NGC 428 is a barred spiral galaxy in the constellation of Cetus (The Sea Monster), with its spiral structure distorted and warped, possibly the result of the collision of two galaxies.[3] There appears to be a substantial amount of star formation occurring within NGC 428 and it lacks well defined arms — a telltale sign of a galaxy merger.[3] In 2015 the Hubble Space Telescope made a close-up shot of the galaxy with its Advanced Camera for Surveys and its Wide Field and Planetary Camera 2.[1] The structure of NGC 428 has been compared to NGC 5645.[4]

Discoveries

NGC428 by Hubble Space Telescope

NGC 428 was discovered by William Herschel in December 1786.[3] A type Ia supernova designated SN2013ct was discovered May 11, 2013, within the galaxy by Stuart Parker of the Backyard Observatory Supernova Search (BOSS) project in Australia and New Zealand.[3][5]

Smoker et al. reported in 1996 on the NGC 428 field, with the HI tail and LSB dwarf 0110+008, assessing star formation properties based on molecule density distributions, and concluded that the tail formation most likely originated through tidal interactions between two galaxies.[6]
