The AGN sits at the center of the galaxy, is extremely bright, and emits radiation across the entire electromagnetic spectrum as the supermassive black hole at its core devours material that gets too close. Hubble Observes an In-between Galaxy: NASA’s Hubble Space Telescope captured an image of the lenticular galaxy NGC 3489, which has an active galactic nucleus, or AGN.These monsters lurk in the centers of most big galaxies, including our own Milky Way, and contain between 100,000 and tens of billions of times more mass than our Sun. NASA Animation Sizes Up the Universe’s Biggest Black Holes: A new NASA animation highlights the “super” in supermassive black holes.Credit: NASA's Goddard Space Flight Center Conceptual Image Lab Scientists think all of these objects shine most intensely in ultraviolet light. Smaller black holes are shown in bluish colors because their gas is expected to be hotter than that orbiting larger ones. Only one of these colossal objects resides in our own galaxy, and it lies 26,000 light-years away. The black holes shown, which range from 100,000 to more than 60 billion times our Sun’s mass, are scaled according to the sizes of their shadows – a circular zone about twice the size of their event horizons. Watch this video to see how they compare to each other and to our solar system. S2CID 119197147.All monster black holes are not equal.
