The astronomers estimated that the "ultramassive" black hole is over 10,000 times the mass of the Milky Way's black hole.

The massive "Cosmic Horseshoe" galaxy system likely hosts a colossal black hole measuring 36 billion times the mass of our sun — one of the largest ever seen in the universe, a new study finds.
