Fig13_10 Supermassive Black Hole NGC 1097

Fig. 13.10 . This barred spiral galaxy, designated NGC 1097, is located about 44 million light-years from Earth. It is a Seyfert galaxy and a moderate example of an Active Galactic Nucleus, or AGN for short, with jets shooting out of its core. A super-massive black hole, with about 100 million times the mass of the Sun is located at the center of the galaxy. As shown in this infrared view of NGC 1097, taken from the Spitzer Space Telescope, a star-forming ring surrounds its center. As gas and dust spiral into oblivion in the central black hole, they cause the ring to light up with hundreds of new stars. The galaxy’s spiral arms and the swirling spokes between them show dust heated by other newborn stars, as well as older stars. (Courtesy of NASA/JPL-Caltech.)
