Doughnut-shaped object surrounding supermassive black hole

Artist's conception of a dusty, doughnut-shaped object surrounding the supermassive black hole at the core of one of the most powerful radio galaxies in the universe -- Cygnus A; the disk of material orbiting the black hole; and jets of material ejected by the disk at the center of a galaxy. Astronomers used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to make this first direct image of the dusty, doughnut-shaped feature.
