Globular Star Clusters
Globular Star clusters are massive concentrations of stars that orbit a
common centre of gravity and are very tightly bound together; giving
them their spherical shape and high stellar density. In the
southern hemisphere we are blessed with the biggest and brightest of all
globular clusters; Omega Centauri. A 2 million star globular with a
black hole at its centre.
The origins and galactic evolution of globular clusters is still
unclear. For example, Omega Centauri has a bunch of massive hot blue
stars that are younger than the other stars in the cluster, indicating
these may have been captured and join the cluster at a later date.
Intrigue and mystery aside, likes check have a look at some Southern
Hemisphere delights.
