The Case of the Stolen Stars - Universe Today
At some point in the distant past, our own Milky Way robbed the low-mass stars from globular cluster M12. This cluster is about 23,000 light-years away in the constellation of Ophiuchus, and it's known to contain about 200,000 stars. What's unusual is that they're nearly all 20 to 80% the mass of our Sun; a surprisingly high ratio compared to the rest of the Milky Way. Astronomers estimate that M12 has ejected more than a million stars into the galactic halo, never to see them again.
