NGC 4939
NGC 4939 is a very pretty example of a spiral galaxy. The arms of this galaxy are unusually thin and long. There are many starforming regions dotting the spiral arms- but at a distance of 130 million light years away the majority of them are quite dim. If this galaxy was viewed face-on it would appear nearly circular- not unlike NGC 488. NGC is also considered an active galaxy because its nucleus varies in intensity on relatively short timescales and it has had two recorded supernovae events (back in 1968 and 1973).
