Messier 63 or M63, also known as NGC 5055 or the seldom-used Sunflower Galaxy, is a spiral galaxy in the northern constellation of Canes Venatici with approximately 400 billion stars. M63 was first discovered by the French astronomer Pierre Méchain, then later verified by his colleague Charles Messier on June 14, 1779. The galaxy became listed as object 63 in the Messier Catalogue. In the mid-19th century, Anglo-Irish astronomer Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.
NGC 7793 is a flocculent spiral galaxy in the southern constellation of Sculptor. It was discovered in 1826 by Scottish astronomer James Dunlop. The galaxy is located at a distance of 12.2 million light years and is receding with a heliocentric radial velocity of 227 km/s. NGC 7793 is one of the five brightest galaxies within the Sculptor Group.
NGC 514 is a low-luminosity, intermediate spiral galaxy in the equatorial constellation of Pisces, located at a distance of approximately 83 million light-years from the Milky Way. It was discovered on 16 October 1784 by astronomer William Herschel. The general form of the galaxy is specified by its morphological classification of SAB(rs)c, which indicates it has a weak bar system at the core (SAB), an incomplete ring formation around the bar (rs), and somewhat loosely-wound spiral arms (c). This galaxy has an H II nucleus with an extended region that displays weak emission lines in the optical range, but not in the near infrared. The suspected supermassive black hole at the core has an estimated mass of 3.2×106 M☉.
NGC 10 is a spiral galaxy located in the southern constellation of Sculptor. It was discovered by John Herschel on 25 September 1834. The galaxy is located at a distance of 346 Mly from the Sun. Its morphological classification in the De Vaucouleurs system is SAB(rs)bc, where the 'SAB' denotes a weak-barred spiral, '(rs)' indicates a slight ring-like structure, and 'bc' means the spiral arms are moderately to loosely wound. Paturel et al. (2003) assigned this galaxy a classification of SBbc, indicating a barred spiral galaxy.
NGC 2397 is a flocculent spiral galaxy located in the southern Volans constellation, about one degree to the SSE of Delta Volantis. English astronomer John Herschel discovered the galaxy on February 21, 1835. It is located at a distance of approximately 69 million light years from the Sun, and is a member of the small NGC 2442 group that includes NGC 2434.
NGC 3021 is a spiral galaxy in the northern constellation of Leo Minor. It is about 93 million light-years away from Earth, and is receding with a heliocentric radial velocity of 1,537±4 km/s. This galaxy was discovered December 7, 1785 by Anglo-German astronomer William Herschel. The morphological classification of NGC 3021 is SA(rs)bc, which indicates a spiral galaxy with no central bar (SA), an incomplete inner ring structure (rs), and moderate to loosely wound spiral arms (bc).
NGC 214 is a spiral galaxy in the northern constellation of Andromeda, located at a distance of 194 megalight-years from the Milky Way. It was discovered on September 10, 1784 by William Herschel. The shape of this galaxy is given by its morphological classification of SABbc, which indicates a weak bar-like structure (SAB) at the core and moderate to loosely-wound spiral arms (bc).
NGC 3294 is a spiral galaxy in the constellation Leo Minor. It was discovered by William Herschel on Mar 17, 1787. It 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. The galaxy is located at a distance of 98 million light years and is receding with a heliocentric radial velocity of 1,586 km/s. The morphological class of NGC 3294 is SA(rs)bc, which means this is a spiral galaxy with no central bar (SA), an incomplete inner ring structure (rs), and moderately wound spiral arms (bc).
NGC 820 is a spiral galaxy located in the constellation Aries about 210 million light-years from the Milky Way. It was discovered by British astronomer John Herschel in 1828.
NGC 840 is a barred spiral galaxy in the constellation Cetus south of the ecliptic. It is estimated to be about 300 million light-years from the Milky Way and has a diameter of approximately 175,000 ly.
NGC 940 is a lenticular galaxy in the constellation Triangulum. It is estimated to be 222 million light-years from the Milky Way and has a diameter of approximately 80,000 ly. NGC 940 was discovered by Heinrich d'Arrest.
NGC 980 is a lenticular galaxy located in the constellation Andromeda about 256 million light years from the Milky Way. It was discovered by the German - British astronomer William Herschel in 1786.
NGC 825 is an unbarred spiral galaxy in the constellation Cetus, estimated to be 154 million light-years away. The object was discovered by the astronomer Albert Marth on November 18, 1863.
NGC 912 is a compact lenticular galaxy located in the constellation Andromeda about 197 million light years from the Milky Way. It was discovered by French astronomer Édouard Stephan in 1878.
NGC 991 is an intermediate spiral galaxy the constellation Cetus. This galaxy was discovered by astronomer William Herschel in 1785.
NGC 938 is an elliptical galaxy located in the constellation Aries, approximately 184 million light years from the Milky Way. It was discovered by the Prussian astronomer Heinrich d'Arrest in 1863.
