Scientists believe each hypervelocity star began as part of a binary pair of stars near the center of our Milky Way galaxy, where extreme gravity from a supermassive black hole sucked in one star in the pair and, like a bolo, simultaneously hurled the other star -- a new hypervelocity star -- toward the edge of the galaxy.
