A Spitzer Space Telescope image of Messier 81, a grand design spiral. A grand design spiral galaxy is a type of spiral galaxy with prominent and well-defined spiral arms, as opposed to multi-arm and flocculent spirals which have subtler structural features. The spiral arms of a grand design galaxy extend clearly around the galaxy, covering a ...
NGC 1232 is a face-on spiral galaxy. It can be technically considered a grand-design galaxy and is considered a prototype for multi-arm spiral galaxies. [7] Its galactic bulge is small. While NGC 1232 is classified as an intermediate spiral galaxy, the bulge shows hints of a galactic bar. [7]
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]
NGC 6872 is a barred spiral galaxy with a grand design spiral nucleus, and distinct well-formed outer barred-spiral architecture, caused by tidal interaction with satellite galaxy IC 4970. [citation needed] Tadpole Galaxy
A spiral galaxy maintains its spiral arms due to density wave theory. Spiral galaxies. Below is a list of notable spiral galaxies with their own articles.
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).
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]
NGC 4088 is a grand design spiral galaxy. [5] This means that the spiral arms in the galaxy's disk are sharply defined. In visible light, one of the spiral arms appears to have a disconnected segment. Halton Arp included this galaxy in the Atlas of Peculiar Galaxies as one of several examples where this phenomenon occurs. [6]
