by The nearby radio galaxy M87, located 55 million light-years from the Earth and harboring a black hole 6.5 billion times more massive than the sun, exhibits an oscillating jet that swings up and down with an amplitude of about 10 degrees, confirming the black hole's spin.
Supermassive black holes at the center of active galaxies—the most disruptive celestial objects in our universe—can accrete tremendous amounts of material due to the extraordinary gravitational force and power of plasma outflows, known as jets, that approach the speed of light and extend thousands of light-years away.
