NGC 6324 is a spiral galaxy in the constellation of Ursa Minor. Its velocity with respect to the cosmic microwave background is 4,825±38 km/s, which corresponds to a Hubble distance of 232.1 ± 16.4 Mly (71.16 ± 5.04 Mpc).[1] It was discovered by German-British astronomer William Herschel on 12 December 1797.[2][3]
NGC 6324 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.[4][5]
Supernovae
[edit]Two supernovae have been observed in NGC 6324:
- SN 2002ej (Type II, mag. 17.5) was discovered by Tim Puckett and Brian Kerns on 9 August 2002.[6][7]
- SN 2026aur (Type Ib, mag. 19.2987) was discovered by the Zwicky Transient Facility on 9 January 2026.[8]
