Graphics: VLBA Locates Origin of Superenergetic Bursts Near Giant Black Hole
Peering Deeper Into the Core of M87: At top left, a VLA image of the galaxy shows the radio-emitting jets at a scale of about 200,000 light-years. Subsequent zooms progress closer into the galaxy's core, where the supermassive black hole resides. In the artist's conception (background). the black hole illustrated at the center is about twice the size of our Solar System, a tiny fraction of the size of the galaxy, but holding some six billion times the mass of the Sun.

Artists's Conception of M87's inner core: Black hole, accretion disk, and inner jets.
Large-scale VLA image of M87: White circle indicates the area within which the gamma-ray telescopes could tell the very energetic gamma rays were being emitted. To narrow down the location further required the VLBA.
"Light Curves" of very-high-energy gamma rays and radio waves emitted by M87, showing that radio flare followed gamma-ray flare.
