Galactic serial killer: Galaxy engulfed several other galaxies in its violent history

A new image shows two contrasting galaxies: NGC 1316, and its smaller neighbor NGC 1317. These two are quite close to each other in space, but they have very different histories. The small spiral NGC 1317 has led an uneventful life, but NGC 1316 has engulfed several other galaxies in its violent history and shows the battle scars.
