NGC 171 is a barred spiral galaxy with an apparent magnitude of 12, located around 200 million light-years away in the constellation Cetus. The galaxy has two main medium-wound arms, with a few minor arms, and a fairly bright nucleus and bulge. It was discovered on 20 October 1784 by William Herschel. [3] It is also known as NGC 175. [3]
Messier 66 or M66, also known as NGC 3627, is an intermediate spiral galaxy in the southern, equatorial half of Leo. It was discovered by French astronomer Charles Messier on 1 March 1780, who described it as "very long and very faint". This galaxy is a member of a small group of galaxies that includes M65 and NGC 3628, known as the Leo Triplet or the M66 Group. M65 and M66 are a common object for amateur astronomic observation, being separated by only 20′.
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 1 is an intermediate spiral galaxy of the morphological type Sbc, located in the constellation of Pegasus. It was discovered on 30 September 1861 by Heinrich d'Arrest.
NGC 7332 is an edge-on peculiar lenticular galaxy located about 67 million light-years away in the constellation Pegasus. It possesses a -shaped bulge, associated with stellar bar. It was discovered on September 19, 1784 by the astronomer William Herschel.
NGC 3223 is a faint spiral galaxy in the constellation Antlia. It was discovered on February 2, 1835 by the English astronomer John Herschel. The galaxy lies at a distance of approximately 110 million light years away and is receding with a heliocentric radial velocity of 2,896 km/s. The morphological class of NGC 3223 is SA(s)b, indicating it is a spiral with no central bar (SA), no inner ring feature, and moderately tightly wound spiral arms. The galactic plane is inclined at an angle of 46° to the line of sight from the Earth, with the major axis along a position angle of 128°. It has at least two well-defined arms and is flocculent in appearance.
NGC 5970 is a large barred-spiral galaxy located about 90 million light years away in the constellation Serpens Caput. It appears to have two satellite or companion galaxies. It is a member of the Virgo Cluster of galaxies. It was discovered on March 15, 1784, by the astronomer William Herschel.
NGC 210 is a barred spiral galaxy located roughly 67 million light-years from the Solar System in the constellation Cetus. It was discovered on October 3, 1785 by William Herschel and later added to the New General Catalogue.
NGC 151 is a mid-sized barred spiral galaxy located in the constellation Cetus.
NGC 128 is a lenticular galaxy in the constellation Pisces. It is approximately 190 million light-years from the Sun and has a diameter of about 165,000 light-years.
NGC 6120 is a peculiar spiral galaxy located roughly 440 million light-years away from the Sun. It is located in the northern constellation of Corona Borealis, and is a member of the Abell 2199 galaxy cluster.
NGC 167 is a spiral galaxy located approximately 172 million light-years from the Solar System in the constellation Cetus. It was discovered in 1886 by Francis Preserved Leavenworth.
NGC 174 is a barred spiral or lenticular galaxy around 159 million light-years away in the constellation Sculptor. It was discovered on 27 September 1834 by astronomer John Herschel.
NGC 218, also known as UGC 480, is a spiral galaxy located approximately 500 million light-years from the Sun in the constellation Andromeda. It was discovered on October 17, 1876 by Édouard Stephan, and is interacting with the galaxy PGC 2726.
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 468 is a spiral galaxy in the constellation Pisces. Located approximately 209 million light-years from Earth, it was discovered by John Frederick William Herschel in 1827.
NGC 4488 is a lenticular galaxy located about 60 million light-years away in the constellation of Virgo. The galaxy was discovered by astronomer William Herschel on December 28, 1785. NGC 4488 is a member of the Virgo Cluster.
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 4580 is an unbarred spiral galaxy located about 70 million light-years away in the constellation Virgo. NGC 4580 is also classified as a LINER galaxy. It was discovered by astronomer William Herschel on February 2, 1786 and is a member of the Virgo Cluster.
NGC 4326 is a barred spiral galaxy with a ring located about 330 million light-years away in the constellation Virgo. It was discovered by astronomer William Herschel on April 13, 1784, who described it as "vF, S, R, bM, 1st of 3". It is a large galaxy, with a diameter of around 200,000 ly (61 kpc) making it nearly twice the size of the Milky Way. NGC 4326 is also classified as a LINER galaxy. Despite being listed in the Virgo Cluster catalog as VCC 623, it is not a member of the Virgo Cluster but instead a background galaxy.
NGC 4333 is a barred spiral galaxy with a ring structure located about 330 million light-years away in the constellation Virgo. It was discovered by astronomer William Herschel on April 13, 1784, who described it as "F, pS, R, bM, 2nd of 3". NGC 4333 is also classified as a LINER galaxy.
