Spiral Gas Disk in Active Galaxy M87
A NASA Hubble Space Telescope image of a spiral-shaped disk of hot gas in the core of active galaxy M87. HST measurements show the disk is rotating so rapidly it contains a massive black hole at its hub. A black hole is an object that is so massive yet compact nothing can escape...

Hubble Measures Velocity of Gas Orbiting Black Hole
A schematic diagram of velocity measurements of a rotating disk of hot gas in the core of active galaxy M87. The measurement was made by studying how the light from the disk is redshifted and blueshifted – as part of the swirling disk spins in earth's direction and the other...
