MarkS Posted April 21, 2015 Report Share Posted April 21, 2015 Omega Centauri is the largest globular cluster in the Milky Way. It contains about 10million stars with a total estimated mass of 4million solar masses. It is estimated to be 12 billion years old, and there is some speculation as to whether it is the core remnant of a dwarf galaxy captured by the Milky Way. There is also some evidence to suggest that there is a black hole at its centre, although this is disputed. Viewed from earth, it is approximately the size of the full moon. It is 15,800 light years away and its diameter is about 150 light years. It is some distance off the Milky Way disc, and there are no really bright stars in the vicinity. This image was shot last night from our property north of Melbourne. Not a great night - very windy; some cloud interference; best SQL reading 21.3. But there are 2hours 20min of RGB data.
