NGC 6708
Galaxy in the constellation Telescopium
From Wikipedia, the free encyclopedia
NGC 6708 is a spiral galaxy in the constellation of Telescopium. Its velocity with respect to the cosmic microwave background is 2,520±14 km/s, which corresponds to a Hubble distance of 121.2 ± 8.5 Mly (37.17 ± 2.62 Mpc).[1] Additionally, one non-redshift measurement gives a similar distance of 116 Mly (35.7 Mpc).[2] It was discovered by British astronomer John Herschel on 9 June 1836.[3][4]

Supernovae
Three supernovae have been observed in NGC 6708:
- SN 2004do (Type Ia, mag. 16.3) was discovered by South African amateur astronomer Berto Monard on 4 August 2004.[7][8]
- SN 2011ce (Type Iax, mag. 15.8) was discovered by The CHilean Automatic Supernova sEarch (CHASE) on 19 April 2011.[9][10] It was initially classified as Type Ia-pec, but later analysis concluded that it was Type Iax.[11]
- SN 2025tam (Type II, mag. 16.044) was discovered by ATLAS on 2 August 2025.[12]
