NGC 908 is an unbarred spiral galaxy in the constellation Cetus. It was discovered on 20 September 1786 by William Herschel.{{cite web | url = https://cseligman.com/text/atlas/ngc9.htm#908 | title = New General Catalogue Objects: NGC{{nbsp}}908 | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 29 August 2024 }} 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.{{cite journal|last1=Dmitry Makarov and Igor Karachentsev|title=Galaxy groups and clouds in the local (z∼ 0.01) Universe|journal=MNRAS|date=2011|volume=412|issue=4|pages=2498–2520|doi=10.1111/j.1365-2966.2010.18071.x|doi-access=free |arxiv=1011.6277|bibcode=2011MNRAS.412.2498M|s2cid=119194025}}
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.{{cite web|url=https://www.eso.org/public/images/eso0627a/|title=The Starburst Galaxy NGC 908|website=ESO|date=26 July 2006|access-date=9 November 2020}}
