| Description | A lovely Intermediate spiral galaxy... meaning intermediate between a classic spiral and barred. The spiral structure is prominent in the brighter, more central section of the galaxy. However the brightest part of the center is beginning to elongate into a bar, and the outer arms of the galaxy are taking on a classic reverse "S" shape characteristic of more mature, barred galaxies. |
