A field galaxy is a galaxy that does not belong to a larger galaxy group or cluster and hence is gravitationally alone. Roughly 80% of all galaxies located within 5 Mpc (16 Mly) of the Milky Way are in groups or clusters of galaxies. [1] Most low-surface-brightness galaxies are field galaxies. [2]
This field galaxy [12] is located about 30 [3] million light-years away from the Milky Way, and is a member of the Virgo Supercluster. [4] The morphological classification of this galaxy is SBbc, [6] indicating a barred spiral (SB) with moderate to tightly-wound spiral arms (bc).
The morphological classification of NGC 3432 is SB(s)m, [4] which indicates this is a barred Magellanic spiral galaxy (SB) with no inner ring structure (s) and an irregular appearance (m). The galaxy is inclined at an angle of 85° ± 2° to the plane of the sky [ 2 ] with its major axis along a positional angle of 38°, which means it is being ...
NGC 3049 is a barred spiral galaxy located in the constellation Leo. Its velocity relative to the cosmic microwave background is 1793 ± 24 km/s, which corresponds to a Hubble distance of 26.4 ± 1.9 Mpc (∼86.1 million ly). [2] NGC 3049 was discovered by French astronomer Édouard Stephan in 1882. [3]
NGC 2608 (also known as Arp 12) is a barred spiral galaxy located 93 million light-years away in the constellation Cancer (the Crab). It is 62,000 light-years across, and about 60% of the width of the Milky Way.
NGC 5936 is a barred spiral galaxy in the constellation of Serpens. Its velocity with respect to the cosmic microwave background is 4131 ± 11 km/s, which corresponds to a Hubble distance of 60.93 ± 4.27 Mpc (∼199 million light-years). [1] It was discovered by German-British astronomer William Herschel on 12 April 1784. [2]

NGC 7424 is a barred spiral galaxy located 37.5 million light-years away in the southern constellation Grus (the Crane). Its size (about 100,000 light-years) makes it similar to our own galaxy, the Milky Way. [3] It is called a "grand design" galaxy because of its well defined spiral arms.
