NGC 908 is an unbarred spiral galaxy in the constellation Cetus. It is 60 million light years away from Earth. NGC 908 has vigorous star formation and is a starburst galaxy. The galaxy has a three-arm spiral pattern; two of its arms have peculiar morphology. The galaxy has a bright central bulge. Clusters of young stars and star-forming knots can be seen in the arms. Starburst activity and the peculiar morphology of the galaxy indicate it had a close encounter with another galaxy, although none are visible now.[3] NGC 908 was discovered in 1786 by William Herschel. Two supernovae have been observed in NGC 908, SN 1994ai (Ic type, mag. 17) and SN 2006ce (Ia type, mag. 12.4).[4] It is the main galaxy in the NGC 908 group, which also includes NGC 899, NGC 907, and IC 223.[5]
