Quasars are bright objects that are believed to be black holes with hot gas swirling around them. The hot gas emits radiation as it spirals into the quasar's black hole. Astronomers study this radiation in order to understand the motions and properties of the black hole composing a quasar. This article studies the radiation emitted by a quasar, and the results of this study give evidence that in this case, there are two black holes orbiting around each other. This article describes the measurements of this unique dynamic quasar believed to contain two black holes instead of only one.
