Colombari [6] and R. Gendler [7] Explanation: What's happening at the center of spiral galaxy M106? A swirling disk of stars and gas, M106 [8] 's appearance is dominated by blue spiral arms and red dust [9] lanes near the nucleus, as shown in the featured image [10] .. The core of M106 [11] glows brightly in radio waves [12] and X-rays [13] where twin jets have been found [14] running the length of the galaxy. An unusual central glow makes M106 [15] one of the closest examples of the Seyfert class of galaxies [16] , where vast amounts of glowing gas are thought to be falling into a central massive black hole [17] . M [18] 106, also designated NGC [19] 4258, is a relatively close 23.5 million light years away, spans 60 thousand light years [20] across, and can be seen with a small telescope towards the constellation [21] of the Hunting Dogs ( Canes Venatici [22] ).
