NGC 523, also known as Arp 158, from the ARP catalog is a spiral galaxy located in the constellation Andromeda. [1] It was discovered separately by William Herschel on 13 September 1784, and by Heinrich d'Arrest on 13 August 1862. d'Arrest's discovery was listed as NGC 523, while Herschel's was listed as NGC 537; the two are one and the same. [4] John Dreyer noted in the New General Catalogue that NGC 523 is a double nebula. [1]

<span class="mw-page-title-main">NGC 68</span> Galaxy in the constellation Andromeda

NGC 68 is a lenticular galaxy, and the central member of the NGC 68 group, in the constellation Andromeda. The galaxy was discovered on September 11, 1784, by William Herschel, who observed the NGC 68 group as a single object and described it as "extremely faint, large, 3 or 4 stars plus nebulosity". As such, his reported location is between NGC 68, NGC 70, and NGC 71. By the time Dreyer looked at the galaxies to add to the NGC catalog, however, he was able to tell that the single galaxy observed by Herschel was in fact 3 adjacent galaxies, and cataloged them as NGC 68, NGC 70, and NGC 71.

<span class="mw-page-title-main">NGC 71</span> Galaxy in the constellation Andromeda

NGC 71 is an elliptical galaxy located in the constellation Andromeda. It is in the NGC 68 group. The galaxy was discovered by R. J. Mitchell in 1855, and observed in 1865 by Heinrich d'Arrest, who described it as "extremely faint, very small, round". The galaxy is about 110,000-130,000 light years across, making it just slightly larger than the Milky Way. The galaxy is the second largest in the NGC 68 group, after spiral galaxy NGC 70.

NGC 7003 is a spiral galaxy around 220 million light-years from Earth in the constellation Delphinus. NGC 7003 has an estimated diameter of 80,800 light-years. The galaxy was discovered by German astronomer Heinrich Louis d'Arrest on August 26, 1864. There also has been at least one supernova observed in NGC 7003.

NGC 507, also known as Arp 229, CGCG 502-67, MCG 5-4-44, PGC 5098, UGC 938, and V V 207, is a lenticular galaxy in the constellation Pisces. It was described as being "very faint", "pretty large", "round", "brighter in the middle", and "south of NGC 508" by John Dreyer in the New General Catalogue. The two galaxies are a part of the Atlas of Peculiar Galaxies, where NGC 507 is described as "Circular or near circular rings of small density difference."
