Split-Personality Elliptical Galaxy Holds a Hidden Spiral

giant elliptical galaxy Centaurus A

The giant elliptical galaxy Centaurus A shows a split personality because it hides a gaseous spiral at its core. When Centaurus A collided with a spiral galaxy 300 million years ago, it slurped up the spiral's gases, which formed a new spiral inside the larger galaxy.
