
