NGC 3278 is a spiral galaxy in the constellation of Antlia. Its velocity with respect to the cosmic microwave background is 3,268±43 km/s, which corresponds to a Hubble distance of 157.2 ± 11.3 Mly (48.20 ± 3.47 Mpc).[1] However, four non-redshift measurements give a closer mean distance of 129.40 ± 1.29 Mly (39.675 ± 0.394 Mpc).[2] It was discovered by British astronomer John Herschel on 2 March 1835.[4]
NGC 3278 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.[5][6]
LDC 725 group
NGC 3278 is a member of a group of galaxies known as LDC 725. This group contains 28 galaxies, including NGC 3244, NGC 3250 (fr), NGC 3256, NGC 3261, NGC 3262 (fr), NGC 3263 (fr), and NGC 3283 (fr), among others.[3][7]
Supernova
One supernova has been observed in NGC 3278:
- SN 2009bb (Type Ic, mag. 17.0) was discovered by The CHilean Automatic Supernova sEarch (CHASE) on 21 March 2009.[8][9]
