Alien invaders pack the Milky Way
Royal Astronomical Society (PN 10/09) - 2010 Feb 23

Around a quarter of the globular star clusters in our Milky Way galaxy are invaders from other galaxies, according to a team of scientists from Swinburne University of Technology in Australia. In a paper accepted for publication in Monthly Notices of the Royal Astronomical Society, Swinburne astronomer Professor Duncan Forbes has shown that many of our galaxy’s globular star clusters are actually foreigners - having been born elsewhere and then migrated to our Milky Way.

The US is a nation of immigrants, by and large, and now it seems as if the Milky Way galaxy has its share of immigrants, too, in the form of globular star clusters. A new paper from Australian scientists at Swinburne University of Technology demonstrates that a significant chunk of our galaxy's star clusters were born elsewhere in the universe, and kind of migrated to the Milky Way. Or, as astronomer Duncan Forbes put it, they're "not natives, but aliens from other galaxies."
