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]
Appearance
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]
Stars observed
Two supernovae have been observed in NGC 908:
- SN 1994ai (Type Ic, mag. 17) was discovered by Robert McNaught on 20 December 1994.[6][7]
- SN 2006ce (Type Ia, mag. 12.4) was discovered by Libert "Berto" Monard on 10 May 2006.[8][9]
Also, one luminous blue variable has been observed in this galaxy: AT 2021ablz (type LBV, mag. 20.6) was discovered by Pan-STARRS on 14 October 2021.[10]
