This is gonna be fun when it happens.
When a galaxy eats another galaxy it's called "Galactic Cannibalism". But what if a galaxy eats a galaxy that ate another galaxy, which maybe ate another ... we're getting into Russian nesting dolls here. Emily gives all the latest on new evidence of galactic cannibalism in our local neighbourhood, galaxy-wise, in the form of strangely ancient globular clusters.
