NGC 1189 is a barred spiral galaxy approximately 105 million light-years away from Earth in the constellation of Eridanus. [1] It was discovered by American astronomer Francis Leavenworth on December 2, 1885 with the 26" refractor at Leander McCormick Observatory. [3]
NGC 1189 has extended clumpy star formation throughout its spiral arms with remarkably little associated stellar light, which is striking in the color images. [4]
Together with NGC 1190, NGC 1191, NGC 1192 and NGC 1199 it forms Hickson Compact Group 22 (HCG 22) galaxy group. [5] Although they are considered members of this group, NGC 1191 and NGC 1192 are in fact background objects, since they are much further away compared to the other members of this group. [4]
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.
NGC 3190 is a spiral galaxy with tightly wound arms and lying in the constellation Leo. It was discovered by William Herschel in 1784. NGC 3190 is member of Hickson 44 galaxy group, estimated at around 80 million light years away, and consisting of four galaxies in a tight group - NGC 3193 is fairly featureless, NGC 3187 is a dim but striking spiral galaxy and NGC 3185 has a barred spiral structure with an outer ring. 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 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 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 starbust phase. The galaxies are classed as Wolf–Rayet galaxies due to their high content of rare Wolf–Rayet stars.
NGC 493, also occasionally referred to as PGC 4979 or GC 281, is a barred spiral galaxy in the constellation Cetus. It is located approximately 90 million light-years from Earth and was discovered on December 20, 1786 by astronomer William Herschel. It was later also observed by his son, John Herschel. John Dreyer, creator of the New General Catalogue, described the galaxy as "very faint, large, much extended 60°" with "a little brighter middle".
NGC 494, also occasionally referred to as PGC 5035 or GC 282, is a barred spiral galaxy in the constellation Pisces. It is located approximately 227 million light-years from Earth and was discovered on 22 November 1827 by astronomer John Herschel. John Dreyer, creator of the New General Catalogue, described the galaxy as "very faint, pretty large, extended, 3 faint stars to south".
NGC 4516 is a barred spiral galaxy located about 55 million light-years away in the constellation Coma Berenices. NGC 4516 was discovered by astronomer William Herschel on April 8, 1784. NGC 4516 is a member of the Virgo Cluster.
NGC 1510 is a dwarf lenticular galaxy approximately 38 million light-years away from Earth in the constellation of Horologium. It was discovered by John Herschel on December 4, 1836.
NGC 497 is a barred spiral galaxy approximately 336 million light-years away from Earth in the constellation of Cetus. It was discovered by French astronomer Édouard Stephan on November 6, 1882.
NGC 1019 is a barred spiral galaxy approximately 316 million light-years away from Earth in the constellation of Cetus. It was discovered by French astronomer Édouard Stephan on December 1, 1880 with the 31" reflecting telescope at the Marseille Observatory.
NGC 1426 is an elliptical galaxy approximately 59 million light-years away from Earth in the constellation of Eridanus. It was discovered by William Herschel in December 9, 1784.
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 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 1436 is a barred spiral galaxy approximately 58 million light-years away from Earth in the constellation of Eridanus. It is a member of the Fornax I cluster.
NGC 1262 is a barred spiral galaxy located in the constellation Eridanus. NGC 1262 is the most distant object in the New General Catalogue lying about 1.5 billion light-years away from Earth. NGC 1262 is also a large galaxy with a diameter of about 380,000 light-years making it nearly four times larger than the Milky Way. It was discovered by astronomer Francis Leavenworth on November 12, 1885.
NGC 542 is a spiral galaxy in the constellation Andromeda, which is approximately 215 million light years from the Milky Way. Together with the galaxies NGC 529, NGC 531, and NGC 536, it forms the Hickson Compact Group 10, abbreviated HCG 10. It was discovered by Irish astronomer R.J. Mitchell in 1885.
NGC 531 is a barred spiral galaxy in the constellation Andromeda with a visual magnitude of 10.51. It is a distance of 65.7 Mpc from the Sun. It is a member of the Hickson Compact Group HCG 10, and is interacting with the other members of the group.
NGC 5910 is an elliptical galaxy located about 540 million light-years away in the constellation Serpens. It was discovered by astronomer William Hershel on April 13, 1785. NGC 5910 is also a strong radio source with a conspicuous nuclear jet.
