NGC 1399 is a large elliptical galaxy in the Southern constellation Fornax, the central galaxy in the Fornax cluster. [2]

Characteristics

It is a type-cD galaxy, with a bright center and a vast, diffuse envelope surrounding it.[3] It is also rich in globular clusters, with a population of them that has been estimated to be between 5,700[4] and 6,500.[5]

A supermassive black hole with a mass of 500 million solar masses may be present in the center of this galaxy.[6]
