NASA animation sizes up the universe's biggest blackholes NASA
This frame from NASA’s new animation compares the sizes of three supermassive black holes in relation to planetary orbits in our solar system. At top left, unlabeled, is the black hole at the center of the Circinus galaxy. Below it lies the giant black hole in galaxy M32. And at right is the more massive black hole at the heart of our own Milky Way galaxy.
In 2019 and 2022, a planet-spanning network of radio observatories called the Event Horizon Telescope produced, respectively, the first images of the giant black holes at the centers of M87 and the Milky Way. They revealed a bright ring of hot orbiting gas surrounding a circular zone of darkness.—the black hole's point of no return—becomes trapped forever, and any light passing close to it is redirected by the black hole's intense gravity.
First up is 1601+3113, a dwarf galaxy hosting a black hole packed with the mass of 100,000 suns. The matter is so compressed that even the black hole's shadow is smaller than our sun.
