If you track the motion of individual stars in the ultra-dense star cluster at the very center of the Milky Way you’ll see that they swing in sharp orbits around some vast but invisible mass—that’s the Sagittarius A* supermassive black hole. These are perilous orbits, and sometimes a star wanders just a little too close to that lurking monster, leading to its utter destruction in the spectacular phenomenon known as a tidal disruption event. We’ve never seen a TDE in the Milky Way, but we’ve seen them in distant galaxies—and we now know how to spot stellar destructions so extreme that they reveal properties of the black hole itself.
