The Ghosts of Galaxies Past brings up an astronomical feature I was previously unaware of: stellar streams (also called tidal streams), remnants of dwarf galaxies that have been caught in the gravitational pull of the a larger galaxy. These rivers of suns eventually merge with their captor galaxy, but stand out from their neighbors with a slightly different chemical composition; the Arcturus stream and the Virgo Stellar Stream are examples of such galactic immigrants.
