Web2 days ago · This activity is called a quasar, a phenomenon that happens when black holes emit an enormous amount of light across the electromagnetic spectrum as they feast. J0749+2255 is highly unusual because the system has not one, but two quasars that are active at the same time, and are close enough that they will eventually merge.
