Galactic bloodlines: Many nearby star clusters originate from only three 'families'

An international team of astronomers led by the University of Vienna has deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team, led by Cameren Swiggum and João Alves from the University of Vienna and Robert Benjamin from the University of Wisconsin-Whitewater, reports that most nearby young star clusters belong to only three families, which originate from very massive star-forming regions.
