Astronomers have detected the fastest-growing black hole. The new supermassive black hole is known as J1144. J1144 is 3 billion times more massive than the sun, it swallows up an Earth-size chunk of matter every second.
Sagittarius A* is located at the center of our galaxy, it has a diameter of 44 million kilometers. J1144 is not only 500 times bigger than Sagittarius A*, but also 7,000 times brighter than our entire galaxy.
Astronomers believe that something catastrophic happened long time ago. Perhaps two big galaxies crashed into each other merging the Black holes located at their center. Also funneling a whole lot of material towards it.
