A grand design spiral galaxy is a 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 significant portion of the galaxy's circumference.
This list is incomplete; you can help by adding missing items. ( August 2008 ) A spiral galaxy is a type of galaxy characterized by a central bulge of old Population II stars surrounded by a rotating disc of younger Population I stars.
The smaller galaxy NGC 5195 is tidally interacting with the larger Whirlpool Galaxy, creating its grand design spiral galaxy architecture. [citation needed] M81; M82; NGC 3077; These three galaxies interact with each other and draw out tidal tails, which are dense enough to form star clusters. The bridge of gas between these galaxies is known ...
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]
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).
Fourth known spiral DRAGN; first located in a grand design spiral galaxy. It was discovered by cross-matching spiral galaxies identified by galaxy zoo volunteers with the Unified Radio Catalog. It was the first systematic search for spiral DRAGNs. [1] [15] [10] [16] J0836+0532 2015 Two clear spiral arms [17] J1159+5820 2012/2015
This type of galaxy is known as "grand design". [1] NGC 7541 is actually observed to have a higher-than-usual star formation rate, adding weight to the theory that spiral bars act as stellar nurseries, corralling and funneling inwards the material and fuel needed to create and nurture new baby stars .
