The National Science Foundation’s (NSF) Karl G. Jansky Very Large Array (VLA) image of the central region of the powerful radio galaxy Cygnus A, showing the doughnut-shaped torus surrounding the black hole and accretion disk. Astronomers used the VLA to make the first direct image of the dusty, doughnut-shaped feature.
