NGC 151 is a mid-sizedbarred spiral galaxy[3] located in the constellationCetus.
The galaxy was discovered by English astronomerWilliam Herschel on November 28, 1785. In 1886, Lewis Swift observed the same galaxy and catalogued it asNGC 153, only for it later to be identified as NGC 151.[4]
The galaxy, viewed from almost face on, has several bright, blue, dusty spiral arms filled with active star formation. One noticeable feature of the galaxy is a large gap between the spiral arms.
Twosupernovae have been observed in NGC 151. On 22 July 2011,PTF11iqb (type IIn, mag. 17.1)[5] was discovered by thePalomar Transient Factory, and on 24 June 2023, SN 2023lnh (type Ia, mag. 18) was discovered byATLAS.[6]
