NGC 3073 is a dwarf lenticular galaxy in the constellation Ursa Major. [4] [5] [6] It is at a distance of about 65 million light-years (20 megaparsecs) from Earth. [3] NGC 3073 was discovered by astronomer William Herschel on April 1, 1790. The galaxy belongs to the NGC 3079 Group. [7]
The Black Eye Galaxy is a relatively isolated spiral galaxy 17 million light-years away in the mildly northern constellation of Coma Berenices. It was discovered by Edward Pigott in March 1779, and independently by Johann Elert Bode in April of the same year, as well as by Charles Messier the next year. A dark band of absorbing dust partially in front of its bright nucleus gave rise to its nicknames of the "Black Eye", "Evil Eye", or "Sleeping Beauty" galaxy. M64 is well known among amateur astronomers due to its form in small telescopes and visibility across inhabited latitudes.
NGC 6782 is a barred spiral galaxy located in the southern constellation of Pavo, at a distance of approximately 173 megalight-years from the Milky Way. It was discovered on July 12, 1834 by English astronomer John Herschel. John L. E. Dreyer described it as, "considerably faint, considerably small, round, a little brighter middle, 9th magnitude star to south". The morphological classification of NGC 6782 is (R1R′2)SB(r)a, indicating a barred spiral galaxy with a multiple ring system and tightly-wound spiral arms. It is seen nearly face-on, being inclined by an angle of 27.2°±0.2° to the line of sight from the Earth.
NGC 4605 is a dwarf barred spiral galaxy in the constellation Ursa Major, located at a distance of 18.1 ± 0.3 megalight-years from the Milky Way. Physically it is similar in size and in B-band absolute magnitude to the Large Magellanic Cloud. It is a member of the M81 Galaxy Group, along with Messier 81 and Messier 101.
NGC 23 is a spiral galaxy located in the northern constellation of Pegasus, around 173.5 megalight-years distant from the Milky Way. It was discovered by William Herschel on 10 September 1784. In the Webb Society Deep-Sky Observer's Handbook, the visual appearance of NGC 23 is described as follows:
Bright, extended ellipse; a bright nuclear structure is noticeably elongated; two weak spiral enhancements emerge from opposite sides of the nucleus, one curving towards a bright star attached on the south end. The galaxy is likely interacting with NGC 9.
NGC 3550 is a lenticular galaxy in the constellation Ursa Major. It was discovered on April 11, 1785, by William Herschel. It is one of the brightest galaxies of the Abell 1185 galaxy cluster.
NGC 3539 is a lenticular galaxy in the constellation Ursa Major. It was discovered in April 1831 by John Herschel. It is a member of the galaxy cluster Abell 1185.
NGC 1404 is an elliptical galaxy in the Southern constellation Eridanus. It was discovered on November 28, 1837, by the astronomer John Herschel. Based on the tip of the red-giant branch distance indicator, it lies at a distance of approximately 60 million light-years from the Milky Way. It is one of the brightest members of the Fornax Cluster.
NGC 2613 is a spiral galaxy in the southern constellation of Pyxis, next to the western constellation border with Puppis. It was discovered by the German-born astronomer William Herschel on November 20, 1784. With an apparent visual magnitude of 10.5, the galaxy is faintly visible using a telescope with a 100 mm (4 in) aperture. It appears spindle-shaped as it is almost edge-on to observers on Earth.
NGC 178 is a Magellanic spiral galaxy in the constellation of Cetus. The compiler of the New General Catalogue, John Louis Emil Dreyer noted that NGC 178 was "faint, small, much extended 0°, brighter middle". It was discovered on November 3, 1885 by Ormond Stone.
NGC 4041 is the New General Catalogue identifier for a spiral galaxy in the northern circumpolar constellation of Ursa Major. It is located an estimated 70 million light years from the Sun. The morphological classification of SA(rs)bc indicates this is a spiral galaxy the lacks a bar; the 'rs' means it has a weakly-formed ring structure, and the 'bc' indicates the spiral arms are moderately to loosely wound.
NGC 4293 is a lenticular galaxy in the northern constellation of Coma Berenices. It was discovered by English astronomer William Herschel on March 14, 1784, who described it as "large, extended, resolvable, 6 or 7′ long". This galaxy is positioned to the north-northwest of the star 11 Comae Berenices and is a member of the Virgo Cluster of galaxies. It is assumed to lie at the same distance as the Virgo Cluster itself: around 54 million light years away. The galaxy spans an apparent area of 5.3 × 3.1 arc minutes.
NGC 4138 is the New General Catalogue identifier for a lenticular galaxy in the northern constellation of Canes Venatici. Located around 52 million light years from Earth, it spans some 2.1 × 1.3 arc minutes and has an apparent visual magnitude of 11.3. The morphological classification of NGC 4138 is SA0+(r), indicating it lacks a bar formation and has tightly wound spiral arms with a ring-like structure around the nucleus. It has no nearby companion galaxies.
NGC 4203 is the New General Catalogue identifier for a lenticular galaxy in the northern constellation of Coma Berenices. It was discovered on March 20, 1787 by English astronomer William Herschel, and is situated 5.5° to the northwest of the 4th magnitude star Gamma Comae Berenices and can be viewed with a small telescope. The morphological classification of NGC 4203 is SAB0−, indicating that it has a lenticular form with tightly wound spiral arms and a weak bar structure at the nucleus.
NGC 2998 is a barred spiral galaxy located in the constellation Ursa Major. It is 195 million light-years away from the Earth. It is an intermediate spiral galaxy. Its stellar mass is about that of the Milky Way.
NGC 3319 is a barred spiral galaxy in the constellation Ursa Major. It was discovered by William Herschel on Feb 3, 1788. It is rich in gas and lacks a galactic bulge.
NGC 1400 is an elliptical galaxy in the constellation Eridanus. At a distance of 65 million light-years from Earth, it was discovered by John Herschel in 1786. It is a member of the NGC 1407 group, whose brightest member is NGC 1407. The NGC 1407 group is part of the Eridanus Cluster, a cluster of 200 galaxies.
NGC 701 is a spiral galaxy with a high star formation rate in the constellation Cetus. It is estimated to be 86 million light years from the Milky Way and has a diameter of approximately 65,000 light years. The object was discovered on January 10, 1785 by the German-British astronomer William Herschel.
NGC 535 is a lenticular galaxy in the constellation Cetus. It is estimated to be 222 million light years from the Milky Way and has a diameter of approximately 65,000 light years. The supernova SN 1988ad was observed near these coordinates. NGC 535 was discovered on October 31, 1864, by astronomer Heinrich Ludwig d'Arrest.
NGC 706 is a spiral galaxy located in the Pisces constellation about 230 million light years from the Milky Way. It was discovered by the German–British astronomer William Herschel in 1786.
NGC 5619 is an intermediate spiral galaxy in the constellation Virgo. The galaxy was found on April 10, 1828 by the British astronomer John Herschel. It is located about 390 million light-years away from the Sun.
