Cetus lies far from the [[galactic plane]], so that many distant [[galaxy|galaxies]] are visible, unobscured by dust from the [[Milky Way]]. Of these, the brightest is [[Messier 77]] (NGC 1068), a 9th magnitude [[spiral galaxy]] near [[Delta Ceti]]. It appears face-on and has a clearly visible nucleus of magnitude 10. About 50 million light-years from Earth, M77 is also a [[Seyfert galaxy]] and thus a bright object in the [[radio spectrum]].{{sfn|Ridpath|Tirion|2001|pp=114-116}} Recently, the galactic cluster [[JKCS 041|JKCS&nbsp;041]] was confirmed to be the most distant [[cluster of galaxies]] yet discovered.<ref>{{cite news|title=Scientists identify new |url=http://www.metro.co.uk/news/756711-scientists-identify-new-galaxy|newspaper=Metro|date=23 October 2009}}</ref> The [[Pisces–Cetus Supercluster Complex]] is a galaxy filament that is one of the [[List of largest cosmic structures|largest known structures]] in the observable Universe; it contains the [[Virgo supercluster]] which contains the [[Local Group]] of Milky Way and other galaxies.<ref name="tully86">{{Cite journal |last=Tully |first=R.

The massive [[cD galaxy]] [[Holmberg 15A]] is also found in Cetus; as are the spiral galaxy [[NGC 1042]], the elliptical galaxy [[NGC 1052]] and the ultra-diffuse galaxy [[NGC 1052-DF2]].

[[IC 1613]] ([[Caldwell catalog|Caldwell]] 51) is an irregular [[dwarf galaxy]] near the star 26 Ceti and is a member of the Local Group.

[[NGC 246]] (Caldwell 56), also called the "Cetus Ring",<ref>{{Cite book |last=Levy |first=Daniel H. |title=Deep Sky Objects: The Best And Brightest from Four Decades of Comet Chasing |publisher=[[Prometheus Books]] |year=2011 |location=United States |pages=129 |language=en}}</ref> is a [[planetary nebula]] with a magnitude of 8.0 at 1600 light-years from Earth. Among some amateur astronomers, NGC 246 has garnered the nickname "Pac-Man Nebula" because of the arrangement of its central stars and the surrounding star field.{{sfn|Levy|2005|p=129}}

The [[Wolf–Lundmark–Melotte]] (WLM) is a barred irregular galaxy discovered in 1909 by [[Max Wolf]], located on the outer edges of the Local Group. The discovery of the nature of the galaxy was accredited to [[Knut Lundmark]] and [[Philibert Jacques Melotte]] in 1926.

UGC 1646, which is a spiral galaxy, also lies between the borders of the constellation. It is about 150 million light-years away from us. It can be seen near TYC 43-234-1 star.<ref>{{Cite web |title=UGC 1646 |url=https://simbad.cds.unistra.fr/simbad/sim-basic |access-date=2024-01-01 |website=simbad.cds.unistra.fr}}</ref><ref>{{Cite web |title=JWST Feed - Target Name: 2MASS-11595807+2807159 Title: JWST Routine Wavefront Sensing and Control for Cycle 2 Instrument: NIRCAM/IMAGE Filters: F356W Start Time: 12/21/2023 10:06:59 AM Obs Time: 85.894(s) Proposal ID: 4504 |url=https://jwstfeed.com/PostView/FeedPost?ci=1703170622_jw04504-o196_t040_nircam_clear-f356w-nrcalong_wfscmb-04 |access-date=2024-01-01 |website=jwstfeed.com |language=en}}</ref>
