NGC 6000
Galaxy in the constellation Scorpius
From Wikipedia, the free encyclopedia
NGC 6000 is a barred spiral galaxy located in the constellation Scorpius. Its velocity with respect to the cosmic microwave background is 2,328±9 km/s, which corresponds to a Hubble distance of 112.0 ± 7.9 Mly (34.33 ± 2.41 Mpc).[1] However, 5 non-redshift measurements give a closer mean distance of 88.84 ± 7.70 Mly (27.240 ± 2.362 Mpc).[3] It was discovered by British astronomer John Herschel on 8 May 1834.[4] It is designated as SB(s)bc in the galaxy morphological classification scheme, and is the brightest of all the galaxies in the constellation Scorpius.

NGC 6000 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.[5]
NGC 6000 has a glowing yellow centre with glittering blue outskirts.[6]
