Messier 64 - M64 - Black Eye Galaxy (Spiral Galaxy)


Messier 64 - M64 - Black Eye Galaxy (Spiral Galaxy)


M64 is a beautiful spiral galaxy known as the Black Eye Galaxy due to a spectacular dark band of absorbing dust in front of the nucleus, resulting in a smudged appearance. With an apparent magnitude of +8.8, it can be glimpsed with good binoculars on dark nights, appearing as a faint slightly irregular patch of light.

The Black Eye Galaxy is located in the constellation of Coma Berenices and was discovered by English astronomer Edward Pigott on March 23, 1779. Twelve days later Johann Elert Bode independently found it and Charles Messier adding it to his catalogue on March 1, 1780. The dark dust feature was discovered by William Herschel in 1785, comparing it to a black eye.

It's located 5 degrees northwest of Diadem (α Com - mag. +4.3) on an imaginary line connecting stars, 35 Com (mag. +4.9) and 40 Com (mag. +5.5), with M64 positioned one degree northeast of 35 Com.Arcturus, the brightest star in the northern section of the sky and fourth brightest overall is located 19 degrees east and a little south of M64.

The galaxy is 24 Million light-years distant and has an apparent size of 10.0 x 5.4 arc minutes, which corresponds to an actual linear diameter of 70,000 light-years. It's estimated to contain 100 billion stars and is best seen from northern latitudes during the months of March, April and May.
