2. On the website, there is much clear evidence of a black hole in the central region of the Virgo cluster galaxy M 87. The first picture shows a spiral shaped hot gas at the core of our active galaxy. The gas is rotating so rapidly that there must be a black hole at the center. The region M 87 fits the description of a black hole. It weights as much as three billion suns, but is concentrated into a space no larger than our solar system. This strong gravitational pull towards the center is clear evidence of a black hole. Also, a jet of high-speed electrons which are emitted from the nucleus are predicted to be produced by the black hole "engine". In the second picture, they measured the light from the disc and studied when it was red-shifted and blue-shifted. The gas on the side that is spinning away from the earth is moving 1.2 million miles per hour. The gas on the opposite side that is moving towards the earth is moving in the same direction. These high velocities!

Supermassive Black Hole comes from Doppler shift of ionized gas in its v
