Seyfert's Sextet is a group of galaxies about 190 million light-years away in the constellation Serpens. The group appears to contain six members, but one of the galaxies, NGC 6027d, is a background object and another "galaxy," NGC 6027e, is actually a part of the tail from galaxy NGC 6027. The gravitational interaction among these galaxies should continue for hundreds of millions of years. Ultimately, the galaxies will merge to form a single giant elliptical galaxy.
HCG 87 is a compact group of galaxies listed in the Hickson Compact Group Catalogue. This group is about 400 million light-years away in the constellation Capricornus. The group distinguishes itself as one of the most compact groups of galaxies, hosting two active galactic nuclei and a starburst among its three members, all of which show signs of interaction. This interaction, which astronomers have called visually, and scientifically, intriguing is being examined to understand the influence of active nuclei on star formation histories.
NGC 6744 is an intermediate spiral galaxy about 30 million light-years away in the constellation Pavo (Peacock). It is considered as a Milky Way mimic in the immediate vicinity, displaying flocculent (fluffy) arms and an elongated core. It also has at least one distorted companion galaxy superficially similar to one of the Magellanic Clouds. It was discovered from Parramatta in Australia by Scottish astronomer James Dunlop on 30 June 1826.
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.
NGC 145, also known as Arp 19, is a barred spiral galaxy in Cetus, notable for its three spiral arms.
UGC 2140 is an irregular galaxy in the constellation Aries. It was thought to be a compact group of galaxies, catalogued as HCG 18, but in 1999 the object was found to be a single galaxy with multiple star-forming regions.
NGC 14 is an irregular galaxy in the Pegasus constellation. It was included in Halton Arp's Atlas of Peculiar Galaxies, under the section "Galaxies with the appearance of fission," since the irregular appearance of this galaxy causes it to look like it is coming apart. It was discovered on September 18, 1786, by William Herschel.
Arp 272 is a pair of interacting galaxies consisting of the two spiral galaxies NGC 6050 (left) and IC 1179 (right). Arp 272 lies around 450 million light years from Earth in the constellation of Hercules. The galaxies are part of the Hercules Cluster, which is itself part of the CfA2 Great Wall.
NGC 5566 is a barred spiral galaxy in the constellation Virgo, which is approximately 66 million light years away from Earth. The galaxy is the biggest in the constellation Virgo, stretching nearly 150,000 light years in diameter. The galaxy NGC 5566 was discovered on 30 April 1786 by the German-British astronomer William Herschel. It is included in Halton Arp's Atlas of Peculiar Galaxies. It is a member of the NGC 5566 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.
NGC 3185 is a spiral galaxy located 20.4 Mpc away in the Leo constellation. NGC 3185 is a member of a four-galaxy group called HCG 44. It is also a member of the NGC 3190 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.
NGC 3718, also called Arp 214, is a galaxy located approximately 52 million light years from Earth in the constellation Ursa Major. It is either a lenticular or spiral galaxy.
NGC 201 is a spiral galaxy in the constellation of Cetus. It is one of the group members of HCG 7, with the other group members NGC 192, NGC 196, and NGC 197. It was discovered on December 28, 1790 by William Herschel.
NGC 148 is a lenticular galaxy located in the constellation Sculptor. It is about 40,000 light years across. It is in a group of three galaxies along with MCG-5-2-16 and IC 1555. It is a Shapley-Ames galaxy.
NGC 1741 is a distant pair of interacting galaxies in the Eridanus constellation. It was discovered on 6 January 1878 by French astronomer Édouard Stephan. As a result of the collision, the galaxies are in a rapid starburst phase. The galaxies are classed as Wolf–Rayet galaxies due to their high content of rare Wolf–Rayet stars.
NGC 1190 is a lenticular galaxy approximately 109 million light-years away from Earth in the constellation of Eridanus. It was discovered by American astronomer Francis Leavenworth on December 2, 1885 with the 26" refractor at Leander McCormick Observatory.
NGC 1189 is a barred spiral galaxy approximately 105 million light-years away from Earth in the constellation of Eridanus. It was discovered by American astronomer Francis Leavenworth on December 2, 1885 with the 26" refractor at Leander McCormick Observatory.
NGC 1191 is a lenticular galaxy approximately 406 million light-years away from Earth in the constellation of Eridanus. It was discovered by American astronomer Francis Leavenworth on December 2, 1885 with the 26" refractor at Leander McCormick Observatory.
NGC 1199 is an elliptical galaxy approximately 107 million light-years away from Earth in the constellation of Eridanus. It was discovered by William Herschel on December 30, 1785.
NGC 1192 is a lenticular galaxy approximately 417 million light-years away from Earth in the constellation of Eridanus. It was discovered by American astronomer Francis Leavenworth on December 2, 1885 with the 26" refractor at Leander McCormick Observatory.
NGC 3193 is an elliptical galaxy in the constellation Leo. The galaxy lies about 90 million light years away from Earth, which means, given its apparent dimensions, that NGC 3193 is approximately 80,000 light years across. It was discovered by William Herschel on March 12, 1784.
