NGC 1316 (also known as Fornax A) is a

MHz is the fourth-brightest radio source in the sky.[5]

Structure and formation

In the late

clusters of galaxies.[5] Using spectroscopy of its brightest globular clusters, the merger is estimated to have occurred ~3 billion years ago.[8]
NGC 1316 spans about 50 000 light-years.[9]

It has been proposed too that NGC 1316 may be a galaxy in evolution that eventually will become a

Sombrero-like system dominated by a large bulge.[10]
Accuracy of such destinations and build of current and future galaxies and galactic formations and research methods are well established.

Companions and environment

The Fornax galaxy cluster with NGC 1316 (large, near middle)

NGC 1316 is located within the

cluster of galaxies in the constellation Fornax. However, in contrast to Messier 87, which is a similar elliptical galaxy that is located in the center of the Virgo Cluster, NGC 1316 is located at the edge of the Fornax Cluster.[11]

NGC 1316 appears to be interacting with NGC 1317, a small spiral galaxy to the north. However, that small spiral galaxy does not appear to be sufficiently large enough to cause the distortions seen in the structure of this galaxy.[5]

NGC 1316 has hosted four supernovae (all type Ia): 1980N, 1981D, 2006dd and 2006mr.[3][12]

Distance estimates

At least two methods have been used to estimate the distance to NGC 1316: surface brightness fluctuation (SBF) in 2003[2] and planetary nebula luminosity function (PNLF) in 2006.[3] Being a lenticular galaxy, it is not suitable to apply the cepheid variable method[why?]. Using SBF, a distance estimate of 20.0 ± 1.6 Mpc[2] was computed. Using PNLF, 45 planetary nebula candidates were located and a distance estimate of 17.9 +0.8
−0.9 Mpc was computed.[3] Averaged together, these two distance measurements give a combined distance estimate of 62.0 ± 2.9 Mly (19.0 ± 0.9 Mpc).[a]
