Dark sky image with some objects around Pinwheel Galaxy (M 101). The quarter in the lower right shows the tail of Ursa Major with the stars Mizar, Alcor and Alkaid.. The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on, unbarred, and counterclockwise spiral galaxy located 21 million light-years (6.4 megaparsecs) [5] from Earth in the constellation Ursa Major.
Messier 83 or M83, also known as the Southern Pinwheel Galaxy and NGC 5236, is a barred spiral galaxy [7] approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas-Louis de Lacaille discovered M83 on 17 February 1752 at the Cape of Good Hope. [8]
Coma Pinwheel Galaxy, Virgo Cluster Pinwheel, M99, NGC 4254, PGC 39578, UGC 7345 [9] 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 .

SN 2023ixf is a type II-L [7] [8] (core collapse) supernova located in the Pinwheel Galaxy. It was first observed on 19 May 2023 by KÅichi Itagaki and immediately classified as a type II supernova. [2] Initial magnitude at discovery was 14.9. [2]
NGC 300 (also known as Caldwell 70 or the Sculptor Pinwheel Galaxy [4]) is a spiral galaxy in the constellation Sculptor. It was discovered on 5 August 1826 by Scottish astronomer James Dunlop. [5] It is one of the closest galaxies to the Local Group, and it most likely lies between the latter and the Sculptor Group.
Messier 101 (also known as the Pinwheel Galaxy or NGC 5457) is a face-on spiral galaxy in the constellation Ursa Major. In a letter written in 1783 to J. Bernoulli, Pierre Méchain (who had shared information about his discoveries with Messier) claimed that M102 was actually an accidental duplication of M101 in the catalog.
The M101 Group is a loose group of galaxies located in the constellation Ursa Major.The group is named after the brightest galaxy in the group, the Pinwheel Galaxy (M101). ). Most of the other members of the group are companions of the Pinwheel G
It was located in Messier 101, the Pinwheel Galaxy, 21 million light years from Earth. [3] It was observed by the PTF survey very near the beginning of its supernova event, when it was approximately 1 million times too dim to be visible to the naked eye. It is the youngest type Ia ever discovered. [5]
