Intergalactic Dismemberment

Scientists think they may have discovered the dismembered remains of a galaxy trailing in our own's wake. That is one hypothesis which could describe how the globular cluster NGC 2808 ended up with three distinct generations of stars inside it instead of the far more common one. The thinking goes this may have been a dwarf galaxy that was taken apart by the Milky Way's gravity billions of years ago.
