ESO’s Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision—the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its center lies the closest pair of supermassive black holes ever found, two objects that are destined to coalesce into an even more massive black hole.
