A black hole, rendered by integrating null geodesics through Schwarzschild spacetime — one per pixel. The halo above and below the shadow is the far side of the accretion disk, its light bent over the poles to reach you; the disk burns blue where the plasma races toward you, and reddens where it recedes.
