It was discovered by astronomer Julius Schmidt on January 19, 1865.[7] It is a member of the Fornax Cluster.[8]
40 known globular clusters have been observed surrounding NGC 1428[9] along with 23 observed planetary nebulae.[10]
NGC 1428 is host to a nuclear star cluster with an estimated mass ranging from 1.4 × 107 [11] to 2.2 × 107 M☉.[12] It is thought that this nuclear star cluster which surrounded by a nuclear stellar disk formed from multiple instances of gas acrecction and subsequent episodes of star formation. The presence of counter-rotating population of stars suggests the occurrence of mergers that occurred in the opposite direction of the rotation of NGC 1428.[11]
The galaxy has a supermassive black hole with an estimated mass of 4.1 × 107 M☉.[13]
