NGC 4596 is a barred lenticular galaxy located about 55 million light-years away[2] in the constellation Virgo.[3] NGC 4596 was discovered by astronomer William Herschel on March 15, 1784.[4] NGC 4596 is a member of the Virgo Cluster[5] [6] and has an inclination of about 38°.[7]

Physical characteristics

NGC 4596 has a strong bar with bright ansae at the ends. Two diffuse spiral arms branch off from the ends of the bar and form an inner pseudoring that is well-defined. The spiral arms continue out and fade rapidly in the bright outer disk.[8]

Supermassive black hole

NGC 4596 has a supermassive black hole with an estimated mass of 78 million suns (M☉).[9] [10] [11]
