Omega Centauri: This ultimate high-light of the southern sky is never ending to amaze one with its millions of stars.
Two different populations of stars (younger blue ones and older yellowish ones) together with the recent discovery of a medium sized Black Hole within Omega Centauri seem to indicate that this object was not evolving from a cluster of densely packed stars, but from a dwarf galaxy. This was captured by Milky Way and stripped of many of its stars. But by the mutual exchange of matter also new generations of stars could have been generated.
The image was taken at the observatory of IAS at Hakos Farm in Namibia.
