... 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). ...
