NGC 277 is a lenticular galaxy located in the constellation Cetus. It was discovered on October 8, 1864, by the German astronomer Heinrich Louis d'Arrest. [2] The galaxy is situated near the celestial equator, making it observable from both the Northern and Southern Hemispheres at various times of the year. With an apparent B magnitude of 13, NGC 277 requires a telescope with an aperture of at least 10 inches (250 mm) for proper observation.
As a lenticular galaxy, NGC 277 exhibits characteristics between those of elliptical and spiral galaxies, featuring a prominent central bulge and a disk-like structure but lacking significant spiral arm features. Its precise distance from Earth is not well-documented in readily available sources, which is common for many galaxies cataloged in the 19th century. The galaxy's position and brightness make it a subject of interest for amateur astronomers equipped with sufficiently powerful telescopes.
For those interested in observing NGC 277, it is recommended to consult star charts and plan observations during times when Cetus is prominently positioned in the night sky, typically during the months of October through December. Due to its faintness, observing from a location with minimal light pollution will enhance visibility. [3]
NGC 4394 is a SBb barred spiral galaxy in the constellation Coma Berenices and is situated about 39.5 million light-years from Earth. It was discovered on 14 March 1784 by the German–British astronomer William Herschel. It is a presumed companion to the lenticular galaxy M85 / NGC 4382, which lies 8 arc minutes away. It is also a member of the Virgo Cluster.
NGC 7013 is a relatively nearby spiral or lenticular galaxy estimated to be around 37 to 41.4 million light-years away from Earth in the constellation of Cygnus. NGC 7013 was discovered by English astronomer William Herschel on July 17, 1784 and was also observed by his son, astronomer John Herschel on September 15, 1828.
NGC 487 is a barred spiral galaxy located about 250 million light-years away from Earth in the constellation Cetus. NGC 487's calculated velocity is 5949 km/s. NGC 487 was discovered by American astronomer Francis Leavenworth on November 28, 1885.
NGC 480 is a spiral galaxy located about 546 million light-years away from Earth in the constellation Cetus. NGC 480 was discovered by American astronomer Francis Leavenworth In 1886.
NGC 4623 is an edge-on lenticular or elliptical galaxy located about 54 million light-years away in the constellation of Virgo. NGC 4623 is classified as an E7, a rare type of "late" elliptical that represents the first stage of transition into a lenticular galaxy. NGC 4623 was discovered by astronomer William Herschel on April 13, 1784. NGC 4623 is a member of the Virgo Cluster.
NGC 4436 is a lenticular or dwarf elliptical galaxy located about 60 million light-years away in the constellation of Virgo. NGC 4436 was discovered by astronomer William Herschel on April 17, 1784. The galaxy 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 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 966 is an unbarred lenticular galaxy approximately 440 million light-years away from Earth in the constellation of Cetus. It was discovered by American astronomer Francis Preserved Leavenworth in 1886.
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 502, also occasionally referred to as PGC 5034 or UGC 922, is a lenticular galaxy in the constellation Pisces. It is located approximately 113 million light-years from the Solar System and was discovered on 25 September 1862 by German astronomer Heinrich Louis d'Arrest. When the Morphological Catalogue of Galaxies was published between 1962 and 1974, the identifications of NGC 502 and NGC 505 were reversed. In reality, NGC 502 is equal to MGC +01-04-041 and not MCG +01-04-043 as noted in the catalogue.
NGC 1262 is a barred spiral galaxy located in the constellation Eridanus. NGC 1262 is about 686 million light-years from Earth. This galaxy was formerly believed to be the most distant object in the New General Catalogue, however, in 2023 using data from Ann Isaacs from the University of Minnesota, Stephen Odewahn from the McDonald Observatory used new radial velocity calculations which placed NGC 1262 nowhere near the most distant NGC galaxy. 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 3558 is an elliptical or a lenticular galaxy located 440 million light-years away in the constellation Ursa Major. It was discovered by the astronomer Heinrich d'Arrest on April 15, 1866. It is a member of the galaxy cluster Abell 1185 and is classified as a LINER galaxy.
NGC 998 is a spiral galaxy in the constellation Cetus. It is estimated to be 294 million light years from the Milky Way and has a diameter of approximately 90,000 ly. Together with NGC 997, it forms a gravitationally bound pair of galaxies. NGC 998 was discovered by astronomer Albert Marth on 10 November 1863 using a 48-inch telescope.
NGC 734 is a lenticular galaxy with a central bar in the constellation Cetus, which is about 538 million light years from the Milky Way. It was discovered on November 9, 1885, by the American astronomer Francis Preserved Leavenworth.
NGC 548, also occasionally referred to as PGC 5326 or UGC 1010, is an elliptical galaxy in the constellation Cetus. It is located approximately 244 million light-years from the Solar System and was discovered on 2 November 1867 by American astronomer George Mary Searle.
NGC 2012 is a large lenticular galaxy in the Constellation Mensa. It was discovered by John Herschel in 1836. With its distance from the Earth being over 236 million light years, NGC 2012 is not visible to the naked eye, and a large telescope is needed. A probe has never been sent out to study the galaxy.
NGC 4825 is a lenticular galaxy located around 230 million light-years away in the constellation Virgo. NGC 4825 was discovered on March 27th, 1786 by the astronomer William Herschel, and its diameter is 133,000 light-years across. NGC 4825 is not known to have much star-formation, and it does not have an active galactic nucleus.
NGC 1009 is a large spiral galaxy in the constellation Cetus. Its speed relative to the cosmic microwave background is 5,594 ± 24 km/s, which corresponds to a Hubble distance of 82.5 ± 5.8 Mpc. NGC 1009 was discovered by American astronomer Edward Swift in 1886. The luminosity class of NGC 1009 is II and it has a broad HI line. To date, five non-redshift measurements yield a distance of 91.940 ± 3.045 Mpc, which is just outside the distance values of Hubble.
NGC 3843 is a lenticular galaxy located in the constellation Virgo, first cataloged by the German-British astronomer William Herschel. Classified as type S0-a, it shows characteristics intermediate between elliptical and spiral galaxies, without prominent spiral arms. The galaxy has a visual magnitude of approximately 13.5, making it relatively faint and challenging to observe without larger telescopes. With an angular size of about 0.9 by 0.4 arcminutes, NGC 3843 is around 270 million light-years from Earth, determined by its redshift of 0.0197.
