In this image, we look back to when our universe was much younger and more violent. Each pinprick of color represents a supermassive black hole - some several billion times more massive than our Sun. Not even light can escape the clutches of a black hole, but the material around its edges heats up and emits strong X-rays, alerting us to the black hole's presence.
