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 and later was identified to be 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.

On July 22, 2011, a supernova was discovered within NGC 151 and designated PTF11iqb.[5]
