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 ]
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.

One of the more significant galaxies in Canes Venatici is the Whirlpool Galaxy (M51, NGC 5194) and NGC 5195, a small barred spiral galaxy that is seen face-on. This was the first galaxy recognised as having a spiral structure, this structure being first observed by Lord Rosse in 1845. [12]
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 ...
