NGC 6106 is a spiral galaxy in the constellation of Hercules. Its velocity with respect to the cosmic microwave background is 1,527±6 km/s, which corresponds to a Hubble distance of 73.5 ± 5.2 Mly (22.52 ± 1.58 Mpc).[1] This is in good agreement with 29 non-redshift measurements which give an average distance of 72.64 ± 2.49 Mly (22.272 ± 0.764 Mpc).[2] It was discovered by German-British astronomer William Herschel on 13 April 1784.[3][4]

NGC 6106 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[5][6]
Luminous red nova and supernova
