Astronomers have identified dozens of runaway stars moving fast enough to escape the Milky Way. By tracking these hypervelocity stars, researchers can map the galaxy’s gravitational pull and better understand how dark matter is distributed across its vast halo, offering new insight into the unseen structure shaping our cosmic home.Astronomers have identified dozens of runaway stars moving fast enough to escape the Milky Way.
