Thanks to the extraordinary sensitivity of the Karl G. Jansky Very Large Array (VLA), astronomers have detected what they believe is the long-sought radio emission coming from a supermassive black hole at the center of one of our closest neighboring galaxies. Evidence for the black hole's existence previously came only from studies of stellar motions in the galaxy and from X-ray observations.
