Centaurus A is a well studied radio galaxy (active galactic nucleus). The central dust lane is the result of the collision and merging with a smaller spiral galaxy. Some features and effects (e.g., triggered star formation) of the relativistic jets can be seen in the image (in the 10-11 o'clock position).

A crop of the center in 150% resolution is given below.
