Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

making it twice as long as the width of the Milky Way. Even more surprisingly, the black hole that powers the quasar from which this jet erupts, designated J1601+3102, is relatively small.
