NGC 2927 is a largebarred spiral galaxy in theconstellation ofLeo. Its velocity with respect to thecosmic microwave background is 7830 ± 20 km/s, which corresponds to aHubble distance of 115.49 ± 8.09Mpc (~377 millionlight-years).[1] In addition, threenon-redshift measurements give a distance of 120.667 ± 0.882 (~394 million light-years).[2] The galaxy was discovered by German astronomerHeinrich d'Arrest on 21 February 1863.[3]
TheSIMBAD database lists NGC 2927 as aradio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[4]
Onesupernova has been observed in NGC 2927: SN 2023uvg (type Ic, mag. 18.7389) was discovered by theAutomatic Learning for the Rapid Classification of Events (ALeRCE) on 13 October 2023.[5]
