The advent of radio astronomy and subsequent radio images of M51 unequivocally demonstrated that the Whirlpool and its companion galaxy are indeed interacting. Sometimes the designation M51 is used to refer to the pair of galaxies, in which case the individual galaxies may be referred to as M51a (NGC 5194) and M51b (NGC 5195).
NGC 5195 (also known as Messier 51b or M51b) is a dwarf galaxy that is interacting with the Whirlpool Galaxy (also known as M51a or NGC 5194). Both galaxies are located approximately 25 million light-years away in the constellation Canes Venatici. Together, the two galaxies are one of the most famous interacting galaxy pairs.
The M51 Group is located to the southeast of the M101 Group and the NGC 5866 Group. [6] The distances to these three groups (as determined from the distances to the individual member galaxies) are similar, which suggests that the M51 Group, the M101 Group, and the NGC 5866 Group are actually part of a large, loose, elongated structure.

The 15th anniversary, in 2005, was celebrated with a collection of images of M51 (the Whirlpool Galaxy), and also with a section of the Eagle nebula. [2] The 15th anniversary included a collection of other content including, in multiple languages, the video release, Hubble — 15 Years of Discovery.
This object consists of a larger spiral galaxy interacting with an elliptical galaxy. Galaxies in this category are almost always clearly interacting sources. The most famous of these objects is the Whirlpool Galaxy (M51; Arp 85), which is composed of a spiral galaxy NGC 5194 that is interacting with a smaller elliptical galaxy NGC 5195. The ...

SN 2005cs was a supernova in the spiral galaxy M51, [3] known as the Whirlpool Galaxy. It was a type II-P core-collapse supernova, discovered June 28, 2005 by Wolfgang Kloehr, a German amateur astronomer. [5] The event was positioned at an offset of 15″ west and 78″ south of the galactic nucleus of M51. [2]
