While researching a potential counterpart to an observed gravitational wave event, astronomers identified the signal of an event never before identified: the radio “glow” of a black hole cracking apart a sun or other major body that had wandered too close to it, IFLScience reports.
This black hole, about 10 billion light-years from Earth, is thought to be having a “tidal disruption event” where a sun, system or other stray collection of material reaches a point where the material structures of the bodies start breaking apart, casting off a signal. It could turn into a larger “active galactic nucleus,” where a black hole at the center of a galaxy “turns on” a feeding frenzy after having been relatively dormant for a period.
