Viewed nearly face-on, the galaxy, called Markarian 817, shows intense star-forming regions and dark bands of interstellar dust along its spiral arms. Rings of brilliant blue stars encircle the bright, active core of this spiral galaxy, whose monster black hole is blasting material into space at 9 million miles an hour This discharge is being powered by a huge disk of matter encircling the supermassive black hole, which is 40 million times more massive than our Sun. The disk is driving the material out of the galaxy through powerful winds, produced by streams of charged particles. Markarian 817 is 430 million light-years away in the northern constellation Draco.
