"Surprising Discovery: 2nd Black Hole Found Orbiting 'Hiccupping' Black Hole"

TL;DR
Astronomers have observed a distant supermassive black hole exhibiting periodic "hiccups," which are caused by a smaller black hole orbiting around it and disrupting its accretion disk. This discovery suggests that black hole accretion disks may host a variety of cosmic objects, including other black holes and stars. The researchers anticipate that the immense gravity of the supermassive black hole will eventually merge with its companion black hole. This finding challenges existing knowledge about black hole systems and may lead to the discovery of a new population of extreme binaries.
