NGC 6047 is an elliptical galaxy located about 430 million light-years away [2] in the constellation Hercules. [3] It was discovered by astronomer Lewis Swift on June 27, 1886. [4] NGC 6047 is a member of the Hercules Cluster. [5] [6] [7]
NGC 6047 has a peculiar morphology [5] [8] [9] which suggests it has undergone a recent merger. [6] [7] [10] It may be interacting with NGC 6045 which lies around ~320,000 ly (97 kpc) away. [8] NGC 6047 has two radio jets [6] [7] and is classified as a FR I radio galaxy. [9] The jets appear to have a Z-shaped structure. [5]
