I don't know but found this article Originally posted to sci.astro on Dec 10, 2000. http://stupendous.rit.edu/richmond/answ ... bclus.html. If these clusters of millions of stars have cleared or lost the dust cloud does that not still make them galaxy's and should be added to the different types ...
