NGC 7499 is an unbarred lenticular galaxy [3] within the constellation Pisces. NGC 7499 is its New General Catalogue designation. It was discovered on September 2, 1864 by the astronomer Albert Marth. [5]
On 7 December 1986, a supernova was discovered within NGC 7499 and was subsequently designated SN 1986M (type Ib, mag. 16.5). [6] [7]
Messier 99 or M99, also known as NGC 4254 or St. Catherine's Wheel, is a grand design spiral galaxy in the northern constellation Coma Berenices approximately 15,000,000 parsecs from the Milky Way. It was discovered by Pierre Méchain on 17 March 1781. The discovery was then reported to Charles Messier, who included the object in the Messier Catalogue of comet-like objects. It was one of the first galaxies in which a spiral pattern was seen. This pattern was first identified by Lord Rosse in the spring of 1846.
NGC 5886 is an +14 magnitude elliptical galaxy in the constellation Boötes. It was originally discovered by John Herschel on 13 May 1828 with an 18.7 inches (470 mm) reflector.
NGC 7315 is a lenticular galaxy in the constellation of Pegasus. It was discovered on 11 September 1872 by Édouard Stephan. It was described as "very faint, extremely small, round, brighter middle" by John Louis Emil Dreyer, the compiler of the New General Catalogue.
NGC 5754 is a barred spiral galaxy located 218 million light years away in the constellation Boötes. It was discovered by German-British astronomer William Herschel on 16 May 1787.
NGC 4780 is an intermediate spiral galaxy within the constellation Virgo. It is located about 166 million light-years away from the Sun. It was discovered in 1880 by the astronomer Wilhelm Tempel.
NGC 42 is a lenticular galaxy in the Pegasus constellation. It was discovered on October 30, 1864, by the German astronomer Albert Marth. It may be gravitationally interacting with the nearby NGC 41.
NGC 3258 is an elliptical galaxy in the constellation Antlia. It is a member of the Antlia Cluster, which lies about 40.7 megaparsecs away. It was discovered on May 2, 1834 by John Herschel.
NGC 6850 is a barred lenticular galaxy in the constellation Telescopium, discovered by John Herschel on 9 June 1836.
NGC 4866 is an unbarred lenticular galaxy located roughly 100 million light-years away in the constellation Virgo. It was first observed by British astronomer Sir William Herschel on January 14, 1787. It is a member of the Virgo Cluster.
NGC 3359 is a barred spiral galaxy located 59 million light-years from Earth, in the constellation of Ursa Major. It was discovered on November 28, 1793, by the astronomer William Herschel. The central bar is approximately 500 million years old.
NGC 113 is an unbarred lenticular galaxy located in the constellation Cetus. It was discovered by German astronomer, Ernst Wilhelm Leberecht Tempel, on August 27, 1876.
NGC 124 is a spiral galaxy in the constellation Cetus. It was discovered by Truman Henry Safford on September 23, 1867. The galaxy was described as "very faint, large, diffuse, 2 faint stars to northwest" by John Louis Emil Dreyer, the compiler of the New General Catalogue.
NGC 5470 is an edge-on spiral galaxy located between 43 and 68 million light-years away in the constellation Virgo. It was discovered by astronomer John Herschel in 1830. It is a member of the Virgo III Groups, a series of galaxies and galaxy clusters strung out to the east of the Virgo Supercluster of galaxies.
NGC 1573 is an elliptical galaxy in the constellation of Camelopardalis. It was discovered on 1 August 1883 by Wilhelm Tempel. It was described as "very faint, small" by John Louis Emil Dreyer, the compiler of the New General Catalogue. It is located about 190 million light-years away.
NGC 5559 is a barred spiral galaxy, located 240 million light-years away in the constellation of Boötes. It was discovered on April 10, 1785, by the astronomer William Herschel.
NGC 3697 is a spiral galaxy in the constellation of Leo. It was discovered on 24 February 1827 by John Herschel. It was described as "extremely faint, very small, extended 90°" by John Louis Emil Dreyer, the compiler of the New General Catalogue. It is a member of HCG 53, a compact group of galaxies.
NGC 2227 is a barred spiral galaxy with a morphological type of SB(rs)c located in the direction of the Canis Major constellation. It was discovered on January 27, 1835, by John Herschel.
NGC 644 is a barred spiral galaxy in the constellation Phoenix in the southern sky. It is estimated to be 270 million light-years from the Milky Way and has a diameter of approximately 130,000 light-years. Together with NGC 641, it probably forms a gravitationally bound pair of galaxies. The object was discovered on September 5, 1834 by John Herschel.
NGC 3613 is an elliptical galaxy in the constellation Ursa Major. It was discovered by the astronomer William Herschel on April 8, 1793. NGC 3613 is the center of a cluster of galaxies, and has an estimated globular cluster population of over 2,000.
NGC 3254 is a spiral galaxy in the constellation Leo Minor. It was discovered on March 13, 1785, by the astronomer William Herschel. It is a member of the NGC 3254 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.
