This galaxy has very tight spiral "structure." However, no one feature extends long enough to be a spiral arm. This galaxy sports a curious ring of dust (dark circle) that surrounds the nucleus. It is estimated that this galaxy is around 41 million light years away. Note the very subtle difference in color between the inner yellowish region is outer bluish arms. This galaxy is not unlike NGC 488 and NGC 2841. This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014.
