Albert, your wonderful images make my day :)
Here is a Hubble images of a central part:

and comments:
"...Resembling looming rain clouds on a stormy day, dark lanes of dust
crisscross the giant elliptical galaxy Centaurus A.
Hubble's panchromatic vision, stretching from ultraviolet through
near-infrared wavelengths, reveals the vibrant glow of young, blue star
clusters and a glimpse into regions normally obscured by the dust.
The warped shape of Centaurus A's disk of gas and dust is evidence for a
past collision and merger with another galaxy. The resulting shockwaves
cause hydrogen gas clouds to compress, triggering a firestorm of new star
formation. These are visible in the red patches in this Hubble close-up.
At a distance of just over 11 million light-years, Centaurus A contains the
closest active galactic nucleus to Earth. The center is home for a
supermassive black hole that ejects jets of high-speed gas into space, but
neither the supermassive black hole or the jets are visible in this
image..."
Thank you
Victor
