NGC6389 is a spiral galaxy in the constellation of Hercules. Its velocity with respect to the cosmic microwave background is 3,071±3 km/s, which corresponds to a Hubble distance of 147.7 ± 10.3 Mly (45.29 ± 3.17 Mpc).[1] However, five non-redshift measurements give a farther mean distance of 163.60 ± 27.49 Mly (50.160 ± 8.428 Mpc).[2] It was discovered by German-British astronomer William Herschel on 29 June 1799.[3][4]
NGC 6389 is an active galaxy nucleus candidate, 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]
Supernovae
[edit]Two supernovae have been observed in NGC 6389:
- SN1992ab (TypeII, mag. 17) was discovered by Jean Mueller on 1 June 1992.[6][7]
- SN2000M (Type II, mag. 16.5) was discovered by Marco Migliardi during the Col Druscie Remote Observatory Supernova Search (CROSS), on 27 February 2000.[8][9]
