These are the clever messages headed to Jupiter aboard NASA’s Europa Clipper

Scientists have found a large black hole that “hiccups,” giving off plumes of gas. Analysis revealed a tiny black hole was repeatedly punching through the larger black hole’s disk of gas, causing the plumes to release. Powerful magnetic fields, to the north and south of the black hole and represented by the orange cone, slingshot the plume up and out of the disk. Each time the smaller black hole punches through the disk, it would eject another plume, in a regular, periodic pattern. Credit: Jose-Luis Olivares, MIT
