Density wave theory is the preferred explanation for the well-defined structure of grand design spirals, [2] first suggested by Chia-Chiao Lin and Frank Shu in 1964. [3] The term "grand design" was not used in this work, but appeared in the 1966 continuation paper; [4] Lin [5] (along with Yuan and Shu [6]) is usually credited with coining of the term.
Messier 74 (also known as NGC 628 and Phantom Galaxy) is a large spiral galaxy in the equatorial constellation Pisces. [a] It is about 32 million light-years away from Earth. [6] The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy. [7]
M83 is a massive, grand design spiral galaxy. [10] Its morphological classification in the De Vaucouleurs system is SAB(s)c, [ 2 ] where the 'SAB' denotes a weak-barred spiral, '(s)' indicates a pure spiral structure with no ring, and 'c' means the spiral arms are loosely wound. [ 11 ]

The Whirlpool Galaxy, also known as Messier 51a (M51a) or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. [6] [7] [8] It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. [9]
BX442 (Q2343-BX442 [1]) is a grand design spiral galaxy of type Sc. [1] It has a companion dwarf galaxy.It is the most distant known grand design spiral galaxy in the universe, with a redshift of z=2.1765 ± 0.0001. [1]
NGC 1079 is an isolated, weakly barred, grand-design spiral galaxy with transitional ring-like structures [3] containing a number of prominent A type stars. [1] It is located in the Fornax constellation and is part of the Eridanus supercluster. [4] It was first observed and catalogued by the astronomer John Herschel in 1835. [5]
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away in the constellation Ursa Major.It has a D 25 isophotal diameter of 29.44 kiloparsecs (96,000 light-years).
