NGC 1316 — Galaxy in Fornax

NGC 1316, also known as Fornax A, is a peculiar lenticular galaxy in Fornax about 62 million light-years away and the brightest member of the Fornax Cluster. It is one of the strongest radio sources in the southern sky, with a pair of huge radio lobes extending nearly a degree across and powered by an active supermassive black hole. The optical body shows complex shells, ripples, and dust lanes — clear evidence that NGC 1316 is the remnant of a recent major merger, probably between two gas-rich disk galaxies a few billion years ago. At magnitude 8.9 it is one of the brightest galaxies in the southern sky.

An easy target from southern locations. A 4-inch at moderate power shows a bright round glow with a prominent core; an 8-inch reveals an extended elliptical halo with hints of the chaotic substructure. A 12-inch under good skies begins to suggest the dust patches near the centre. The smaller, fainter NGC 1317 sits just six arcminutes north, an attractive companion in the same field. NGC 1316 lies at declination -37 degrees, a moderate-altitude object from southern Europe and the southern United States. Best observed October through February.

Discovered by James Dunlop on 2 September 1826 from Parramatta. Identified as a strong radio source by John Bolton and colleagues at the Dover Heights field station in Sydney in the late 1940s, it was one of the first radio sources cross-matched with an optical galaxy — establishing the link between active galactic nuclei and radio emission. Modern HST imaging has resolved its merger debris in fine detail.
