Some stars race through space faster than a bullet — their speeds reach thousands of kilometers per second. These 'runaways' help astronomers map the gravity of the Milky Way and find clusters of invisible dark matter.

🎯 One of these stars is racing at 1,200 km/s — fast enough to travel from Earth to the Moon in five minutes.

🎬 Fast stars leaving the Galaxy evoke generation ships from science fiction, where the stars themselves are the eternal travelers.
