The gravitational pull of a suspected super-massive black hole forms a frisbee-like disk of cool gas, at the core of an energetic galaxy. Subsequent Hubble observations of yet another active galaxy (M87) confirmed the reality of monstrous black holes - gravitational "sink holes" that trap everything, even light.
