NGC 908 is an unbarred spiral galaxy in the constellation Cetus. It was discovered on 20 September 1786 by William Herschel.^[3] This galaxy is 56 million light years away from Earth. It is the main galaxy in the NGC 908 group, which also includes NGC 899, NGC 907, and IC 223.^[4]

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.^[5]

Two supernovae have been observed in NGC 908: SN 1994ai (type Ic, mag. 17)^[6] and SN 2006ce (type Ia, mag. 12.4).^[7]^[8] Also, one luminous blue variable has been observed in this galaxy: AT 2021ablz (type LBV, mag. 20.6).^[9]
