Utilizing the powerful Hubble Frontier Fields observations of galaxy clusters, a study demonstrates that intracluster light — the light of stars orphaned in galaxy cluster mergers — aligns with dark matter, tracing its distribution more accurately than other methods. With broader use, astronomers think the technique could be a first step in exploring the nature of the unobservable, elusive dark matter that makes up the majority of the universe.
