Cloud 9 is a failed galaxy. It’s a clump of dark matter, called a dark matter halo, that never formed stars. But this failure could be the key to a mystery almost as old as the universe itself: dark matter. Scientists don’t know what dark matter is, but Cloud 9 could offer new clues. Three researchers weigh in on this new discovery and why it could be a missing piece to the story on how the universe formed.
