NGC 6000
An oval-shaped spiral galaxy, of which only the centre and lower half is in frame. Its centre is mainly golden in colour with a white glowing core, while its thick spiral arms are mostly blue, particularly at the outskirts; the colours merge in between. Dark lanes of dust swirl through the centre, blocking some of its light. Stars and distant galaxies can be seen around the edges on a black background.

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]

Supernovae

Two supernovae have been observed in NGC 6000:

  • SN 2007ch (Type II, mag. 17.2) was discovered by L. A. G. "Berto" Monard on 11 May 2007.[6][7]
  • SN 2010as (Type Ib/Ic, mag. 15.5) was discovered by The CHilean Automatic Supernova sEarch (CHASE) on 19 March 2010.[8][9]
