Ten billion years ago, when the Milky Way was still forming itself, another galaxy collided with it and was consumed — leaving behind a ghost woven into the very fabric of our cosmic home. Scientists have now named that ghost Heracles, identifying its remnants hidden deep within the galactic core by reading the chemical memories and movements of ancient stars. The discovery, made possible by infrared light that cuts through dust clouds impenetrable to ordinary telescopes, reminds us that the galaxy we inhabit is itself a graveyard of worlds that came before.
