NGC 1165 is a barred spiral galaxy located in the constellation Fornax. It lies approximately 230 million light-years away from Earth and was discovered by astronomer John Herschel in 1835. [2]
NGC 1165 is classified as an SB(rs)b type galaxy, indicating that it is a barred spiral galaxy with a prominent central bar and slightly loose spiral arms. The galaxy spans approximately 1.8 × 1.4 arcminutes in the sky and features active star-forming regions within its spiral arms.
Observations using infrared and optical telescopes suggest the presence of a central supermassive black hole, a common feature in many barred spiral galaxies. The galaxy also exhibits regions of intense star formation, indicated by high concentrations of ionized hydrogen gas.
NGC 1165 was discovered by the British astronomer John Herschel during his observations of the southern skies in 1835. Since its discovery, it has been a subject of interest for astronomers studying barred spiral galaxies and galactic evolution.
NGC 1165 is situated in the constellation Fornax and is approximately 230 million light-years away from the Milky Way. Its radial velocity has been measured at around 4921 km/s, indicating its movement relative to our galaxy.
Barred spiral galaxies like NGC 1165 provide valuable insight into galactic dynamics and evolution. The study of such galaxies helps astronomers understand the role of bars in driving star formation and the distribution of interstellar matter.
NGC 3109 is a small barred Magellanic type spiral or irregular galaxy around 4.35 Mly away in the direction of the constellation of Hydra. NGC 3109 is believed to be tidally interacting with the dwarf elliptical galaxy Antlia Dwarf. It was discovered by John Herschel on March 24, 1835 while he was in what is now South Africa.
NGC 1365, also known as the Fornax Propeller Galaxy or the Great Barred Spiral Galaxy, is a double-barred spiral galaxy about 56 million light-years away in the constellation Fornax. It was discovered on 2 September 1826 by Scottish astronomer James Dunlop.
NGC 1097 is a barred spiral galaxy about 45 million light years away in the constellation Fornax. It was discovered by William Herschel on 9 October 1790. It is a severely interacting galaxy with obvious tidal debris and distortions caused by interaction with the companion galaxy NGC 1097A.
NGC 2997 is a face-on unbarred spiral galaxy about 40 million light-years away in the faint southern constellation of Antlia. It was discovered March 4, 1793 by German-born astronomer William Herschel. J. L. E. Dreyer described it as, "a remarkable object, very faint, very large, very gradually then very suddenly bright middle and 4 arcsec nucleus. This is the brightest galaxy of the NGC 2997 group of galaxies, and was featured on the cover of the first edition of Galactic Dynamics by James Binney and Scott Tremaine.
NGC 1232, also known as the Eye of God Galaxy is an intermediate spiral galaxy about 60 million light-years away in the constellation Eridanus. It was discovered by German-British astronomer William Herschel on 20 October 1784.
NGC 4314 is a barred spiral galaxy approximately 53 million light-years away in the northern constellation of Coma Berenices. It is positioned around 3° to the north and slightly west of the star Gamma Comae Berenices and is visible in a small telescope. The galaxy was discovered by German-born astronomer William Herschel on March 13, 1785. It was labelled as peculiar by Allan Sandage in 1961 because of the unusual structure in the center of the bar. NGC 4314 is a member of the Coma I group of galaxies.
NGC 1350 is a spiral galaxy located 87 million light years away in the southern constellation Fornax. It was discovered by Scottish astronomer James Dunlop on 24 November 1826.
NGC 7098 is a doubled barred spiral galaxy located about 95 million light-years away from Earth in the constellation of Octans. NGC 7098 has an estimated diameter of 152,400 light-years. NGC 7098 was discovered by astronomer John Herschel on September 22, 1835.
NGC 4440 is a barred spiral galaxy located about 55 million light-years away in the constellation of Virgo. NGC 4440 was discovered by astronomer William Herschel on April 17, 1784. It is a member of the Virgo Cluster.
NGC 6028 is a barred lenticular galaxy and a ring galaxy located about 200 million light-years away in the constellation Hercules. Ring galaxies such as NGC 6028 are also known as Hoag-type galaxies as they may have a resemblance to the prototype, Hoag's Object. NGC 6028 was discovered by astronomer William Herschel on March 14, 1784. It was then rediscovered by astronomer Guillaume Bigourdan on May 4, 1886.
NGC 824 is a barred spiral galaxy located in the constellation Fornax about 260 million light-years from the Milky Way. It was discovered by British astronomer John Herschel in 1837.
NGC 1484 is a barred spiral galaxy approximately 50 million light-years away from Earth in the constellation of Fornax. It was discovered by astronomer John Herschel on November 28, 1837. NGC 1484 is a member of the Fornax cluster.
NGC 4999 is a barred spiral galaxy located in the constellation Virgo, first discovered February 24, 1786 by astronomer William Herschel. The galaxy is noted as a particularly bright ultraviolet light source – it is believed that its notable bar structure suppresses star formation, indicating this ultraviolet light may possibly be due to a quasi-stellar object.
NGC 1616 is an intermediate spiral galaxy located around 213 million light-years away in the constellation Caelum. NGC 1616 was discovered on October 24th, 1835 by the astronomer John Herschel, and its diameter is 116,000 light-years across. NGC 1616 is not known to have much star-formation, and it is not known to have an active galactic nucleus.
NGC 633 is a large barred spiral galaxy located in the constellation Sculptor. Its speed relative to the cosmic microwave background is 4,979 ± 18 km/s, which corresponds to a Hubble distance of 73.4 ± 5.2 Mpc. NGC 633 was discovered by British astronomer John Herschel in 1834.
NGC 1385 is a barred spiral galaxy in the constellation of Fornax. Its velocity with respect to the cosmic microwave background is 1381 ± 9 km/s, which corresponds to a Hubble distance of 20.37 ± 1.43 Mpc. In addition, 30 non redshift measurements give a distance of 15.999 ± 12.131 Mpc. The galaxy was discovered by German-British astronomer William Herschel on 17 November 1784.
