Hubble gives us this nice image of the globular cluster 47 Tucanae. As I have an affinity for globular clusters, so this was of particular interest. I was always of the school that globular clusters were mainly old stars with only a few new one mixed in. That still holds ture of course just not to the extent I thought.
Astronomers looking at this particular globular have been busy with some surpirising results. I can only suppose these results could hold true for all globulars (?); I’m not ready to concede that just yet but this is pretty coold stuff. I’ll let them explain.
