NGC 5128
Description: NGC 5128
Date Taken: April 2004
Centuarus A. NGC 5128

Distance: 15million ly
RA:13h 25m 30.0s Dec:-43deg01'00" (Epoch 2000)
This galaxy is situated in the M83 group of galaxies. It is one of the most interesting and peculiar galaxies in the sky, and is a strong source of radio radiation (therefore the designation Centaurus A); it is actually the nearest radio galaxy. It is of intermediate type between elliptical and disk (spiral) galaxies: The main body has all characteristics of a large elliptical, but a pronounced dust belt is superimposed well over the center, forming a disk plane around this galaxy.

This galaxy seems to have "eaten" at least one larger spiral in the last few billion years. However, the present author is not sure if this alone explains the unique appearance of this galaxy: It may well be that this is one of the rare "links" between "normal" ellipticals and "normal" disks.

In the radio part of the spectrum, Centaurus A exhibits two vast regions of radio emission, starting in prolongation of the polar axis of the disk of NGC 5128 and extending many hundreds of light years to each side. (Source SEDS)
