NGC 151 is a mid-sized barred spiral galaxy[3] located in the constellation Cetus.
The galaxy was discovered by English astronomer William Herschel on November 28, 1785. In 1886, Lewis Swift observed the same galaxy and catalogued it as NGC 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.
Two supernovae have been observed in NGC 151. On 22 July 2011, PTF11iqb (type IIn, mag. 17.1)[5] was discovered, and on 24 June 2023, SN 2023lnh (type Ia, mag. 18) was discovered.[6]
