Messier 74 (also known as NGC 628 and Phantom Galaxy) is a large spiral galaxy in the equatorial constellation Pisces. [ a ] It is about 32 million light-years away from Earth. [ 6 ] The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy . [ 7 ]
The face-on spiral galaxy M74 (NGC 628) is the brightest galaxy within the group. Other members include the peculiar spiral galaxy NGC 660 and several smaller irregular galaxies . [ 1 ] [ 2 ] [ 3 ] The M74 Group is one of many galaxy groups that lie within the Virgo Supercluster .
For example, Messier 1 is a supernova remnant, known as the Crab Nebula, and the great spiral Andromeda Galaxy is M31. Further inclusions followed; the first addition came from Nicolas Camille Flammarion in 1921, who added Messier 104 after finding Messier's side note in his 1781 edition exemplar of the catalogue.

Charles Messier (French: [ʃaʁl me.sje]; 26 June 1730 – 12 April 1817) was a French astronomer. He published an astronomical catalogue consisting of 110 nebulae and star clusters , which came to be known as the Messier objects , referred to with the letter M and their number between 1 and 110.

The central supermassive black hole is calculated to have a mass of about 8.4 × 10 6 M ☉. [9] The interstellar medium of Messier 64 consists of two counter-rotating disks that are approximately equal in mass. [19] The inner disk contains the prominent dust lanes of the galaxy. The stellar population of the galaxy exhibits no measurable ...
