| DETAILS | NGC4826, also known as M64 or Blackeye galaxy is classed as a spiral with Seyfert 2 activity. It is unusual in as much as it has counter rotating gaseuos rings and a very heavy dust lane close to the centre. The rings are thought to be the result of a collision with a smaller galaxy that had a lot of gas. |
