| Notes | NGC 4725, aka the One Armed Galaxy, is referred to as a ringed barred spiral type. Unlike most spiral galaxies that have more than one arm, NGC 4715 has but one. It neatly wraps around the barred central portion in a beautiful ring shape, containing a host of bluish star-birthing HII areas as seen in the above image. This galaxy is located about 41 million light years from Earth and belongs to the Coma II subgroup of the much larger Coma-Sculptor association. A small but detailed oblique spiral galaxy, NGC 4712 can be seen in the lower part of the frame near the center. Many more faint, distant galaxies can also be spotted in the higher resolution rendition of this image. |
