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 oldest grand design spiral galaxy on file is BX442. At eleven billion years old, it is more than two billion years older than any previous discovery. Researchers believe the galaxy's shape is caused by the gravitational influence of a companion dwarf galaxy. Computer models based on that assumption indicate that BX442's spiral structure ...
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]
This is a list of NGC objects 4001–5000 from the New General Catalogue (NGC). The astronomical catalogue is composed mainly of star clusters , nebulae , and galaxies . Other objects in the catalogue can be found in the other subpages of the list of NGC objects .
