Scientists have discovered a large black hole that "hiccups", and emits gas fluxes. Analysis revealed that a small black hole repeatedly punctures the gas disk of the large black hole, causing the perturbations to be released. Strong magnetic fields, north and south of the black hole, shown by the orange cone, shoot the flux up and out of the disk. Each time the small black hole punctures the disk, it emits another star, in a regular periodic pattern. Credit: Jose-Luis Olivares, MIT
