The origin of most galaxies is not uniform, but run in several stages. This is a study of over 900 globular clusters by an international research team. The star clusters from the dawn of galaxy formation to occur mostly in two different chemical variants, the astronomers reported in the journal "Monthly Notices of the Royal Astronomical Society".

"This indicates presence of two types of globular clusters suggest that most large galaxies have gone through two phases of star formation through", Christopher Usher of the Swinburne University of Technology in Australia write Hawthorn and his colleagues.
