Galaxy in the constellation Fornax
NGC 1428 is apeculiar galaxy [ 4] morphology ; either anelliptical orlenticular galaxy [ 5] light-years away fromEarth .[ 6]
It was discovered by astronomerJulius Schmidt on January 19, 1865.[ 7] Fornax Cluster .[ 8]
40 knownglobular clusters have been observed surrounding NGC 1428[ 9] planetary nebulae .[ 10]
Physical characteristics [ edit ] NGC 1428 is host to anuclear star cluster with an estimated mass ranging from 1.4 × 107 [ 11] 7 M ☉ [ 12] nuclear stellar disk formed from multiple instances of gas acrecction and subsequent episodes ofstar formation . The presence of counter-rotating population of stars suggests the occurrence ofmergers that occurred in the opposite direction of the rotation of NGC 1428.[ 11]
The galaxy has asupermassive black hole with an estimated mass of 4.1 × 107 M ☉ [ 13]
