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.
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]
NGC 3631 is a spiral galaxy located in the constellation Ursa Major. It is located at a distance of about 35 million light years from Earth, which, given its apparent dimensions, means that NGC 3631 is about 60,000 light years across. It was discovered by William Herschel on April 14, 1789. [2] It is a grand design spiral galaxy seen face on.
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]
Messier 99 or M99, also known as NGC 4254 or St. Catherine's Wheel, is a grand design spiral galaxy in the northern constellation Coma Berenices approximately 15,000,000 parsecs (49,000,000 light-years) from the Milky Way. [5] It was discovered by Pierre Méchain on 17 March 1781.
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]
NGC 6118 is a grand design spiral galaxy located 83 million light-years away in the constellation Serpens (the Snake). It was discovered on 14 April 1785 by German-British astronomer William Herschel. [3] NGC 6118 measures roughly 110,000 light-years across; about the same as our own galaxy, the Milky Way.
NGC 1300 is a barred spiral galaxy located about 65 million light-years away in the constellation Eridanus.The galaxy is about 110,000 light-years across. It is a member of the Eridanus Cluster, a cluster of 200 galaxies, [3] [4] [5] in a subgroup of 2-4 galaxies in the cluster known as the NGC 1300 Group.
