This is an example of "multiple arm" spirals due to two apparent sets of arms, one close in to the center, and the outer, looser set. The diameter is around 90,000 light |
| 64 | 194.13 | 21.69999 | Black Eye Galaxy | 10.0'x5.0' | 8.5 | Spiral Galaxy | Coma Berenices | M64 is called "The Black Eye" galaxy due to its dark dust lane sweeping around the nucleus. M64 is believed to be about 50,000 light years in diameter, or half of our own Milky Way. |

It is one of the faster moving objects, heading away from us at nearly 1300 miles/second. Messier discovered M88 in 1781, and described it merely as a "nebula without a star". | |
