Just as gas interacting with a stellar black hole causes fireworks, the interaction of gas and stars falling into a supermassive black hole, circling faster and faster as they approach, cause explosions of gas traveling near the speed of light to shoot out from the core region. These jets are visible in radio light and were discovered with high resolution radio observations around many galaxies in the late 1970's. In the image above, the galaxy itself is coincident with the tiny little dot in center, between the two enormous radio lobes. In the drawing is shown the accretion disk, the gas and stars swirling together very fast as they approach the even horizon of the supermassive black hole. |
