Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant object detected by the NuSTAR X-ray space telescope (which launched in 2012) and stands as one of the most highly 'variable' quasars ever identified.
