No one is sure, but it is likely related to an active supermassive black hole at its center. ... Detailed analyses indicate that the central galaxy, also known as 3C 348 , is actually over 1,000 times more massive than our Milky Way Galaxy, and the central black hole is nearly 1,000 times more massive than the black hole at our Milky Way's center. ...

... 2014 February 24 . The Cloudy Cores of Active Galaxies . Image Credit: NASA's GSFC , W. Steffen ( UNAM ) . Explanation: What would it look like to travel to the center of an active galaxy? Most galactic centers are thought to house black hole s millions of times more massive than our Sun. The spaces surrounding these supermassive black holes may be far from dormant, however, flickering in many colors and earning the entire object class the title of Active Galactic Nuclei (AGN). ...

Is the violent behavior of quasars caused by black holes in galaxies? If so, does the discovery of black holes in the centers of many normal galaxies mean that all galaxies were once quasars? ... If this is the case, then normal galaxies should still have massive black holes in their nuclei, like quasars, but these black holes should now be starved of fuel. ... What we do not yet know is what fraction of all normal galaxies once passed through a quasar phase. ... Scientific American. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
