Astronomers using ESO's MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely. It appears to be orbiting an invisible black hole with about four times the mass of the sun -- the first such inactive stellar-mass black hole found in a globular cluster and the first found by directly detecting its gravitational pull.
