NGC 162 is a star in the Andromeda constellation. It was discovered by Heinrich d'Arrest in 1862. A few galaxies (PGC 2148 and PGC 212552) have been mis-identified as NGC 162. [3]
NGC 5829 is a spiral galaxy located in the constellation Boötes. It is 281 million light-years away from Earth and was discovered by astronomer, Edouard Stephan in May 1882.
NGC 321 is an elliptical galaxy located in the constellation Cetus. It was discovered on September 27, 1864, by the astronomer Albert Marth. Measurements of its redshift put it at a distance of about 217.4 ± 15.4 megalight-years (66.67 ± 4.73 Mpc), assuming a Hubble constant of H0 = 67.8 km/sec/Mpc.
NGC 46, occasionally referred to as PGC 5067596, is a star located approximately 1,420 light-years from the Solar System in the constellation Pisces. It was first discovered on October 22, 1852, by Irish astronomer Edward Joshua Cooper, who incorrectly identified it as a nebula.
NGC 65 is a lenticular galaxy in the constellation Cetus. Its apparent magnitude is 13.4. It was first discovered in 1886, and is also known as PGC 1229.
UGC 9796 is a lenticular and polar-ring galaxy in the constellation Boötes, and about 250 million light years distant from Earth. It is an object of great scientific interest as there have been very few polar ring galaxies discovered. UGC 9796 is a very gas-rich environment hosting as much 5×109 solar masses of neutral hydrogen. DSS and SDSS images show that it is very similar to polar ring galaxy NGC 660, the best-known of all the polar ring galaxies.
NGC 67 is an elliptical galaxy located in the constellation Andromeda that was discovered on October 7, 1855, by R. J. Mitchell, who described it as "extremely faint, very small, round". The galaxy belongs to the NGC 68 group, which also contains the galaxies NGC 68, NGC 69, NGC 70, NGC 71, NGC 72, and possibly NGC 74.
NGC 91 is a star with an apparent magnitude of 14.4 in the constellation of Andromeda. The star is southwest of the galaxy NGC 90. Discovered in 1866 by Herman Schultz, there have been many arguments if this star exists or not. However, people have observed the star, and have confirmed that NGC 91 exists.
NGC 131 is a spiral galaxy that was discovered on September 25, 1834, by John Herschel. This galaxy belongs in the NGC 134 group of galaxies: NGC 115, NGC 148, NGC 150, PGC 2000, IC 1555, and PGC 2044.
NGC 331 is a barred spiral galaxy in the constellation Cetus. It was discovered in 1886 by Francis Leavenworth. It was described by Dreyer as "extremely faint, very small, round, a little brighter middle, 12th magnitude star 3 arcmin northeast." There are two candidates as to which object is NGC 331: PGC 2759 or PGC 3406, with the former being a much more likely candidate than the latter.
NGC 336 is a spiral galaxy in the constellation Cetus. It was discovered on October 31, 1885 by Francis Leavenworth. It was described by Dreyer as "very faint, small, round, suddenly brighter middle." It is also known as PGC 3470. Despite this, sometimes it is mistakenly identified as PGC 3526.
NGC 390 is a star located in the constellation Pisces. It was discovered on November 19, 1884 by Guillaume Bigourdan. It was described by Dreyer as very faint, very small, stellar." However, this position precesses to a position where there is nothing apart from a few scattered stars. Bigourdan's original measurements point exactly to a star, which is the most likely candidate for NGC 390; however, as a result of this confusion, a galaxy nearby has sometimes been mistaken as NGC 390.
NGC 6670 is a pair of interacting galaxies within the Draco constellation, which lie around 401 million light-years from Earth. Its shape resembles a leaping dolphin. NGC 6670 was discovered by Lewis A. Swift on July 31, 1886. NGC 6670 is a combination of two colliding disc galaxies which are known as NGC 6670E and NGC 6670W. The galaxy is 100 billion times brighter than the Sun. The galaxies have already collided once before and they are now moving towards each other again nearing a second collision. Its apparent magnitude is 14.3, its size is 1.0 arc minutes.
N11 is the brightest emission nebula in the north-west part of the Large Magellanic Cloud in the Dorado constellation. The N11 complex is the second largest H II region of that galaxy, the largest being the Tarantula Nebula. It covers an area approximately 6 arc minutes across. It has an elliptical shape and consists of a large bubble, generally clear interstellar area, surrounded by nine large nebulae. It was named by Karl Henize in 1956.
NGC 510 is a double star in the constellation of Pisces. The stars are separated 8", and located 7' ESE of NGC 499 and 9' WNW of NGC 515.
NGC 2936, also known as the Penguin Galaxy or the Porpoise Galaxy, is an interacting spiral galaxy located at a distance of 326 million light years, in the constellation Hydra. NGC 2936 is interacting with elliptical galaxy NGC 2937, located just beneath it. They were both discovered by Albert Marth on Mar 3, 1864. To some astronomers, the galaxy looks like a penguin or a porpoise. NGC 2936, NGC 2937, and PGC 1237172 are included in the Atlas of Peculiar Galaxies as Arp 142 in the category "Galaxy triplet".
NGC 5529 is an edge-on intermediate spiral galaxy in the constellation Boötes. It is located approximately 144 million light-years away and was discovered by William Herschel on May 1, 1785.
NGC 2460 is an unbarred spiral galaxy in the constellation Camelopardalis. It was discovered by German astronomer Wilhelm Tempel on August 11, 1882.
NGC 811 is an object in the New General Catalogue. It is an elliptical galaxy located in the constellation Cetus about 700 million light-years from the Milky Way. It was discovered by the American astronomer Francis Leavenworth in 1886. However, it is usually misidentified as a different object, the spiral galaxy PGC 7905.
