NASA Animation Sizes Up the Biggest Black Holes

video: All monster black holes are not equal. Watch this video to see how they compare to each other and to our solar system. 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. Only one of these colossal objects resides in our own galaxy, and it lies 26,000 light-years away. Smaller black holes are shown in bluish colors because their gas is expected to be hotter than that orbiting larger ones. Scientists think all of these objects shine most intensely in ultraviolet light. Note: This version corrects a mislabeling of the orbit of Saturn. view more
